Cam sensor oil leak??
 

I have some oil coming out of the head on my 1990 turbo supra. I have called around and the cheapest I can fin the sensor for is like 500 bucks?? Do I need to replace the actual sensor or is there a seal in there that just needs to be replaced?? And I cant find a cover for the cam sensor either. Any places I could go to source a cover?? I can get pics later on if anybody needs them to help me. Smoke comes out from under the hood sometimes and makes a otherwise really nice car look like a pile.

Its common for the O-ring to go hard and leak oil onto the exhaust heat shield, not an expensive item and not that difficult to replace. Apart from Toyota your best option is a scrap yard for the cover. You`ll find these useful Link & Link
