It's a bit like the hare and the tortoise. Here comes Foxy with his little Tortoise Engine.... chug chug chug... and on into the sunset... You’re wired up very differently from mist people. Is that froggy or foggy?

Got to the boat this afternoon, loaded up and set off from Nantwich heading south to Audlem, oil light was flickering, unusual I thought as I had checked oil last time we cruised, pulled over and let engine cool for 10i minutes, dipped tank and shit myself, level a good two inch above max line and colour milky grey.. checked water and no sign of losing any so god knows where the water has come from. Have now pulled 6L of this shit out the dipstick Hole and put some oil back in, ran engine and no sign of anything bad, oil still looks grey but not rising on the dipstick.. will see what happens in the morning.. Safe to say head gasket or maybe water pump? More information needed, beginning with make and model of engine, . . it could be head gasket, it won't be the water pump, unless it's a rare and unusual type - such as a Petter Cub - with tandem oil and water pumps on a single shaft, or a water pump driven off a crankcase or timing case drive, it could be a faulty engine or gearbox oil cooler, . . if it's fitted with one or the other, or both. Was the engine noticeably hotter than normal when the oil light began to flicker, or did you assume it was over hot just because the oil pressure warning light was coming on ? What sort cooling system does it have - closed circuit keel/tank cooled, closed circuit heat exchanger cooled with overboard discharge from raw water circuit, or raw water overboard discharge cooled ?

Ah yes.... the Mist People. Allies of the Cybermen! Nantwich Marina wanted £90/week for mooring a 40' narrowboat... which is why we gave them a miss. Still, they have a well-stocked chandlery, and the cratch cover people there sold us some of those poppit thingies. Anyway, if someone works on your engine, make sure you are there watching, so you know what it was all about. And take photos to post here.

Ricco’s post is interesting as the header tank shows no sign of water level dropping, could diesel be getting in there maybe.. I didn’t notice the engine being any hotter due to not having a gauge.

Does sump oil turn milky-grey because it is contaminated with diesel? I would tend to think not. Also, you only need a bit of water in oil to make 'suds'.

I can't identify it via anything on the internet from that Kubota designation, . . is it the model that Nanni are now marketing as the N3.21 or the N3.30? A photo or two of your engine showing all the cooling system plumbing would be useful. There won't be any diesel (fuel) getting into the cooling system, but depending on whether or not your engine is fitted with an oil cooler, it is possible that coolant might be swapping places with the engine oil if the cooler has developed an internal leak, . . which is something oil coolers are sometimes prone to after being put back into use following long periods of standing with few or no running hours ! Did the engine get hot enough to blow rusty coloured water out of the header tank cap ? Can you see any small bubbles rising in the header tank when the engine's running, and is there any detectable trace of an exhaust fumes sort of smell coming out of the header tank filler whilst you're looking for bubbles ? Are there any droplets or signs of oil floating on the surface of the coolant in the header tank ?

It seems odd that childminders would marinise engines.

I've seen head gasket sealer in car supermarkets, pour it in the water it seals the blown gasket. Probably only for a while. It may be a temporary measure to get you by.

An interesting day, took the bike into Nantwich to get some more oil and a spanner coz none of mine were big enough to drain the oil, drained the oil and filled back up with fresh stuff, then cruised for the afternoon, stopping a lot and checking fluids, no sign of any water in the oil now and water where it should be in the header tank.
I’m confused now.

Yeah maybe, I did find a leaking water hose from skin tank to engine leaking but this was sat on top of the gearbox, so god knows how that would work it’s way into the engine

I’m confused now. You could make a start on unconfusing yourself by referring back to the two posts I made further back on this page, . . in particular to the second para. in this morning's post. Here it is again with the more salient points highlighted in bold : There won't be any diesel (fuel) getting into the cooling system, but depending on whether or not your engine is fitted with an oil cooler, it is possible that coolant might be swapping places with the engine oil if the cooler has developed an internal leak, . . which is something oil coolers are sometimes prone to after being put back into use following long periods of standing with few or no running hours! Further opportunities for yet more understanding can be had by responding to the questions I asked you in the third para. of the same post. Here they are again - a "no" to all of them would pretty well eliminate the head gasket as the source of the water contamination in the engine lube oil : Did the engine get hot enough to blow rusty coloured water out of the header tank cap ? Can you see any small bubbles rising in the header tank when the engine's running, and is there any detectable trace of an exhaust fumes sort of smell coming out of the header tank filler whilst you're looking for bubbles ? Are there any droplets or signs of oil floating on the surface of the coolant in the header tank ?

That stuff is worse than useless and all it will ever do is to block the smaller water passages, kill the engine and make it permanently unrepairable. You cannot repair damaged metal by tipping any type of product into the oil or water system.

Gearbox oil cooler is quite possible. However in the original post @froggy did say that there was no loss of water from the header tank.
I'm not quite sure how this tallies up with a leaking hose.
I had a strange problem with a cooling system years ago which turned out to be related to a problematic calorifier. But that was not milky oil it was an overflowing engine coolant header tank.

Yeah maybe, I did find a leaking water hose from skin tank to engine leaking but this was sat on top of the gearbox, so god knows how that would work it’s way into the engine I tried to work out a similar mystery a while back. The 2 stroke oil from a separate tank on my bike was somehow making its way into the gearbox. I never did get to the bottom of it. I just sucked a bit out from time to time and carried on until I sold it.
