To much oil

[Wayne]

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 

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.

no no havent touched the car since i noticed lol skint atm so having to wait untill payed (2weeks) to get anything done, getting a decat off of a mate on payday also so i will see if theres alot of oil sitting in there lol just hoping its ok :\

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

[rockmonkey69]

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!

[rockmonkey69]

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.

[DubAndDubber]

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.
