Here is my situation.
#1 9% leak down 120# compression
#2 9% leak down 120# compression
#3 6% leak down 122# compression
#4 4% leak down 126# compression
#1 and 2 i can hear leaking in adjacent cylinders, also in the tail pipe. #1 i can hear slightly in the intake. 3 and 4 nothing in the intake or tail pipe but hear a very slight leakage into the sump.
Car smokes blue black. it is running rich as i am still sorting SU needles
Opinions?
what is it with these 1500 heads? i went thru three last summer before i found a good one for a different project. Both heads i had checked were cracked between the valves on # one cylinder. judging from my readings above i may find the same situation when i pull this head.
