[RESOLVED] New kinetic G50 blowing smoke?

[TiradoCC]

Where did you purchase the turbo from?

 

[pmanaresi]

i bought it from slow boy

Contact them first before you do anything else, I'm sure Slowboy will take care of you.
We didn't purchase it from them so we had to deal straight with Kinetic

You still haven't told us if you have a catch can setup and/or how it is routed. Excessive crankcase pressure can cause these signs as well, and it's worth looking in to. It doesn't take but a few minutes to do.

Also, another shot in the dark, but how good/new are your valve seals? Leaky valve seals will let oil into the combustion chamber to burn off. It's just an idea to look at, but I doubt it would have oil seeping into your O2 housing like you said earlier. Back off the exhaust manifold and see if you have oil in the runners/ports. If you do that could be a sign of a fault with the head/seals.

Sorry you're having no luck and I'm sure it sounds like I'm throwing out shoddy info, but I'm just trying to suggest any possible problem that could create symptons like these. Just trying to help.

You "wisemen" crack me up.
To the op, let me know if you have problems with Kinetic if you decide to contact them.

OP had bad smoking problem. Turbo had shaft play. OP rebuilt it. Still smoked. OP swapped for a brand new turbo. Still smoked. . . Glad we amuse you

 

[pmanaresi]

no i appreciate any ideas that you have for me. my pcv valve is removed with a free flowing fitting and both valve cover vents are run to a catch can. when i removed the 20g i pulled the manifold and there was no oil in the ports or the upper part of the manifold. on the g50 setup i have now i pulled the plugs and my egt probe to check for oil and there is none. i believe that this g50 is bad and will be getting a different turbo from slowboy. i hooked up an oil pressure guage today at the ofh and idle pressure was between 30 and 40 psi. i pulled the drain off at the pan and ran the motor for a few seconds and the oil was drain out in a small steady stream. i dont believe the oil is coming from inside the engine. the engine has just under 10k miles on it. i built it myself with new everything (including valve stem seals) so i would doubt they had failed even if i had any signs of oil in my cylinders.

well that is not entirely true. as i mentioned before the 20g i had was a replica (aka ebay garbage). unfortunatly i didnt know this until it started throwing tons of oil and i tried to get a rebuild kit for it. i did rebuild it with an mhi 20g rebuild kit but i think this turbo was beyond rebuilding- which is why it still smoked up a storm. the g50 however smokes very little at idle. there is no other way to explain this other that the new g50 having a bad seal. if my engine were blowing all the smoke than it would still be blowing just as much smoke as with the 20g.

Does your catch can vented? Basically, does it have a way for it to release pressure or is it a sealed can like the Megan Racing?

 

[pmanaresi]

yea the catch can is vented

 

[mach4g63t]

yea the catch can is vented

Well, um... I'm out of ideas. I hope Kinetic or Slowboy or whoever does something and helps out your situation.

Like others say.. Talk to SlowBoy and they should take care of you.. I have the G50 form slowboy.. Not a SINGLE prob so far.. 3 months into it.

your turbo not having problems doesnt help me. slowboy had me send it to kinetic in canada. it will take over a week to get there. then they will inspect it for 2 weeks, then decide if they will send me a new one. that would be fine if i hadnt waited for over a month for them to ship me a blown g50. so yea slowboy have been a real help

 

[pmanaresi]

UPDATE***

Kinetic received the turbo and they said everything is fine. Im not sure where to go from here. My brother seems to think i should try to get more crankcase ventilation by way of an extra vent on my valve cover. i plan on exploring this, but dont really see why i would need more ventilation as i already have both the pcv valve removed and vented and the other vent both ran to a catch can (with a vent).

 

[dsm-onster]

Did you get the turbo back?

Considering how many turbos you have had and ALL of them are smoking, it makes sense. Is your PCV vent possibly clogged in the valvecover? The PCV valve ventilated via vacuum from the intake manifold. Perhaps you need to have an actual vacuum source for your motor? I've heard of some having slight smoking issues without having the fumes building up in the crank case sucked out. . .

You mentioned that the car smoke non at all until the ebay 20g blew, correct? Could some debris found their way to the rings?

Also one simple issue could be this: are you feeding your turbo from the OFH with no restriction and have no bshafts and no ported oil relief valve? There's also a discussion on here about the return line oriface being too small for garrett and holset turbos. Holset requires 19mm diameter minumum. Don't know about garrett.

I'll stop by this weekend and do some brainstorming this weekend with you. Be around?

How long did you drive with the new turbo on for?

When a turbo on mine blew up it took at least 200+ miles for the oil to burn out of the exhaust. Yes, after 20 miles I could idle the car with no smoke, but once I would get into a pull and the exhaust would really heat up. It would start to smoke again.

hey jj wish i had seen this post before now, i was around this weekend. i didnt drive more that 5 miles. under boost there would be clouds of smoke out of the exhaust. i should be getting the turbo back this week sometime hopefully. evan seems to think i might have to much crankcase pressure so i got another valve cover and i am drilling an extra port for ventilation and making them both larger than the single vent on the side of the cover. if you have a leakdown tester you could bring i want to try this and see if maybe something internal is leaking

 

[slowgsr]

drain should be -12 no 90' fittings, only 45's. You plan to feed from the head.. Next time you have the head off I suggest porting the oil gallery that feeds the head. This will help increase oil pressure to your head.

Goodluck.

porting an oil gallery would decrease pressure and increase flow

 

[phill]

I was going to say that you're probably just burning the oil that dumped down your exhaust pipe, but somebody already beat me to it

So how many total miles have you put on the car since swapping out the blown then rebuilt turbos?

i didnt drive the car at all with the 20g after i rebuilt it- for some reason it was still blowing just as much oil past the seal. with the g50 though i didnt put many miles on it. less than 5 before i sent it back. i had alot of smoke out the exhaust under boost.... i guess there is a possibility that this was only residual oil from the 20g spewing so much oil into my exhaust. i get the g50 back on monday and i will be testing this theory and others and put some miles on the turbo to see if the smoke subsides.

 

[SBR Joe]

i bought it from slow boy

PM me with your first/last name and contact number. Ill check the date of purchase and get an RMA number from KNE to have you send it back for warranty and see what they say. Its not the first time this has happened at all. The G50's seem to be more trouble than the G60's for some reason.

 

[pmanaresi]

thanks joe but i had already sent it back and kinetic told me nothing was wrong with the turbo. Now that i have the turbo back i have reinstalled it with a modified valve cover with extra crankcase ventilation. i fitted the main vent with a 3/8 npt vent and made an additional 1/8 inch npt vent next to the main one. I no longer have any smoking issues with this turbo. unfortunately now my act 2600 has taken a shit on me and i will have to pull the tranny this weekend to see how bad it is. if its not one thing its the other...

ok buddy. well if you need anything just give me a shout, ill take care of ya.

 

[tim4g63fast]

it looks like you have the sbr return line kit i did

not trying to bash a vendor but I was unimpressed with the fittings that came with mine.

my biggest concern with the kit was that the fitting they provided me for the outlet was actually smaller than the outlet on the tubocharger. the hole on the flair cone male end seemed to be the correct size, but if you measured the hole that would mate flush to the turbo it was considerably smaller than even the stock return line.

I may have got a bad fitting, or maybe you should check yours, never the less it is a easy fix if you have access to reamers, but its deffinatly the type of thing I wouldnt use a drill bit on, you want to keep it nice and center and honey baby smooth, if you went trying to upsize it with a drill you it could grab and screw up the fitting..

just an idea
