I was driving on the highway and decided to mash the gas a little on the highway but not too hard ...I noticed white smoke out the exhaust very visible.....any ideas?? I have Turbonetics but dont think I even boosted past 5lbs or got the RPM's past 5K I guess its possible my tires may have spun but not likely..... EGT A/F were all good nothing Lean or Temps too high...I usally never boost cause I live in Hawaii and there is no race track and I drive only 2 miles to work..temperature today was 90 degrees

White is water right? I may be worried over nothing...hmmmm

 

Sounds like a blown head gasket

 

If it is how do u check?

 

Actually it sounds more like a turbo seal. If you can pull the turbo off see if there is oil in the turbine side. I'm thinking seal.

 

sounds like a turbo seal to me? if it is not that check your oil for milky film if there is then head gasket.

 

when the car cools im gonna check the coolant lvl..I installed this kit in october and only have put 5,000 miles on the car I live 2 miles from work so I hardly ever boost......odd....

 

Could just be the turbo seal. If the car is running 100% normal no misfires or anything I'd start by checking the seal

 

what the procedure for getting this fixed MIA?

 

I'm on my 3rd turbo due to oil seals. Send that turbo back to Reggie @ TN.

They will send you another one... no questions asked.

Man, that's almost unbelievable to me. Have people with blown seals all been using tapped oil pan spacers or is there any logical reason for this?

 

Taurran, what are you using for an oil source then?

 

Stock lower pan and a tapped upper pan. I'm going to be installing the JWT spacer soon but will not be tapping it.

 

yea I took the coolant cap off and I see green coolant still...I dont feel like taking the turbo out tonight cause thats an involved task at night...I guess well c 2 morrow

 

So have you checked your oil lines to/from the turbo to see if it is kinked or damaged in any way? Are you running on a tapped upper oil pan or do you have a tapped spacer?

 

steel line looks fine...tapped spacer...havent gotten under yet...

what ya thinking..the return line is under pressure and could blow out the seal???

 

After I first had my turbo installed, I had a major oil leak on my oil return line when it melted against some piping. We went back and replaced that line with some high quality steel braided tubing that is much better quality with the stuff in the kit. Upon looking at the return line, I noticed that it was also slightly kinked due to being cut too long, which also might have been an issue in the long run. The new line we used was much thinker and more durable than the old one and shouldn't have issues with kinking up.

One thing I have noticed is that it seems people with oil returns tapped into oil pan spacers seem to be having issues with more blown turbo seals. So far, I can't remember anyone that has tapped the upper pan having the issue. Generally, when it comes to tapping the oil return, the higher you tap the better. This assists in circulation as gravity will carry the oil out of the return line back into the lower pan. If you tap into the spacer, you will actually be returning oil into standing oil, which can hurt circulation. It may only be coincidence, or it might actually contribute to these issues.

Either way, blowing a turbo seal is either an unlikely factory defect, or more likely an issue in the setup of the oil return or sender. In JetPilot's case, having two turbos with blown seals seems to point to an issue with the configuration or install. The chance of getting two bad turbos with the exact same issue is highly unlikely.

 

Old rule of thumb is, Blue Smoke--Oil,,,Black Smoke--Fuel,,, White Smoke--Water. Wheather that still applies ,, I dont know. If its a seal, what causes this? Heat ? Pressure?

 

After removing the second turbo I did notice there was a lot of play in the shaft. I didn't check the shaft before installing the turbo.

I don't think I will be re-installing the AAM oil pan spacer.

I'm not necessarily saying that it will cause problems, only that it could very well contribute to less than optimum flow of cool oil to the turbo. It would be interesting though to get a count of how many people have blown seals using a tapped spacer.

I personally think the way to go is with a higher volume oil pan or spacer (PE or APS pans are best), and a tapped upper pan. I know it sucks to tap the block but it is the most efficient spot to do it.

 

I'm pretty sure the answer would be a combination of both.
