I'm doing my first engine rebuild, thus far nothing appears to be going right. I'm about to gap my piston rings and am wondering if I have to gap the wave ring that sits between the oil rings? I'm unsure on this and I can't find anything about it even on youtube. It seem way to tight for thermal expansion in my eye's..... I'm very leary about proceeding
Pistons I'm running are NPR cast .20 over bore
Not to mention the fact the humidities so high my blocks rusting faster then I can build it.
Pics of cylinder 4 12 hours of sitting in my garage after preping for assembly.
Also wondering if the stock ring gap specs are what I should be following? (I assume so...)
Standard value:
No. 1 0.25-0.40 mm (.0098-.0157 in.)
No.2 0.20-0.35 mm (.0079-.0138 in.)
Oil 0.20-0.70 mm (.0079-.0276 in.)
Limit:
No. 1, No.2 0.8 mm (.031 in.)
Oil 1.0 mm (.039 in.)
