I bought a 210 that had been sitting 3-4yrs. I went to replace valve cover gasket and when I removed valve cover the valve cover was quite rusty and the valve train is full of rust particle that have dropped from the valve cover. I plowed with it this summer and there is no slime under the valve cover. Looking for suggestions on how to clean it up. I don't think I'm using any antifreeze. Any help would be appreciated.

There's probably no good way to do this. I'd bead blast the inside of the valve cover, clean it up and set it aside. Next, I'd probably remove the rocker arm shaft assembly (after disconnecting the oil lines) and set if off to the side for wire brush cleaning and compressed air and maybe a complete teardown, then clean and reassemble. Pull out the pushrods and organizing them to go right back where they came from. Plug each head bolt hole to keep dirt and oil from migrating into them. Plug push rod holes with rags and blow off the top of the head with compressed air and brake kleen. Reassemble clean and oiled up parts. Use a long air tube to blow out each head bolt hole and use light grease on the head bolt threads. Tappets will be the same as they were before if you kept the push rods where they were before. Start engine and let idle for a few minutes to allow the engine oil filters to catch any debris. Make sure the rocker arms are getting oil !!!

My D15 had lots of ice buildup there when I bought it.
I would
just wire wheel the valve cover. Plug holes as suggested. Take shop
vac and pick and get all the particles you can. Break clean and
compressed air. Put it back together, change oi and filter and let her
rip.
It sounds like the thing is not getting up to temp to evap out the water when used. Thermostat OK?

I always do it like Dave says. By being careful. You can use the shop vac with corner end on it and it will get the crevices cleaned out. You can plug the holes as you go, just move your rag as you go. House vac will work too if the little woman doesn't catch you.
