Recommend a Method to Prime Maxima Oil Pump

[1993_VG30E_GXE]

I can't use the drill method to turn the pump over...this pump doesn't have that function. Does anyone have any suggestions?

Someone told me to maybe hook something up to the oil pressure switch hole or something and pump it from there. What is he talking about?

I also have access to a 2nd Drain Plug on the block itself (identical to the pan plug) but I don't know what it feeds, that isn't normally accessible when the engine is installed in the car. Can it be primed while on the stand through this hole also?

Hmmm.. (what can I pull out of my behind?)

I think I would have packed the rotor with petroleum jelly at the time of assembly ..but not knowing any preferred trick way ..

If you didn't have an ADBV on your filter, I'd say just tap a hose into the pressure port and add a funnel. It would take a while, but it would get there. I tried to find some 3/4-16 thread filters without ADBV. The ones that didn't mention them in Donaldson did have them in Wix ..

If you had the Spectre 5971 oil change kit, you could remove the filter ..hook up the remote block adapter (it comes with hose barbs) and do the same thing. You could probably use the included pump, but I doubt that you can move the volume. Amazon has them.

I guess if you had a Permacool block adapter it would work too. It's just the Spectre has all the hardware included.

I hope someone comes up with a better solution. I might encounter this some time in the future.

Thanks - and hopefully a makeshift solution, as I don't want to buy anything special for this since i'll probably never use it again.

The pump is a Paraut #V4-034

It comes in a bag and is coated in some stinky yellow 'offshore' type grease, kind of like what comes on the machinist tools when you buy them. Does this mean the new pump is pre-primed itself so I don't have to open it up and do anything to it?

This is on a side note by the way to priming the engine.

Oh - I forgot to mention my machnist friend said not to even bother priming the engine - he said that's what the Lubriplate 105 lube is for, and that it only takes seconds for it to prime once it's in motion. With the Lubriplate 105 he says there will be no damage so ignore the priming. Any truth to this?

He claims in the Nissan factory there's likely no way they even prime the new engines on the assembly line.

I wouldn't worry about priming but one way to do it effectively is to back the pump full of grease.

I don't get it, is the risk that air is in the pump and it actually won't suck oil when it starts up? Another guy told me to open up the pump and just soak it in heavy oil.

Here's something too guys check this out. It looks pretty cheap - but I don't know if it could build enough pressure to push the oil where it's supposed to go:

The idea is with no oil in the pump it doesn't seal well enough to create enough "suction" to pick the oil up and start pumping.

That pump you linked to doesn't generate much pressure.

I put an extra 1/2 qt in rebuilt engines, for a bunch of reasons.
For pumps, this help a bit with a bit more head pressure.
At least soak the pump gears and housing with engine oil.
A little Vaseline jammed around the gears is an old trick.
You can crank the engine with the starter [possibly with the spark plugs out] to prime the pump. Yank the fuel injection fuse and coil power.
I hope you are using a lighter oil for the first fill.
5-20 or 5-30. This will help initial flow.
