mechanic question: oil visible on Engine thing

Hi,
Any mechanic here? or someone with a bit of engine knowledge?
Basically I saw a 2nd hand car with that "oil thing" in it.
It seems oil vapour residue, normal as per the "dealer mechanic".

But I saw like 1cm oil drop that seems "fresh", not vaporised as in the pictures-

Could it be some kind of dangerous leak?

Does it seems normal to have such "vapour" on a 2.0 engine, 96000km?





Thanks!!

Re: mechanic question: oil visible on Engine thing

depends on the price of the car

oil leaking from an old car with high mileage is pretty much a given.

could it be expensive? yep, or it could be really cheap, eg just a rubber washer corroded around a breather pipe.

ok then at that age etc it really shouldn't have an oil leak. plenty more for sale out there, if in any doubt just walk away.

Re: mechanic question: oil visible on Engine thing

I have a 25 year old car which doesn't leak oil. There is no excuse for a car built in the developed world* to leak.



*Unless it was built in the UK.

Re: mechanic question: oil visible on Engine thing

Thanks, you're right.

Their mechanic said the "vapor residue" is normal on all diesel engines.

That's only the "fresh drop" that was suspicious.(not visible here)

That thing on the picture (approx like greasy traces), where we can see my "finger mark" is that common on all engines?

Is that from a "leak" or like just normal vapor?

iirc its been illegal to vent oil vapour for quite a few years, most cars recycle it back into the manifold, so I think your guy is telling porkies.

It was a cheap shot I know. After all, at some point a British engine will dump all its oil on the road - either dripping it out slowly or the bottom end letting go. The latter, obviously, the more common failure

Saying that, the high revving engines from Munich (and also Buchloe) are known to like a bit of oil - especially if they are used frequently in their upper ranges.

Anyway, back to the OP. I have yet to look upon an engine bay in Switzerland that isn't immaculate - without a hint of oil. Certainly the MFK inspectors are keen to fail any car which makes their hands dirty.

Re: mechanic question: oil visible on Engine thing

Thanks,
I'm pulling off the "deal" then

I had other feedback on other forums, it seems not such a good price anyway.
