As title is stated, my Massey 205(S107) has a coolant leak. I figured it was just a water pump gasket but apon farther diagnosis I have found it isn't.
I don't have any manuals for it, so I am unsure what parts are what on the engine exactly; but it appears it is from the water pump housing or possibly a thermostat housing, at the top of the motor.
When looking at this housing there is a small hole(the culprit)(alil larger than pencil lead) at the bottom right(passenger)side of the actual housing. The top of the housing has a radiator hose, and out of the front of the housing is a pulley.
This small hole is where it leaks out of, runs down the center of the motor and of course to the ground.. I don't know how I recognized the difference in flow at different rpm, it just immediately caught my eye; when running the motor to find the leak.
At 1200RPM and below it leaks quite a bit, not steady flow but a good constant drip
At 1500+rpm it does not leak at all, obviously it's under a vacuum at this point?
And when I shut the motor down it'll drip a small amount out and then stop.
For several minutes at 1600rpms it did not drip at all.
Is this normal operation?
I haven't experienced this before, but I don't have much experience with older equipment; I am unfamiliar with any technology like that still being used today(if this is how it's manufactured)
I am sorry if this is "too" detailed; or hard to understand. I naturally have a hard time relaying what i am seeing for some reason....
Thanks for any help!
