Smoke!!!!!!!!!!, i have searched Options

[Dickster223]

i recently turboed my 7afe with tons of probs. finally getting everything right and it starts smoking under boost. but only if i boost for more than and few secs. the turbo was rebuilt less than 500 miles ago and my engine runs good out of boost no smoke. to me the smoke looks grey. I recently had my turbo blow the oil seals out and oil was everywhere in my intercooler piping. I have cleaned all of them and the intercooler. I also cleaned the intake manifold the best i could. would this have any thing to do with it? any other ideas?

Thanks
Richard

you are undoubtedly burning oil. searching that.

wheres the smoke comming from?

[Dunners]

Is there any smoke coming out the exhaust? oil might just be slipping past the oil seal and dripping into the exhaust housing, it would explain any smoke coming out the turbo or cat. I don't know why it would only happen under boost. Does oil pressure increase under high revs? If it's just oil slipping past maybe you could put a oil resistor in but only if the turbo still gets enough oil. good luck.

check the size of your feed line and make sure there is no bends in your return line. the same thing was happening to me when i first turboed my 7A. if the feed lijne is too big or the return line is bent you will blow the oil seal in you turbo real easy.

#1) do you have an inline oil restrictor? (you should have one)

#2) is your drain line large enough and as completely straight down as possible?

[Dickster223]

i have a oil resitor and my drain line is as straight as it could be
the smoke is coming from the exhaust not the turbo
thanks for all the ideas keep them coming

if you hade a seal go bad & oil went every where, you could have oil still laying in the cat or muffler,but it sounds to me that maybe your oil is bypassing your rings under pressure , i would do a compression check on my cyliders,if ok might be your valve seals .

Rebuilt turbo = no good, your probably still leaking.

[Dickster223]

there is no sign of the turbo leaking the intercooler pipes have stayed clean and the engine is a new one with about 3000 mile or so on it nay other ideas

its more then likely your turboo...

[dlx742]

98% chance ur seals r blown again, the white smoke out of the exhaust means oil, when ur idle try reving put ur hand behind the exhaust..do u feel oil? even then if not and u have lots of white smoke after start at idle ..selas r blown.....go to the person who rebuild it and tell them to do it right ..worst comes to worst get a new or bigger turbo : )

[playr158]

FYI

oil = blue/black smoke

coolant = white smoke

[celicast3sgte]

lol i was thinking the same thing about the smoke color... all these methods dont really show the symptoms 100% accuratly (the holding your hand at the exhaust and so on). If you really cant find whats causing the problems, you need to take the exhaust downpipe off the turbo and check for oil. Do this then come back to us with info, lets try this thing one step at a time so we can get it done fast and accuractly.

Quick and simple question that could solve all your woes. How is your PCV routed? It sounds dumb but I had the same problem and it's a simple fix.

[Dickster223]

i probably will be selling my turbo kit, I park my car for the winter and drive my 4-runner but gas prices are so high that i started driving my mothers car saturday and on monday on my way to eat after my 230 class some one ran a stop sign and i t-boned them. I am a little stiff and my g/f busted her nose and broke her hand. hopefully the other guys insurance will cover everything but i just dont have time to get the turbo up and running. how much could i get for it? I have everything
1. Garrett t25 with upgraded internals
2. two turbo manifolds
3. down pipe
4. pre tapped oil pan
5. brand new turbo xs bov
6. autometer boost/vac water temp nd oil pressure
7. intercooler and piping
8. etc

Hey man sorry to hear that......




I hope she will be alright ......your girlfriend too.


how much do you want for the BOV with the pipe.

[hitcachi]

Jesus man, trust me, i know how you feel. But with the amount of miles the engine had on it, if that is indeed accruate then ur problem was definitly blow seals. After turboing and having seals then new, ur have to let them seat, and "work in" But ne ways hope everything works out for ya.

Same thing happened to me...I tried everything. The 7A-FE has sky-high oil pressure. You have to make the oil return line just the right length and angle. The turbo cartridge has to be perfectly facing up and down, meaning the oil inlet exactly at 12 o' clock and the oil drain exactly at 6 o' clock. That'll help the extreme smoking, but your oil seal will start failing eventually and you're going to start smoking again, little by little. You need a restrictor for the oil inlet. That's my case right now. This Sunday when I get to P.R., I am installing the restrictor and rebuilding the turbo.
