I have never disassembled a rotary engine, so in my further thinking regarding the coolant drip from around the un-torqued tension bolt; perhaps someone would clarify something for me – does the tension bolt anywhere run through the cooling jacket?  I had assumed it did (why else are there seals under the bolt heads, but in looking at photos of housings, and cut-away views, it appears not.  Would this mean then that there is/was a leak somewhere between the coolant jacket and the bolt hole?

I found no sign of oil in coolant, or coolant in oil; but that probably does not mean there wasn’t some small amount undetected.

Al (next time I’ll build up my own engine – as though there will be a next time)
