smoking
 

i just installed my turbo and when i come to an idle and sit for a second smoke will rool out from the hood. when i take off the hood the smoke is coming from the turbo. i was wondering if it could be the coolant lines are backwards? i didn't try to find out which ones went where. their seems to be a little bit of oil on the intake housing but not enough to make it smoke like that. anyone have any thoughts?

Re:smoking
 

is it a new turbo? if not then sounds like blown seals. time for a new turbo or rebuild, both will cost about the same.

Re:smoking
 

no it is used. is there anyway i can fix the seals.

Re:smoking
 

Give it a little time to dry the oil. It might just be the oil you said was on it.

well i didn't exactly get the intake housing snug after rotating it. i hope that is all it is. i need to tighten a couple more bolts i couldn't get too today also. but ya'll don't think it is the coolant lines?

Re:smoking
 

I doubt the coolant lines would be causing smoke. Maybe if they were spraying coolant on the hot turbo. Tighten up the turbo and se what happens.

no i dont think the lines would do that, to fix the seals you need to rebuild it w/a rebuild kit.

Re:smoking
 

where do you get the rebuild kits?

Re:smoking
 

Make sure your return line is not backing up. Make sure the angle is fine to dump it into the oil pan. If it does not it will cause smoking if this is not it it is the seals. Went through the same with my first turbo.

Re:smoking
 

well, the outlet on the turbo points down but because it hangs so low the return line goes up into the oil pan. to make it go down i would have had to drill into the sump and then it would have been straight across.

Re:smoking
 

thats probably part of your problem. the oil has a hard time getting out of the turbo putting extra stress on the oil seals and causing them to leak. either get a new manifold that locates the turbo higher, a new turbo that sits higher, or a scavenging pump and a oil resevoir that sits below the turbo seperate from the engine oil pan.

Re:smoking
 

the oil is leaking into the downpipe. i think i want a manifold that sits higher. could it be leaking out the seals and they not be blown where i can just put an hf manifold or aftermaket turbo manifold on and let it go?

Re:smoking
 

what kind of manifold is that? i have never seen one that put the turbo that low... i didn't think of that possibility.

Re:smoking
 

we fabricated it from a civic 4-2-1 manifold. anyone know if seals need to be fixed or are they okay.

Re:smoking
 

please help, just bought turbo header and am looking at different turbo. do you guys think it needs rebuilding?

Re:smoking
 

well its a little hard for us to tell if it needs a rebuild without looking at it. If the turbo is smoking, and your oil return is smooth, and you have no external leaks, it probably needs a rebuild. Most junkyard/used turbos doo.

thank you, i am going to try a different manifold before i do anything. this turbo was in good condition when i bought it, so hopefully it is alright.
