So I was going through my tc doing regular stuff getting ready to turbo it and I noticed oil on the thread of my spark plugs. What is causing this tc is bone stock right now.

 

Please dont tell me a head gasket, car has 84xxx

 

It's not the head gasket, the only thing I know will do that is the valve cover gasket. It's an easy fix. If it was the head gasket or the piston rings, it would be smoking and probably see more oil. Goodluck, hopefully you can get it fixed

 

If you do change the VC gasket, make sure you get the torque specs from scion and use a star pattern to tighten the bolts back down. If you mess that up, you'll end up doing it all over again.

 

Could it be antiseize? Our cars have an all aluminum head

 

Nope

 

What do you mean antisieze? And I have another problem it sounds like really loud gear whine at 2000-3000 rpms then it goes away. Any ideas?

 

if its engine oil its most likely coming from the manifold gasket, check it to make sure its line up properly. I accidently had a piece of my gasket not tucked into its grove, well i drove like that for 5 min before the smoke started pluming. to say the least my whole engine bay was covered in oil lol

gear wind noise can be rasp coming from the exhaust, prolly needs new resonator.

 

How could gear whine be rasp from the resonator?

Have you ever changed your trans fluid?

 

Also, if you turbo an 84k mi car without making sure the Drivetrain is in perfect shape, expect problems.

 

Thats why im going through and checking everything, I dont know if the transfluid has been changed i picked the car up at 79000 I have not personally dont it.

 

resonator in perfect shape, car came from florida so zero rust on any part of the car and the exhaust is solid went through and checked it.

 

Now would be a good time to replace the timing chain & check compression.

 

And if the resonator was bad wouldn't I hear it at any rpm?

 

the timing chain doesnt need to be changed at all. it doesnt have a service interval. i have never seen one go or stretch, im not saying that itll never happen but its not likely.

 

I didn't think the timing chain needed to be changed either that's why I kinda ignored that statement.

 

have you looked at the friggin VC gasket yet. im willing to bet thats your problem

 

Yeah it didn't look like it was that bad I am putting it back together tomorrow

 

did you get a new one? i dont think you can reuse that gasket

 

Yes bought a new gasket would never reuse an old one.
