hshooter Posted December 9, 2011 Report Posted December 9, 2011 Apparently this bike has been sitting for a year, took it out to dumont for Halloween. Ran the bike on alky, and hasn't been purged to this day. Figured we'd help a friend out and check her out but this has got me a bit nervous. Does epoxy fall apart with a non purged motor!?! Or just old dirty oil?? Quote
BigRed350x Posted December 9, 2011 Report Posted December 9, 2011 You've got coolant or water in your oil. Probably a coolant-tube o-ring or water pump seal. Check your coolant level & see where its at. - Jared Quote

ginger Posted December 9, 2011 Report Posted December 9, 2011 You've got coolant or water in your oil. Probably a coolant-tube o-ring or water pump seal. Check your coolant level & see where its at. - Jared This happens from alcohol, it will make the motor sweat because of how cold it is entering the cylinders, and the bottom end sweat into the trans because of how cold it is. The sweat will make you think you have a coolant leak into the motor. This is one of the downsides to running alcohol. Quote

Will check the coolant level later today Quote

The sweat will make you think you have a coolant leak into the motor. This is one of the downsides to running alcohol. I've been running methanol for years and have never once had oil like that. The sweat you are referring to is condensation and forms on the outside of the engine. The amount of water or coolant required to turn the oil that color is a LOT more than you should ever see from condensation. - Jared Quote
tedd1 Posted December 10, 2011 Report Posted December 10, 2011 Agreed, alcohol has nothing to do with that... Quote

I do know E85 gas (85%) alcohol absorbs the water out of the air, some evo guys (turboed car) catch a noticeable amount of milky sludge similiar to this in there catch can, which is basically a filter to seperate the oil vapors out of the motor. I know these are 2 stroke and are nothing similiar but just saying alcohol pulls moisture out of the air. Either way it's prob a o-ring or seal letting coolant getting in the crankcase Quote
FREAKSHOW Posted December 19, 2011 Report Posted December 19, 2011 I agree with the fact that methanal can show signs as if you had coolant in the engine oil. I have ran it for years on UMP modfieds (dirt racecars). It seemed to show it worse when the engine was started and not let to run up to operating temp. It was nothing to start the engine let it run for say 5 minutes pull the valve covers and WOW alot of milky buildup on the bottom side of valve cover, yet if you stuck the valve cover back on with out cleaning it and ran it say 15 more minutes until it hit 175 or so, pull the same valve cover and it was gone, pull the pan drain plug and the oil was beutiful. But if you started the engine and just reved it up a few times and let it idle for a couple minutes to show off to your buddies say 3 times in one week, the engine oil can look like your picture. I do not run methanal on banshees but I would think the same would apply to the engine. Thus being said, We dont have oil in our crankcase, we have oil in our tranny. It appers from the picture that is what you are draining. If thats the case I would suspect the o-ring on the coolant tube that goes into the clutch cover or water pump seal. With all this said I am not a banshee expert. I do not know much about epoxied cases. So if the somehow epoxied a drain plug into the crankcase ( dont see why they would ) and you got that much oil out of the epoxied drain plug, My logic would say Did it ever run? Now last but not least, another cause could be water intrusion( and thats why I think you mentioned the epoxied case ) from rideing in water . If the epoxy was not sealing and allowing water to intrude into the engine, I would think you would have other issues long before you notcied this. Now if the epoxy was somehow envolved in sealing the tranny and it was degraded and let water in. I would suspect you would have an tranny leak while rideing. Keep in mind as I stated above I am not an expert on these and know nothing about epoxied cases. I just through this out there cuz I was trying to help clairify the alcohol and oil issue. Quote
tedd1 Posted December 19, 2011 Report Posted December 19, 2011 ... I do not run methanal on banshees... I do, and my oil does not and has never looked like that. Quote
FREAKSHOW Posted December 20, 2011 Report Posted December 20, 2011 I do, and my oil does not and has never looked like that. Thats because your oil is in your tranny and in the fuel tank, I was trying help clairify how methanol can turn ENGINE OIL into looking like it has coolant in it . Anyone who has run methanol on a 4 stroke engine has ran across this. I am not trying to bust anyones chops , I am just trying to help. Quote
Jereme6655 Posted December 20, 2011 Report Posted December 20, 2011 hahaha....i know i understood you there freakshow....i just think tedd wasnt paying attention to the face that you were clearly stating that you have never run alky in a bike where it had no actual engine oil for the crank to bathe in. i think he just thought you may have been typing one of the no nonsense arguements that some jack-wagon know-it-all morons out there throw around...

camatv Posted December 21, 2011 Report Posted December 21, 2011 if your concerned about epoxy, do a leak down test. if you think you have a coolant leak, try a coolant pressure tester. both will show issues easily and not have to guess.. Quote
