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

   Chuck Dunlap is currently flying with TES O-rings supplied to him

by Paul Lamar........

Thanks Kelly. Finally, I don't see an order option on Creavey's page, but I presume they do sell retail, to individuals if you call them. Is that correct? Assuming these work OK in practice, I don't see any other downside. Now we just need to get Lynn, or Leon to install a set of these in a race engine for a real test :-)

Also, I noticed that the Mazdatrix site seems to agree that the coolant o-rings are the same from 86 on. If you click on the actual seal part number, the description says "86- ON" & "(+RX8)".   The oil seals seem to be different between the 13B and Renesis, which I would have expected.

Cheers,

Rusty
