Back from sere...block has been decked and cleaned. Took 6 thous off. Still have to get it picked up, but in the mean time I epoxied the garage in prep for rebuild and easier clean up.

Before and after.







Also returning to Jersey shenanigans is a struggle as shown from simultaneous front and rear photos.

So, how much lighter are you now?

Good luck with this, I'll be following it. My mileage is high and major work is inevitable, though having done a head gasket on mine and many other projects on/around the block, I can say that mine is not 'frankensteined' like yours.

That sand in your oil cooler was definitely leftover debris from a head gasket failure - a HG that probably corroded quite a bit before blowing out.

Interesting about the origins of the sand. Never thought of that.

I came back from the woods about 5lbs lighter, then back from resistance about 10. Now I'm back to normal physically.

Meanwhile if anybody has an oil pan and oil pickup they want to part with, let me know

I would like to have the engine balanced. I've armchair researched this through this forum and Google/other forums and it seems like people try anything from just buying a digital scale and making a jig to balance the pistons, rods, rings, and pins to using a machine to enter all the numbers then it formulates where and how much material to take off. All options have seemed to offer good results whether it's an expert balancer judging or the shade tree rebuilder, so my curiosity is what seems the best method for owners of this vehicle?

Well here is the disappointment of the day. After 4 weeks, I finally get to pick up the block. Here is the result. When I picked it up the owner seemed like he just wanted to get rid of it and his employees seemed shameful.









He said they used safety kleen and it couldn't remove it. The cylinders now look stained and worse than before. Don't know if that is bad or not. I may just send this out to get honed properly, unless it is good then i'll just go in by hand with a small brass brush and get rid of that sandy stuff.

The guy saw my disappointment and told me to take the block and leave, but I still paid him the price we originally agreed on. $100 for the decking, but not pleased.

i'll put my money on it, they haven't ever cleaned an alusil block. diesel is good to clean with. brush it on, let it soak a bit, wash it off.

PorscheFanatic202

He also told me the cylinders were glazed over, which granted if you don't know about the block isn't common knowledge because normally you would have cross hatches, but I think he assumed it was going to be honed

Lesson learned today....seek someone who has done this before like Chris

dizzyj

ugh..thats just unreal. do you think the block is finished, or can be cleaned/fixed by someone who knows what they are doing? thankfully a good 951 block is not too hard to come by

Paulyy

It's the shops responsibility to give you what you asked for. If they've damaged anything and it's not written down on your invoice that they don't take responsibility for any damages they caused, they should be fixing your block, or be paying for the repairs.

PorscheFanatic202

I don't think it is ruined, perhaps it might just need a hone at most. I'll put some diesel on it to soak

Paulyy

You might be a little more lenient compared to me. But if i give my engine block to a shop to clean. I expect it to be clean, not worse.

I hope your cylinders are okay. Make sure when you get them honed, you get someone who's done Alusil bored before.

Have a read.

Diesel should work. that got all the oil off and gave mine a good clean.
Also get some washing stuff from the laundry and try on parts of the block and see if it helps.

Chris White

Looks like the decked the block with a used chain saw blade....
Make sure when you are all done that you pull out the oil galley freeze plugs and clean out the oil galley. Just a little trash in there will ruin your whole day when you start up the new engine!

I thought it looked pretty bad too. It feels smooth though. I'm getting some small brushes and a pipe cleaner to clean it out. I'm just torqued off because it looks like they didn't even try to clean it other than just running some safety kleen over it

You'll need to actually measure the surface finish. There is a tolerance requirement for the finish, and if it's out of spec, the head gasket might not seal up. Which head gasket are you going to use - stock or cometic?
