A couple of weeks ago, I completed this repair using Greg (Brown) and Steve's newly developed block repair tool. I picked up the tool from Greg at Sharktoberfest and started the repair the following weekend. It took me approx. 2 weekends to disassemble, effect the repair, and reassemble. Someone more experienced than I could certainly do it in a long weekend, I believe. Here's the link to the thread I started when the failure was first noticed - it includes pictures of the damaged block and the defective rebuilt water pump: https://rennlist.com/forums/928-foru...ater-pump.html
I found the instructions that Greg provided to be EXCELLENT! Since I'm not a pro wrench, I read through the instructions 2-3 times completely before starting while comparing the descriptions and pictures to the parts/tools supplied in the kit. Then, while making the repair, I double checked everything before cutting/drilling to minimize mistakes. Although the repair seemed tedious, it is definitely doable WITH patience.
The quality of the kit was GREAT. Everything was clean and extra bits are supplied in case they are dulled during use. All in all, it was a great experience and I'm happy to report the temperatures are lower than before the repair (although I have to qualify that statement since I no longer have 100 degree ambient temps to compare to the baseline reading I had previously - guess I'll have to wait until spring/summer for the true check).
I thought I'd share the process I used for those interested in this repair. It should be very close to the instructions supplied with the kit. Greg's instructions were excellent and I really can't add anything to his instructions (except a few pics, of course!). This sequence of pics assumes you already have the front of the engine disassembled with the water pump removed.
Normally, you would not remove the upper radiator hose elbow pipe for a TB/WP removal but I found it easier to have it out of the way for this repair.

You will also need to remove the radiator if you use the supplied drill (which I did).

Next, I stuffed the main coolant opening with shop towels in an attempt to keep the filings and oil out of areas I didn't want.

With these out of the way, you should have clear unobstructed access to the water pump and block.

Next, I attached some duct tape to a plastic bag (garbage bag) and secured the tape under the water pump mating surface on the block in order to catch and deflect as much of the cutting oil as possible and keep it from getting on the lower section of the block. I also stuffed a small rag in the opening directly under the water pump mating surface and above the crank shaft since there was no surface to attach the tape to.

I did a test fit with the air drill just to see what type of clearance I would be working with. Plenty of room to work with the radiator removed.

Next, the depth of cut needs to be set. Loosen the collar on the cutter shaft. It uses an allen bolt.

In summary, the process goes something like this. Make an initial cut (0.074"). Then check the cut surface to see if you got all the damaged area cleared. If not, reattach the tool and set depth for an additional 0.010". Remove the tool and check to see if all damaged area has been cleared. If not, repeat taking 0.010" depth of cut each time until the damage is cleared. Inserts are supplied for each of these depths (e.g., 0.084", 0.094", 0.104", etc.). The first cut is made to a depth of 0.074". In order to get the depth set right, use feeler gauges in combination to equal 0.074". Make up two stacks at this thickness.

Then fit the feeler gauge stacks between the collar and WP casting as shown in the picture below. Hold the collar against the feeler gauges to hold them in place while tightening the allen bolt. To get an accurate depth of cut, press and hold the end of the cutter shaft against the block while holding the collar against the feeler gauges.

With everything held in place, tighten the locking collar in place. Greg suggests a tightening torque but I don't remember what it is since I did not keep a copy of the instructions - follow the torque recommendation in the instructions.

You will notice there should be a 0.074" gap now between the locking collar and WP housing. This represents the amount of travel the cutter will be allowed to cut.

You will notice cut openings in the WP casting for shavings to escape. I used these openings to squirt the cutting fluid since the bottle had a squirt-type cap. There is also a hole in the top of the WP casting to adding cutting fluid but I found these openings (indicated by the green arrows below) to be easier to add the cutting fluid.

Next, I added the cutting fluid. I would add plenty of cutting fluid (since I had a whole gallon of it) and added fuid between stops and also added fluid while cutting.

Then I started cutting. I set the air pressure to about 90 PSI. It operates pretty smoothly at first since the cutter is only making contact on a small portion of the damaged area initally.

After a few moments, some filings start to appear from the removed material. Greg's instructions are very good at detailing what to expect from the drill performance (chatter) and amount of filings to expect as you continue to drill. At first, small filings will appear since the edges of the damaged area are being addressed by the cutter first. Then, the filings get longer as you cut and clear larger, wider areas.

Next, I added the cutting fluid. I would add plenty of cutting fluid (since I had a whole gallon of it) and added fuid between stops and also added fluid while cutting.

