Anyone ever have problems with the cam gear and
distributor gear getting chewed up with these
high pressure pumps ?

Doug,

That is the exact set-up I currently have. Something went thru the pump because the rotors were chewed up and the pump housing is grooved pretty bad. Still carried decent oil pressure. Looking for the best fix to this problem. Sounds like I can get away with just replacing the pump. The Indy cover does not have much damage/wear.....seems to mostly be contained to the housing and rotors.

The covers are easy to mill. We only trim where it bolts to the pump and stop short of where the inlet screws in as it is pretty thin already.

The original Milodon pumps were hard anodized. I suspect the newer billet pumps are just color anodized. Milling brings you to the bare aluminum and just the weight of the rotors is likely enough to cause wear against the unanodized surface.

I bought the Milidon pump and use the stock cover with a Jomar 100% no bypass filter. The rotors are more pointed than the rounded clover shape of the stock pumps resulting in using less power to spin them.

Earlier this year, I lost some rocker arm bearings on my exhaust rockers as a result of my valve spring pressures slowly going away and valve float harmonics beating up the related parts.

Once I get the motor apart, I'll report on how the pump and gears held up to any contamination. I'm hoping the Jomar filter kept it all out of the pressure side of the motor.

I'm pretty sure the oil flows through the pressure side before it goes into the filter !!!

I think when he says pressure side he is talking after the filter, but you are correct in thinking that the oil is pressurized before the filter, unfiltered oil travels thru the oil pump first and then to the filter.


running up my post count some more .

Ya, I re-read his post and see what he means. Not concerned so much about the pump as he is about the motor.

I know plenty of shrapnel went thru mine. 8 broken valve springs (6 inner, 2 outer). I ran it another 1 1/2 years. Though the pump was chewed up nothing else was hurt. Even held 65 psi@7000 with a broken relief spring.

I put a Milodon dual line system on a 446 for a S/G car in 1990.
The system I used had the milodon pump cover and sandwich plate with a Melling HV pump in between. Back then, there was no green gasket for the filter adapter...... It had recsssed grooves and o-rings.
That system got transferred to several subsequent motors and is still in use today on an Indy headed 542.

When dinoing my motor at wescotts we put one of his pumps on my motor and it was worth 4 hp. His gears in that pump where copies of a Chevy pump. I thought it was some what of a copy of a jeff Johnson pump witch uses Chevy gears. Charlie tried one of his and decided to do his own. It was a great pump and cheaper than the Johnson

They are a bear to cut open for inspection due to the heavy case.

They call it a pre filter,but it's a screen and the canister unscrews for inspection. I have one on both pick up lines.
Jimi Vignogna instructed me to install a pair after a lifter failure and the entire oiling system got contaminated.
