Yeah, oil analysis might be good - but there was a cooler full of oil with a high concentration of valve guide material in it from the prior set of worn out valve guides, so the results might be skewed. I'll think about it. I did make sure to purge the oil cooler this time around. Used the lawn sprinkler method. Effective, but remarkably messy - I was too lazy to get some hose that fit over the cooler line, so once the air found its way around the remaining oil I got an oil volcano in my wheelhouse ...
Yep, 1000 miles on SAE30 break in oil. It was tough keeping the engine below 4000 RPM that long, but I managed. Seems to run cooler with the SAE30 than with the 20W50 by about 10 degF - odd.
I like the assembly lube + oil idea! Gonna give that a shot tomorrow evening - no time tonight unfortunately. I'll post back with results.
Thanks!
