R34 Gtt Turbo Coughed Oil Out Dump Help?

[nismokiller]

my r34 gtt had been sitting for a while and i just had new oil chucked in, plugs, and cranked her over (open dump ) and the turbo spat a fair bit of oil out the dump? could my turbo be gone? its got no shaft play, no stuffed fins, physicly looks great ? i dont really want a turbo upgrade as it was fine for my likings previously

anybody got a idea? theres also abit of oil in the front of the turbo aswell ?

oil in front -blow by recirculation (normal)

oil out dump- slight wear on valve guides allowed a few drops in the chambers from sitting so long , got burnt on first start up.?

yeah well it was a lil wild i took pics of the fins etc, im not running any more boost then standard so I wouldn't of assumed its popped as the fins are perfect too, a whole oily smoke cloud and a cough up of oil came out the dump( first time start today since march or april . I haven't attempted to start it again after the oily incident

[AngryRB]

hard to say without the history of the car etc, sounds odd, at times like that with long periods of not starting i always disconnect fuel pump, and make sure i crank the engine for a while to make sure it has some oil in the top end before starting it.. starting to sound like a blown turbo seal, you shouldnt have actual oil coughing out i dont think..

[hypergear]

Well you can start by checking engine oil level making sure it’s not over filled and the rubber on the hard oil drain pipe is not kinked or blocked. The turbocharger usually leak out oil from both ends if it can't drain oil fast enough or can't drain at all.

Once above has been checked with any issues repaired, start and idle the car for couple of mints see if the smoke clears away.

If not it would be likely been that this turbocharger needs a service, Do check out our turbocharger high flowing thread and alternative options available if that appears to be the case.

i replaced the lower line as it was destroyed nearly, the oil feed seems all the go, but mind you the motor basicly was started for a very very short period of time..

[nismokiller]

i removed turbo for replacement but basicly ran the car one more time and found the turbo was flushing oil up and out the mouth? the seal must be buggered then?

[AngryRB]

how much oil is in the sump, have you made sure the oil is actually returning in the sump or the sump isnt way over full like hypergear said?

i was of the opinion that the oil flowing thru the turbo and down that return was not a great amount, so to be flushing out the mouth kind of sounds like theres a blockage... id investigate more before turbo replacement...

[abr33]

So your positive the oil dump line is totally un-blocked?

If so, your turbo definately needs a service or replacement

[nismokiller]

the oil return line was replaced by me flange and all fitted and a new hose was fitted, had so much flow could compare to a radiator hose... (sarcasm) and the feed lie has no dints not damaged everything was fine...if i run the motor with the feed and return DCd i should see oil come through the feed line correct? ill double check it tomorow.. all i know is ill be chasing a r33 turbo if anyone has one there keen to get rid of?

[nismokiller]

another theory was that it could have been heaps of blow by that went through intake and out the top feed of the turbo? i put 4.2L of oil in my neo, dipstick reads perfect,

Im running a impul r34 computer.. im not sure what its capable of, but if i bolt another turbo onto it and run a few pounds more, will the computers air fuel ratio work it out so i wouldnt require a retune? or will i need a whole new computer all up?

What do you mean blowby went through intake and out top feed of turbo?

[nismokiller]

well you have your breather tube that goes into your intake ? from your covers? Just a theory , but what if oil had come through there and out the top (intercooler pipe) I really wanna sus this out just so i have a good understanding of the problem im currently facing!

[abr33]

Id find it hard to believe that oil thats been sitting in your intercooler and piping could get sucked up enough to spit oil out exhaust at idle, I know what you mean though, and very possible theres oil in your intake, but cant see that much getting in? Have you tried starting it again?

[nismokiller]

it came out the exaust and intake >.> ^^^ i cracked the front cover open , ran oil through it with one side blocked, within a few spins i found the the shaft was leaking oil both intake and exaust side!
