I have a 1995 cx that only smokes when I make a HARD right turn or going down hills and turning to the right. Could this be a bad valve seal or a cracked head? The engine runs fine. I pulled the spark plugs, and plugs 1,2,3 loked good. Plug #4 is oil deposit fouled after 10XXX miles.??????

 

put in a new seal around the spark plug hole. take off the valve cover and you will see what i mean. i use a little tiny tiny layer of hondabond to keep the seals in place while im setting the cover back on.

 

I'm not getting any oil on the top "ceramic" of the spark plug, just oil deposits on the tip.Do you still recommend replacing the valve cover spark plug seal?

 

oh ok, no. its probably piston rings or a burnt valve or guide. get a compression tester and test the compression, then drip a few drops of oil into the spark plug hole, and check the compression again. if it is higher, then the rings are bad. the oil seals up the piston rings. is there much fuel on the plug? or just oil?

 

It appears to be just burn't oil on the #4 plug. The car had a slight head gasket leak around the #4 cyl. when I bought the car last june. It was leaking from the oil return port into the cooling jacket near cyl. #4. Do you think that this might have "Washed" the cyl. down and wore the rings for this cyl. only?I have since replaced the head gasket. Is it possible that during hard left turns, the oil is "sloshing" up on the cyl. wall of #4 and burning because of worn rings on Cyl. #4? This is the only reason that I can think of, to make it smoke ONLY during hard left turns. The engine has 120,xxx and other than the embarassing smoking, runs good for a stock cx.

 

what color is the smoke? i should have asked that earlier. is it straight white, is it bluish or is it dark grey to black?

 

the smoke is blue. I'm not loosing any coolant, and have no over heating problems whatsoever. I go through about 1 qt. of oil every 200-300 miles.

 

Isn't bluish smoke gas burning?

 

no, gas makes black smoke, water (coolant) makes white, and bluish smoke is oil.
