Fresh build leaks oil. Lots of oil. + other issues.
So I have an S5 turbo; goopy housings, atkins master kit, atkins rotor kit, RA classic seals + springs.
I just got the motor starting today. It won't idle, but that's probably from a vacuum leak. I just have the TMIC on with no clamps. (plan on running AWIC when the parts come in so I didn't bother)
Anyways, its run for about 5-10 mins total now. The front main, oil pan, + oil return line off the turbo all leak. There's probably puddle of oil under the turbo the size of a small cantaloup on the ground. I'd say 3-5". The oil pan is seeping. The front main is leaking down but not dripping off the motor yet.
Is this normal? I figure that maybe the oil pan is bent, + there may as well be a hole in the oil return line. But what about the front main?
Also, my BAC valve was making this odd noise when the car was keyed in the on position. I would unplug it then the noise would stop. Should I just ditch it? Or is there something bigger at fault here?

i don't know, normally i clean them up to a near chrome finish with 1000 grit. one seal failed shortly after assembly where i had put it on the wire wheel to clean it, the surface appeared smooth but apparently the seal still did not like it. so now if i ever touch the seal surface with any type of abrasive i feel it then needs to be nearly polished or it may give problems. also consider crankcase pressure, are the vents on the filler/center iron capped? the engine needs to breathe or it will start puking oil no matter what you do.

I took off the oil lines. One of the gaskets was only squishes half way around the outside of the bolt holes. Meaning the flange was bowed inwards. So I found another line, then wet sanded all the mating surfaces. Then a good coat of black rtv on both sides of the gasket and bam!
I ran her tonight - it was much better. It idled well. Until it warmed up, then it died. I noticed a lot of white smoke from the exhaust again. Am I right in thinking that there's a coolant leak somewhere when it warms up? I just have water in it right now - although there is a good amount of stuff in it from the heater core.
I'm gunna try and cap off the line from the t stat to the rear iron and see what that does. And I took the t stat out as well. Or I'll try my other throttle body.
Any other suggestions?

I won't be running it without the thermostat for long. Just to see if it's a leak in the throttle body somewhere or if it's elsewhere.
Now that I think about it more, there's nothing after the thermostat; just goes back to the radiator. So it probably is a leak in the throttle body somewhere. Gotta wait till I get home to do more tests.

Ended up capping off the coolant lines to the bac and unplugged it. Ran it without the tstat for a bit and it ran great. Put the tstat back in and ran fantastic again. But my coolant gauge is sticky - only moves up when I tap on the cluster. I'll pull that and get it to work. Same w the fuel gauge. It says it's full when I know it's not.
