Target the rocker hold-down area...mimic the factory breather location.

This is pretty much the way I do it... over top of
the wide rocker shaft hold down towards the front of
the cover... that area gets the least amount of oil

Ari440, How much oil do you get in the puke tank after a run with the fitting on top?

I have a baffle under the breather hole in the same location as Ari on my Indy valve covers, so I will try that first before drilling new holes...

Thanks,




I get less then 1/4 of oil in the tank

my regulater is setup at 12 pounds of vacume

I have no baffle in the valve cover but use the a fitting thats drilled holes all around it

also im useing regluar molley rings 1/16

Thanks WESW,

I notice you have it closer to the intake on the front of the Valve Cover, than the exhaust. Any logic to that?

I have the Star fitting that is open on one side only. I am assuming it should face down for the opening??

Thanks,

Arnie

I am running individual shaft mount Jesel Pro rockers with pushrod oiling, so maybe thats why the top of the vc is not working for me?

If the Star pump does not pull vacuum with oil in it, then why does mine continue to pull oil into the tank every run?

Please educate me as this is driving me nuts cleaning oil off the motor every pass...

Thanks,

Arnie

are you using the Star tank?


and Star fitting ?



if not the pump is not being used properly. STAR does not even stand behind the pump when used witout the cannister. That pump is to be run dry and not see any oil at all.
the baffle placement is your problem

*Oil in the Pump:
The Pump is a “OIL-LESS” design, which requires NO LUBRICATION for operation. Oil in the Pump will not damage the Pump,
however it will reduce its performance. The dryer you can keep this Pump, the better it will work! The use of a baffle is mandatory!
This may require several modifications to the location and design of the baffle you draw vacuum from. How will you know if oil is in
the pump? If you use clear hose and the hose shows signs of oil in it, the oil will be in the Pump also. If you remove the belt from the
Pump and spin it by hand and you do not hear the vanes tapping (as they are flung from the rotor) you have oil in the Pump. To clean
the oil from the Pump, remove the hose from the intake side of the Pump and spray nonflammable (environmentally safe) solvent into
the intake tube with the engine running. Mind the Pump exhaust when doing this! You should make this part of your usual race car
maintenance.
Excessive oil in the pump is usually a clear indication of a failed seal or gasket. STAR Machine has a tank available that combines an
oil separator/filter and an exhaust tank in one unit, Part #02.09.000. STAR Machine will warranty this Pump for one year only when
used in conjunction with this tank.
