Although it requires removal of the
valve cover.........
An even simpler and already fabricated tool, is using a large
Crescent wrench on one of the cam lobes! (Picture available
for anyone interested!)
My problem is, I have an "adjustable cam sprocket", so the
normal access to the legs of the sprocket is not there!
I've been using the Crescent wrench method for years!
Haven't marred a cam lobe yet!
