smoke at idle. no bad turbo?good compresion? Solved!!!!!!!

[bezerk]

Before i want to do anything.
i did some driving today with the Syclone. everything has been installed, and runs pretty well. so i get back and let it idle for a while and see some blue smoke coming from the exhaust. i doubt it is a compression issue (almost new engine) and took the filler cap off and there is absolulty no blowby coming from there..
i have the feeling my turbo is doing this (idles at around 11.8-12.8 wbo2).
if i give it a bit more boost or spool the turbo up a bit it dissapears.

what is the easiest way to check this? without taking anything off?

Sounds like the same problem I was having with my turbo. It turned out to be an oil leak in the turbo. It was blowing oil into the motor. It was constant at idle but seemed to go away under power.

Make sure the oil drain line from the turbo isn't kinked or collapsed or anything. If thats restricted, oil will get forced past the seals.

how did you find out it was your turbo? or did you just took it off? i want to take it in for inpection monday, but i don't think they will love me big time with leaving them in the blue

about the return line, i'll check that stuff tomorrow. paid good attantion when installing it, but thinks might have got kinked doing other stuff.

to test this. could i block off the oil feed line, and keep the turbo from spinning by blocking off the pressure side of the turbo (just idling) and see if it does the same?

brand new ****ing turbo also

If this is a new engine its going to smoke until the rings are seated, especially if you let it sit at idle. You'll have to break her in...and that means hitting red line under load a couple of times. The rods are gonna stretch out a little too. You don't want to hit the top of the cylinder under WOT 10k from now on cylinders that haven't gotten some wear. The blue smoke will then go away. :2cents:

this engine has already had break in time. about 10k miles. so that isn't the problem.
i really suspect the turbo in this case. i can do a compression check. but 0 blow my from the filler cal/dipstick and valvecovers don't make me feel like that is the problem. also this engine came from Eric Rue his old truck. he took the heads off and inspected those also.

I have a Precision Turbo T-44 that needs a minor rebuild I will sell to you for $275 shipped if you are interested? I decided to keep the 20g on my SY. Let me know. Thanks.

Re: smoke at idle. bad turbo?

well. this is what i did this morning. at cold i have no problems, so i drove. got back, same problem, blue smoke. disconnected the PVC system, same thing.
that i took my throttle body hose off to check for oil and dirt. it was super clean.
after that i thought what the hell. let's do a compression check. in about 20 min. i have 150PSI on al 6 cilinders. and the sparkplugs were super white. and really clean. (if it was burning oil they would have been black, right?)
so everything put together, i checked out the exhaust housing. took the upper downpipe off and it was just not looking oily. let it run that way for 10 min. and didn't leaked oil.
i am stumped. 2 hours later i found out i have a good turbo. an nice Engine with good compression. but i still have this damn blue smoke when warm at idle.

the next thing i will try is to put the T back in the PVC system and put an breather vale at the other side of the T.
any more suggestions i would be glad to hear them cause i am out of geusses

well, i did the PVC valve thing, same results, got some light smoke coming from the valvecovers as the well. do you think it can be the valve seals going bad? this engine hasn't ran for about 3 years. can they dry out that fast?

That was the problem on Barry's Sy about a year or so ago. He changed out the valve seals and it fixed the problem. For as easy as it is to do in the truck I'd say go for it. Plus, even though Eric checked them out, they were still used and doesn't mean they could have worn a bit after the first few hundred to thousand miles YOU drove it.

drove it for about 10 miles. maybe they dried out after sitting for 3 years. don't. i can't think of anything else that will cause a bit of smoke out of the covers, and blue smoke in general if the compression is all good (tested them after about 20 min the truck had runs (so warm) if the pvc ain't the problem and the turbo is good...

damn moey pits:rotf:

is does run like a raped ape though. so much faster than the build Ty i have.

well, thinking about driving 120 miles tomorrow for inspection/plates.
got oil pressure. no external leaks. clean oil clean sparkplugs. and it runs.
maybe it will go away. will keep you posted

It kept blowing the upper intercooler away from the throttle body and every time I checked it was oily. I traced it back from there. Finally yanked it out of there but haven't gotten it replaced or rebuilt yet.

Re: smoke at idle. no bad turbo?good compresion? Solved!!!!!!!

Ok, i think i solved the issue.
things i did further. aplly pressure on lower intake to check for leaks.. none.
check pcv system..good
still suspected my turbo, so i went trough my pile off nipples, and had the feeling that is was working like some kind of aftre burner. and found a restrictor in there that i got with my turbo. altough PTE said it wasn't nescecerry to run that restrictor i still had the feeling i should atleast try it. altough the nipple didn't feed my feed line, a made a restrictor in the nipple i was using,
put thread inside of nipple M5. get a M5 adjusting bolt. install it. and drill a 1 mm hole.
went out for a test drive. took it back no more blue smoke!!

now i only need to check teh alternator since it was giving me problems this morning, thanks!
