2G High Idle, White/Blue Smoke?

[import2gtuner]

Sorry if this has been covered but I can't find my situation in the forums. My car sat for a good 6 months without starting due to a front subframe job that went alot longer than expected. Also had a battery issue. After the 6 months got the car started up and everything was good. Ran perfect.

A couple weeks ago it started leaking oil from the return line off the turbo and realized the bolts forgot to be tightened. Upon tightening one of the bolts broke off. So had to pull the turbo off and take it to a machine shop to get the bolt out.

Now present day the turbo is back in (stock btw) and I fired it up and it idles at 2000rpm then drops to 1400/1500 and fluctuates there once it warms up. Also blows white smoke out the exhaust but can see blue sometimes in it. Other than that it doesn't overheat and oil pressure is normal.

I just can't win with this car, I just want to be able to pull it out of the driveway again. Trying to do everything right and just when I thought I was home free putting the turbo back on this happens.

Any help would be greatly appreciated I just want my car back

Do you have an aftermarket oil press gauge or just the stock one?

 

[import2gtuner]

I'm going off the stock one, I do have an aftermarket one it's just not hooked up.

In mine it smoked like crazy because of blow by. The stock gauge was reading normal while my AEM one was at 140psi. (i have a 16g turbo)

Could this really be happening already? It only has 79K original miles. I guess I could do a compression test. Could a head gasket cause this as well?

 

[605jdm]

mine had 170,000 miles and compression came up normal. Is it stock boost? i had 18psi

 

[605jdm]

can you drive it still? does your dipstick pop up hitting boost

 

[import2gtuner]

Yes stock turbo (t25) it's a 96 gst. Only things I have aftermarket are a fmic, bov, exhaust system, exhaust manifold, intake and suspension.

It still boosts sitting still I'm afraid to drive it because of this issue now

how thick is the smoke at idle? also i would tune your idle back to 750rpm

 

[import2gtuner]

At idle not crazy thick but you can clearly tell it's smoking. Revving it up makes it worse.

 

[605jdm]

i put some stop-leak plus no smoke in mine and it worked as a band-aid until a rebuild. Your problem sounds just like mine was.

If it is mostly at idle only and goes away when you drive off, it may be valve stem seals.

Otherwise turbo could be pushing oil, or oil is getting past the rings, or head gasket.

 

[605jdm]

You should hook up your oil press gauge then check psi and make sure its not blowby, could be bad turbo. Also kind of stupid thing but make sure you dont have too much oil.

 

[import2gtuner]

Either way I guess it's not good I will wire that gauge in and see what it says, do a compression test/leak down test and go from there.

before all that check your oil level make sure its in-between the 2 hole, overfilling will cause it to smoke also.
