Iím just trying to figure out what, exactly, I should know and what you have done to successfully get the compression and the low oil consumption where it should be after break-in on a rebuild 22.
What honing tool did you use?
The three stone floating kind and a hand drill.
What manufacturer of pistons and rings did you install?
oem, NPR, whatever Engiinbuilder sent with the pistons back in the '00's, and whatever came with the rebuild kit from one of the Supra suppliers for my 7mgte.
What Ra did you end up with?
Unknown, the hone I use is older than I am, it dates back to at least the mid '50's-early '60's when my Dad was building hotrods and drag cars, possibly as old the mid '30's when my Grandfather worked as a mechanic for Cadillac. Best guess would be it is about 220grit, which appears to be an RA somewhere between 28-35.
How did you measure the Ra?
What piston to cylinder clearance did you measure?
Never have, just with the blocks that didn't need to be bored, I just bought the rings needed for the cylinder, and hand honed them to seat the new rings, looking at some vids on Youtube, at most this is about as aggressive as I have gone.
Having done some reading now, and compared to what I have experienced, either I am the "blind squirrel" with each hand hone I have done, or measuring the RA and piston clearance isn't as important with a re-ring on older engines as it is when the cylinders have been bored, or with modern engines and the tighter tolerances due to fuel economy and emissions requirements.
