rocker/valve cover air leak opinion

[USMCgetsome]

Ok so i looked all over and found that there is a massive vaccum air leak at the top of the left hand valve/rocker cover. I figured it was the fuel injectors going into the block but i can distinctively hear the leak at the cover. I'd have it pulled off already but i'm waiting on the engine to cool off. think this is gonna solve the combustion problem in the first 2 cylinders?

This leak is at the very front of the left hand valve/rocker cover on it's left hand front position. There is definitely a seal issue there. I'll have it pulled by tomorrow and have pics to show.

Maybe it is the intake manifold to head seal?

i'll double check but i can hear it loudly at the rocker/valve cover.

does it have a pulse or is it a steady leak?

[USMCgetsome]

steady.

see if your pcv rattles, if its stuck shut crank case pressure could be at fault
