The first bad news is that I replaced my
romote oil filter mount and installed a new filter. As I have mentioned
here I have had it leaking at the rubber filter seal. The old one looked
ok, but since replacing the filters no less than three times and knowing
that the eye cannot see all inperfections, I replaced the mount AND filter
(K&N 2004 filter). But, NO JOY. It is still leaking where the filter
mounts. It IS seeping from the filter seal and NOT the two hose
connections...no doubt on this. I know the rotary's oil pressure is
higher than other engines but I would not think it would be so much that it is
overwhelming this standard mount and seal. This is just a standard screw
on remote oil mount made out of AL...Made in the USA. Looks like many
others I have seen. Y'all have any ideas.
Chris,
When I was much younger, and much more foolish, I
had a 66 mustang fastback with all the go fast additions. The engine was
lowered in the frame and moved back a ways to help the weight distribution.
Doing so required a remote mount oil filter. I had a terrible time with leaks.
There was no internet at the time, and info was hard to come by, especially in
BFA.....(a popular derogatory phrase involving the substitution of Arkansas for
Egypt). Eventually I figured out that the problem was the fittings not the oil
filter. I had NAS type fittings and braided lines from the block to the filter
mount. The filter mount had female NPT threads. Being that I was a perpetually
poor kid, I used some brass hardware store fittings for the pipe thread to NAS
joints. Two problems: Pipe threads are terrible and I hate Teflon tape because
it is a pain in the ass, leaks, and the shreds can get into delicate stuff and
clog/break things. The second problem was that although the NAS fittings will
thread onto the hardware store fittings, the tapers are incompatible and will
not seal adequately. The solution was to get proper NAS fittings and to use a
good high quality PTFE based pipe dope. Pipe dope is messy, but it is one of the
best things I ever discovered. It always seals the first time, and will simply
dissolve into hydraulic fluid or oil and will not harm or clog anything.
I had thought the casting was bad or something, but
the seep was only happening when the engine was warm and the oil was thin. It
was small and drained down into the filter/seal area and by the time I looked at
it the evidence of the seep was gone..... Check carefully when the engine/oil is
warm and have somebody rev the engine while you look very carefully at the area
around the fittings with a bright light.
I HATE TEFLON TAPE!!!!
I HATE PIPE THREADS!!!
I never got a ticket in that car (which is a minor
miracle), but your brothers in blue used to pull me over constantly just to look
at the car.
Good luck.
Monty
