Does This Sound Like Turbo Seal ?

[tricstar]

as the title says its a turbonetics 850 turbo, with less than 5000kms on it, and currently only 18psi...

it only seems to blow blue smoke if I start it with in 0-20 minutes of turning it off, while everything is still warm,, if its been sitting for an hour or two or over night it doesn't, and don't think its blowing any on normal driving or under boost, does this sound like turbo seal?? I'm thinking its turbo seal because when its cold then the exhaust is'nt hot enough to burn off what little oil has leaked out straight away, and maybe just burnds it off slowly as it warms up without me noticing, ???

if it was valve stems leaking I would expect it to smoke in the morning and after an hour or two when cold as well ??

You need to check your oil drain setup if it was doing that from the date you installed it. Also check to ensure your engine is not overfilled with oil.

Else check turbo for back n forward and side to side shaft play. Excessive play mean worn bearings (and seals) due to oil starvation or contamination. If that is the case ring up your supplier for support and repairs.

thanks Stao, no wasn't like that from install, just started, and engine isn't overfill..

to check shaft play, is it as simple as pulling off the pipe off the front of the turbo that goes to the intercooler, and check for shaft play in there, or is it turbo out job ?

wouldn't have thought oil starvation, its got a Jun oil pump which sits at 4 bar even at idle ( well 4 on the standard oil pressure gauge, not sure if thats bar ) but you agree its likely to be turbo rather than engine ?

ok,,, asuming its the turbo seal, how bigger job is it ??

thinking I might do it, just so I can rule it out,, sick of leaving everywhere in a cloud of smoke

Well the restrictor is on stock oil feeding line. If its not drilled out then that might be a problem. Also is this the Ceramic BB units? If the wheels and shafts are in re-useable condition it shouldn't be too expansive to repair, other wise it could be very costly.

Its best to speak/email to your supplier or manufacture for support, they should be able to assist you on repair.

thanks again

Its a GTK-850 ( ceramic BB ?? ) I'll have to find out from the engine builder if he drilled out the oil feed.. I take it from what you are saying the standard size feed line is inadequate for this turbo ? it was running 24psi @ 760hp at the motor..

I'll have to find out where it was purchased,, I bought this setup immediately after it was finished, now to sort out the gremlins

cheers
