Hi Lowy44,

Here's what I was talking about.

These look like the ones you've got. Is the larger port the return and the smaller one the supply?

Hey Lowy44,

Yeah that's right mate the small one goes to the oil feed on top of the turbo housing and the larger one from the bottom.

Hope this is of help

nice work.. Just in the process of starting a t coversion

Yeah I put a turbo on my td42 and went for drilling and welding a pipe into my sump, would not opt for anything else. It's not that hard to remove your sump... The spot where you are thinking of drilling will proberly be a pressurised oil gallery so your going to blow your turbo.

Hey Diesel-Mate,

Would there be a problem using the take off points for the oil cooled alternator as I mentioned in my original post. If so, I would hate to give someone a bum steer.

What are your thoughts.

Your only trying to help :) Well you can use those returns as you mentioned but I wouldn't recommend it as you will have two devices draining from one tube so there is potential for a bottle neck occurance and a blown turbo. There are heaps of people running it like that without problems what so ever but I would prefere a vertical drain straight into the sump. A turbo only needs a mist spray of oil to work properly and a good drain so seals don't leak.

x 2 with me.

I got told to run it through the alternator too and a lot of turbo places do it but surely it would back up.

You want the oil to drain out fast and I ended up tapping a hole in the sump as well.

Hey mate in my original post I made the recommendation based on the fact I don't have the oil cooled alternator. If you dont have the oil cooled alternator would there be a problem using those take off points.

Yeah you could but I would be still going for a sump drain as you want the oil to drain from the turbo as fast as possible. You don't want any build up in the turbo. Also tapping of the alternator drain lug is only possible with a high mount turbo setup as a low mount turbo will have to force the oil up hill to the drain. Go for a sump drain as you won't have to worry about it.
