Hi, i have just bought a 2.5v6 omega with an oil leek off a mate of mine. The car runs fine with no problems apart from the 5 ltrs of oil a week it needs. My mate took it to a garage who said it was the head gasket. I'm not totaly convinced that it is that and was wondering if anybody knew of any "common" problems with oil leaks before i strip the head. It appears to be leaking from the left hand side of the engine as there are deposits of oil all over drivers front wheel and none on passengers.  i just dont want to spend the time stripping it down to find out that it could have been fixed easiler and quicker. any help on this matter would be most grateful
Regards

put more detalis on your profil is easier for help, and also you sure is not cam covers leak?

5 ltrs!...that must be pouring out somewhere and should be quite noticable with the engine running.  I would have the car up on ramps / stands and inspect thoroughly to find leak(s).

[thomascdx24v]

I have had it up on ramps and there is no obvious leak. It is pouring out everywhere and had attacked the alternater aswell. everything is caked in oil and isnt very pleasant when stopped at traffic lights and smoke is pouring out of the bonnet. ive checked the filler cap and no signs of water in oil so could it be head gasket?

[FRE07962128]

Others on this site more skilled with Omega's will no doubt shortly be giving you quality advice, but one thing's for sure do not use the car with so much oil flowing around.

Risk of fire is very great,especially with the alternator getting covered, let alone massive damage to components and the engine itself.  The plugs to start with must be getting absolutely soaked and are in real danger of failure! In addition the heavy loss of oil could starve vital moving parts i.e. pistons of adequate oil / pressure and cause catostrophic failure.  

If it is the head gasket oil should be visable coming away from that side of the engine.

Driver's side cam cover? You'll need to clean the engine, but not steam or pressure, it should then be easier to see where it's leaking.

[mike213735]

Surely, if the plugs / leads are drowning in oil, doesn't that point to the age old Omega fault, Cam Cover Gaskets?

Thanks
Mike

There is no visable sign of oil coming from the head gasket. the engine doesnt seem to be burning oil just leaking the stuff

[Kevin Wood]

Is there any oil in the plug wells? Sure sign of cam cover gaskets if so.

Also, check the pipes that run up to the oil cooler in the valley of the engine, from down by the oil filter.

If this is the case Thomas then it still must be 'flowing' from somewhere...ie as others have suggested cam cover gaskets :-/


To repeat 5 ltrs of oil leaking over just one week must be visable from a particular location on the engine if it is not burning oil as you state. :-?

Cam Cover

[hotel21]

Clean all the oil deposits from the engine as a first step as only then will you really be able to source down the leak.

If its a true 5 litres per week, it should be easy to spot!

I would strongly suggest the cam cover gasket.  Check the howtoo area and there is a step by step method on how to do it.

Its doubtfull in the extreme if it is the head gasket at fault.  If it were burning 5 litres per week the car would leave a smokescreen behind it of a sufficient size to hide a small destroyer fleet....

[HGV mechanic]

if you can get ur hands on a steam cleaner then do so, or a presure washer is the next best thing, give it a good wash, being careful of the ignition side of things i.e dis pack, then let it tick over and watch for leaks, as others have sugested look around the side and vally of the block - (oil cooler pipes)
pull a HT lead out  and look in wells-(cam cover)
and check around the front and back of block -(crank seals)

best of luck

at least you dont have to worry about rust
