Cm870 low oil pressure

[tree98]

Did you pressurize the coolant and look for leaks around the liners before you took the head off?? For all you know you have a liner starting to sink right now. If so you'll be tearing back into it in short order AND you'll be replacing the head a second time because the liner will dance around and wear a groove in it. You aren't going to save any money by half assing it, many of us can attest to that!
