Oil Return Question?
Ive attached the Turbo, and ordered by silicon elbows, all i need now is some 50mm steel / ali tube, and a 60mm air filter (Might be abole to modify
OEM for starters).
I plumbed in the oil feed pipe after removing the plug which plugs the hole normally on the 2.0t block, but the return hole is blank.
Question is;
Can i put the oil return to the top of the engine via the breather in the rocker cover, or will this volume of oil cause me a problem?
 
TURBO'D!!!

Do you have an oil cooler fitted?
If so, could you "T" the return into the inlet of the cooler?
Either that or straight back into the sump?

The oil return must be lower than the turbo oil outlet, so the answer in this case is no.

Wot MikeRJ says ^^ but also check that return hose is suitable for the extreme heat found in the turbo area.
Blew an engine on one of my Thema Turbos as a result of the pipe close to the turbo being "cooked" - not a cheap option and with a bit of
preventive maintenance shouldn't have happened especially as the local "specialist" had just serviced it - but that's a whole
different story!!
Cheers, Pewe

as stated return must be lower than the centre of the turbo, you must gravity feed it back to the sump, or use a scavenge pump to help. You cant
plumb into an oil cooler line if its under pressure which they usually are.
Best bet would be to remove the sump and weld/fit a tail to so that you can attach some kind of pipe, but as also stated above, protect the top part
from the heat of the exhaust housing of the turbo.

Thanks Guys,
The return hose is of a steel convoluted type (Proper job from a renault engine) so all i need to do is whip off the sump and weld a return nipple
into it.
I need to take the sump off anyway, to replace or repair the oil pump. 
Thanks fellas.
Oh, theres no oil cooler as yet, but i might fit one as i have a sandwich plate and a spare remote housing.
Kindest Regards,
Richard.
