Questions ???
Stamped # on the piston rods crank ends do not match.
Cylinder
#1 #2 #3 #4
1-2 1-2 1-1 1-1.
Can anyone enlighten what the stamps mean?
Piston oilers are supposed to be 10-30 degrees from vertical. Mine appear 5-8 degrees at most!
Another piece of the puzzle?
Now on cyl 2 and 3 with low compression, I coincidentally have heat like marks on the crank pin. Caused by blow by? Should I check crankshaft for straightness? Be concerned about annealing/heat treatment effects?
