Hello,
I've just joined this site. Let me tell you about my car and it's symptoms.
I have a 93 Sunbird with a 2.0L (Auto) and of course it's blowing blue smoke and burning the oil like crazy!
I currently put a quart of oil in her every week. I was putting 5w 30 in her and have now changed to 10w 30, but no change in oil burning....I thought maybe the thicker 10 w 30 might stay in her longer.
The only time she really blows blue smoke is occasionally when i accelerate, when it shifts gears it seems to stop. so it kind of only blows the smoke when it's in 1st gear and then stops when it shifts into 2nd.
The valve cover gasket (or head gasket i guess) in her is new, and i have noticed it is wet with oil around the gasket and the hoses for the pcv ( a new pcv valve) around back. I've tightened everything up and even put some of the RTV sealant around the gasket and tightened it down again, but it still is leaking someplace!
I kind of get this "diesel engine" sound occasionally when i'm accelerating. The tappers on the engine are tight, because i checked them when i had the cover off. Nothing looks worn there.
I hope i don't have to replace a valve seal or something, because i would have to basically rip everything apart! and it would throw the engine out of timing and everything!
Any suggestions?
I ran two bottles of Lucas oil treatment through her and later on tried "Bardal no - smoke", but didn't help!
Other than the above mentioned it's a great little car and is excellent on fuel!
Thanks!
Hope somebody can help me, and again sorry if i'm telling the same story 400 other people have!
5w30 and 10w30 are the same thickness at operating temps. They only differ at cold temps. You need to move to something like 10w40 or 20w50 if you want thicker oil at operating temps. Or just put a bottle or two of STP in there...that will tend to thicken things right up. No clue if any of that will actually help any or not. Just remember that those are probably too thick for the winter if it gets cold where you live.
Check compression on all cylinders. Simple procedure of putting a gauge in the spark plug hole, and cranking the engine with the fuel off. Readings will tell you where the problem is. Details included with the gauge.
