Exhaust Head Smoke

7mlove88 · 06-29-2009, 12:14 AM

I have an 88 turbo supra with 180,000 miles. the head gasket was replaced and the engine was rebuilt 20k miles ago and the car runs just fine..but lately I noticed smoke coming from the exhaust manifold as soon as i turn the engine off..I think it might just be a bad gasket but I'm not sure..any ideas??? thx!

Good news! It’s probably the O-ring in the cam-positing sensor needs replacing; check the front of exhaust manifold heat shield for any burnt oil residue.

I just checked that out and the O-ring on the CPS is not damaged and looks fine..but the plastic cover of the CPS and the plastic gasket within is cracked and completely destroyed...so despite the 0-ring retaining the oil within the sensor could that plastic cover & gasket be the problem?

yeah you probably have to replace the gasket. And check the hoses if theirs any split it'll need replacing, I've had to replace numerous ones.

So i replaced the cover and the gasket and when I replaced everything the car would not start..turns out I forgot to mark the position of the CPS..would it be alright to just rea-align the holes from the Dowel pin?
