Does the oil return line point straight down?

I'm in the process of getting everything ready to do a 'not quite but almost' GReddy kit on the car.....Does the oil return line have to point straight down, or will oil pressure in and the height of the turbo above the sump still ensure that the oil drains back ok?????

turbored

the greddy return isn't straight down, that being said, you need every part of the hose lower than the previous to prevent pooling.

It doesnt have to be straight down but pretty close to it. I mean with in like 10 deg.

Downhill. The original FM turbo kit drained down and around to the oil filter side of the block. If the return ever straightened out any the oil didn't drain properly and caused some smoking turbos from the oil foaming from not draining. That's why FM went to the straight down, drilled oil pan method.

The oil gets pumped in, but gravity is what's going to drain it. Above post says 10 degrees, I was going to say 15 degrees max. point is, get it as straight as possible.

I'd just say anywhere between vertical and horizontal.

Thanks all - looks like my TDO4 needs to be clocked by 180 degrees prior to fitment (I think it came off a bottom mount fitment, and the previous owner had bought it to be an over the top fitment, but hadn't noticed that it was out due to having sourced parts but not mock fitted them).

I found a website yesterday which basically backs up what's been said here.

Anyone here clocked a TDO4? It looks to be a relatively easy job - remove locking ring, pull apart, realign and reassemble.....

Any tricks or tips for young players?

Exactly. Good. Simple and easy really.

That's if the turbo isn't seized beyond belief and refuses to even acknowledge the fact you're trying to do something here, leading you to spray an entire can of PB blaster on it to no avail, so you bolt the turbo down, buy a cheap torch that's too small, use it anyway to heat the hotside while beating the hell out of the leverage bolt in the other side with a rubber mallet which of course does nothing, leading you to use a different turbo on your setup because how much you hate this one now ..DIE TURBO DIE!!!!

Yeah, you should be fine.

My drain is like at a 25* angle and its been fine for about 2 years or so. I would say get it as straight as possible but like I said, I have been fine with mine.

My drain left the turbo at a 45 degree angle. I never had any issues at all.

45 degrees? (!) Holy ish. I get the feeling you could make it drain upside down

But, hey, if it doesn't send out a smoke screen I guess you're fine.

Most drains gently slope off the turbo. I see no problem with that. As long as the CHRA itself is vertical -+10°.

Better than the 1-3° of the stock greddy return line.
