04 2.0L non turbo, I just replaced the head gastket and bolted the head back on and yet, cylinder 4 still leaks. It won't hold any air.

I feel the air coming up through the other holes around #4 like the oil holes.

The first 3 cylinders are fine, I don't see any cracks on #4, the valves look to be seated fully, not sure what is going on.

The piston looks fine, no damage on the cylinder walls.

I see a ton of used heads for sale, has anyone had good luck with used head or should I just go new/rebuilt?

Can someone also confirm the torque is 50ft lbs?


Thanks!

 

I just cleaned up the valves with a wirewheel and I don't see any cracks, so not I am scratching my own head!
