Well I thought had cracked my oil problem by redoing the rocker cover but yesterday I had the mid flash up "oil lack" so I checked the oil and fair enough it needed a topup, now I am beginning to think its something else as I checked all round the rocker cover and in the plug wells and there are no signs of any leakage and having looked under the car it all looks to be around the sump, my original thoughts were the rocker cover was leaking at the front and oil was running down behind the Cambelt cover now this seems not to be the case as its still leaking from somewhere.

I even checked the rear crank breather back when I did the rocker cover and there were no signs of seapage from there.

Can anyone suggest anything else that could be causing my problem.

Sump gasket maybe?

Sump gasket maybe?

I seem to remember cleaning around the sump a while back and couldn't see anywhere possible it was seaping from although I think I will have another look as it appears to be coming from that area now.

I have also been toying with the idea of oil pressure switch as I think that is in the same area.

What I dont get though is there is no oil hitting the floor.

If it aint hiting the floor.....

its either burning it ( doubt it as you would have noticed and posted to that effect)

or

Its a mischevious reading from somewhere......

Is it actually physically losing oil ?

Well the sump looks to be coated and the dipstick when I checked indicated below minimum so yeah quite alot imo but where is it all going as the car had an oil change before xmas and its now shows it losing again, think my next option is to get it in the air at the w/e and see if I can source where it is definately loosing from.

You mention burning oil since my scare when it was MOT'd I have kept a close eye and have since then not seen any blue smoke, granted I think I found the source of that problem and have now fixed.
(rocker cover leaking and exhaust manifold wasn't sealed properly so oil was running down the thermostat housing and into the exhaust manifold gasket and seaping into the exhaust).

So now its leaking from somewhere else.

[Markie]

and was it losing oil before previous oil change ?

in the vein of silliness i seem to be inhabiting...   a bit like the odd sock fairy, perhaps there's an oil munching gremlin living in your sump??


or perhaps more sensibly.....   what about the oil pump gasket ?  i'd guess  if it's leaking you'd get nothing on top... but it would coat the sump.....

Mine was recently leaking from the sump plug (it was over-tightened by Vx), difficult to spot because it is being sprayed backwards towards the cross member so not obvious.

Also, are you sure there is no oil in the coolant header tank?... which could obviously point to an oil cooler failure.

But how much are you loosing...? perhaps the engine is burning it - apparently the permissible consumption figure is quite high.. also, have you changed the oil type from what you were using beforehand? (Yeeeepeeee another oil thread us on the way!)

[Markie]

yep, my reason for askingn if it was losing as much before last oil change was that if it wasnt it may well be leaking from the sump since then.

Perhaps the washer wasnt changed on sump  :-/

Unfortunately it was but I thought I had cured the problem by redoing the rocker cover gasket which had been leaking in any case due to the fact I used the wrong sealant. Green Snot now used the black and its fine now fingers crossed.

The oil pump gasket is one thing I had thought of but wasn't sure of the affects of it being faulty, shall be having a good poke about underneath weather permitting at the w/e.

The sump plug was torqued to the recommended haynes setting.

Being that its a 2.0 I'm not sure if it has an oil cooler or if so where it would be, and having checked the header tank its a nice red colour and looking inside it no signs of oil.

How much oil am I loosing well fact that it had a change just before xmas and I made sure it was on maximum its now just below the minimum I think I'm loosing quite abit really. Regards if its burning it I haven't seen any blue smoke come from it since I sorted the manifold and gave the general area a good clean up.

As a rule I tend to stick with VX semi synth haven't put anything else in other than that.

I am beginning to think its something from that area now as originally I thought the rocker cover was leaking as all the lower parts ie ac compressor and pas pump and most stuff around that were/are getting coated, my thinking was the cover was leaking at the front and going down the back of the cambelt cover and spreading but I may have got it totally wrong and should be looking lower down.

The car had a brand new sump plug fitted at its change before the xmas one with new sealing ring so it could be possible not sure how long they last.

best process is often the simple ones......clean the sump and bottom of tank to within an inch of its life. That way you will see if its re-emerging.

Check it daily to see if theres any seeping. Would have thought that it would be quite a lot if your noticing the oil loss from top end ( dipstick)

Presume you dont have any significant oil marks on your drive / road to help you pinpoint the location?

Looking to give it a good clean at the w/e, still I've ruled out its lossing at the top now so shall start with the bottom end now.

Looking to use a couple of cans of carb cleaner or if not soapy water.

Another thing I have thought of is the oil pressure switch? is this in the same place as on the V6 only have seen a thread mentioning a leak from there maybe its worth a look.

Unfortunately no visible oil marks on the road out front where I park its abit of a mystery I i'll get it sorted.
