Blue Smoke After Rebuild

[drewbird91]

Alright, I just got done with the rebuild, ross pistons, eagle rods, new 3g lifters, kept stock cams, head got a valve job, new valve seals, rebuilt turbo by PTE, and new external oil cooler with housing. The machine work was perfect, rings gapped to .018" by machine shop. I got the car primed and started and went to take it around to seat the piston rings and I went around the block and turned around. It looked like I had a crop duster. So I check some stuff over and took her for a drive and put 8 or so miles on it and it wasn't smoking as bad after that, but then it stalled on me and didn't want to idle, so I limpped back home. I have the gm maf set up "blow through", one of my ic pipes fell off, so I put that back on tonight, noticing it was oily inside, and took her for another spin. I couldn't even make it around the block she was pouring out blue smoke so bad. I also popped the plugs out (they were white) and looked down the hole to see that the pistons were pretty oily on top.

Some have said just drive the damn thing and if its still smoking after 100 miles then be worried. I think that the cylinders are getting so flooded with oil that its actually smothering the spark causing me to stall. Or I have some sort of vacuum leak, I need to adjust the wastegate because it is open at idle (correct me if I'm wrong, but that should be closed at idle). I was thinking it was the turbo, but that just got rebuilt, is it just because the rings aren't seated yet? Any insight is helpful.

compression test the car and get back to us.

Compression test showed 150-155 psi across the board. Remeber this engine is a rebuilt engine with only 10 miles on it. Let me know what you think.

I think I figured it out. It was my breather system. I had my pcv valve in there and a little in line filter coming off the pcv and side of the valve cover. The filter was dirty (never replaced it) and it wasn't set up right. So I put a RRE style catch can on there and started her up. She was still smoking, but not nearly as much. So it was just burning all that acess oil off that was still in the engine and system.

Now I was actually able to drive it. So last night I put another 25 miles on her. After I replaced the breather system she wasn't like a crop duster and I could actually drive it without smoking out the neighboorhood. This breather fix might be some other peoples problem also. I should have got that RRE style catch can a long time ago. Thanks for the help and ideas.
