New 3/4" tools arrived. I'll tackle the driveshafts on the weekend. Any tips out there for C4 front drive shafts?

John McM

The CV joint job is finished, hopefully.

I used the method that disconnects the strut from the top mount point.

I won't repeat what's in other threads except to note the following I wish I'd known

1. The front axle nut needs a 3/4" socket and wrench. The torque setting of 330 ft lbs exceeds 1/2" specs so tools with that size are likely to break. Ask me how I know!

2. After you have undone the circlip the joint is able to be pulled off. In my case the puller took the joint outer off, not the core, so it all fell apart. I'd like to see what technique people use to get a puller around the joint outer to hook the core.

3. The grease used in CV joints is beyond messy. It gets everywhere.

4. If your joint disassembles, watch a video on reassembling it before you attempt it. I used the method posted by a 996 owner. I have no idea how some do this while the driveshaft is on the car.

5. The CV boot clamp join position must not coincide with a bolt position, otherwise it's hard to get the bolt on.

6. Be very careful tightening the driveshaft flange bolts. Get the tool fully inserted and square. You don't want to round out the bolt otherwise you will need a dremel to cut the bolt head off. The torque is 32ft lbs.

7. The front and rear CV inners on a C4 are not the same part. I now have two rears as spares :/

8. The front and rear axle nuts on a C4 are not the same. The rears are inexpensive, the fronts aren't. One of mine is not holding the full torque so I'll replace it.

9. There is no aftermarket CV joint for the front inner on a C4. The Porsche part is so expensive that you might as well buy an entire driveshaft.

And the excessive packing award goes the seller that packaged two seat driveshafts (in the image) in a box big enough to take a flywheel.

I watched this video and searched the net for a supplier of the tool.

In my search I found these which I hope will both store touch up paint and apply it.

John please let us know what you think of this applicator. I currently use the toothpick method but I am always open to trying different products that could do a better job.

Judging by how fine the tip is I'm sure it will need to be flushed immediately after use to prevent plugging but should be reusable otherwise.

Edit: I just bought the Leow Cornell tool and wil give it a shot. It adds the same amount as a toothpick but doesn't require paint refills which is a plus!

John McM

Will do. A feature of this tool is a fine needle in the cap. This cleans out the applicator nozzle when placed back on after use.

I bought fine and standard versions as I'm not sure how paint will flow through them.

Another purchase was pre cat flanges from Bisimoto. I suspect these are made to help repair rusted out exhausts. My use is different. These will be the flanges anchoring a modified cat bypass with a cut off valve. I will hopefully be able to run a normal exhaust most of the time but change to full noise at the push of a button

This appears to be the tool for CV joint removal. The only problem is that it's designed for an outer CV joint and uses the driveshaft and axle nut to pull it. That won't work with an inner.

New front driveshaft has arrived. A relative bargain considering it's Porsche original. Plus a couple of front axle nuts.

David Burggraaf (Rennlist handle Maxem) has delivered his second pre production billet 964 Valve covers. Still a few items to add like wire clip studs in the final version but this lot are going on my car as is to test them. Time to seal up my engine.

Hi John. In post 825 there are 2 bright shiny red valve covers sitting on the bench in the background. In this post you're comparing the new covers to what look like dull red covers which I assumed were on the engine previously. Has the engine been run and taken the 'shiny' off? Just wondering what might have happened to valve cover coating.

Cheers,

Dan

Hi Dan,

The red powder coating has always been a dull matte finish. I think it looks even moreso under the light I used for the later photos. I’m thinking about what finish to use on the billet covers and may go for an anodised coating this time. The reality is that past the initial show photos these live in a dirty environment so a muted colour scheme works best.

Final check of valve timing. Carefully fit the plugs, then new valve covers. Finally make sure the plug wires are well connected.

Very nice John !!

My engine is close behind. Should be working on the install in another week or two.

Fan belt installed. The hex head bolt is only torqued to 10 Nm.

Krikit tool allows belt tension measurement. 25kg is correct for a cold used belt.
