I'm having a problem with my W reg Asta, somehow petrol is getting into the oil. Any mechanicaly minded people got an idea of the cause & cost to repair?

Anybody know a good mobile mechanic? My Motor is broken too.
I'd say it sounds like either the fuel pressure regulator or fuel pumps had it or even worse a cracked piston ring.

You sure its petrol getting in and not water? Does the oil look like mayonnaise? If it does it sounds like the headgasket has gone.

Definitly petrol you can smell it on the dipstick
If you have petrol in the oil you've got huge problems, have to ask what made you sniff your dipstick to start with?

I noticed the oil on the dipstick looked particularly runny and realised that as it wasnt water( hadn't gone creamy ) the only other thing it could be was petrol. Hence the sniffing.

Thanks, how would I find out which it is?
What other symptoms do you have? Engine oil usually has a kind of petrol/engine whiff to it anyway. Just because oil is runny and not Mayo (yet) doesnt mean it's not head gasket failure.

It sounds like the fuel pump is leaking petrol into the engine, as long as the fuel pump is mechanically driven, on the side of the engine block or cylinder head. Replace the pump if so, and change the oil (and filter while you're at it), as it has been thinned out with the addition of the petrol....

not just a petrol whiff to it, it stinks of petrol.

Come on!
A compression test will tell you. Should only cost a few quid in any garage.

what engine is it? as the only petrol vauxhall with the fuel pump on the side of the head is a 2.2, other than that, there all 'in tank pumps' its very unlikely for fuel to be able to get into the oil, even if a piston ring was knackered its still highly unlikely it would let enough fuel into the oil for it to change that much, i work for a main dealer vauxhall garage 
so fire any questions my way

It's a W, but don't know if it's the prefix or suffix W. If it's the former it makes it a 1999, and the latter would be a 1980, meaning it would have a mechanical pump, shirley?

I worked on them, and left the trade in '87. If it is an '80, it wants crushing anyway
Which end if the reg is the w?
If it's xxx 123w it's 1980
If it's wxxx 123 it's 1999
If it's xxx 123w it's 1980
If it's wxxx 123 it's 1999
