FFS I hope mine will be ok!
I got mine off Richie B9KOS as his got recalled by Cosworth (so he had to buy an additional from GGR) so I bought the new one Cosworth sent out....
We were talking to someone at Cosworth at the Ring last year, we slagged him off for the lack of oil pumps and questioned their design.
He said they'd been sorted.......... Obviously not unless this was part of the old batch (doubt it though as this was last year).
