The engine itself has never had any series or characteristic HG issues (like Vulcans, NEON's, etc.)
You don't show any Pb or radical numbers that typically (every time I've seen it ) accompany coolant ingress into the oil.
I don't know how you can say that Gary. Yeah, his wear does look very good, but he still has a coolant issue. Na and K are elevated, glycol was detected, and he noticed his overflow was down an inch.
There's very limited coolant passages on this engine, so whether it's a HG, cracked head, or cracked block, there is something amiss. It doesn't seem to affect wear at this time, but summer is here and personally I would try to find the source before next winter. God only knows that stuff breaks in the dead of winter! If he can get by with a coolant tab, that's cool (no pun..), but for the $40+/- dollars and a few hours of time, I would like at least some piece of mind. It's not the crack prone head, and the blocks are pretty stout, so the HG is my best edumacated guess as to the cause. Just my $.02 guys.
Points acknowledged.
I'd probably spend another $20 running nek'id ..with nothing done to see what shows up next round.
Yes, the HG is surely the cheapest and most easily fixed source of coolant contamination on this engine. If it was any other engine ..something with a transverse V or more modern design, it would be very expensive in comparison.
