I have unfortunately holed my oil cooler, sods law on my first bimble of the season Replacement has arrived and I'm going to do the swap myself. Anyone know of any potential gotcha's? My assumption is that all the oil sits in the sump, so should only be whatever oil is sitting in the cooler? Remove the relevant plastics, disconnect the hoses, fit replacement, refit plastics and top up the oil if needed. have an Evotech guard to fit at the same time to stop reoccurance
