A couple of weeks ago I noticed some oil in top of rad. This was clean oil (no emulsion there or inside oil filler cap).There was no over pressurising and heater worked so I thought it may not be head gasket.This also coincided with a couple of gauges ceasing to work.
I thought it worth trying another oil cooler so I've just fitted a replacement (used item). I've flushed out rad. and I'm going to run it around locally with a couple of 'radflushes' in there and intend to repeat that a couple of times to try to clean the system.Am I wasting my time? Any suggestions? Thanks.

two possibles here:
1. someone put oil in the wrong 'ole.
2. headgasket gone.
I'd check oil level and top up as rqd, drain and refill coolant, go for a drive, check both oil level and rad (for oil). If both are ok it was cause 1 and all is now well. If not you need your big toolbox and a headgasket set.
