Smoking Turbo?

[Seti]

Good afternoon all,

I've got a problem with my Ty burning oil. It's pretty much stock still but does have a newer motor which has almost 50K on it now. However when I bought the Ty it was smoking when I let out of the gas. It only does it when it's up to running temp. It had been leaking oil and when I got a full tune up they discovered it was the oil line from the turbo. Had two lines replaced and the leak stopped but the smoking didn't. Still it only smokes at full running temp and then it's only noticable when I let out of the gas or when i'm idling. Even when I'm cruising at low speed it doesn't smoke until I'm out of the gas.

Another issue I'm aware of is that on occasion when starting it cold, the turbo makes a sound similar to a loose serpentine belt only not nearly as loud. It stops after a minute or so and it doesn't do it every time but enough to give concern.

Lastly the oil pressure has noticably dropped. When I first got the Ty the oil pressure was low like it is now, just about 30psi at idle and maybe 50psi when under power. When I got it back after the tune up it never dipped below 50 even at idle. Since the turbo noise started the pressure has dropped and the smoking seems worse. I'm pretty sure the issue has to do with the turbo but I'm not sure if it's leaking internally and blowing it out the exhaust or if it's not getting enough oil or what.

Does anyone have any idea as to what could be causing this?

Thanks,

S.

Re: Smoking Turbo?

Sounds like the turbo seal on the exhaust side is letting go. Could be valve stem seals with the symptoms you've got too.
You'd realy have to take the turbo off to inspect it with any accuracy. Look for signs of oil in the charge side tube or where the orange 90' boot connects to the air cleaner pipeing first. If there's oil in there it's a good possiblity the turbo needs rebuilt.
I don't like the sounds your describing coming from the turbo.. if it's putting shavings in the intake side .. it's going directly into the engine... also could be contaminating the oil... The sooner you get that checked out the better...!!!!

Re: Smoking Turbo?

if i remeber correctly there is no "seal" on the turbo.
if you have too much oil pressure(never heard of on syty??) or drain is restrictive, this will cause the oil to over flow out of center section of turbo and into turbine side(exhaust side).
also if you have internal damage to turbo its going to pour oil into exhaust side.
you also might want to look at the PCV's(im not sure if this could give you those symptoms)

Re: Smoking Turbo?

there is a seal on the turbine side looks very much like a piston ring. if that thing lets go it will smoke badly. more tha likely you have a turbo on the way to an early death.

There is indeed oil spots around the turbo and she's heading into the shop Thursday morning.

Thanks all. I'm hoping the damage is limited to the turbo itself. I suppose this could be used as an excuse to upgrade the turbo and down pipe no?
