leathermang - yep, I use Delo 400 15W40 exclusively

jt20 - this is true; I only drove it for about 40 minutes total after the valve adjustment; would this be enough to dislodge something? The intake valves were sort of borderline, but I remember the exhaust valves being quite tight. Before the adjustment, the feeler gauge did not fit through several of the gaps.

Scott - you're quite right; maybe "tightened the crap out of it" was poor wording. It's hard to describe exactly how tight I made them, but they are together with about the same force as they were when I started. I am always conscious of the threads and making sure things are torqued properly.
