Help! New Motor-turbo and oil coming form turbo!!

[Snoxracer]

Well I finally got my truck back together with my new motor form Scheid diesel. I picked it up the day after X-mas and installed it over the weekend. It has been completely gone thru. New pistons, 14mm head studs, main studs, street cam, bearings, port job, valve springs, ATS exhaust manifold, S-3 turbo, 80hp injectors, all thru Scheid Diesel. Anyway I have had it running twice, once last night, and once just tonight. Well when I first started it up the first night all went really good. It started right away, ran smooth and didn't miss a beat. I had it running for about 30 minutes, at around 1500-1600 rpm to break the cam in. I shut it off, checked for any leaks and such and found none.

Night TWO:

Well I had the trucked plugged in (block heater) for about 2 hours and started it up to put some heat in the motor to do the final torque on the head studs. It started fine and I was letting it idle for a few minutes, then I noticed a miss (pop out the exhaust) it would blow a puff of white smoke and it did this for about 5 minutes maybe a little more. Then it seemed to go away and idle normal. I thought that since the truck had been sitting for quite some time maybe the fuel was bad? So I started to remove the valve cover so I could retorque the head studs when I noticed a puddle of black oil under the truck. I can see that it has come from the exhaust side of the turbo, looks like it seeped thru the clamp from the turbo to the exhaust pipe or out of the waste gate. So my question is what is going on?? Is it fuel, injector messed up that was causing the miss? Oil seal in the turbo? Please any help would be great. It is making me sick to my stomach.



Thanks

Try checking the connector on the oil return line from the turbo to the engine.

Oil leaking from the turbo probably isn't a failed injector. I agree with amsoilman - check the return line plumbing. If that's good, then it could be the turbo oil seal (as you commented).



Turbo oil seal doesn't explain the miss though...

Thanks for the replys! I guess I shouldn't of said that it is oil,that it was a thick sootie oil-fuel and that it came from inside the exhaust. After I look a little I could see a drip at one of my exhaust clamps where it had run down the inside of the pipe and came out at the clamp. And as far as I can tell it came thru the clamp where the exhaust pipe meets the turbo. (thats were it formed a puddle). It wasn't leaking from the oil return tube, and it is not coming form the oil feed line to the turbo.

Well I finished the final torque on the head studs while the motor was hot and then check the valve lash, all the valves checked right on. I put the valve cover back on and then restarted the truck again. It ran perfect, it didn't miss once and I didn't notice anything coming from the turbo. So my guess is that I had a injector stick open or something and dumped too much fuel? Will this be ok? I will be calling Scheid in the morning and see what they say also, thanks for the help and input!!!!

It doesn't sound like a stuck injector to me, but I suppose anythings possible. Is it possible the low torque on the head coupled with higher-than-normal peak pressure permitted some sort of leakage at the head gasket? That would explain why things returned to normal when you retorqued the head.

It wasn't coming from the head gasket.

When we assemble an engine, on first and sometimes second startup we get a little assembly lube slobber out of the exhaust as it warms up and blows out. Also the miss and white smoke could be a little air working it's way out of the fuel system, or you could have an air leak in the system.

Supersonic, I think you hit it on the head, it only missed for a little bit, but what was werid was that I had already ran the truck for about 30 minutes in the shop and then it developed the miss. But it seems fine now, I have about 160miles on it now and it has missed a beat since.

Its admazing on how nervous I get when first starting my new motor, everything sounds different, yet everything is the same.

Well now I just have to get some miles on it to get it broke in and then see what is has!

i get that nervous feeling every time i start an engine i have done work on. . changed out cylinder packs, turbochargers, camshafts... but when it fires up nice and smooth, all is good

When I work on other people's equipment, I don't really get nervous. When I work on my own stuff, however...
