I just got my engine back from the machine shop. I am very concerned about these measurements they took on my cylinder bores and piston diamaters.
Tell me what you make of these numbers:
Cylinder#1
Bore=4.0223
Piston=3.9987
Clearance=.0236
Cylinder#2
Bore=4.002
Piston=3.9995
Clearance=.0025
Cylinder#3
Bore=4.0022
Piston=4.00
Clearance=.0022
Cylinder#4
Bore=4.0026
Piston=3.9988
Clearance=.0038
Cylinder#5
Bore=4.0021
Piston=3.9989
Clearance=.0032
Cylinder#6
Bore=4.002
Piston=3.9997
Clearance=.0023
Cylinder#7
Bore=4.0027
Piston=3.999
Clearance=.0037
Cylinder#8
Bore=4.0023
Piston=3.9978
Clearance=.0049
Have you guys ever seen numbers like these? Did I do my math right? If I did then I fear the worst...
My book says Piston-to-cylinder bore clearance = .0034 to .0042
Those numbers up there are just crazy, some of them are .02 off!
This can't be normal.... Can it?
The engine was super clean when I tore it down, not driven hard, only 77,000 original miles on it...
