Tracy should confirm this but I think you want your oil return to enter the pan above the oil level in the pan. Otherwise you risk oil backing up in the redrive. You also risk pressurizing the drive and possibly blowing a seal. I know in turbo installs this is true and a return line into the pan below oil level is a definite no-no.

 

I’ll let Tracy speak up if he thinks this will be a problem.  I just can’t see it as an issue with the redrive.  It’s still a gravity feed, and there isn’t any pressure.  Turbo return is somewhat different.  As I understand, they always use those large diameter pipes, because the oil gets beaten into a frothy foam by the extreme RPM of the shaft.  I have a stock oil return pipe on the way from Mazda, and it would bolt right on, except that something from the mount will surely be in the way.  I may have to cut the pipe and reconnect it with some hose.  We’ll see.  Who knows, something has to fit eventually :-)

 

BTW Mike, I’ve been thinking about you today since I’m working on my cowl.  Mine is going to be uuuuuuugly.  Van is probably having nightmares now, and doesn’t even know why yet :-)

 

Cheers,
