Did the warm/hot engine test again. This time with throttle body, oil dipstick and coolant cap open.
None of the cylinder showed any air noise from throttle body or the coolant fill (no bubbles either). Oil dipstick had a slight air hiss as before. I understand this is normal. Exhaust had a air noise echo. Very faint but could hear it like before.
Leak percentages were same as before but cylinder 2 and 5 were lower. This time the engine was much hotter than earlier though. Others were about same or lower. So am good? No engine teardown? I was reallt hoping for a drop and tinkering.

Guess it has to wait for another day.
I guess i don't need to do a DIY. What PAULV attached is pretty straight forward.
