Tom,
Don't know how much of your clean motor to credit to the glyptol, or just
the fact that (I'm sure) you used good quality oil and changed it
frequently. However, I too have used glyptol for this purpose with good
results. I would like to caution anyone considering painting the insides of
their engine DO NOT USE RED OXIDE PRIMER!!!, e.g., rustoleum. The hot oil
slowly dissolves the red oxide, which of course is an abrasive, and eats
away at the friction surfaces. Also, never use glass bead or sand media to
clean any interior engine surface (e.g., the underside of the intake
manifold, etc.) I've learned these and other lessons the hard way. More
than any previous engine I've built, my current engine's oil stays clean
and my solid lifter adjustments remain stable for long periods which I
attribute to reduction of wear through cleanliness of assembly and sealing
of the cast iron surfaces with glyptol.
Regards,
