Probably answered my own question but a few weeks ago went out for a 60 min cruise, all ran great, drove it hard but not over 3500 rpm at shifts. Parked it in the garage.
Next morning fired it up and immediately heard a valve ticking. Shut it down and decided to change the oil even tho there was only about 1500 miles from a change the previous year (Royal Purple + ZDDP)
Fired it back up and heard a miss. Checked plugs wires etc but all firing, isolated it to the #4 cylinder (2nd on pass side).
Did a quick compression test got 90lb. (will do either leakdown or air test tonight or tomorrow nite). pulled the valve cover and poured a bit of seafoam on the valves and down the lifter pushrod. Next day pulled coil wire turned it over and all seemed to be moving fine.
I'm thinking (due to the ticking that is now stopped) a lifter or valve may have stuck, the ticking was it hitting the piston slightly and it became bent.
The air test will tell which one or leakdown the rings which I doubt it is (engine only has about 7500 miles on it tops) but it looks like the head comes off...
At my old house my garage was partially heated. Its been in my new shop for two "winters" and I heat it only when using it. This year I did notice the oil was a bit milky but after running it for 20 minutes it cleared right up. Ya think maybe some condensation built up and caused a sticky wicket? I was a bit long between winter startups....3-4 weeks sometimes...
Maybe use some oil additive before putting it up to keep the parts coated...??
Thoughts and [censored] kickings welcome, I'm pissed that through some of the best weather all year it has now sat
