I think the small drive collar on your 32 crank is now fecked.

ie no drive to the pump, if there is still a pump!!

As this happened at 8000 Rpm, I think you need a new engine !!

:ufo: Have more mechanical sympathy for f**ks sake !

I keep thanking myself for buying the jun crank collar.

[awurth]

so does the engine still run? does it make funny sounds? I reckon you would have spun a bearing if that sort of problem happened at 8000rpm. A 33 i sold had fluctuating oil pressure after the guy bought it and it ended up being the oil pressure sender was failing so that dash was telling a different story from what was actually happening.

[Mr R32 M-Spec]

holy crap

sounds expensive. I'm getting an aftermarket pressure gauge as I think the sender is playing up intermittently on mine

could it be oil pick up is rat shit ?

I've seen two oil pumps in the last two weeks that have had the backing plate screws either undone or only finger tight. Neither have been previously rebuilt. But I reckon in your case something has been lunched.

Errr - I didnt get to see the oil pressure on mine prior but the word is the screws loosed and the bearings farked (big End). I found out afterwards the previous owner was getting eratic oil pressure readings and was advised the gage was d!cky. Now I'm looking at a full rebuild of my 32 GTR

im sick of hearing that its loose backing plate screws that cause the oil pump problems ITS NOT, i've heard it 8 times this week!!! Its the undersized crank drive on r32 that is the cause. The drive is not wide enough it causes vibrations which wear down the internal gears of the pump(fluctuating oil pressures) and AS A RESULT cause the screws to vibrate loose. Everyone with a r32 should invest in a $240 collett from jun to save them a rebuild!!!!

Well, you are right, but the backing plate screws coming out is not wrong

I couldn't support your view more in terms of a crank collar, or even R33 crank. Its not worth losing your engine over, I was lucky with mine still got the engine...

[Fitzpatrick Speed Works]

oh the screws and backing plate do come loose no arguement but its a result from vibration casued by the small crank drive, not that they just come loose for some reason and this causes the oil pressure problems!!!

[BoOsTeD_RB26]

Is it all R32s that have this small drive?

I could almost swear that the later model R32s (93, 94) had a bigger drive? Read it somewhere on here.

[R32-GTS]

yeh 93 onwards 32's have the bigger drive.

[Fitzpatrick Speed Works]

my gtr is december build 93 and it has the small crank!!!!!!!!!!!!!!! so i wouldnt take it as gospel that 93 onwards is sweet!!!

[R32-GTS]

Maybe second half of 93 into 94 then. Or something like that
