Head To Sump Oil Return

[vspec_gtr32]

as tittle says, been trying to find some pic's of how it's done..

i know the head is drilled and tapped and a fitting is put in then a return line is fitted and another hole is drilled and tapped to the sump..

where exactly is this done on the head...eg front, left side, right side, back ect..

where exactly is this done on the sump... front, rear ect...

any one got any pics to show us???

Any help much appreciated

hey man, from what i can tell it goes from the top welsh plug at the back of the engine, and down to the sump (un sure where) it goes under the plenum side so im guessing anywhere really aslong as its higher than all the oil so it works well,

got a pic, i took it from the oil control thread on this forum, may be some more pictures? would be worth a look?

Where do people get the fitting on the back of the head pictured there, or are they fabricated?

Thanks bubba, but I was talking about the alloy fitting screwed into the back of the head

ENZED for the fittings, mine is a 1" BSP 90deg elbow.

heaps of people just fabricate a fitting to do the job. the return is then plumbed back into the sump on the plenum side becasue of the way the crank turns it helps to promote flow into the sump and not get sloshed back up from the crank.

not required...they dont drain anything substancial...they actually vent the sump on big clearanced race engines. On a properly built street engine they are waste of money, time and damage to firewall.

Notice two fuel rails on the picture supplied in post #2 (it was from another thread that i posted this picture in) Its a big $$ big clearanced racing engine.

And IMO, they're shit.

I have one on my R33... There is NO CHANCE you can ever fit the 90 degree bend whilst the head is in place, without unbolting the engine mounts and lowering the engine.

Once you have it on, it sits in the way of the heat hoses, and then, still sits hard against the firewall.

If I had my time again, I wouldn't do it.

Forgot to mention, I'm only running the dash 8... No idea how the people with Dash 10s fitted theirs!

couldnt agree more.. sure there cheap.. but not suited at all.. the ones from spool are a much better option!
