Tom, is that right? I thought 400 was normal. Spec is 26-32 bar which is 377-464 psi with 3 bar or 43 psi difference between cylinders. Min is 18 bar or 261 psi.

Chain, maybe a leakdown test to provide more info. That much spread isn't good.

Matt, I don't have V8 specs. For a similar vintage 300E normal is 175 psi, 110 psi is low, difference should be within 20 psi. Specs for a 560 won't be much different.
