rear oil seal exquisite workmanship
Run the engine when you check for oil leakage from the rocker or cam cover, so that the moving parts beneath it are spraying oil around the inside. Keep clothes and hair well clear of the pulley(s) and belt(s).rear oil seal exquisite workmanship.
Look carefully for oil seeping out from around the gasket flange, particularly at the front and rear ends of the cover where the gasket may not be sealing properly.
Leaks may be due either to the cover screws being unevenly or excessively tightened, or to the gasket being broken or distorted.

Some gaskets are held in place on the cover flange by small tongues. Others may be stuck to the cover, or just held in position by the cover flange.
A broken gasket should be replaced. A distorted gasket can usually be sealed temporarily, but a new one should be fitted as soon as possible.
Slacken the cover screws and straighten the gasket with tweezers or thin-nosed pliers. Retighten the cover screws and check again for oil leakage.
The screws should be tightened just enough to press the cover on to the gasket firmly, but no more. Overtightening distorts both the cover and the gasket, causing more leaks.

Leaks may also occur around a cover which is secured by nuts and bolts, if the washers are wrongly fitted or the nuts not tight enough.
On some engines, special fibre or plastic washers are used. Make sure that you fit washers of the same type, and that the screws are correctly tightened.Inspecting the sump.rear oil seal exquisite workmanship
To check the sump pan thoroughly, run the car up on ramps so that you can get underneath the engine end. Apply the handbrake and chock the wheels still on the ground.
With the engine running, check for oil leaks around the outside of the sump-pan mounting gasket flange, and also from the drain plug at the bottom of the pan.
An engine-mounted mechanical fuel pump may leak where it is mounted on the block.
Look closely at the sump mounting flange around the crankshaft: sometimes the gasket is in several parts, or there are separate gaskets at the front and rear, which are liable to distortion. Leaks here can be confused with those from a crankshaft front or rear oil seal.
If the sump gasket is leaking, it may be only because it has settled and contracted slightly in service. The leak may be stopped by tightening the sump mounting bolts or nuts.
Make sure you tighten all the fixings evenly, working gradually around the mounting flange.
Beware of overtightening, which can distort or destroy the gasket. If tightening fails, the sump gasket should be replaced.
An occasional oil drip from the sump drain plug shows that the plug is not tightened enough, that the washer is leaking, or that the plug is not fitted correctly.

If there is a steady drip from the plug, fit a new washer. Otherwise, the washer should be replaced at the next oil change (See How to drain engine oil and remove filter).
