Head To Sump Oil Return

[shy_s6]

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.

so n1 pump, tomei oil restricter, 8ltr sump with baffle is enough?

if i remember correctly

you just enlarge the stock oil returns

i used to run N1 pump, tomei restrictor and stock sump with Tomei baffle 1 litre over filled.

never had an oil control problem and bearings were as good as new on pulldown after 3 years of racing.

Be specific Paul. "racing" Drag racing or circuit racing. Both disciplines require minute attention to the oiling system but curcuit racing adds other factors over and above what 1/4 mile work has to deal with.

Opinion is divided as to wether the drain back is a worthwhile mod or just a waste of time. The only definite in this whole debate is that it certainly wont do any harm by being there.

With that in mind I am more than happy to use it just on suspicion. It costs bugger all in the grand scheme of a build and, If the pro's are right it may save an engine.

Good enough for me.

great point for so little that extra insurance of doing it maybe worth it.

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

That is exactly what I was talking about.
