Make sure that the cover is not twisted or warped and that there are no high spots of nicks or cracks on the crankcase. Lay the cover on a flat smooth surface, like a sheet of glass or granite work surface and look for light due to gaps between the cover and the surface. If there are any high spots or if there is any distortion in the cover, it will have to be lapped out on a very flat surface plate or machined out on a lathe etc. When using a sealant, especially a silicone based one and there is a persistent leak, apply a liberal coating to the surfaces to be sealed and tighten the screws evenly until they are all about 4 turns from tight. Leave the joint overnight and tighten the screws the next day when the sealant has had time to harden and form its own gasket.

1978 GL 1000 left head leaking oil

Hi, Paul external oil deposits fall into 3 categories:
1. WEEPAGE is oil that is sweated pass gaskets, seals, o-rings, and crankcase seams, it's covered by dry dust and is normal for older engines with lots of miles, no repair is necessary.
2. SEEPAGE is the same as weepage except the deposit is wet and confines itself to a specific area, repair is optional depending on the owner's cleanliness criteria, the deposit location and the weight of his bag of "DRACHMA"
3. LEAKAGE is the same as seepage except it is enough to drop to the ground leaving a spot. Repair as necessary.
To find the source of your oil leak, start at the point where you see oil and trace its path going up and forward, blowing baby powder from the palm of your hand will help in those difficult to see areas if there is too much oil present then buy a spray can of engine degreaser apply it to the affected area then rinse off with a pressure wand or garden hose, use compressed air to blow off excess water or just let it drip dry, take your bike for a 15 minute ride and check for the leak.

I will try and simplify the problem. I have an oil leak, which I traced up the back of the engine to the cylinder head area.
When I removed the top plastic cover on top of the coil packs I found oil in every recess next to the coil packs. The crankcase breather pipe was also off. The source of the leak is not evident, but it is definetely above the cylinder head gasket area.

1998 lexus gs 300 oil leaking from timing belt area

style engines have timing chain covers that are sealed to the engine block using a gasket. With time this gasket can become weak allowing engine oil to leak. If after inspection this is the case with your engine, the only remedy is to disassemble and remove the timing chain cover to replace the gasket.
Top should read Timing chain style engines. hope this infor will be of use

I have a 1999 Mitsubishi Galant and need to know how to put on a valve cover gasket. Oil is leaking out and dripping and it's causing it to burn and smoke comes out of the car.

    • 1 Allow the car to cool. Disconnect the battery terminal. Remove the right side vent screen top extension. Disconnect the ignition coil with power transistor and its wiring and brackets.
    • 2 Disconnect the left hand side coil wires and spark plug wires. Remove the spark plug wires, valve cover bolts and the valve cover. Unplug the electrical connections from the intake manifold runner control actuator. Unfasten the actuator retaining the screws, right bank heated oxygen sensor front and rear.
    • 3 Remove the heated positive crankcase ventilation (PCV) valve. Remove the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor. Disconnect the ignition coil with power transistor and its wiring and bracket. Remove the valve cover bolts, the valve cover and the old valve cover gasket. Clean the valve cover seating area with automotive engine cleaner and place the new gasket in the gasket seating area.
    • 4 Replace the parts that were removed and disconnected by reversing the steps. Replace the valve cover gasket and tighten the bolts, in sequence, ensuring not to over tighten. Put back the ignition coil with power transistor and its wiring and bracket, the heated positive crankcase ventilation (PCV) valve, the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor.
    • 5 Add oil to the car. Start the car and let it run at idle for a while to check for leaks..

1997 Honda Accord, 4 Cl. Replaced valve cover gasket, oil still leaking somewhere directly below the valve cover?

Sounds to me like you have either forgot to put back on the breather tube that runs off of the top of the valve cover, or, you did not set your valve cover correctly, or the torque is not correct on the cover itself.
8.7ft/lbs and the torque sequence is inside to outside (torque the inner-most nut between cyl 2 & 3 first, then the one above it then alternate sides on the outside ones). Recommended Hondabond is on the corners and the cam cap areas.

I have a craftsman lawnmower with a 24 horse intek motor with the 4 screws holding air filter. it has started leaking oil at base of the left jug. it is leaking right at the bottom of it so i cant see...

I am assuming you are calling the cylinder the jug on the engine. If you think the engine is leaking oil from the cylinder you have to replace the crankcase. The cylinder does not separate form the crankcase as they do on atvs. If you see the leak at a gasket, it could be a blown head gasket, valve cover gasket or a sump gasket. The sump gasket is the gasket between the crankcase and the sump. The sump is the part of the engine the mounting screws thread into. The valve cover gasket is between the head and the stamped steel cover. Replacing the valve cover gasket is easy. Just remove the four bolts to remove the cover. Then clean the old gasket off. You can apply a thin layer of rtv to help seal the valve cover. The head gasket is between the cylinder and the head of the engine. If this gasket fails, the engine can burn oil and/or leak oil. The head gasket is more involved to replace. You need a set of feeler gauges and a toque wrench to do the repair

Oil smell smells like it is burning oil last oil change was 3 months ago

Common causes of smelling "burning" oil are:
  1. a leak in the valve cover gasket. When oil leaks from the valve cover gasket, it will often burn off on the manifold.
  2. a blown oil seal causing oil to burn off on the exhaust system
  3. check your exhaust for "blue smoke" a sign that the engine is actually burning oil. Just guessing here but a 16 year old Volvo is bound to have quite a few miles on it.
I hope you found this post helpful in diagnosing your problem. Thank you for using Fixya! Greg

There's an oil leaking to spark plug

Change your valve cover gasket. If your Honda model only uses Gasket sealer , Take the cover off and reseal it with Hondabond 4.

Brake rotors and pads recently replaced. Seem to

You could stop the noisy brake problem by applying special adhesive to the back of the brake pads. They are available at the autoparts stores.If you buy high quality brake pads, you would see the anti-noise shims included in the package.

As for the oil dripping issue: have the required quantity of oil in the crankcase-3.2 quarts to start when you change engine oil. Inspect the oil-pan gasket, drain-plug, oil-pump seal

Oil leaking way to much

It is a leaking valve cover gasket (easy fix) or the gasket between the head and crankcase ( most likely but much harder to replace). Check the valve cover gasket first.
