No problem, we are talking a good 40min or some idle and some blips. Then I've done an oil change with new filter.So with it on the drive rev it and oil filter comes flying oil everywhere obviously
Luckily being build stage this is on the drive and engine off within 3 seconds.
I actually seem to of only lost about a litre of oil by some miracle! my lovely new oil 
Anyway it appears the oil filter hasn't come off,
(good to know I can fit one!) but infact the oil filter centre piece which screws into the bracket has come out with the oil cooler! Very weird I thought and test screwing it back in and it started to go but never ended, so I stuck my finger in and the threaded part of the bracket has broken. Now this has never been touched on the engine, so obviously me doing a filter change has disturbed something that had become weak.How could this occur I can only think its been over torqued in the past and just became weak and im lucky the sod to push it over the edge.
Or the threads have been stripped slightly with the over torque and it was a ticking time bomb!Next question;
Metal shards will have obviously gone down with the oil so the oil will be changed and I have magnetic plug anyway, but what is the best way to flush this part of the system?
last question, is the oil coolers and brackets the same on Rev2's as rev3+?
Shame.
..this was the last mechanical job as i waited on my license plate , should of seen my face!
