Well I havn't gotten a clear answer from some members, but my S/R was running just fine, then I decided to check the sparkplugs (no problem, just looking) and I saw oil... all in the sparkplugs tunnels... then I took out the 1st and 3rd(from left to right) because the 2nd and 4th are cross threaded I think... someone said bad piston rings... I found some for cheap
So is it piston rings? and was it bad that I pulled them out? and now it pours white smoke... please help
valve cover gasket for the oil around the plugs. Wwhite smoke usually indicates head gasket, if it was oil burning off the smoke should be black. Does the smoke smell sweet? If so it's deffinetly your head gasket
So it could be just gaskets? I was driving it just fine, so maybe not piston rings?
well unless there is an oil consumtion issue or alot of oil on the tips of the plug (blow-by) than I wouldn't be to concerned about your rings
I think the tips were clean(til I pulled them through the puddle of course) and not a big consumption
So I should try valve cover gasket then headgasket? and if nothing else, rings haha
oh and new plugs of course. lol
Posted via Mobile Device Thanks everyone! Yea, how would I get the the other two plugs out? Theyre like cross threaded and stuck
Umm... turn really hard, if you dont have a breaker-bar, then put a piece of pipe on the end... also if it really IS crossthreaded... do you know how to do a Helicore job? or you may need to replace the entire head if it is that bad.
I am saying that because if it is crossed, then there is a chance that the plugs could be blown out of the engine under compression, and at that point you need to do the head anyways... and you may have a nice size hole in your hood. (this happened to my Sable and it was not pretty)
The oil is just the valve cover gasket, replace it. If you have cross threaded sparkplugs that is a different issue. I would bet because of the length of the sparkplug that they are galled or slightly stripped but not cross threaded. You should be able to just chase the threads with a suitable tap and save them. This was probably caused by someone removing the plugs from a hot engine. A bit of antisieze on the plug threads when installing would prevent this problem. None of this has anything to do with head gaskets or rings. Good luck!
thank you! So what about the white smoke? That happened because the oil drained down the sparkplug hole. Thanks for everything. I'm at my girlfriends apartment rightnow, and a supra is next to me. First supra I've seen in person. Very clean. Twin Turbo ;/
well if the white smoke comes out non stop it is water(meaning bad head gasket) if it is more of blue-ish then it is oil it should stop ( did some of the oil go on the piston?) if not then well. then yea it might be piston rings.

soon to become mtx!! and i was away for a long time because i am trying to finish my vw's
Its probably oil. Considering I never had any type of problems(smoke,oil consumption, or anything) til I pulled the plug. Which means the oil went to the piston. So If Valve cover gasket doesnt work, then i replace headgasket
Did you let the oil that was puddled around the plugs into the engine when you removed the plugs? If so it will take 10 or 20 miles of driving to burn it out of the exhaust system. Oil can damage the catalytic converter & o2 sensors if there is too much of it. I really don't think it is a problem with the rings or head gasket. You should also consider installing some new Motorcraft plug wires as the oil probably saturated them.
