As far as I know, there is no difference in the top and bottom rails, or scrapers. But, the question is, did you set the gaps correctly?
The expander ring should be set with the gap over one end of the piston pin, and the top rail is then put on the piston with the gap set at 10 o'clock( with 12 o'clock the gap of the expander ring) and the bottom rail is then put on and the gap set at 4 o'clock.
Also and just as important, is that the ends of the expander ring spacer ends cannot overlap, but must only butt together. This needs to be double checked after installing the side rails as you can disturb the expander ring spacers when you are installing them...
If the engine is pumping out that much oil, I guess it is entirely possible the oil ring end gaps aren't set correctly and that is the problem. I know you didn't want to hear that.....![]()
If you aren't sure, you might be better off to take it back down and double check now instead of taking the chance of damaging the bore or pistons....![]()
