You don't want a vacuum on the drain. You want it gravity drained to a sump and then pumped out. Doesn't have to be anything fancy. Steel pipe end caps work well. Bigger the sump the better. Venting it also helps.

Buy a proper pump.

so the way i have it now is that it drains right into the oil pump, and the pump goes straight to the oil filler neck, but your saying thats not good since its sucking the oil from the turbo , that i should instead have it drain into a canister than have the pump suck it from the canister

stevieturbo

If it was sucking oil from the turbo, you wouldnt be having problems with oil pissing out the rear of the turbo.

If you had a proper pump, what you have would work.

But yes, if you can gravity drain into a reservoir and then scavenge from that, that is a good option. But if your scavenge pump inst up to the job in hand with either configuration, the problem is still the pump.

Ideally, yes. Not all do it that way, and depending on what pump you use and the line diameter/length.. etc some get away without. Putting suction on the drain can pull exhaust gasses and other soot and crap past the seals. This is why when you see low mount OEM turbo setups they have a sump of some sort with a vent. This also allows some a place for oil to gravity drain when the system is shut off. Some use timers so the pump continues to run a minute or so after the engine is shut down, or just leave the pump on a bit after engine shut down.

well i have it about 2 feet from the turbo

but i do like the idea of the sump and just might do it since all i need is a canister

Oddly when I vented mine, the turbos smoked like ****.

When I sealed them up all perfect.

Can't argue with success. Strange though, that doesn't make any sense to me. All the OEM and most aftermarket porsche stuff is vented.

stevieturbo

It didnt make sense, but it happened. Tried it several times.

Although given space, I do not have room for proper large reservoirs like the above, so no doubt that was part of the problem
