I would think the pan would be the best place, little time to cool down, not overflowing the oil passages of the engine from the covers down.

The engine I am considering must have a little blowby because there is some oil that comes out of the vent line in the valve cover. I am thinking if I dump the turbo oil in the cover, it will go out the vent line???

Any ideas/opinions.

The pan is thin steel and the only way to put a drain in it is to pull the engine and the pan and weld on a bung. Not enough room to do it on the vehicle and dont want metal chips in the pan from drilling.

This is one other plate on the engine I could tap and dump into, but is way away from where I want to put the turbo.

 

youve got a 2wd, you wont have to pull the motor to take off the pan. You may have to lift it up slightly though.

 

With both my Vortech supercharger and my older journal bearing turbo, I returned to the valve cover. The ball bearing turbo wouldn't take that so now I return to the pan.

 

If you're talking about the stock oil pan, it's aluminum, and it's thick enough that you can drill and tap it without needing a bung. If you do it into the pan, make sure that the return line is ABOVE the oil level in the pan.

 

can we get some pics of peoples oil returns? i need to know this too. where in the oil pan is best. i understand above oil line. but where? toward the front or back or what?

 

I Didnt Like Running The Oil Return(s) To The Pan On My Big Block Twin Turbo... I Had Problems With The Oil Backing Up In The Outlet And I Had A Seal Fail... But Once I Moved It Higher It Did Really Good... Then Again I Guess Each Combo Is Different... Then Again The Outlet Fitting On The Turbo Was Above The Valve Covers So It Was "not" Going Uphill To Get The Oil Out.... Some Of You With Your Setups May Run Into Something Similar

 

What happend when the seal failed? Did it burn up, or just pass oil?

 

OIL PRESSURE DROPPED BY ALMOST HALF... AND GOT A BAD TAP... AND SMOKED LIKE A STEAM LOCOMOTIVE


OTHERWISE BESIDES SOME MAJOR CLEANING.... IT WAS OK... NOTHING PERMANENT

 

OH YEAH... IT IS A DRAG CAR SO I DIDNT RUN IT LONG ENOUGH TO DO MAJOR DAMAGE... BUT IM SURE I COULD HAVE

 

This is not for my truck...some might remember the little turbo I have for my tractor, its for that project.

The oil pan is held on with probably 15 10-32 or 1/4" screws and only can be removed if the engine is pulled. It is thin sheetmetal.

Thanks
