George,

I found my receipt from Creavy Seal Co. Unfortunately, it is only for one coolant seal, and both oil seals.

As for the outer coolant = seal… Originally I ordered a set of SIL .093 – 11.340 ID o-rings. These = proved to be too big and I had to send them back. Note that 11.340 minus .090 = is 11.230… the correct size. I had given them a size based on = CL, not ID. So, be sure you’re on the same page when ordering these things. After a few emails to Jeff Chrysler, we got it right on = the re-order with these numbers… SIL .093 = – 11.230. These fit perfectly. I can find no records for = what I ordered on the inner coolant seals. Here is an email I sent to = Jeff Chrysler at Creavy Seal after fit-checking the new outer coolant = o-rings.

Hi Jeff,

The reworked TES o-rings fit perfect. Final dimension for = the outer coolant o-rings is .093 x 11.230" ID. Thank you so much = for all your help. I can start putting my engine back together = now. I have passed this information along to Paul Lamar as well. This = size should work for all 13B and 20B engines, but you may want to verify size before = using it for the new Renesis engines.

Thanks again for your assistance,

Mark Steitle

The information for the two oil = seals are SIL .093 – 4.680 ID, and SIL .118 – 4.330 = ID.

Hope this = helps,

Mark

Thank the Lord for small = mercies!

At least we have a consensus on that, I was thinking = Oh No! not another variation.

Kelly,

On second though, I believe = you’re right and I was wrong. Creavy works with ID, not CL. =

Cary,

Thanks for the input.......What we are trying to do is = get final and absolute

numbers on the sizes required........One of the first = requirements is for all to

be on the same page with measurements.......Previous reports = have shown

ID's , OD's , Center diameter and/or total length........I seem to remember reading

a previous post that "Creavey" preferred working with = a ID measurement

but Mark just posted that the Center diameter is what they use = ?? Bottom

line we all need to be on the same page among ourselves and with "Creavey".

FWIW
