Smoke Issues

[Camotec]

Ok well today i replaced all the vavle seals but i am still getting this smoke when i back off and then put my foot down again and when going down a hill while backed off and while idleing sometimes ??? what could it be?

[scum]

turbo? damaged valve stem? i dunno. why are you asking me? o'... wait.. u'r not. :D

[Camotec]

I checked the stems and they are straight did that while i changed the seals with a borascope and I don't think it would be turbo, not with those symtoms i should get smoke on boost and it would be white smoke this is more a grey smoke (oily) i think.

[Rassy]

It could be your turbo expecily if yar running a bit of boost an the rings or the boars are worn a bit creating preasure in the block an so on, but my car when its cold will throw out a sort of grey smoke that just looks like fuel but that because I need new injector (well thats what I tell myself) but I forgot what your problem was an jsut remebed about another prob I have with mine.

Cheers Rassy..........

P.S. If it aint realy blue or white smoke it aint oil.

Are you sure its not Black? You've just fitted a BOV right? Could be rich spikes when you BOV opens up... Every staz ive seen with an atmosphere venting BOV has puffed a little black when the BOV opened...

[Camotec]

yeah nah definetly not that, still smokes when the vacuum connection to the BOV isn't connected.

[ProZac]

Well... crap. The first starion i owned had the same problems, i replaced the stem seals and it got a little better, but the seals in the turbo were stuffed aswell, i replaced the turbo and it was all good. I rekon just keep an eye on the oil and dont stress over it :)

[Alspos]

Sounds like you blew a seal. Umm no, I didn't mean blew a seal, I just meant you blew... umm like, well, just say it was ice cream.....

[Camotec]

i am betting it is the turbo, which if it is i will be getting a costom manifold made up that won't crack, anyone got one or know where i can get one premade without costing major amounts etc.??

Cheers

Hey Al, what you smoking?

[StarionChef]

custom only Ben. make it yourself for a few hundred, or pay a shop 700 to 1000. (very approx.)

[Starion VR4]

just a few things to check, 1: your PCV valve is in good working order?,
2: that your charcoal canister isn't full with oil, your oil seperater on air cleaner isn't blocked or full with oil? symptoms sound like high vaccum are doing it so not necessarly ring. 8)

[Camotec]

Hey VR4,

where is the charcoal canister?
and where is the air cleaner, what the air filter??? looking for the oil separator got anypics to point it out to a young fool

Hmmm, Yes, the classic penguin joke :)

Anyway,

Check your BOV. Make sure it's holding up under pressure. It may be
opening at high boost. Especially without the vacuum connected. Don't
forget the vacuum pressurises under boost...

I set my last BOV to 1PSI over max boost to avoid that.

Anyway, check for oil-cap-jitter. (If you loosen the oil cap when idling,
does it

a) Jitter
b) stay still, nothing unusual
c) Seem to be sucked down slightly.

What it means.

a) Would explain smoke.
b) Isn't great, but probably isn't bad either.
c) Is fantastic... Good rings.

Other than that, check the static seal at the back of the turbo. Look for signs of oil leaking from the snail clamp.

David.

what would be the cause of valve seals going?

Camotec, did you also check the valve guides?
