My Dad's 03 Manual Vinson has milky oil. He changed oil and ran it everyday for a week being sure to keep it running for an hour each time. Fresh oil is getting milky again..
Thinking it's the water pump seal. Has anyone here successfully changed the seal or even replaced the whole pump assembly?

Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00. It's been sitting outside with no carburetor on it for about a year. Its rusty, missing some parts, wiring is all cut up and spliced etc. No seat, no racks but the plastic is all there minus the headlight housing. Anyway, who can pass up a $40.00 quad right? I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water. I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine. I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark. Did a quick compression test, 70 lbs. Wet test bumped it up to 90. Ok, so rings and cylinder washed out with water for a year, not too surprised. I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show it's got life. Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either. The compression is now around 60.
Anyway, my question is....is it worth it to try to get this thing going? I tore the top end down today and the cam and one of the rockers is pretty worn. I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well. Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again. Much less just to make it run and use as-is but I won't really like it until it's right. I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much. I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down? I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
I'll get some pictures today if anyone want to see them.
went to sell this guy my bike and on his test drive he just took off and never came back.

Let me know what you guys think. Just registered as a member here and thought I'd bring something to the table. I probably have around 50 or so ATV how-to videos on my channel. Please let me know what you think!

What's the best way to fix this?...
Best idea so far is to clean it all up, sand the bottom side real good and find a piece of durable plastic I can shape and form to the bottom, and sand it as well. Then hold it all together somehow and epoxy the formed plastic to the bottom side. After curing, drill holes on both sides of the crack and thread wire through like shoelaces for support, pull tight and tie off.
Seems like I read about some kind of goop you could use in this situation but I forget what it was called. I believe it would take the place of the epoxy.
Right now I need advice on what kind of plastic to use and how to source it, as well as what kind of epoxy.
I'm all ears.
Does anyone know if my utv has a thermostat and if so the location of it? Thank you
