Hi, all !! Some of you have seen and replied to my earlier thread on oil filter housing and oil pan gasket replacement on my 98 XJ and now I have a couple more questions.

In the past whenever I replaced an oil pump it has always been on a newly rebuilt motor and I ALWAYS primed the pump til oil squirted out the rocker arms but this time the motor is not new. Since the oil pan is off, I have decided to replace the factory pump with a Melling High Volume unit. The pump comes with instructions to dynamically prime it like on a new motor. Is this really necessary or can I just load it with some oil before bolting it in place or must I pull the distributor and spin it up with a drill or speed wrench? Is there another method? ..... a flatratin' shortcut or an old Indian trick for making sure not to starve these motors before the pump picks up? I don't want to fry this motor Any input would be interesting to me. Thx.

My suggestion would be to call tech support at Melling and ask them but my theory is better safe than sorry , I would follow thier directions then if thier is a problem they would be more likely to help you out on it.

 

You can bet that I will err on the side of caution if no one comes up with something else that makes sense to me, for sure. Thx for the input.

 

Vista I think it could go either way. The purpose of the dynamic priming of a new pump is to get oil into areas that are dry from a rebuild. So since you don't have that suituation it may not be required.

 

That's along the lines that I've been thinkin' too, Blue. We'll see what other input gets posted up here in the next day or so. Thx.

 

That's what I do. Give advice.

 

I would make sure its full of oil. button up the pan, Disconnect Ingition and spin it over with the starter a bit.

 

Thats the way i'd do it as well, versus starting it dry.

 

Yup ... likin' what I'm hearin'. Thx all.
