today i noticed when the car would build boost i could smell like something burn its also is puffing black and white smoke not alot just a little

smoking when under boost or when you let off and in vac?

 

It smokes when jus cusing but when I get on it n it builds boost I can smeel somethin like burn

 

what should my compression be at
could it be how my return line is ran

 

Hows your crankcase ventilation set up?

Edit: I really dont like the look of that flow of the return line.

theres a dip in it where the oil flow should be smooth.

 

i havent done anything with it its just open . ya i wounder if oil is getting stuck in the line

 

oil might be spraying out and burning on your manifold. I had that same problem.

 

ya i need to get a catch can but the white and black smoke comes out the exhaust. when you give it gas you can see little puffs of smoke

 

Could be valve seals

could be turbo seals

 

There is maybe 30miles on the turbo could the seals go out that quick

 

Yes. If the oil isn't draining properly, you can cook your bearings in the turbo. Seals do go out if the oil is being cooked right next to them! Fix that return line

 

Ok any pics of how I should run it

 

The lowest point of the return line should be where it enters the oil pan.



and this one, short & sweet!



But please, never do this! Shandy was an actual company that made turbo kits for motorcycles. Look at the oil return line!

 

looks like you need to get rid of the adapter on your turbo and use a flange with the an fitting already on there so you can get some clearance.

though i'm not convinced this is your issue since you said its black smoke.

 

Both black n white smoke it will puff a little black then it'll puff black but I think there could be oil from when the seals went out on my ebay turbo

 

Is there a lot of moisture around? Do you have a high flow cat? Is it always black & white smoke or only when you're on it, decelerating, at a stop, vac, etc...

The more info the merrier.

 

Has no cat has a test pipe. it only smokes under acceleration I've let it idle in my drive way n seen just a few little white puffs my girl was behind me and said when I got on it a big puff of white smoke came out

 

sounds like blow by to me.

 

x2

The smoke is always there, I have to agree with Esoteric

 

ok thanks

 

is it normal to have some also what oil are you guys using, what should my compression be

 

160-180 is what i always went by.. but others might use another number.

do a compression and leakdown to determine the health of the engine. Another way to tell is when the oil pressure starts to get lower slowly over time, then its on its way out and you have limited time.. so save up for another engine or be ready to tear this one down.

 

I did a comp test n it was 150 across n a local shop said the rings r getting ready to go so ill probablly tear it apart again and have to replace the rings I didn't thiny the rings would go within 30miles

 

If they don't seat properly, they go pretty fast!

 

Ok thanks for the help how do I make sure they seat properly
