Hello,

I have been having a problem with my Turbonetics kit, I don't know if its a serious problem, but I want to post to see if it is common or not?

I did the turbonetics install on my car, and I have had no problems up untill now. I'm running with the turbonetics re-flash (I know it sucks), and I have been using 10w30 mobil 1 synthetic.

After I hit full boost (seems to happen more often in 3rd), and let off the gas the car shoots out a cloud of smoke. It only happens after I hit full boost, and the car does not do it at any other time. I don't think its the turbo seal problem because then I would be having smoke all the time. I can tell from the smell that it is burning oil. I didnt have this problem with the car when I first put the kit on, mabe it has somthing to do with the warmer weather?

What do you think could be causing this problem.

Oil line bent?
Using the wrong weight oil?

Its not my daily driver, so it has not been a great concern to me, but with the nicer weather I would like to start driving it again. Any help would be great, I will probably be dropping it off at a friends shop soon if I can't figure out the problem.

Thanks in advance!

 

Most likely related to the turbo oil return line... There are a ton of threads on this.

What sort of return are you running? Into the upper oil pan as per TN instructions? Into a spacer? How is it routed?

 

do you have a catch can ?

I have the same prob with my GT3076 on my SRT-4...

 

I do not have a catch can, and I do not have the oil return line going into a spacer.

Going to lift the car and see if there is any kinks in the lines.

 

i had this problem with my stillen lol

 

typical turbonetics turbo
its the blowby and if it gets too bad send it back and request a new turbo

 

There seems to be so many issues with these kits it's like u have to get lucky.. Good luck on rectifying this.. I for one will be following this just to see the outcome..

 

Not necessarily. There was just another thread where that stupid statement got made and the guy figured out he pinched the PCV vacuum line.

Check the oil return line and the crank case breather hose and make sure neither are pinched and that the oil line has no uphill routing..

 

I just actually got a problem similar to this fixed w the z. There really aren't a lot of issues with this kit as those might think. This is one of the most popular kits on the market for the stock z and I've talked to plenty that have had absolutely no problems. My problem was just a kink in the oil return line, replaced the line with betr quality (the original line was working to well and for whatever reason the line turned soft a mushy, causing it to clog and not flow correctly) and no more smoke

 

There's your problem right there... J/K

What color smoke? If its bluish white, then it is most likely oil. Clould be an oil drain issue and or oil level to high issue. Usually smoking on decel is a sign of oil getting past the seals in the turbo.

 

Where do you get your information from? Sounds like you're just talking out of your **** agian. Any turbo will have issues under the right (wrong) conditions.

To the OP - was the kit used?

 

just had this problem with my brand ne w kit i installed first check your pcv lines mainly the drivers side the line gets pinched i used the factory hose that comes otu of the valve cover as it is reinforced and get a 5/8 barb connector and run the supplied 5/8 hose From the TN kit from there on, seconed check your oil return line like everyone else is saying at low rpms the oil might be flowing good enough not to back up and leak threw the seals but at higher rpms the oil is flowing threw the turbo alot faster and alot more and the oil may not be flowing good enough then,

 

Surprisingly, I agree with Craig...

OT. Hows the tune comming? updates?

 

I thought it was normal that you get some white smoke after a hard pull because of the oil passing your seals.

 

Every car is going to give a puff of some kind between shifts, or a little here and there on decel.

A little smoke is nothing to worry about. If you have a space shuttle launch behind you...then yes...that is a problem.

 

Again?
i was just stating that most of the turbonetics turbos have blowby issues.

 

"most"

Your making blanket statements with no foundation in reality. I've seen you make these before and you really have no idea what your talking about. I've seen and heard of or seen every type of turbo having these issues, even Garret and OMGHKS.

The issue is with the mounting and included hardware, which is easy to get wrong. That paired with the fact that a higher percentage of these kits are self-installed means more issues posted on these forums.

 

Anyway, I would check the routing of the return line and also check your PCV ventilation to make sure the valve isn't bad or it's not kinked. Ultimately you might also want to do a leakdown test to verify you don't have a bad piston ring.

 

Okay everyone, thank you so much for all of the information, when it gets nicer out here I will look under the car to make sure the oil line is running on a straight, down-hill path.

Thanks again for the help and info, I will post back when/if I find the problem.

 

Okay, went to the shop today to get everything looked at, and the oil lines are not bent and are all downhill to the pan. The oil return was also tapped in the correct place.

He wants me to get a APS oil pan and re-route it to that to see if that changes anything. Also he said it might have something to do with the oil restrictor going into the turbo, he thinks the turbo may be getting more oil than it can handle.
