I was thinking that. There is enough play in it that I might get a different turbo or have this unit rebuilt.

I know this is somewhat down the road, but do you know where to get a complete exhaust gasket/seal kit without spending over 100? I think it is ridiculous that they cost so much. Initially this was the issue I had. It expanded into so much more

Crazy Eddie

Isn't that always the case, with these cars?

I would do as much as you can afford .... It's money well spent, while you have the engine out.
When I did my rebuild, my car had only 47 K miles on it and I am the orig owner Then a wise soul told me," It's not just the miles but the time..."
I wish I had listened ...
These cars should be called, "While you in there cars "
Good luck

Just what I thought as I was reading this..

I'm looking into the turbine here soon. Anybody put a finger on the cause of ceramic breakdown? Excessive heat? Maybe knock?

PorscheFanatic202

Still need to look at turbine, but came across some other questions. The right-most hole nearest the back of the engine (right next to the bottom oil filler tube), what is that? Nothing was connected to it upon disassembly.






Also, that cheesehead bolt that holds the camshaft pulley on was a real piece of work. Used the right tool, and "woke up the threads" then tried to take it off. Stripped out the bolt. So I got a drill and an extractor. Tried to take it off by hand. Again, no bueno tough as crap. So I figured I impact. Well at full impact for 5 full seconds I was waiting to shear it completely off, but voila it came out. There was some silverish residue on there. My guess was old dried out anti sieze, but glad it came out. Now I have to get the tool off of the bolt.

As for the hole I wondered the same thing ? I assume it was a casting hole that may have had use in other engines/cars This block was used in quite a few cars ....
As for the cam sprocket bolt .... its not uncommon but one must really have a major amount of force pushing in at the same time when turning that bolt
The bolt itself has a stock rough silver finish and if I am not mistaken it is a hardness above 8.8 ... Like 10.9 or 12.9?

It's a casting hole? Where does it go to? Smells like oil in it

Sixline

Uhhh...that's the bottom hole for the AOS(Air Oil Separator/Oil Fill Tube) is it not?

Crazy Eddie

You are correct
I was confusing the hole that the AOS sits in to support it ( on the left of the AOS hole ) The picture Tim posted was a little too much of a close up, I was mistaken
Here is a more distant picture

Crazy Eddie

My word, does that mean you didn't have an AOS there when you got the car ?

PorscheFanatic202

I'll put the aos next to it and see perhaps the support fell off. There were a few things missing when I got it. No external oil cooler, sway bar links. No weener the old owner said this Porsche handles like poop.

Got it delivered to my house in Texas at the time for $3500. Knowing what I do now, I could have gotten it for much less. Absolutely no rust though!

PorscheFanatic202

Got the head off today though. The cylinders don't look quite as shiny as I thought they should. Kind of a dull smooth. No cross hatches. Normal?

Dougs951

No cross hatches on our motors. Shoot some pictures though, the bores should have some shine to them

PorscheFanatic202

Will take some in an hour or two. It also hasn't been run in about 2 months

Sixline

No I was mistaken Ed. He did say this "right-most hole nearest the back of the engine (right next to the bottom oil filler tube)".

No idea what that hole is for. I don't believe it's a support for the AOS.
