symptom...........water in the oil--------oil in the water----------water in the exhaust
waterpump was obviously bad, had silicone and a screw shoved up the drain hole for when the seal fails (no doubt in an attempt to make it not leak on the ground)
replaced internals and cleaned up the pump.........
leakage test cooling system and still about 1 psi loss over 2 hours
Cylinder leakage test on the cylinders shows less than 5% on any of them but #3 cylinder has air blowing out the KLEEN dowel hole under the valve cover.... (was doing valve adjustment anyways)
-------obviously has compressed air pushing into that bypass hole in the exhaust port or through a crack in the head, but how/why
Engine out, head off and #3 cylinder piston is washed clean from all that water, headers drain out about a pint of coolant, combustion chamber of #3 also washed relatively clean
Check head for flatness and head gasket for evidence of water getting by.....both appear good and head is definitely flat even with the old gasket material still stuck to much of it.........nowhere would a .001" feeler get in anywhere or even try and the .0005" feeler only fit in the non gasket covered areas (I guess we can surmise the gasket material is about .0005" thick)
pull valves, put compressed air directly in that KLEEN passageway in #3 and hold a finger over where the dowel fits...........lots of pressure but some air is going into the cooling ports of the head, I can see it moving some of the residue water around
Yet I cannot see any crack or anything at this point.............
Time for more cleaning, but I surmise the head is toast and likely cracked between the water jacket and that KLEEN passage, but then why water in the cylinder?-backfeeding past the valve when open
And this also does not explain where oil in the water is coming from
Unless..........the waterpump was the first issue and them plugging that only made things worse.............and the head is a separate issue........
Good thing it is winter for a couple more months.............
But it seems at this point it is likely cheaper and easier to get a cylinder head and then disassemble the entire engine and .........new rings, new bearings and check everything else out closely...........who knows how long it ran with water contamination or what else is wrong with this 22,000 mile bike as a result of this or other neglect and stupidity
