They say bore X .0065 for top ring gap. In my case that would be 4.120 X .0065 which is 0.02678. My question is how imperative is it that I tear the engine down asap? It's been this way for probably 1,000 miles. |
If you don't set the correct ring gap on that top ring you could butt the ring, tear up your bore and destroy your piston. It's up to you if you want to take that risk. If it were my engine I wouldn't run it another minute until I fixed it. I have no idea what the engine builder was thinking but it sounds like he had his head in a dark place. I would set them at .027 and drive it like you stole it with no fear.
