Anthony,
No problems at all-here's why.
We do use the complete set from Total Seal (including
oil stack)for all our engine families. Our honing process is an equal partner in the ring seal area. Torque plate, speed, duration and grit have been refined to the point where sealing happens quickly. Our builders square each ring in the bore, measure and file fit to our preferred spec.
Remember, each engine is run-in and dyno-tested within the first minutes of it's "life". From three to eight full throttle pulls to make their power numbers. Street engines to about 6300, drags to 72 or 7300 RPM. We always check for visible smoke, leak down and compression test. Also the A/F Ratio sensors for each cylinder warn us if there's a problem.
So they're good when they leave us or they don't leave. We've had NO warranty complaints about ring-related problems and that applies to street engines over a two year span.
I'm just saying that what WE do with Total Seals has been successful. Possibly anybodys rings would be fine with our procedures. Your experience with them may be different and valid for the prodedures you use.
