Evening all.
Bit of a strange one, but when checking the car over before a recent trackday I noticed a small oil leak and upon investigating further I found my oil cooler looking like this.
It's a 16row mocal jobbie with a thermostatic sandwich plate, fitted to a xu10j4rs.
Whilst I have done a few trackdays, I think the damage was caused during day-to-day running. Has anyone seen this or could perhaps offer an explanation as to what may have happened?
I am happy to replace the cooler but I am nervous of doing so if the same thing is going to happen again.
Cheers
