Sounds like coolant getting into the combustion chamber. Potential causes in order of significance: Intake manifold gasket (might not have been done right), Head gasket(s), cracked cylinder head, or, cracked engine block. Check the oil. If it looks like chocolate milk it means the coolant and oil are mixing

SOURCE: 95 GMC Jimmy 4.3l W vin rough idle

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

SOURCE: Chevy Prizm or Toyota Corolla 2000 valve cover

The valve cover gasket isn't hard to change. Oil on the plugs indicates a more serious problem. Smoke from the exhaust would be from rings, rich mixture, worn valve guides. It may be that the engine is overfull (that would show on the stick). Oil loss from a leaking gasket would smoke under the hood and leave oil on the engine and the ground.

Will not start


Did you put an entire new distributor on the vehicle or just a cap and rotor? It sounds to me like your ignition is out of time. Make sure all of the plug wires are where they are supposed to be on the cap AND connected to the correct spark plug.

Oil leak on driveway coming from front of engine


Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    My car does not keep oil in it. About every few days i'm having to add oil because it starts ticking, what would cause this? Also, what would cause white smoke to come from my tailpipe?


    oil leaks could be coming from a few spots ,valve cover gasket ,oil pan gasket and a bad harmonica balancer seal ,and the white smoke coming out your tail pipe is a sign of a blown head gasket ,check your dip stick and if the oil is creamy is your head gasket

    How to fix a front leaky oil seal in a 1995 Toyota Camry LE


    Three seals to check. easiest is the valve cover seal. Number and remove the 4 wires going into your spark plugs. remove 4 nuts holding the cover and replace seal.
    Next easiest is the distributor O-ring. Remove air filter assembly remove the distributor cap, then the distributor. With the valve cover still off, loosen the 2 bolts that clamp the distributor down. Remove the 2 terminal leads going into the distributor (4 wire terminal/2 wire terminal) Mark the case of the distributor and the case of the head with one line so you can line it back up on reinstallation. remove the 3 bolts holding the distributor down. Replace O-ring. replace distributor, align, tighten the 2 bolts, then tighten the 3 bolts. replace terminal wiring and cap. replace air filter assembly. Replace valve cover with new gasket. Place spark plug wires back into their proper places. The last one is the oil pan gasket. Drain all oil and remove all blots holding the pan. drop the pan and replace the gasket. Put it all back into place. Do not over tighten the pan bolts as this will cause the gasket to deform, making it leak again.

    Valve cover gaskets, now it wont run


    You need to get the timing checked, did you mark the position of the distributor before you took it off. If not you might be slightly off with the new distrib.

    Oil Leak


    Take the car to a car wash and power wash the engine. Do this ONLY with a cold engine. And be prepared to have problems with it starting as water get's into the electrical components. Take some WD-40 with you to spray inside distributor caps, on spark wiring, etc. to get the engine running again.

    Then check the engine weekly to see where the oil is coming from.
