on idle very little smoke.......
rev it on neutral...still very litttle smoke


regular driving out of boost it doesnt smoke(car still hasnt hit boost) but when i stop at a light or let off the gas it puffs a huge cloud of smoke.....bluish/white(oil)


setup is an lsvtec new pistons/rings...new valve seals new valve job...new sc61 turbo with toyosupr manifold.....im guessing those are the 3 things it can be...its a new build with 200 miles......any advice?????

i thought it was a crimped oil return but its perfect and the feed is a -4 with a greddy oil filter sandwich

 

Its either the oil return or just a bad oil seal on the turbo.

 

Bullseye. When mine did this it was because of a constrictive drain line.

Blown turbo seals will do this when you deccelerate. I've seen it a LOT on turbo cars, stock or moddified, when they do it on deceleartion only the seals have usually gone

i agree

 

On my first turbo set-up my oil feed line was too big, and my car smoked like that. I ordered a new one from Stan and have never had the problem again

It also could have too much oil in it &lt; - - - - Just a thought

 

My buddy had that with his Edelbrock turbo kit. Worked on the oil drain line for a while and finally just sent the turbo back. Garrett inspected it and found the oil seals were bad in the turbo and he got a new turbo.

 

when u downgraded oil feeds did u go from what to what....-4 to -3????

Yes -4 to-3An

 

how bad did it smoke b4/ after...i know someone that told me i can use a nos jet to restrict flow of oil feed......and i know someone who told me to disconnec the feed and run the car a little to check if it still smokes........i wanted to race this weekend at moros and wanna see if thats it....im hoping it isnt oil seals.....


all my friends on boost have -4 w/o a problem.......so i dont see why this would happen

I have no clue, but this is the first thing I changed out and it fixed the problem ?

 

You say you have done the valve stem seals? are they located properly?

 

new seals.....new valve job...pistons/rings/...head gasket..........all new even the sc61 is new......oil return is at a 45 degree angle...and a -10 unrestricted.....no crimps...


the feed is like i said a -4 that comes into the turbo at a 90 degree........i might downgrade to a -3 and see what happens...i hope its that pray 4 me....lol!

 

bump

 

Same thing was happening to me, thought it was a valve seal and it was the turbo instead.

 

That's not good. I have a very light smoke while decelerating. The "s" shaped return probably isn't helping those turbo seals though .

Phil

 

I'm thinking it's the turbo also Damian.. isn't that the one you said you borrowed from Yuyu that you thought might be bad anyways?

 

my old 50 trim t3 tended to smoke on decel even with a -3an feed. So I made a restrictor out of an 1/8"NPT alen head plug that I tapped into the bottom of my feed fitting on the turbo. worked great.

 

more help please

How much more help do you need. Your question has been answered. Inpspect your oil return line, fix it if it looks somewhat kinked, then tell us if it's still doing it. Would you like one of us to come to your house and adjust your return line??

Your rings may not even be seated yet. I'd wait a little while longer and see if it goes away. Does is smoke worse when your in boost?

 

I have the exact same symptoms, it is my turbo seals for sure. Bought a rebuild kit which I am putting on next week should take care of the problem.

 

car hasnt hit boost at least over 1 psi.........after 250 miles it shouldnt smoke at all......

Those rings are long seated.
