Thread: Oil Pump Differences?

    Oil Pump Differences?

    Hi everyone,

    Got 2 quick questions:

    1) Is there any difference between a Seal Power Oil Pump and a Melling Pump? I guess what I wanna know is if the Seal Power one is good or crap?

    2) Is there a diff between a turbo and nonturbo Oil Pump? Also is it worth to put in the high pressure spring in the Oil Pump? It's for a street car.

    Thanks, Alex.

    No difference, get whichever one is cheaper.

    Remove the tin cover on the pickup so there is no restriction.

    Yes, use the spring, gives a little more pressure when you need it most. DON'T buy the High Volume pump.

    I have been told (DC engineer) that a high volume pump is ok. High pressure is NOT. You don't want to be blowing oil through the seals in your turbo.

    You get the spring from Mopar, P3690944

    HV pumps suck HP and honestly, our engines don't need it, unless your autocrossing, high pressure, hmmmmmm, I would say a bit more than stock is fine, using the spring but no need to go crazy. Stock is the best way to go anyhow.

    The spring raises the pressure a few psi, I think around 10-15psi.

    A autocrosser said he uses the HV pump and baffled oil pan to keep his engine safe, he found out he needed it. Can't remember his name.

    You drill out the little cap then install a screw and pry it out. The spring will pop out and then the relief valve will fall out, or it should. If its an older pump, clean it up, lube the relief valve and make sure it moves freely, if not, you will have too much or no oil pressure. The valve goes in with the hollow end facing up. Install the spring then the cap, the hollow part faces up. Tap it down and install the cotter pin. BAM, your done.


    Your welcome Andreas.

    NO, if theres a hole in the cap, you need to seal it, otherwise your going to have oil pressure issues.

    Get a new cap but your going to have to match one up, you can't buy it seperately. If you buy that spring kit, it comes with a new one. Otherwise I would weld the hole up.

    Re: Oil Pump Differences?

    cool, I just ordered my spring today. Total cost of $4.24 and will be here tomorrow.

    I also was told by the service guy when I asked about oil pickup lines that it would take a week to bring one in and that there are only 30 left in chrysler supply. INteresting fact there and yes I know I can get one on TU.
