[QUOTE="MalcolmV8, post: 15260563, member: 8854"] Russ the car didn't blow smoke and still doesn't. If you watch the exhaust carefully on warm you see what appear to be wisps of steam but is actually smoke as it warms up. Very tricky. From my searching other gapless ring uses also note no smoking on the exhaust. Yet the exhaust, piston tops etc. are caked with black sooty burnt oil. I'm assuming it's the way it's getting by the rings it's not smoking? little bit at a time but consistently. I really don't know. I find way to many people having oil consumption issues with gapless rings who then go back to conventional and all issues are fixed to believe it's a honing issue. Dave (Juiced46) got back to me and said his motor was torn down and re-ringed 4 times in 2 months trying to solve the gapless ring oil burning fiasco and finally on the 5th time he went back to conventional gapped rings and everything was fixed. The valve stem seals they are saying will leak in vacuum conditions such as idle if they're pretty loose or deceleration when your vacuum is at its peak. [/QUOTE]
