Burning a ridiculous amount of oil

ringo110879

Hi all, so glad i've found this site.

I have had my 2001 2.2 SRI 150 Vectra for 6 months. It had been using loads of oil since i bought it, a good 1-2 litres every 300 miles. It smokes a little on start up which Isounds like it could be the piston rings. When driving it doesn't seem to smoke an awful lot until i rev over 3500rpm, then it fills my rear view mirror like the batmobile!! Should i look at gettin the piston rings replaced, and is this gonna be an expensive job? Thanks

P.S The engine management light is on, vauxhall diaganosed this as a cat fault (below threshold). Does this mean I should replace the cat now, or would it better to sort the oil leak first.

Thanks for any help

Sounds like it may be the stem valve seals as well as the piston.

It can be a pritty expensive job it all depends on where you take it.

It could be the cat or the lambda sensor. If you are going to sort out the oil leak i would do that first.

Have you had the chain changed if not i would do this while you are doing the oil leak.

Hope this helps.

cold starts are usually the stem seals if you dont get any knocking

under load is usually the rings

do a compression test

you got no oil leaks from the chain area ? - look under car nxt to drivers front wheel

i would say if your going to do the rings, stem seals and chains and tensioner, it would be cheaper and quicker to drop a recon engine in, but make sure its not got the old type oil feed for the chains!!

sounds like the rings 🙁

I have exactly the same problem, i have recently done the chain and valves due to the tensioner failing, anyway put it all back together runs lovely but it is using over half a gallon a week!!! car does 3-400miles in that week, no signs of leaking oil, and no excessive smoke coming out of exhaust, where the hell is it going?????
