This truck sits for long periods between drives as evidence in the low mileage. I recently had the oil changed and there was only about a quart in the crankcase. I have driven it about 500 miles and it has been 10 month since the last oil change. For the last 3 or 4 years it has been smoking badly when first cranked but in 10 minutes or so stops. It sems to have gotten worse. My mechanic says it is probably the rings are worn or split or stuck as a result of sitting for long periods. Please tell me your take on this problem. Thanks so much.

I would be more inclined to think that the valve stem seals are faulty, if rings were at fault it would tend to smoke all the time, and more so no deceleration faulty valve stem seals will allow oil to weep past and sit on valves when started there is a characteristic plume of smoke that dissipates not enough oil will pass during running to notice any excessive smoke, but it will still burn small amounts all the same.
