Fwiw, my Cruzin rings seated with no problems at all.Got about 45 mi or so and the rings still haven’t sealed I can definitely tell the difference in the ring sets the ones I got from Cruznimage gave me problems from the beginning, thus the OEM set that I quick ordered when one of the original sets got messed up. OEM side is not smoking as much but still doing it also. Had a good crosshatch in my cylinders.Any suggestions other than Ajax or Baking soda? Lol
Factory spec on the cyl's is 2.9528 +.0008 -0.cylinder and it mic’d at 2.950
First and second ring gap is 8 to 16 thou. Yours is almost twice that.Ring gap was .028
No, not close. That would give you about 15 thou skirt clearance. Book max is .0022" .....though it's normally accepted practice to go as high as .004" when reusing old pistons.I checked the cylinder and it mic’d at 2.950 and the piston was 2.935 so not being totally savvy with all that I’m assuming that’s pretty close.
I’m just trying to get this old girl on the road and reliable. I had no issue pulling that engine back out and trying again. I had minimal issues building my ‘72 engine so maybe it’s sometimes better to be lucky than good.Factory spec on the cyl's is 2.9528 +.0008 -0.
I suspect your measurement's off. No way they shrunk smaller'n what the factory cut 'em to.
Geez, I only missed by .0028……

Could that have been the issue with that side smoking and lack of compression?
