At the end of my line...frustrated! blue smoke.....

[cmgreen]

Let me ask this. If its not the turbo, and its not the intake seals, and a oil catch can was installed to catch blow by from the piston rings then what else could be causing this blue smoke issue?

 

[Phoneguy]

Has engine been run at 190° or better...like phoneguy said...temp, rpm and some boost (and some miles) will help break in.....i use old dino oil during break in....
Oil pressure no too high?

Dont listen to phoneguy...his car dont run.......LOL.

Oh my apologies. Dam it. Gotta reread some of the basics.

When does it smoke the most? At idle?

Start it up let it smoke up real good then pull the plugs. Snap a couple pics of them and post back.

. Does your felpro intake gasket have the factory valley pan to shield the pcv from oil? If you pull the plenum off is there oil in the intake? How is the compressor side of the turbo dry or signs of oil?

I know you said it was just rebuilt but that does not mean a ring or two was damaged during installation or possibly clocked wrong....or a crappy set of rings.

I did not see you post anything about doing a compression test....again just because it is a fresh build do not rule out some basic items like that. Also I have seen stock replacement valve stem seals look to be in good shape and on correctly but still smoke. I use a nylon comp valve stem seal with the little metal tension rings that work great.....however if you saw the car smokes real bad I would first be pointing at other large items.....

To follow up behind Turboburick.........does it smoke mostly at idles or acceleration or both?

At idle is when I get the steady, constant stream of blue smoke. I will take pics of the plugs later this evening.

Yes, I inspected and reinstalled the valley pan when I installed the valve seals. I haven't pulled the plenum to inspect. I will try to do that today. To be honest, I didn't pull the compressor side of the turbo. I will check today tho..

Drive it and dont worry about it

Hey Amelio, That's interesting you say that about the seals because reading other post and going by my "gut feeling" (if that count for anything) I just feel its those felpro seals. I have seen other makes/model cars with valve seal issues and my national smoke the same way.

Sorry BJ, I cant do that. A smoking car just do something to me mentally! LOL

Is it possible I may have two issues here! At idle I get a constant blue smoke, the blue clears a little when I rev the engine and then puffs white smoke when I let off the pedal....Moisture dripping from exhaust.

Definitely check compression. Did you get a chance to check out the compressor side of the turbo?

You need to drop everything, stop fishing and do some actual diagnostics. Speculation just makes you spend money replacing parts that don't need replacing.

If you have access to these tools, do the following..... Compression test and a leak down test. If you don't have the tool, won't get them, or just don't feel like running diagnostics....

Since you have a steady stream of oil smoke at idle. Try this... while the cars as warm as you can stand it, put a brand new set of NGK plugs in. Let it idle ONLY (or only do things where it smokes profusely). After 30 minutes or so, kill it and pull the plugs. Look for consistency across the plugs carbon-wise or one oddball that's glossy black.


also, fire your trusted mechanic and the machine shop.

Compression Test results: cylinder#1- 145

cylinder#2- 136
cylinder#4- 136
cylinder#6- 140
Pulled the plugs. Best I could do with cell phone camera.


Plugs facing other direction

Intake/Compressor side of the turbo. pic. too is needed.

I hate Champion plugs excepting in certain lawnmowers.

Delco AC 43's gapped at .032"-.034".

#6 isn't looking too good.

pics of the exhaust side after idling and light revving for 45 minutes.

bone dry

pics of intake side

same here!

Turbo drain line flowing freely? Probably so given that both sides appear clean. You may not be able to 100% tell whether the turbo seal is gone without pulling the housings.
Any play in the wheel?

I'll tell you that a few months back, mine was doing the EXACT same thing as yours - blue smoke at idle; looked like some whitish smoke with light revving. Had lots of in/out shaft play. The smart guys on here all told me it was the turbo. I didn't believe any of them, but still took their advice and got a "new" stock turbo from bison. Even when I removed the turbo, I STILL didn't believe the turbo was bad; there was no coking on the exhaust side. I FINALLY believed them when I put the new turbo on and "poof" - NO SMOKE!!

 

[earlbrown]

what does the inside of the elbow look like? The exhaust blades run hot enough to keep themselves pretty clean.


also, what weight oil do you run and how many miles are on the turbo?

 

[trixdout]

Check around the hot side of the turbo where it mates to the center parts of the turbo that the oil feed goes to and drains from. Check around those 6 bolts and see if there is any black glazed oil there.
