OK Kelly,

I have the same 4 sizes listed now.

PFA/silicone is to be specified for ordering purposes.

O-ring cross section is determined by the depth of the groove which for the 2 larger rings is .063”. A .063” groove can be infinitely wide and still use the same cross section o-ring as the grooves in the engine as long as the depth is the same.

Thanks,

Jeff Chrysler

Jeff,

That is welcome news.......Apparently from all reports from users the following

are the correct sizes for the smaller oil seal rings:

The proper oil O-ring sizes are:

0.093" section 4.68 inch ID $4.59 each
0.118" section 4.33 inch ID $4.47

The coolent O-ring sizes are:

0.093" section 11.190 ID $8.33

0.093" section 8.950 ID $6.60