Then I started cutting. I set the air pressure to about 90 PSI. It operates pretty smoothly at first since the cutter is only making contact on a small portion of the damaged area initally.

After a few moments, some filings start to appear from the removed material. Greg's instructions are very good at detailing what to expect from the drill performance (chatter) and amount of filings to expect as you continue to drill. At first, small filings will appear since the edges of the damaged area are being addressed by the cutter first. Then, the filings get longer as you cut and clear larger, wider areas.

Drill until the locking collar meets the WP casting. At this point, the cutter will turn fairly easily as it has removed all the material allowed by the locking collar. Disconnect the drill from the cutter shaft and remove the WP-to-Block bolts....

To prepare the tool and block for another cut, clean all the filiings from the mating surface on the block. You will want to have an acurate measure of cutting depth and making sure there are no filiings between the block and cutting tool housing helps ensure accurate cuts.

Now attach the drill again as before, tighen the drill chuck and drill while applying cutting fluid. This time, more material was being removed and the drill/cutter gave considerable chatter feedback. However, with a little practice, you can vary the pressure to minimize the chatter. After you have reached the cutting depth and the drill/cutter operate smoothly - indicating a smooth surface has been cut - you can remove the drill and remove the cutting device as before.

Dwayne, that is a stellar write-up! Good job! I think your engine is cleaner than any I've seen- really nice..
Thanks also to Greg Nettles for contributing the 1/2" air drill to this project. We are making more inserts now, and Greg B will have them this week.

Next, install the water pump without gasket. According to the instructions, when you apply the JB weld under the insert, it raises the insert outward. However, adding the WP gasket also moves the impeller outward. As long as the WP doesn't scrape here, it shouldn't scrape when applying the JB Weld and WP gasket.

Here's the drilling/tapping jig. You will notice 8 inserts all around. Four of them toward the outer edge (silver colored ones in the pic below) and the other 4 toward the inner edge (blue in the pic below). Each insert is held in place by a small allen head bolt. According to the instructions, the blue inserts are for drilling and the silver inserts are for tapping. The jig is set up for drilling the inner 4 holes first.

The jig is held in place with a block to the rear that is attached to the jig with a bolt that goes through the center of the jig as pictured below. Orient the jig as shown for installation into the center coolant port.

Since installing the jig is a little tricky, unscrew the bolt as far as you can without removing the bolt. Then angle the square end of the block down into the coolant port as shown.

With the nut still a little loose, install a couple of feeler gauges to help center the jig in the coolant port. You can use two gauges each about 0.008" or 0.009" thick. I used one 0.008" and one 0.009".

Next, clock the jig so the top outer insert (silver) is in the approximate 12:30 position. See arrow in pic below. This is to help minimize the number of holes that may "communicate" with the outer block. I wasn't quite sure what "communicate" with the outer block meant until I started drilling. It means punch through to the outside of the block. According to the instructions, there is no way to avoid at least one hole being drilled to the outside of the block. Potentially, you could have two holes communicating to the outside block if the jig is not oriented in this manner. The other area that punched through for me was near the top of the jig where the wall is very thin and the drill went through to the coolant neck (where the water/coolant bridge connects to the block. However, this is not a concern since it is not communicating with the outside of the block.

According to the instructions, the likely candidate to punching through is the insert located at the 2:30 position (see top green arrow below). However, when I drilled mine at this orientation, it was the insert at the 4:00 position (see bottom green arrow below) that punched through. It punches through at the thin wall that is between the impeller surface and the deep hole/pit that catches coolant and oil near the front of the engine (driver's side). You can actually feel the drilled through hole if your finger is long enough to reach down into the coolant/oil catch pit.

Drill the blue inner inserts first using the supplied drill bits. There are extra drill bits in case the one you start with gets dull. I was able to drill all 8 holes with a single drill bit. The instructions recommend keeping the used drill bit so it does not get mixed with the others and does not get passed along to the next user. I test fit the drill bit into the insert to see how deep I would be drilling. The instructions explain to drill down to the top of the cutting flutes of the drill bit (see green arrow in the pic below).

Then began drilling with slow steady pressure but not too much pressure. It is also best to position the drill bit all the way into the insert before starting to drill as this will preserve the sharpness of the drill bit. This seemed to work well for preserving the drill bit I was using.

