All cylinders are perfect in compression test. All same number.
1,2,and 4 cylinders are perfect on leakdown.
#3 is weird. I plug it tester and goes to zero, complete leakage.
I hear air coming from #1 plug hole (NONE OTHERS). Rotate cam and stops leaking from #1 but still at zero. AFTER a minute or so, the damn thing fixes itself and gauge goes up to perfect <5% leakage.
Any wizards have the idea as to what is going on?
