Re: redrive oil return, was Re: New Cooling
Setup
Hey, Steve....thanks for the
pictures. Since I already have the aluminum plate covering the oil
metering pump, it would be easy to drill and tap that. After hearing
what Rusty had to say, I'm not sure if I might be better off leaving it as
is.....Need to ponder this one. Thanks for taking the time to share your
pictures, and I hope your cooling temps get under control so you can just go
fly and enjoy the fruits of your labor. Paul Conner, 13b powered

Hi, Rusty....My
13b has an aluminum plate covering the old injection pump location. Do I
just drill and tap for an NPT fitting in the plate covering the old
pump?
Ooops, I just remembered that I'm
actually returning to the turbo oil drain location on the front cover,
and not the injector pump location. When I took the turbo off, I
just made an aluminum cover plate with a hole tapped for 1/4"
NPT.
You don't
by chance have an old picture lying around that shows your plate and/or
fitting going into the engine do you?
Amazingly, I don't have a picture that
shows it.
My return
line presently goes to the oil pan, but to drain the oil, I have to first
remove the PSRU drain line. It would be better to run it to the oil oil
injection location. Thanks for the info. Paul

I
ran my oil drain to the oil pan plug location on the original
engine. This violates the rule of returning oil below the level of oil
in the pan, but it worked fine. Having to remove the PSRU drain line
to drain the oil was the best part of that system. I left the line
free, so I could remove it at the redrive, then lower it toward my catch pan
to drain the oil. It was totally mess-free. I miss that now,
especially when I have to drain a little oil to make up for the pre-mix
scavenging.
