how do i prime an oil pump

[hrtmad]

i own a 5 litre manual vt clubsport

I replacing the oil pump, how do you prime the pump,

ive heard that you put vasoline in it, is this correct, if so do you pack the whole pump full of vasoline, or just lube the gears and gear shaft then fill it with oil and fit the pump (filter included) to the car

[hail storm]

Yeah mate pack the pump gears full of Vaso and fill the filter with oil.Remove the spark plugs so the engine spins fast and watch the O/Pressure gauge

[hrtmad]

how long do i let the engine turn over intill i get normal oil pressure

how long do i let the engine turn over intill i get normal oil pressure

'Till the oil pressure light goes out..

[fitz_vt]

pretty much once you have vaso'd it once u whack it in put ur oil in, then run your vehicle for 5 minutes at least bring it to the normal operating temperature (75-100 degrees) once that has happened your oil pressure light should turn off if not even before then. * should turn off*
if your light does not turn off ..... TURN OFF YOUR ENGINE, let it cool down and as posted below start again.

then run your vehicle for 5 minutes at least bring it to the normal operating temperature (75-100 degrees) once that has happened your oil pressure light should turn off. * should turn off*
if not run your engine until the light goes off if the light doesnt turn off you have done something wrong. turn off your engine let it cool down and inspect the pump.

I personally wouldn't run my engine with the oil pressure light on for 5 minutes lol that is asking for trouble.

get a proper oil pressure gauge and use that. the principle is, the gear pump that pushes the oil around your engine isn't real good at self-priming (not a good air seal) so packing it full of vas or grease maintains this seal, so when the pump is rotated it can create negative pressure on the intake and the oil makes its way up the pickup so the pump can operate as planned.

It should quieten down after 1 minute or so max. If it doesn't, time to start again

yeah essentially what needs to happen is for the oil pump to engage, and start pumping oil around the engine.... to do this properly the engine needs to be at normal opearting temperatures........

[hrtmad]

So what is better to pack the pump with grease or vaso, i was actually gonna use both hail storm and fitz_vt's idea, turn the engine over with plugs out untill the oil pressure light goes out, then run car for 5 mins till normal oil pressure is achieved.

[andyman]

yeah just vaso,

lol....if the oil pump isn't turning, he's got big dramas. It's either turning or its not, there is no engaging or disengaging....

If you pull the plugs and turn the engine over, you should see good oil pressure in less than a minute as mentioned....It just sucks that you have to turn the engine over so long to get it. That's why the holden iron 8's suck balls, you can't prime them with a drill like chev, ford, chryslers....

[hrtmad]

once its primed and engine is running and everything is sweet, do i need to change the oil again to get rid of the vaso, or will it be fine to run on untill the next oil change

[VT-565]

I'd do a change to be on the safe side, at least to get rid of any foreign materials that might have found their way in.

I personally wouldn't be putting vaseline in to prime the pump. I have used just ordinary chassis or wheel bearing grease in the past to do this. Not much is needed, just enough to 'wet' the gears. When it pumps through it will just mix with the oil after it finds its way through the filter.

[andyman]

as stated it only needs a light smear to fill the tolerances in the pump to seal it up, the vaso will melt very quickly and wont affect the oil once it all mixes up,

well essentially it works in other words engage,activate, begin, energize, get started, ignite, initiate, introduce, log on, put in gear, put on, set in motion, start up, switch on..........

[hrtmad]

So just pack the pump gears full of vaso or both the gears and the round hole about 15 mm in diameter beside the pump gears, which i assume is hole that either sends or returns the oil from the engine

[howepower]

yea the whole cavity where the gears are and over the one way valve

[hrtmad]

Thanks Guys for all your help, have just installed the oil pump with no worrys

Okey Dokey, Captain Thesaurus.


In your original post it sounded like you were saying the engine needed to be at operating temp to engage and pump oil around the engine. Water under the bridge.

Good to see you got things happening HRTMAD.
