View Full Version : 2.8 question NEED HELP

My 89 cavalier z24 just developed a problem, missing and blowing whitish smoke. I pulled the plugs and 4 of them are covered in dark liquid and smell heavy of unburnt fuel. I just did a tune-up last month with plugs, wires, coils, and fuel filter. the wet plugs are three in the rear and the right front. The other ones are perfect. ANY IDEAS are appreciated.

...blowing whitish smoke...
Burning engine coolant ?

& that would NOT be good.

Head gasket..
+1 Check the oil... look for a whitish milky residue under the oil cap or on the dipstick, this is indicative of coolant in the oil, and probably a head or intake gasket has failed. Its odd that 2 plugs are ok, but 4 are bad.

i know it doesnt make any sense on both sides, im leaning toward the LIM, my grand am lost it twice, and its less expensive. Besides a compression test what are some easy ways to see if the head gasket has failed, the oil is fresh, but possibly burning it.
