91 Plymouth Acclaim, Smoke Screen on Start-up
Q: I have a ‘91 Plymouth Acclaim. When I turn it on in the morning, there's a lot of smoke coming out of the tailpipe. Once the engine is warm, it stops smoking. I was told it might be the valve seals. Is this true? If they are, how much would it cost to repair them? Thanks for your help......Arturo

A: Generally if the valve seals are failing you will get a cloud of smoke (blue in color) out the exhaust on start-up. But, this cloud will clear up quickly if it is valve seal related. Note there are some engine designs that this does not hold true. But, I’m comfortable in your case to say that it is not valve seal related. You state that your vehicle’s engine is smoking out the exhaust on start-up and continues to until the engine reaches a certain temperature. I would be inclined to believe that the oil control and/or scraper rings on the pistons are failing. When the piston rings that control oil loss fail, the volume of smoke out the exhaust is from noticeable to quite remarkable as the engine is warming. Once the engine is to operating temperature there may be no detectable smoke what so ever out the exhaust. I would suggest having an engine specialist check into your problem for the needed repairs.
