  Thats the one! Thanks Hereford.

i got me an you guys an update and it's a case of a little good, some not-so-bad and lots of bad news really.

Good news is, no pipes are burning or split or anything. Not-so-bad news is there's precious little oil in the plug wells.  

bad news is, the beast has been drinking coolant and dripping some oil. The oil's coming out from the right side camcover gasket and both burning off by the exhaust and dripping down the engine

Went to a mechanic today and within seconds said " that smell is burning oil........it's coming from the rocker gasket.....there might be steam coming from the front of the engine.......might be water pump, maybe head gasket."

took off filler cap, oodles of mayo. and with engine running, steam too!

visual and verbal verdict.
head gasket gone on right hand side. maybe not on other. waaaah!
excess pressure from water in the cylinders causing oil to force out through newish rocker gasket and bad running (ie not all cylinders starting up straightaway.) i confirmed that it has been a bit lumpy sometimes!

havent had time to price up/investigate head gasket costs but is it even worth it on an 85k 9 year old motor?!

ho hum. best not drive it any more eh?!

Hold on before thinking the head gasket has gone........
So you have a coolant leak... Is the HBV leaking? Is the reservoir cap leaking? Do you have oil in the water reservoir, looks like brown sludge?
Is there steam coming from the front of then engine?  

Is there water in the oil when you pull the dipstick?
Mayo is normal on the Oil Filler cap when the car is doing short journeys.

i'd like to try the selfdiagnostic.. but the oil cooler and hbv were done only last year....

Try the flow chart in the link above a few posts back. Just see what it reckons. Then let u know how you got on with it.

thanks for the link, i'll try reading it in a min. but yeah fyi the hbv was replaced and doesnt look damp again, the cap's sound, there's no oil in the water (like before the oil cooler was done), there is steam coming from the oil cap when it's opened but not sure about any from the front - would that be the water pump? the oil looks maybe ok, maybe slightly thin on the dipstick - its hard to tell as i've had to top it up recently!
i know mayo is normal on short journeys, and i do alot of them! but i got lots of the stuff now and everything else points to the HG.. i think

[dippydave]

gonna get me snifter round the header tank tomorrow and let you know if i smell fumes !!

anyone know how long or how much a HG fix is anyway?!

[SmiffyMan]

I have excactly this problem But lets not forget taht even after repalcing the gaskets and O rings, the chances are that previous owners may have over-tightened the rocker cover bolts and caused them to distort - especially under extreme heat. No matter how methodical you are with torque settings, using genuine gaskets etc.... if the cover is warped you stand no chance. Bloody stupid making them out of plastic anyway!!

[dippydave]

any idea how to check if they're warped?? an how much did it  cost you to sort the hg prob?

[trebor]

Doing the job myself cost me £200 inc new water pump and top radiator hose and a few extra tools.

[ianboyo]

i would check the can covers again might not of seated properly when assembled back together

[dippydave]

ho hum.

well i don't really know what exhaust fumes should smell like in a header tank but both when cold and warm the tank smelled of petrol i think. the mayo on the filler cap and all in the filler pipe is tan coloured. the flow chart isn't working at the moment thanks to ROlex invasion of the site!

i've been suggested best part of a grand for replacing both head gaskets as "it's silly to only do one, and of course the heads need skimming"

hmmm.....  

so..... how do you check that the cam covers are straight.
anybody fancy lending me the tools to butcher fix the problem

or any other advice?

like sell it?!!

I'm no expert but the warped cam cover theory concurs with what my local VX dealer has told me.
My cam cover gaskets were changed  a couple of months ago by the previous owner of my car and the O/S cover still leaks.
I have been quoted circa £330 to replace both covers and gaskets.  
However in the meantime I continue to enjoy the smell of burnt oil for a short time after completing my journey.

I would be very sceptical about reports that the cam covers are warped. Surely metal is more likely to suffer the permanent stretching that would be necessary to cause this.
Much more likely that torque values of cam cover bolts, (8nm), has not been meticulously or consistently observed.

Good point - however the cam covers in question I believe are manufactured from a composite material rather like modern car radiators and other heat resistant parts. The warping ability would be based on the material's threshold of elasticty - i.e. the point from which there is no return. :-/
Anyhoo I agree - they should have used a more suitable material in the first place.
