Smoke out of Exhaust

[wingingmean]

I get smoke out of the exhaust here and there, So I have put a oil catch on, Changed the PCV valve, O2 Sensors and the Cat. I get a check engine light here and there for that.
The CE is on the front Bank. I'm thinking it could be the oil lines to and from the Turbo. Any help with this is greatly apprenticed.

Thanks

Most likely the turbo oil seal. How many miles on the car?

could it be the oil drain line gasket.

IMO, not likely. The gasket has aligning tabs to ensure proper installation. Plus, the problem would have been there all along.

So, 77k and you barely drive it. It had @60k when you got it(doesn't matter)? My front turbo oil seal start leaking @55k. I didn't know at the time that that was the problem. I figured that both turbos needed replacing. Had some smoke but, didn't use any oil between oil changes. I finally got around to replacing only the front turbo @89k. The rear is still OEM @116k.

Did yours smoke all the time. I've maybe put on 4k since ive owned it.

Did yours making a whining noise, or lost of power anything like that.

Did not smoke all the time. Mostly on deceleration. No noise. Ran normal. As I said, I drove it for +40k like that.

Did you change the front and the back PCV ?

I did the one on the back passenger side, there's one on the front to. I didn't realize that, where would it be located at.

 

[76FoMoCo]

Passenger side front valve cover

Passenger side front valve cover

I haven't, checking it when I get home from work. Would that really cause all those issues.

PCV or turbo oil seal.

I have a 2017 I use for work and it runs for 6+ hours a day stop and go with 10 minutes or so idle time at each stop. Once or twice a day at one of the stop it will smoke after the idle time at the drive off. I do over 20+ stops a day and some times it will go weeks between doing it. My thought...

Good info, if it is seriously think I will be pumped, I will get it ordered today thank you for the heads up

If you still have the old PCV valve you can save yourself a few dollars. Just gut the old PCV valve and install that on the front valve cover. It is virtually identical to the green fitting. This was a fix for cars that smoked after after idling for a while, like police cars. Hopefully, it will fix your problem. Otherwise I think you are looking at a turbo replacement.

Fingers crossed I dont need turbos, its on the horizon for down the road. Just not right now.

I'll also note that when my smoking problem started I replaced the PCV fitting with the green fitting in hopes that that was the problem. Of course, it wasn't the problem.

Fingers crossed mine was good today I replaced it with the old valve, I got on it pretty heavy. No smoke so far. I check the hose that goes from it to the intake no oil in it. I clean it when I changed them out last night. She had some oil in her

I replaced it with the old valve

I hope you mean that you removed the valve, spring and retainer from the old PCV valve and just used the external housing.

A few months ago I had an encounter with a fellow SHO owner. A stranger to me. He had some sort of problem with his dual catch can system. He had just replaced the PCV valve, on the front valve cover. I informed him that the PCV valve was on the rear cover and he now had two PCV valves which actually disabled the PCV system. I removed the guts of the new front PCV valve and sent him on his way.

Yes sir I did, I might not be the brightest crayon in the box, but I do have common sense lol.
