I redacted the original post on production number body number stamps as a respected 964 expert advised me that criminals shouldn't have access to more info on how to rebirth stolen cars. These numbers amongst other things are used to expose stolen and faked cars.

While I was looking for dashboard numbers I decided to tackle the knee pad dent. I have no idea how the dent got there. Maybe something heavy was stored in the car and it deformed the pad. Anyway a local repairer suggested gentle use of a heat gun. It worked perfectly. As soon as heat was applied the vinyl returned to its original shape.

New ARB brackets for the White car. USD 20 for the pair. They took all of thirty minutes to fit. Now the car could be moved on to the lift it was time to find the source of the engine oil leak. It looks like it's coming from behind the pulley.

I have had a frustrating time tracking down the engine leak on the White car. Long story short it's leaking in two places: the case area around the nose bearing and also the intermediate shaft cover below it. In hindsight this area has leaked since the full OPC rebuild.
The intermediate shaft cover has been hit by a ball peen hammer in the past so I have ordered a new cover and o ring. That's the easy part. The big problem is the nose bearing area as this is sealed by an o-ring inside the case. There are solutions to seal this area from the outside, the Tom Amon collar was one of them, and it didn't work. Rather than try a similar solution I'm going to reseal the motor and stop the oil leaking out. Yes, I'm going to spend 40 odd hours in labour to pull the engine apart, split the case, replace a cheap o-ring and put it all back together. This type of work was on my bucket list but I wanted to do the Silver car, not repeat work I paid an OPC good money to do.

If you are looking for inspiration on 964 engine work check this out. http://perelet.com/cars/porsche/leaks_thread/1.html
Oleg is even fitting his own valve guides (page 4), a task OPCs farm out.

That great thread is what started it all for me, two summers ago...
So, this will be a open, basically, disassemble short block and all components inside, clean case halves, reassemble, etc., correct?

I will dissemble everything required to replace the nose bearing o-ring, which is pretty much a complete strip down. I will inspect the various parts but I won't go overboard as this engine was fully rebuilt only 12,000 miles ago. Not sure on the cleaning method yet.

From the twilight zone. Past experience with an engine drop told me to get as much oil out of the system as possible before dropping it, otherwise it would slowly leak out of capped pipes etc.
I did this for a couple of days. When looking through the oil from the tank I found paper!!!!!
Now, a mechanic has told me that the oil tank is very difficult to fully flush out so this paper could be the same as found in 2013 (see the link to lessons learned on page one of this thread) I.e. don't panic.
However, this is the weird part. The paper I assumed got into the system was a kitchen paper towel, BUT this paper has writing on it. Looking back there is a real possibility this car had paper in the system when I bought it. This is too weird to make up, especially as the text looks like it has religious overtones. Maybe I should call the car Damien?

The paper mentioned above.
Did the previous owner sabotage the car? I don't know but I'm very happy that I have the motivation to sort the engine out myself once and for all.
