Message This is my first build on a vg motor doing a na to tt swap. I had the motor bored over .040 and installed weiseco pistons, had machine shop do a valve job on used TT heads. I have fuel, spark and good compression on 4/6 cyl.
cyl#1 150psi
cyl#2 150psi
cyl#3 160psi
cyl#4 150psi
cyl#5 0psi with and without oil on rings
cyl#6 0psi with and without oil on rings.
By the test i would assume that it this is a valvetrain issue. ANY help would be nice.
Thanks
