I think I am giving it too much oil...thanks heaps for the heads up.

the sprintex kit has a weep nozzle that blocks up so I opened it up a bit...


Which oil are you using?


might try your way.

should i modify mine ???

With all due respect to Bongo ...I have had a rethink on the advice about too much oil.........

It might be the case on the Ford where the oil is locked in...but on our kit the oil is sucked out by the rocker cover vacuum...so it cant really be overfilled because it just flows from the bottom of the nose assembly.

If I make it way too big i would lose overall oil pressure so have been careful about it.

I did actually speak to Mark at sprintex, he approved the idea as long as it wasn't TOOOOO big a difference.

Yes that is probably the best way of doing things for your setup. Yours is factory,, whereas I built mine myself from scratch & bolted the S5 onto the old girl.

I was thinking of kitting mine out with the vacuum oil feed, it seems that it would be a more efficient way of doing it.
By the way, did Mark Ambrosius (from Sprintex) have any ideas as to why the bearing may have failed in the 380?

Ours uses the engine oil which is rated at 10w/40...with recommended intervals of 10k/klm.

Yeah lack of oil is what killed my bearings.

I have now had 6 failures between three cars.


Admittedly 3 of them were low boost issues with series 3 blowers that were replaced free of charge with series 5 units.

The reason I enlarged the oil feed was to abate the bearing failures...I think I am on top of it now.
