Turbo oilline setup???

Sorry im so ignorant about turbos. Hopefully only one last question. I need to know if the turbo will pickup oil all by itself or will i have to install the pickup line into a pressurized port in the motor. Thank you.

Have to run a pressure line to it, and a drain line away from it.

Many connections on a turbo.

Pretty much, the turbo will not suck up the oil on it's own.

To enphasize what was suggested, yes, you need pressurized oil, but you also need to remove the oil from the turbo, and it requires a lot of attention. If you are using gravity drain (turbo is higher than the oil pan) you must use a large drain hose, with no odd bends, turns, angles and keep it as free flowing as possible. If you are not careful about this, the oil will back up and run into the turbine/compressor housings, causing the car to smoke like a banshee.

If the turbo is below/same level as the oil pan, you will have to use a pump to scavenge the turbo oil back to the engine, or you will get teh same results as above.

Ha, you just gave me the way to fix my truck with the turbos mounted on too much of an angle. I never thought of a scavenge pump. Wonder why none of my freinds ever suggested it? Oh well, thanks for that, no more smoking, restricted oil lines, and worn out turbos. I may actually re-install them.

Bob, maybe you can help me with info. I remember the max angle of the turbo shaft being 15 deg slope. Mine were a bit more angled than that. Do you think that with a scavange pump a turbo could be mounted on a much more of an angle?

maybe....can't say I've ever experimented with that. If it was a positive displacement scavenge pump that was very carefully sized/restriced to get the right ratio.....you could probably mount the turbo upside down if you wanted to.....but knowing that you have the right ratio is rather difficult

I'm almost afraid to ask why you "had" to mount it like that.....

It was just easier for clearance and plumbing, I didn't know at the time the shafts had to be on a more level plane. Thier not too bad really maybe about 25 deg angled towards the exhaust outlet and they smoked and wore out after I restricted the oil going into them (to get rid of the smoking) I found out later they should be level, I should've known. Using a scavenge will keep me from having to hack the flanges off the exhaust manifold and then haveing to replumb every connection on the trubo.

if it was me, I'd just fix the angle issue. Would cost a lot less. scavenge pumps ain't cheap. Adds complexity to the system that isn't necessary. If the pump fails on you, you can't drive the car.....something to think about.

Ok, thanks. I think the set-up may just set under the bench until I get the ambition to cut and reweld flanges and remount everything. Using nat aspiration is hard after being boosted for many years,,
