Fork was recently acquired. Seems to run excellent everywhere. Idles good, good power, revs up good, etc. However, we have whitish smoke mostly at idle or that is when it is most noticeable. I notice a slight miss when it first fires but gets leveled out in maybe 20sec. Engine has 5000ish hours and has obvious blowby but not like an OMG rooster shooting out. We changed out the fuel because it smelled strange and figured either the fuel was really bad or someone juiced it up with crap. We were thinking along the lines of valve adjust, pump timing, etc but not looking to waste time on things that won't source the smoke problem. I really could be low compression but then again, valve clearance can certainly do that!
This is a 2H non turbo engine and cannot find much about them at all so no clue how often it needs the valves run.
the engine takes a little cranking on cold starts but I got to looking and the way the glows are wired, they only get power when the key is in the crank position. There is no other way currently, but that could be changed.
I tested the entire rail of glows together and showing them as a dead short or 0.0ohms to ground. I am unsure of what the resistance should be but at 24V, but that could be correct as I am figuring less than an ohm each maybe and I was testing all 6 together.

I have seen a few other machines with the white smoke symptoms turn out to be head gasket failure.
