Failed water pump seal opinions please
Hope that you guys will help me with a little problem I am pondering over.
Recently purchased an 06 990 adventure With 33k Kilometres. Service history was a bit patchy. Lots of receipts and warranty jobs done at a KTM dealer with a dodgy rep. It had its last major at 31k but as I plan to take it to Africa next week (no pressure) and even though the bike was running well, I thought I'd do some PM and do the usual stuff that may give problems. stripped her and did the valves, all were within spec. Then replaced the water pump shaft, seal, both bearings and impeller. When I took off the inner clutch cover it was apparent that there was coolant in the oil. To me it seems likely that the pump seal had weaped through to the oil, or at least this seems more likely than a head gasket. I haven't noticed any coolant loss, but have only done 600 Km's on the bike. So I drained the oil, but I did this when the engine was cold, as I really hadn't planned to change 2000 km old oil. The oil filter has slight waves in it, so I don't think this has been leaking for long, but there are large white globs from the coolant in the drained oil. So here is my question (if you read this far, thanks for your perseverance!). As I drained the oil cold and there is clearly going to be a fair amount of contaminated oil in the engine, should I;
Fill with cheap oil of the appropriate grade, run the bike to temp without an oil filter, drain the oil again and full with Motorex?
Go with the Motorex straight off and run it for the next 7500 km's?
What do you think? Are there any alternatives to either of the above? Any guidance much appreciated.
