By-pass oil filter?

[ronmarabito2002]

No problem with your supply point Mike. Just make sure you have an
unrestricted return to the pan. If you connect to the bulk oil fill
line, you will have a problem pressure reversing your filters when you
go to put oil in the engine. Possibly inserting a check valve, you
could get away with it.

There might be a port on the engine similar to the dipstick location
that would allow you to dump into the pan. There was on the 6V92.
Ask Ernie, because I had one on that engine.
