If this is a 5.0L engine the Oil leak is probably this intake gaskets,I would reccomd you replace the PCV filter and gromet at the same time the gaskets are replace and it would be a good idea to replace the PCV valve also.It would be a smart idea to have a professional to replace the Intake Gaskets!!!!!!!

SOURCE: oil leaking out of valve cover gasket

It is a Valve Cover Gasket. You can get a new one at any Auto Parts Store. To make this repair last longer, Do not get the Cheap one, Get a Felpro Gasket and it will Quadrupel the Gasket Life. Please Rate My Response! Thanks!

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 on manifold passenger side - v6 4motion

Get a can of Gunk and clean the engine according to the directions there (please do read them), with attention to the area around where the oil leak is.  Once you get the motor squeaky clean, you will be able to trace back to where the oil is coming from.  It may be running down the underside of a hose so you will need to look carefully.  You can do all this in the driveway.  You will probably have to let the engine get to operating temp before it will start leaking.

SOURCE: leaking valve cover gaskets

The problem is over tightening.

If you over tighten your fastners you will sqeeze your gaskets too much and they WILL leak.

You can use black silicon sealant LIGHTLY but you don't really need it. If you have the V6...the torque on them nuts are only 80 in lbs each

SOURCE: I had the valve cover gasket changed on my 1996

on a v6 ? Low on oil? rear cam plugs leaking? The lifters are on the end of the rocker arms and may get clogged. I have had some luck running 0w30 mobil synthetic for about a week or so with a new oil filter [Not a fram filter] and after that put 10w30 synthetic oil back in and a new filter. Check for oil leaking at other locations. If the noise is at the front of engine near water pump it may be the hydraulic timing belt tensioner.

I had my val cover gasket replace. my honda 1999 crv is still leaking oil. where could th leak be coming from


What makes you think the valve cover was leaking,was oil coming from there.Exactly where is it leaking from.If the oil filter is tighten too tight,then it will leak,also by the oil filter is the oil pressure switch,it's screwed into block,it can leak.The rear oil seal can leak,where engine and transmission meet.If valve cover is not installed correctly,it will leak and loose compression.

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.

    Seems like air is seeping in but also leaking oil on the headers could this be cause of the gasket on the valve covers


    Yes, a bad gasket would be the cause of the oil leaking out, but has nothing to do with any air getting in. There is no vacuum under the valve cover. Change the valve cover gasket and check the intake manifold and the vacuum hoses coming from it for vacuum leaks (air getting sucked in).

    Smoke comin from top rocker cover smell like burnin oil


    Could the smoke be coming from the exhaust manifold on the passenger side of the engine? When the valve cover starts to leak, it is common for the oil to leak down and burn on the outside of the exhaust manifold.
    Replacing a valve cover gasket is not difficult or expensive, and it is common for BMW valve cover gaskets to get brittle and shrink and start leaking every 10 years or so. My wife's 330 needed a new valve cover gasket at 6 years.

    Oil leaking from under the front of the motor. Have had both manifold gaskets changed, yet still have a leak. Now the starter is full of oil and I have to replace it


    the manifold gaskets role in an oil leak? oil under the car i would be thinking about a front or rear crankshaft seal or the oil pan, or the oil pressure sender unit. if there is oil on the sides of the engine i would look to the valve cover gaskets.

    What would cause oil in coolant and leak near intake manifold?


    Head gasket, if you have a V6 or a V8, can't tell which one is at fault, so both will might as well be changed.
    If the leak near the maifold is oil, the valve cover gaskets are leaking.
    When head gaskets are changed, all the necessary gaskets come in the gasket kit.
