Title: To much oil
Post by: ShauniiBoii on 25 January 2013, 14:46
High there im new to the golf crowd so my question is would a high level of oil cause smoke to come out exhaust? iv noticed (not everytime i start) but say i leave it a couple days go to start ALOT of smoke comes from exhaust pretty much hides the car, i thought maybe engine / head gasket was wrecked, checked under oil cap and its clean as hell under there, checked oil level and it comes up to the 1st yellow bit thats on dip stick which is far to much!

so is engine a write off or is smoke due to amount of oil in it?

Thanks for any help guys :)

over filling with oil will just damage the cat, the excess oil will sit there and that's why you get a huge cloud when starting

as said, remove what you can or drain it and add new to the level

That much of an excess can destroy the engine, better get the oil level addressed.

Yous hould be able to drain some out via the dipstick tube.

Clear plastic tubing and a syringe will do the trick.

Is it really worth doing this when the oil prob needs changed anyway  :smiley:

If the smoke is blue then it's goodbye turbo seals...

Nope but I only suggested it in case it was not due an oil change.

going to replace the oil what should i go for? im going 10-40 but did a search and alot of people are saying full synthetic and alot are saying part synthetic... has over 100k miles so should i go part?

and yh it blows blue snow but not every time you start it :\ jus every now and again

I'm hoping you haven't continued to drive the car knowing the oil level is significantly over filled. I would use fully synthetic. The engine might not have been damaged but burning oil can clog up the catalytic converter.

Stem seals can also go with to much oil due to the pressure, which gain leads to blueish smoke

Not sure it poses a problem to the valve stem seals, oil pressure remains unchanged.
Oil density remains constant as does oil flow rate because that's directly proportional to the rpm as the oil pump is chain driven by the crankshaft.

The op says he has blue smoke, which is stem seals... To much oil with already dodgey stem seals means, well, goodbye seals!

The blue smoke which is oil being burnt is not from the valve stems seals but the excess oil on the bores of the cylinder and not the valve stem seals.

Why? I hear you ask, it's simple really, consider this:
 The volume of oil to the head is directly dependent on the oil pump, this is dependent on the rpm and not the volume of oil in the sump. The pump will flow the same volume of oil whether or not it was over filled.

Simply put the oil pump controls the oil to the head of the engine.
Should it still smoke a little after refilling with the correct oil level, then you still have residual oil in the catalytic converter and any baffles in the exhaust system. As per above, drain the oil and refill to the correct level then drive for a while and it will clear.

I agree, but he also states he only gets the smoke now and again. Which makes me think the oil is dripping past the stem seals while parked and then getting burnt off after start up.


P.s, I don't need a lesson in engine technicalities thanks. Been there done that. So there's no need to be so condescending when you speak.

I think you might have misconstrued that, there was no such intention to do so. My posts are meant as much for everyone on the forum as well as the OP with the intention of ensuring that members are well informed.

Based on what the OP has said with regard to oil level, it seems far more likely this is the cause of the burning oil than failed valve stem seals.
I would advise that the oil level be corrected before proceeding.

I think you're getting off topic a little here.
I like to be coherent and concise, you've clearly misconstrued this as a personal attack. I can't really apologise. It was not aimed at you, there was no reference to you and it is posted on a public forum. Not all members are as technically inclined and it helps to be coherent.

In the future avoid using someone else's thread to raise your concerns, that's what private messages are for.

Back on topic though, previous post with regards to increased oil pressure to the valve stem seal because of overfilled oil is incorrect, the oil is entering the combustion chamber because there is more oil on the bores than the piston oil scraper rings are able to handle. Let's get the oil level within correct levels first then go from there.

you have both given valid points for what ' could' be the cause, job done

Not wanting to wade in on this highly charged argument, but I agree with this.

It's not to say that the stem seals aren't the problem. It's just far more likely that overfill is causing oil to get in every other way it can. I'd also say it's worth a check of the PCV + pipes, that much oil will be desperate to get sucked through the breather pipes.
