Raceproved Preoiler

[twinreal]

I wonder if there are many of you out there having the raceproved preoiler installed.
Does anyone ever unplugged the hose from the cam cover and then started ?
I have, and --> nothing !! No oil is getting pumped at all !
Then took off the hose that goes to the filter and no oil, too. So i think the pump is dead.
It is an Jabsco/Flojet Triplex diaphragma pump type. The max. working temperature of these pumps is 60 degrees C ! So no wonder the pump went...
Maybe take a look at yours.

I know the preoiler is an often discussed expensive piece of thing. Personally i wouldn't have put it in, but the former owner did. This should be just a quick info for those who believe in the function of the preoiler :-)

Clive, isn't this too much oil pressure for the spray bar inside the cover ?
Before buying a new pump i will throw out all except the cover....

Clive, i will give that a try. Just to my understanding:
Removing the pump and the feed from oiltank to pump is clear so far, but what about the 4 way adapter ? At the moment the 4 feeds are going to:
1. Raceproved pump
2. Engine block
3. Oilcooler
4. Feed to the cam cover
So the cam cover is already connected to the oilcooler, isn't it ?

Thanks,
Thomas

Originally the oilway with preoiler is from the bottom of oiltank to the preoiler pump - from the pump to the 4-way adapter. From there one feed goes into the block, one goes to the oil cooler and one goes to the oil filter housing. Finally from there a feed to the cam cover.

Yes, love the cam cover, too. The spark plug cover is much better then original.
I think i will leave all as it is and just put back together the bulkhead connector in the drivers footwell so that the preoiler ECU is disabled.
