Oil Drain on your Turbo GQ

[beretta]

HI,

Just need some help from you if possible, I'm fitting up a turbo kit on my TD42 GQ. No intructions because its 2nd hand so I am after some info on where your oil drain goes from the bottom of your turbo back into the block. I've read on a lot of the kits they use a pre-existing drain back into the block so I wouldn't have to drill and tap the sump. Can anyone tell me where this existing drain is so I can use it?

Thanks for the help!

Cheers, Paul

The block has a casting that is machined, drilled and tapped at the factory when made, you'll have to make a return, some people drill and tap, some spike and tap some remove the sump and weld.

Thanks Joel, thought there must have been an option thats already there. I was looking at the hose going from the vacum pump on the back of the alternator back into the block? Whats that do?

[PGS 4WD]

The vacuum pump is supplied with engine oil and has a drain. Provided that the turbo drain can drop into this it would be fine, the turbo drain must be within 7 degrees of straight down or the incresed pressure on the oil return will cause the rear seal to fail.

Okay, I'll take a closer lookm at that as an option, thanks heaps for your help!

early td42 did not have the drain in the block, the drain goes in between 8th n 9th (from crank pully end) sump bolt about 40mm to centre of hole from flange, make sure the drain enters above the oil hight

Thanks for that nastytroll, that'll help heaps! Cheers, Paul

is it a high mount or low mount turbo
if it is a high mount you can use the existing drain for the vac pump but if is a low mount you need to put a hole in the sump for the drain

+ 11 for what the bloke above me has said.

Even then I have a highmount turbo and use the existing drain in the side of the engine - with the alternator draining into it as well - I find oil will bank up a little still.

Thanks guys, it's a low mount, so will be going into the side of the sump.

Thanks heaps for the help!
