This motor won't keep run as #4 cylinder is no comperssion. Removed head cover and check valves condition.
Yellow circle is show #4 exhaust side camshaft and valve lifters.
This motor has 2 of valves each cylinder. Left side red circle valve lifter is up position as valve is close but Right side yellow circle valve lifter is stay down as valve is leave open (seized by rust) If valve is lightly seized, it will have a chance to back in to move valve after engine start but this motor didn't. Now this motor needs remove haed cylinder and service.
