Where Do I Go To Get An Oil Pump?

[SECURITY]

ive rung a few places so far, justjap, uas, and nissan. nissan want 500+ for a standard rb25det oil pump and justjap and uas dont stock the standard pumps.

if worse comes to worse ill be getting an n1 pump from justjap for 499 but does anyone know anywhere else that would have standard rb25det oil pumps?

[Tosh]

you really don't want a 2nd hand oil pump mate. You've gone to the trouble of re-building the engine so put a new one in.

[SECURITY]

im not looking for a 2nd hand one, im looking for somewhere that sells them cheaper or can i only get it genuine?

[N1GTR]

Yeah go new, heres a link to the club discount guy

Powerplay did a oem airbox for a good price for me ages ago, give them a try maybe?

[SECURITY]

thanks mate, but none of those guys work there anymore.

[N1GTR]

Troy?

I got some stuff off him last month

Oh well, just say your buying on the Skylines Australia account, and its COD only

[SECURITY]

ok well it might not be my oil pump after all.. could be clearances.

now ive got to rip the sump off again

[N1GTR]

That sucks, still, remember the a/c/ details for anything in the future

[SECURITY]

thanks alot for that mate.

[N1GTR]

No worries, what exactly is wrong with it?

Wont turn over?

Steve: Troy at Nissan has left, and the new guys are useless

SECURITY: I really think you need to be sure about what you are dealing with before you go buying a new oil pump unless you are certain that your current pump has a problem, especially since you are obviously doing this on a shoestring budget.

Lift the engine out, and strip and reassemble it properly - without using assembly lube on the bores!

[SECURITY]

we're going to pull the oil pump off and have a look at it, if it seems ok then we're going to look at the clearances of the rod bearings.

but we put in new standard bearings, and the old bearings were standard so the only thing left would be the oil pump.

whats happening is its running, except ive got what sounds like a lifter noise. just a clicking in the head, but that could be caused by the thinner oil and a dodgy oil pump.

oil pressure rises to 30+ psi when its at around 3000rpm, so its got me stumped!

i would reccomend a nice sharp, smokey burnout. should clear it right up. if that fails to work, dont look at me. just rebuild again.

That dreaded clicking sound again..............time for a rebuild but this time do it right , take the donk out and check everything so you dont have to do it again ...

[SECURITY]

it was done right, just because we didnt have a workshop doesnt mean it was done wrong. and to the best of my knowledge the oil pump was fine so we didnt think of changing it.

it isnt a big problem. its either the big ends or oil pump. ill be changing both while the sump is off anyway. bearings cost me $60 so it isnt a big deal to change them to be on the safe side. im buying an n1 oil pump this thursday so it'll all be fixed over the weekend.

i think what most people are trying to say is that doing a rebuild while the block is still in the car is rare and you might not diagnose the cause of your problem properly.

Mate you don't understand its got nothing to do with having a workshop. Take the engine out of the car, take the crank out and have it checked by someone that knows and has the tools to do it .You say you checked the bearing clearances , how can you do it on the car ? By using new bearings again its not going to make any difference if they are the same size as before .

You must have done something wrong otherwise she would be fine. If i was you i would check the piston to bore clearance too , it has nothing to do with oil pressure but it may have something to do with the clicking sound ( piston slap if the clearance is to big ) . You should also service the cil head while you are at it, saves you having to pull it off in the very near future .

[SECURITY]

im just going to leave it to my brother in law. hes confident he knows what the problem is, its too much of a damn headache for me.

thanks wrxhoon, hope you dont mind if i pm you another time if ive got any problems mate. cheers.

security I understand you are trying to do this cheap but I guess the point is you've done a commodore style rebuild on a skyline

I'm sure you want car that you can take back to the strip and trhash when you are finished, for god sake don't cut corners and end up with a problem a third time.

Take the motor out

Get the bottom end cleaned and tested and honed properly

Deck the block

Then have the bearing, piston and ring clearances checked.

Buy a new oil pump.

Get the crank measured for straightness.

Get it all balanced.

Get new rod bolts.

Get the right size bearings.

Check the ring end gaps to make sure they are right.

Make sure you have the right grade pistons for your current piston clearances.

Clean the bottom end out properly instead of leaving the shavings from the honing floating around in the block.

Shave the head

Get the head pressure tested

Yes I would know I've done it cheap and wrong myself.

Or failing that do what I did and install a second hand motor. The fact is you did hge damage with that melted piston but never cleaned the block out....

Good luck with it all

I'm with Duncan & WRXHOON. Take it out and do it properly or you're pissing money into the wind. It's just going to break the way you've built it now there's been too many corners cut. You CANNOT build an engine properly, especially a high performance once, without taking it out of the car.

If you're not going to listen to the answers don't bother asking the questions, we're only going to tell you "I told you so" afterwards.

Good luck getting it sorted anyhow but for your own sake please take the engine out and build it properly.
