Here’s a quick video of my leak down test.
CYLINDER 5 VIDEO LINK
I pressurized the cylinders again tonight and HEARD AND FELT air at the OIL FILL HOLE and INTAKE THROTTLE BODY. If I also have leaking intake valves, then the cylinder leak down test numbers will be falsely lowered.
The plan for the weekend is to run the engine for a while and test it again when warm. I want accurate info before I ask the engine builder to remedy the problems.
Here are the leak down numbers I got last night.
The engine was COLD when I tested. It was too late to warm the engine up, because I already had the valve cover off. I have some serious problems.
#1 = 91
#2 = 76
#3 = 94
#4 = 96
#5 = 62
#6 = 61
#7 = 91
#8 = 71
