ProCharger Oil Return Ideas?
 

I was wondering if anyone has come across an easy way to plumb the oil return to the pan on a PC set up.
The instructions say punch a hole and tap with heavy grease.
Got to be an easier way.
Any ideas?
:confused:
Thanks in Advance,
Dave

Does your block have a mechanical fuel pump boss that you're not using? Seems to me I remember using that trick years ago for a turbo oil drain.

When I installed my ProCharger, I was able to use a plug that was on the side of the oil pan. Look for it on the port side of the engine.

...Got the fever has got it. Most pans I have seen are tapped & have a plug installed. Perfect!!:D For the source oil, tap into an unused port on the filter boss.:cool:

You could send the PC in to make it self contained. Seems to be very dependable. Punching the hole is not as bad as it sounds.

Mike at ProCharger said that oil return must be run to a spot "underwater" in oil (the pan). Any return line that dumped into the valve covers, fuel pump boss, or other spot "open to the air" CAN lose the aid of gravity to self-siphon the oil and allow the oil line to drain from the bearings and possibly let the oil run back down the feed line, leaving a lot of air in the lube line on the pressure side. They have witnessed some bearing failures because of this and even though the chances of trouble from it is slim, it is still real and they cannot give their blessing to any return line routing that does not terminate below oil level in the sump.

Terminating in oil, there is no way for an air bubble to reach the bearings.

Thanks Guys...
 

Hey Tom,
it's a Gen 6 block which doesn't have that provision.
Fever,
I belive that also is a pre-97 set up and I don't have a stock pan anyway.
Blown Formula,
I'll have to take a look at that. Are you talking about the plugged remote filter holes that would be used for a cooler if we weren't using the remote filter adapter? I was also thinking about using the oil pressure sending unit with a "T" or the adapter that goes on to the remote filter housing.
mcollinstn,
that's very interesting. My 14 qt. pan has an oil drain hole sticking out the back right near the borttom. Before installing the motor we inserted a barb fitting into that hole and attached a 3/8 ID hose to it for draining purposes. Couldn't we just drain to that. I thought that the oil would have to drain freely just above the oil level. If it is to be terminated below the oil level then wouldn't this work or is it too deep?
Thanks,
Dave

Oil Source - remove a plug in the remote filter adapter as a source, not the oil pressure sensor with a "T". Much cleaner install. :cool:

I wish I could now find my procharger book. I will look when I get home to see if I have it there.

I know this is not a turbocharger but with turbochargers you want the returning oil to return above the Oil level in the pan & hose to have a continual downward slope from the turbocharger so gravity will take the oil to the pan. If I remember correctly (Tomcat, corbra M will chime in if I am wrong) the oil comming from the turbocharger is all whipped up from going thru the bearings. If this oil returns below the oil level it will not flow into the pan but will back up into the turbocharger & be forced past the seals.

I do not know why a procharager would be any different that a turbo in this aspect.

The statment that was from Mike @ Procharger does not make any sense to me. Maybe I am missing something.

What you say is true for turbochargers. I don't know why it would be different for any other centrifugal supercharger, but turbos generally spin faster, so maybe the whipped oil is only a problem for them?
