Thanks for the replies guys. (Apart from Brian's)

So, the upshot of this is that I'm now confused even more.

I'm under the impression that the max pressure the cooler needs to be able to cope with is around 80psi, as its not particularly pressurised but merely a passage way back to a pressurised crank case ?

Maybe I should have paid attention more at school !

Worst case scenario is you have a blockage on the return resulting in the cooler getting exposed to the maximum pressure at high revs.
Must be a rare occurance as I can't recall a specific case of this happening

Several suitable Ducati oil coolers on Ebay for a round £70, so what is the repair cost and what would the cheaper alternative cost

I recall someone using a 749 oil cooler, think it was Rattler
But it now £50

or bid from £30

New 7-Row Mocal Oil coolers cost about £60, but then you need to sort out the hoses with the correct fittings

The pressure going in to the cooler will be much less than 80psi due to an open return back to the crankcase, and crankcase is not under pressure, if it was it would blow a seal, hence the breather at the rear.hope this helps

Just sold one for £30 on ebay

That does it for me, thank you.

That is most certainly the sort of "lay mans terms" I understand !

Also, cheers to Kev (again) for the input, I'll let you know on the costs, etc once I've spoken to him.

Cheers fella's.
