How do you undercoat the valvetrain? I havent completly fixed the noise yet. I was told to tighten when cold or i could strip out the threads on aluminium head. So its still could be valve
LOL
Sorry wasn't to clear.
You were questioning about hearing the noise threw the valve cover, because they were powder coated!
My point was you could have used undercoating on the Valve Covers and still heard the valve train noise...... with a screwdriver, if it would have been in that area.
