Would a kinked turbo coolant return line create too much pressure in turbo and cause coolant burn? I am guessing yes it would but I am trying to see other opinions. Would the turbo go bad after that incident? It was smoking for 15 mins before I shut it off because I was tryinh to figure out what happened

I started my car and let it sit for 20 mins when all of a sudden white smoke started to pour out the exhaust. I tjoight my turbo went bad so I was about to change it to my stock turbo when I found the kinked turbo return line, its a rubber hose. I cannot for the life of me find a hose that will connect right. is there a way to hook the return line without kinking?
This is a stock return line btw.

 

No it would not. Are you sure it's not oil? Also what turbo are you running? When the motor is cold and you start it up does it smoke? If not does it smoke after it's warmed up?

 

I will start it up tomorrow at lunch time.

White smoke billows out the exhaust, and it does smell a little bit like burning coolant.
Its a BNR stage 4 turbo

before it started to smoke out, it was running fine, no smoke at all until today and thats when I noticed the kinked turbo coolant return line.

 

I've got a CHRA taken apart right now, and the water passageway is completely separate from the shaft/bearing/seals. It would have to overheat and crack to send coolant into the exhaust. You'd probably end up with coolant in the oil too if that happened. But I don't think it could overheat while you still have oil pumping through it.

 

I just started it and in brighter lights it is definitely blue smoke...so my turbo must be bad from no coolant flow
Bad oil seals on turbo. It smokes right away from cold startup gets heavier as engine warms up

 

Blueish smoke should be oil, but I can't see how restricted coolant flow could damage the oil seals. There are plenty of oil-cooled turbos out there that get by fine without coolant. As far as I know, it's primarily there to cool the turbo after shutdown to prevent oil coking.

 

Just took off the turbo and the turbine is soaked with oil. The manifold is dry so from deduction its the turbo. Guess I have to send it off to bnr now to rebuild.