That was my thinking, originally as well. However, I was going to follow the recommendation to use JB Weld on the back of the insert for the final installation. The JB Weld will effectively "add" thickness to the insert while the WP gasket effectively moves the impeller away from the insert. Since I was test fitting the insert without the JB Weld, I needed to also leave off the gasket to keep the measurements matched. Greg's instructions also provide measurements for the expected added elevation from the JB Weld (which I believe is significantly less than 0.010") and the approximate thickness of the WP gasket (which I believe is about 0.010"). After reading the instructions, it made sense to leave the gasket off for dry fit checks. If one were to not use the JB Weld for the final install and install the insert with screws only, then fitting the WP with gasket installed would make sense. Hope this helps. Thanks for the question!

Here's the tapping bit. I was lucky enough to have a 3/8" socket adapter that the tap would fit into (the kit does not come with the socket adapter). I used this to begin tapping. If you have a small "T" handle that will clear the block while using it in the application, that would be preferred over the socket method I used.

You will begin tapping using the silver colored inserts. I attached the tap to the 3/8" socket wrench and fitted the tap into the insert. To minimize possibility of bending force being applied to the tap while using the socket (and possibly breaking the tap), grip the socket head with your hand while turning rather than gripping the handle of the socket. It doesn't take a lot of force to turn the tap so gripping the head of the socket works fine

Carefully tap the hole using the wrench until you feel slight resistance from the tap bottoming out in the hole. You can also judge approximately when you are getting close to the bottom of the hole by comparing the distrance travelled to the same distance travelled when drilling the hole with the drill bit.

Here's the tapping bit. I was lucky enough to have a 3/8" socket adapter that the tap would fit into (the kit does not come with the socket adapter). I used this to begin tapping. If you have a small "T" handle that will clear the block while using it in the application, that would be preferred over the socket method I used.

You will begin tapping using the silver colored inserts. I attached the tap to the 3/8" socket wrench and fitted the tap into the insert. To minimize possibility of bending force being applied to the tap while using the socket (and possibly breaking the tap), grip the socket head with your hand while turning rather than gripping the handle of the socket. It doesn't take a lot of force to turn the tap so gripping the head of the socket works fine

Carefully tap the hole using the wrench until you feel slight resistance from the tap bottoming out in the hole. You can also judge approximately when you are getting close to the bottom of the hole by comparing the distrance travelled to the same distance travelled when drilling the hole with the drill bit.

After tapping all 4 of the inner holes, you will need to reconfigure the drilling/tapping jig for tapping the outer holes. First, loosen the allen head bolts on the dark blue inserts....

Performing the final tapping can be tricky in that you don't want to cross thread the holes you just tapped with the jig. I simply started the tap by hand, as shown below, by carefully wiggling and turning the tap to get it started in the hole.

I replaced the screw with another one from the kit that seemed to fit much better. There are small variances in manufacture of the screws and some have thicker head rims than others. By trying different screws and feeling the surface, I found one that fit. The kit also comes with countersink drill bits that you can use to further counter sink the holes in the insert but I was fortunate enough to simply find different screws that fit better than others. I repeated this test and replace screws cycle a few times until I ended up replacing about 3 screws.

I replaced the screw with another one from the kit that seemed to fit much better. There are small variances in manufacture of the screws and some have thicker head rims than others. By trying different screws and feeling the surface, I found one that fit. The kit also comes with countersink drill bits that you can use to further counter sink the holes in the insert but I was fortunate enough to simply find different screws that fit better than others. I repeated this test and replace screws cycle a few times until I ended up replacing about 3 screws.

After replacing any "high" screws, replace the water pump and secure it to the block as before to test again.

Turn the TB pulley and listen for any scraping sounds. Also try applying upward pressure while turning the pulley to simulate the pressure the TB will apply to the pulley. At this point, I could feel no more scraping from the screw heads.

Nice work.
Are the plate retaining screws made from stainless steel? Stainless steel is not very suitable for use with aluminum due to galvanic corrosion. A good screw material choice is galvanized steel or aluminum alloy. See chart at this link...

Course, you will never need to remove the screws, so any corrosion might serve to make them unremovable.

Now, you are ready to apply the JB Weld and install the insert permanently. First, since each screw is matched with each hole, mark one of the screw holes on the insert with a marker as shown. You will want to reinstall the screws in the same holes you remove them from.

Then remove the screws starting at the location you just marked. I moved clockwise from the marking on the insert. Make note of which hole in the block the marking is located.

Here's the JB Weld I used. The instructions recommend using the longer setting material (not the quick set type).
