BLUE SMOKE! HELP

HELP

Blue smoke coming from the exhaust and quite alot of it.

Plum of blue smoke when accelerating.

Also noticed when when it was in a high gear around town with foot off thr throtle.

Dont think its piston rings becuase theres no chuffing when the oil filler cap is removed.

[CALICO 130]

valve stem seals maybe if not then rings

The garage that will be doing the work (ACR) suggested getting the chain done while everything is off. HOw much are the chain kits?

Dont think it will be piston rings cos theres no back pressure when the filler cap is taken off.

Ive only just noticed it today. My friend said it had the off bit of smoke the other week, but nothing to be worried about, but today it was really noticable.

Ive been told to check the breather pipe to see if its blocked or collapsed. The garage said its a sounds odd that it only just started smoking yesturday cos if it was stem seals it would have happened gradually.

Can anyone direct me to the breather pipe?

If if nots that what would you get replaced if the head was off. Or possibly the engine and box out to do the chains?

Thanks

Breather pipe seems fine.

Could it be piston rings?

I've just spent £1100 getting chains, guides and tensioners done. Get yourself registered as a premium member and you will save a fortune on genuine parts from TPS. I saved around £200 on all my parts but you DON'T need the chains doing to change the stem seals and you can check the top chain guide whilst the rocker cover is off. If the top guide needs replacing then the bottom one probably will too. You need to take the head off and the gearbox off to change the top chain so start saving!! My cheap car turned out to be an expensive car after the head gasket went and the guides were worn!

Done a quick conpression test on cyl 1 and 2

cyl1 - 130

cyl2 - 170

Getting new spark plugs and HT leads cos the spark plugs were black.

The was was over fueling when I bought it cos of the lambda sensor so going to charge the oil aswel. It was only replaced 2k ago but it was still over fueling when it was changed.

Put a catch tank on and blocked the breather to see what it does. Its reduced the blue smoke a bit ( I think)

in my experiance if its blue smoke on start up it's valve stems n guides

if its still smoking while driving its piston rings are worn

[VeedubVR 0]

Its not smoking when it first start it up or on tick over

have u checked compression on all 6 cylinders? they should be all nearly the same compression result? if you get one or 2 thats miles out could be faulty rings ie like the ones u listed above. I had my piston rings go on my fiesta and they just went all of a suddern. you can get sum piston ring sealer paste which stops the oil breathing so much, its a cheap fix but one that shouldnt be done.

another sign of worn rings is a massive amount of oil in breather pipes. ie when u take it off oil runs out of the pipe! are you losing any oil?

[VeedubVR 0]

It doesnt seem to be using alot of oil. There was a very small amount in the catch pipe this morning. Well i think its oil, I havent properly checked.

All 6 cyl will be getting checked on wed when it gets new spark plugs and HT leads.

Whats normal compression rate?

[RAPgolfvr6182 2]

not sure it doesnt say in my golf vr6 work shop guide

[VR6Nat 9]

i believe it is meant to be anything between 145-190 psi but thats only through memory and mine isnt amazing!! lol .

As said above thought they should always be a similar result... not 5 @ 170 and 1 thats 130.... that could indicate a problem.

[mcmark 0]

new engine 145-189psi (10-13bar)

wear limit 109psi (7.5bar)

Max difference between cylinders 44psi (3bar)

Back pressure when the breather pipe is off mean whats?

If you have had too much fuel washing the bores then you might have damaged the rings and bores through loss of lubrication. This might explain the suddenness of your symptoms. Just an idea for thought.

[VeedubVR 0]

Expensive job?

Will it have to be rebored and bigger pistons put in?

We are going to change the oil in the next week see what that does. It had it changed but beofre I ot the senor replaced. Should I keep with 10w40 silver sytna?

could this happen during some remap work?

It would have to be over a period of time and tuners are more than aware of this. Depends on the amount of overfueling as to speed of affect.

it is possible then, thanks mate :-)

I get blue smoke on over run. The other day I noticed it when I was letting the car coast down a big hill while still in gear, I could see the smoke through the rear screen, a friends does the same..

I have an oil breather filter on the crank case, my car does use some oil but i did spot a leaky rocker cover gasket so this could be playing a part..

My car does run very rich and I can't work out why, lambda is brand new, so its the MAF, so is everything actually..

[/quote']

Same here. New MAF, valve guides, rings everything except a new lambda, starting to run out of ideas. It must be a problem some one knows about.

Getting to the point of thinking about getting a second VR, the amount of money I've thrown at I could of bought another one in better condition!

[VeedubVR 0]

Just changed the oil today so im hoping this might fix the problem.

Is it actually worth using a catch tank? Ive got a temp one on now and its got alittle but of oil in the bottom. Would that clog the breather filter up? (Valve is broken, so had to re-route it)

Seems to be alot of VRs blowing blue smoke,

[benovr6 0]

blue smoke on overrun may be worn valve stem oil seals, my old rado did this,they were knackered
