Oil on Spark Plug Threads - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Tylerscully · 05-11-2018, 02:02 AM

I have a 2010 Chevy Camaro SS with 21k miles and have been running with a k&n intake, Kooks Headers with no tune for about a year. My friend in his 1998 Trans am with 55k miles has been running with the same mods as me and also has been running without a tune for about a year and he realized 2 of his spark plugs had oil on the threads so i decided to check mine too. I have the same thing but on more then 2 spark plugs. Thoughts? WHAT SHOULD I DOOOO.
The things ive learned about this is that it could either be the valve cover gasket leaking (it does not) valve seals (doubt it) piston rings (also doubt it) and i was also thinking about maybe increased oil going through the pcv causing it to leak past the valve into the threads? IDK alot about cars but i dont wanna fix a motor lol.

See this post https://www.camaro5.com/forums/showt...highlight=seal

Could be the plugs where removed during the hdr install and the seals weren’t seated correctly when put back in. Wouldn’t hurt to put in new plugs and torqued to spec.

Agree.. new plugs and torque to 11 ft lbs. I’ve always use the manuals torque specs to be safe...
