I think your talking about the water pump . No they are not suppose to leak out the little weep hole . If it is then it should be replaced . (seals gone inside ) At least that's how it is in the automotive industry .
MF205 coolant leak.
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!

..yeah, as far as automotive goes; I replace my water pump with my timing belts every 100,000 miles so I've never risked one going bad, on my car if the water pump goes out it destroys the timing belt/thus destroying the motor "instantly"(vw TDI)I think your talking about the water pump . No they are not suppose to leak out the little weep hole . If it is then it should be replaced . (seals gone inside ) At least that's how it is in the automotive industry .
Sounds like what you say makes sense. Is that manufactured "weep hole" designed so when the seal inside goes bad it is obvious its time to replace?
If not what purpose does it serve?
Thanks for the quick reply; I'll now be searching for best places to purchase quality parts.

Well, the MF205 is fixed! Ordered a sparex water pump and gasket.
Less than $100 bucks and I'm set and ready to go. Installed it tonight with ease. Filled it with water to run it for now I'll get actual antifreeze within 2 weeks .
Whoever I ordered from, the cheapest around set a red flag to the credit card company they shut off the card I used. No loss if money; the part arrived the same day the letter arrived that they shut my card off haha.
Time to go mow!!!!
