SOURCE: Leaks oil looks like from valve cover

You have to remove the spark plugs cables and remove the four nuts that you see when the cables are removed.

When the four nuts are removed, simply raise the valuve cover. When replacing the gasket, make sure you get the gromets as well. Those sometimes get worn or crack since they are more exposed than the value cover gasket. Make sure that you clean the cover from oil and replace the gasket with no use of silicon.

Good Luck.

SOURCE: OIl leak in 2001 Grand Cherokee Laredo

valve cover gasket is like $20 and a do it yourself job, just buy a manual like a chiltons from an auto parts store. if it was valve cover, the smoke would be coming from engine, not tailpipe.

rear seal is in between engine and tranny, this would cause oil to leak on ground, but not to burn

if smoke is coming from tailpipe, your piston rings might be going bad. that is an expensive repair, but switching to synthetic oil may give you several more years of life out of the piston rings, synthetic oil has a way of soaking into bad piston rings and temporarily making them like new again, unless they are already too far gone.

SOURCE: replace valve cover gasket

I have the same problem on a 2003 Town & Country. The cover for the front 3 cylinders is quite straight forward, but in order to do the rear cylinders I believe you are going to have to remove the cowling below the windshield. You will need a gear puller to remover the windshield wipers first, then remove the cowling. Than should give you more room to work. It's still not going to be easy, but it sure beats paying hundreds of $$$$ in labor charges.

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.

    Oil leak


    You have to differentiate whether the oil leak is from the engine or the tranny. After determining where the source, you must isolate the specific area; timing belt area, the middle-between the engine and the tranny. This can be cheaply determine by placing white piece of paper underneath the engine and observe the droppings of oil. Oil leak repair can be costly-especially an oil starved engine, so isolating the source is essential and tear-down might required.
    Due to the age of the vehicle, possible sources are the camshaft seal, crankshalf seal, oil pan gasket, crankshaft end seal,distributor o-ring, and valve cover gasket.
    In addition, other oil leaks can come the transmission, and power steering pump and rack'n'pinion. Best to raise the vehicle and inspect undercarriage of vehicle.

    I have oil leaking from either the timing chain or the front main


    if the front seal leak you can just replace the seal, if the timing cover is leaking then you will have to remove the cover. while you are in there, I suggest that you go ahead to replace the timing chain ( timing set ), seal and a new cover. parts cost less than 100 dollars.

    Toyota Camey oil leaks around timing chain cover


    addatives don't fix the problem. They only make the problem a bigger deal when they stop masking the problem. You have a main seal leak. if you don't know what that is go get it fixed. It is not a simple fix.
