Turbo oil leak?

Dave 5 May 2005 02:51:32
 Hi,

I have an Astra coupe Turbo (2001) and have developed an oil burning smell
through the air vents. Vauxhall have charged me to replace a turbo gasket
which didn't cure the problem, so they now insist there is an internal oil
leak and suggest I replace the turbo (£1100!!).

I find it hard to beleive that an internal leak would cause a smell at the
front of the car, I would expect the oil to come out of the exhaust...??
They insist all pipes are fine.

I would greatly appreciate any advice anyone could offer regarding this or
any steps I could take to see if they are right.

Any ideas?

Many thanks,

Dave

Are you sure it is not a smelly heater fan speed resistor? Or leaking
antifreeze?

some Vauxhalls have a filter inside the top engine cover, which, if blocked,
causes fumes to eject elsewhere.

Otherwise a leaking or blocked pipe or gasket may be the answer.

You're right. An internal leak usually shows up by a noticeably smoky
exhaust.
And I can't see how an internal oil leak, could result in a smell of burning
oil through the air vents. There's no direct connection between the oil and
ventilation system.

How does the car run. Does the turbo appear to be working as normal?
Is there any excessive smoke? particularly when you accelerate after
decelerating for a short time?

If the answer is yes to the first question, and no to the second, I would
guess your turbo is OK.
And if the turbo does need replacing, I'd take it somewhere else.
£1100 sounds like a ridiculous price for a new turbo inc fitting.
I don't know about Astra turbos, but most std turbos are around £250-400 at
most, in which case over 700 quid to fit it seems an awful lot of money.
Any ideas?

Yes. Take it somewhere else, or even have a mobile tune-up guy have a look
at it.
The least he can probably do, is tell you whether the turbo is knackered or
not.
Mike.

My mate had a cavalier. I'm not sure how closely related your turbo
lump is to the 2.0 lump in his H reg 2.0GLi, however he had a periodic
burning smell through the vents that turned out to be the rocker cover
gasket weeping and causing a drip on to the exhaust somewhere. The
internal blower fan sucked smoke into the cabin.

This seemed to have been caused by Vauxhall being cheap bastards and
using cork gaskets.

Might not be the rocker cover, might be somewhere else, but I'll agree
with you and other posters that if the turbo was leaking internally then
its unlikely you'd not notice oil in the exhaust.

I had a couple of turbo cars, both Saab 900s. When the turbo seals were
failing on that, it was extremely obvious because it used to smoke a lot
when hot after a run, or when applying power after being on the overrun. And
I mean a lot - sit for a minute at lights, you'd be shrouded in smoke. You
don't smell it in the car when it's moving at all though.

Your problem sounds much more like a leaking rocker cover gasket or seal
somewhere that's weeping oil onto something hot, which is where your smell
through the vents are coming from.

 It's funny you say that, I have a problem also with the heater motor I
think I was told.. the fan doesn't always come on when I start the car,
then if I go over a bump it will start.. this is occasional.. but could
it be related??

I think the coolant system is fine, although I have had a new radiator
fitted about 6 months back..

Thanks

Dave

 The engine seems to run as normal, I haven't noticed a lack of power or
any smoke from the exhaust.

I thought it was a ridiculous quote, I won't be getting them to do any
more work now anyway, sounds like they haven't a clue!

 Thanks for the reply Douglas. I'm glad to hear that the turbo sounds to
be OK. I don't know what Vx use on this engine for gaskets.. I will try
to get the car on some ramps and see if I can spot any leaks or trace
any smoke.

Thank you

Dave

 Well that sounds a horrible situation to be in, and i'm definately not
getting anything that bad so you're probably right. I will get it
investigated more based on all the advice from you all.

Many thanks for the help.
