How quickly can u burn a valve due to tight valve adjustment
Rebuild cylinder heads and put the engine back togetherDidn't see any sign of burned valves
Had misfire on cylinder 4 on and off. Blinking light turning into p0304
Check engine goes away on idle. Car was idling a little roughI drove around 100 miles after engine rebuild. Like a grandma..never reved passed 3000rpm
Valves were just a little tight. I needed to unscrew adjustment bold by about 90 degrees. Which is around .2mm travel. So basically had 0mm clearance instead of .28-.32mm recommended on exhaust valves
Thanks

Adjusted the valves. Engine super smooth. Most of them were too looseThe reason #4 was too tight is because I've installed the missing centering "pipe" or pin or tiny cylinder that is supposed to guide the rocker in perfect position. Before cylinder head work I did valve adjustment with slightly (2 mm ) skewed rocker axle.
I'll do compression test in few days.
