It's official, the car is cursed.

as much as i think the restrictor might help i always thought that once the seals were compromised in anything that they were prone to leak again
but maybe with the restrictor it wont be as bad?

It's been awhile now but it probably took me 6 hours to take the turbo off the first time. Nothing magical about it, just lots of fasteners and no room to work. Patience highly required.
You are perfectly capable of doing it but the bottom line is that you'll lose a day in the process, both ways. Even with help. Not trying to scare you off, just setting a realistic expectation...

Yeah, I definitely don't have that kinda time. I'm going to flat bed it to the shop tonight. Going to see if there's an oil restrictor in the feed line now. If so, turbo gets pulled and sent for rebuild. If not, one will be installed and we'll see what happens...

Reading this thread, I was wondering: none of this really explains the loss of power that was experienced.
Unless, somehow, the bad turbo with it's oil issues needs alot more exhaust gas energy to spin properly.

A couple of comments – some on some really old stuff!
The intercooler pipes popping off is very common – the problem is the angular force on the pipe right after the compressor output – it is trying to force the pipe off. The best fix is to attach a physical restraint to keep the hard pipe from being pushed out. The factory hard pipe is restrained by the stock air box (see- Porsche wasn’t stupid!) – most aftermarket pipes do not have any restraints.
For track cars I usually add a small tab with a hole so I can add an attachment point and restrain the pipes movement. I usually tie the pipe to the engine lifting point with either a turn buckle or just a simple cable tie.
Once you get a little oil residue on the hose coupler you will have a hell of a time trying to get the clamp tight enough to hold without the restraint.
Note#2 – you are missing an oil pan heat shield near the header to crossover flange – you will regret this later…
Note #3 – plugs look great, no sign of a major external leak, no oil pooling in the intercooler pipes….leaves only an internal hotside turbo leak.

Chris, got a part # for that oil pan heat shield? I'll go out and get one to install.
Yep, that's kinda of what I thought about the oil leaks. Plugs look great, no motor issue.
Flatbed picked up the car last night, it's at the shop now. Going to pull the intake and check to see if there's a restrictor in the oil feed line. If there is, turbo will be pulled and sent away for rebuild. If there isn't, one will be installed and we'll see what happens...

Its the oil pan gasket heat shield for the passengers side of the block - that should be enough of a description for Lart!
The best one has the oil level pick up shield as well…

Found this restrictor in the turbo oil feed. It's green and it measures 0.045". There's no restrictor in the actual oil feed line. Is this restrictor part of the turbo and not something seperate? In other words, is it supposed to be there and I need to add an additional restrictor in the actual oil feed line?

Doc, did you call John at Vitesse to confirm if that is the restrictor? I have never seen a restrictor like that so for me I would have to call John and confirm, since the ones I'm used to see are attached to the line.
