: Blown turbo seals?

I was having a little highway the other day and around 6,000rpm's in 4th (open road), the car stopped pulling and the rpm's even dropped a little. I let off thinking nothing of it. Pulled off and checked fluids and fuel pressure and all seemed good..oil pressure was at around 60psi at high rpms. The other day the car started smoking when I hit the gas. I get home and find the oil return line kinked. I just fixed it and was hoping it would solve the issue but no. When I try and boost, the car sputters and barely boosts. Does it take time for any oil that leaked through the seals to fully clear out? Could that cause the turbo to not want to make boost any more. I noticed at idle it sounds almost like the car is missing but not sure. Vaccuum is reading around 12-14psi. All lines seem to be good and tight. Need some help.:(

I know the car was running pig rich when I pulled the plugs the other day. A lot of black. Had them gapped to .028. I don't have the O2 sensor hooked up so I bet that is messing up the car too. I'll check plugs tomorrow. I opened up the intake pipe for the turbo and noticed oil around the compressor wheel.

Just plugged plugs. Two electrodes were blown right off. Plugs were black. Just dropped in a fresh set of BKR7E plugs. I left gap at .035. Car does not smoke so bad anymore and plugs strong. Now just to figure out if the turbo is ok and burning off the oil that leaked through the seals or if its blown.

Any help please. The car smokes under WOT. I noticed the little rubber tube that connects to the nipple by the oil cap was cracked and leaking. Could this be an issue? I noticed my vaccuum is like 10.

Fixed the line off the valve cover. Vaccum is like 15-16 at idle. I checked for oil in the turbo and theres like a sludge near the compressor wheel. Also has a thin dry film of what looks like grease inside the piping.
