After thorough analysys I came to the following conclusions:
The leak may occur in these areas: -water pump seal (this is Cobra and I have no detailed info about it, I need to study it in depth, but it seems least likely) -head gasket leak (checked and eliminated) -cracked block (inspected it and haven't noticed anything unusual, still need to do it again in depth, for now I see it as unlikely cause) -leaking intake seal (even though I checked it and did not notice anything suspect it seems to be the most likely reason considering the amount of water) -raiser leak (strangely the engine never stalled which would indicate raiser/manifold issue, the other reason it is less likely is that there is so much water getting into the crankcase that I wonder how would it be possible for the cylinder with a healthy head gasket to pass water into the crankcase - if not through the valves (unlikely) then how? the only answer would be a cracked block). Don't know if this is correct but I'm down to either cracked block ot intake gasket. Considering, the engine ran fine and there are no indications of any cracks... it looks like the intake dripping straight into the valley and from there directly into the crankcase, looks quite logical. So what do you guys think? "Proxy" wrote in message e.rogers.com... OK, guys here is the scoop. I took the head off on the even side that was suspected of water leak. Head gasket in perfect condition, same with intake manifold, both sides. Cylinders inside OK no issue, no rust, scuffs or anything suspect. There are rust residues on the top of the cylinder (inside the head) and valves are quite rusty. No. 4 has most rust although as I said cylinder walls are OK, no rust. Seemes like compression test did not lie and the undertaking so far has rendered zero results. It was simply unnecessary. There has to be another point of water entry. I'm not even thinking about takeing the other head off as compression was perfect on all cylinders. I've redone raisers last year (new gaskets, throughly cleaned, refinished contact surfaces) but maybe I'd have to do it again. Still looking for ideas.... Any input appreciated. "Mikkilla" wrote in message ... 1.) have you checked the oil. if you have a blown head gasket you will end up with water in the oil see if its milky in color on the dip stick. 2.) Your impeller might not be up to par to keep the engine cool. What was the engine temp? 3.) was the water coming out at a study flow from the exhaust or was it all steam and not water or very little? 4.) the water "spray" you got if a very good chance it came from the water that got in to a uncovered Carb. Careful there you might have something rusted up in the intake area. |
