Re: [AMC-list] Too Much Oil

["masheen" <masheen@xxxxxxx>]

A trick I used to restrict the amount of oil going to the heads was to 
fabricate a plug to fit the oil passage supply hole.  A 3/32" (.094) hole 
drilled through the center of the plug worked fine.  The plug doesn't need 
to be very long and can be removed if need be.

I think I'm going to put a piece of wire in the oil line to the head and try 
to
block about half of the flow. I'll also look for an appropriate smaller size
fitting. I think my oil lines are 1/8 inch lines. They might be 3/16 though.

The 65 models actually had a solution. The oil line comes off the flat side 
of
the block near the front, not off the main oil gallery. The 90 taps into the
front cam bearing shell, which has a hole in it to feed the head. The front 
cam
journal has a slot cut in it about 1/3 of the way around. Oil only fed to 
the
head 1/3 of a revolution of the cam. So restricting oil flow by compressing
(flattening) the line or something like that should work.

Pre 65 models (the change occurred late in 64, actually) have a single line 
with
a T in the head. The line feeds from the main oil gallery (the "hump" down 
the
right side near the bottom of the block) to the T. The T is hollow and feeds 
the
head then the oil filter. Once pressurized you get as much flow in the head 
as
if there were no T though. A smaller line would work also. I seem to recall 
that
is a 1/8" line. Dropping to a 1/18" might be too much though. A couple 
adapters
would do it. If it's a 3/16" line dropping to 1/8" would be great!

Joe - I'll let others chime in, but my '65 has a lot of oil running to
the head. It used to leak a substantial amount from under the rocker
cover, especially towards the back of the head. I followed
recommendations and popped off the valve cover, cleaned it, ran a bead
of RTV sealant around it and bedded in a new valve cover gasket.

It still leaks a bit. Not nearly as much as it used to - but that
helped quite a bit. My '65 has a fitting, then has a line running to a
fitting in the head. It's a straight shot, and a LOT of oil
(especially noticable when popping off the valve cover and adjusting
the valves).
