Anti-freeze?
What's that? Some new fangled chemo-majik?
Actually, I don't entirely trust my engine to hold all it's water. During the initial rebuild I found water had leaked into the sump, via the cylinder studs. Those studs are thru bored into the case, and you can see them when the crankcase door if off.
If the stud doesn't have a good sealant on it, or the cylinder base gasket (paper) leaks, the water ends up in the oil.
That's only moderately irritating if you check for it before starting, but antifreeze in the oil will strip the babbit right off the bearings, and that's more than irritating to me.
I don't run this engine very often, it's my back up gen for the house. when the power goes out, I go thru the whole Rig-A-Marole, open crankcase, squirt oil on the crank, rods & cam, inspect for water, and prime the oil pump before I start it.
I don't mind the drill, but I haven't really wanted to use anitfreeze, so I heat it in freezing weather. Plus it's easier to start - although I do have an intake air preheater.
I was just wondering if any of you guys uses engine pre-heat and how you do it?
Maybe if it still hasn't leaked by next year I'll update and add some antifreeze; as an experiment so to speak....
