Total Seal piston rings
I recently used Total Seal piston rings on an '87 mr2 engine rebuild. After 3k mi I still had excessive oil consumption and was getting serious carbon buildup. I tried a couple things to aid seating the rings but eventually tore it down again. The rings were shot. I had used a 200 grit hone instead of the required 300grit. Problem corrected - 3k mi later I have the same symptoms. Anyone have experience w/ TS rings on these engines before I tear it down again and go back to stock rings?
What was your ring end gap?
might not be the rings, valve guides could be worn letting oil through.
