Compression test results
#1 137psi
#2 145psi
#3 137psi
#4 140psi
#5 135psi
#6 130psi
#7 150psi
#8 140psi
These numbers seemed ok to me I was told not to worry if they were over 100psi. What had me concerned was the diff between #6 & #7. 20 psi seemed like a large diff. The truck is a 95 F150 351 with somewhere around 150K to my best guess. The engine was replaced once the OD has 218,000
