My 1992 Acura Legend sometimes smokes when its sitting at a light, as the vehicle accelerates, but once the car is cruising, it does not smoke. If left to idle in park, and then reved, it will smoke quite a bit. However, it does NOT smoke at full throttle or while at speed. One may floor the accelerator on the highway and have no smoke. ( confirmed by having another vehicle follow behind) The spark plugs were recently changed for the first time in about 10 years, and despite age degradation, they had nothing wrong with them...to include a lack of oil contamination. Not one had any oil on it. What could be the source of the oil burning? Something other than the rings?

Worn Valve guides are your problem, Most valve guides will have seals on them to keep this problem from happening. Yours have most likely worn and need to be replaced. not sure what the cost would be but expect a shop to charge you 90 an hour for labor. depending on how it is done it will take less then an hour to do it. If the shop has to pull the head to do it, your looking close to 1000 dollars. At our shop when we do this, we put compressed air in to the cylinder, remove the springs and retainers, install the new seals and reinstall the springs and retainers. takes us less then an hour to do it.

99% of those cars leak from the oil pan Exsessively. Aluminum oil pan against a steel block, the gasket takes a beating right out of the factory. You dont see the smoke when your moving because it is going under the car and behind you. Aslo when you are idleing more oil is in the oil pan instead of up higher in the motor. Have a lube facility check the oil pan gasket at your next service or jack it up and check it yourself. I'll bet there's oil all around it..The oil pan can be replaced and a new better gasket installed, but for a price. I believe the engine has to be pulled and the tranny with it..Try running "Lukis oil" in the motor, it may help slow down the leak..about $13.00 for a bottle. It's 1 qt

probably valve guide seals have age hardened. If there isn't a carbon build up on plugs its probably just the exhaust side and oil is burning inside exhaust system instead of cylinder. Piston rings are also probably worn a bit , the pressure of combustion helps them seal,( pushes into cylinder wall tighter) at idle the pressure is less so oil is allowed past them.

Overdrive should not be the priority. Overdrive is basically a function that enables you to regulate even in the adventure that your transmission shifts out of 2nd or third kit. you have a foul seal and a oil stress difficulty. As you force your vehicle over greater beneficial distances, it facilitates the oil to warmth up greater and greater. Heating the oil builds stress, inflicting the leak to start the place the undesirable seal is. the place is the leak coming from below the vehicle?

have you replaced the pcv valve, can also lead to oil consumption.
