Wrote Rusty about this already but yes, the 3/8" spec on chain slack is not right.  Never seen one with that little even on new engine.  1/2" is good..

Congratulations, Rusty. 
 
The first one is always the hardest.  Yes!, number 2 rebuild is much easier/quicker (don't ask me how I know).  Well, - OK, I too my first rebuild of my current 91 block and after about 3-4 hours had it back in the airplane, pour coolant in and sat there sobbing as it leaked out the block.  Another hour or so to take it back off, cart it back to the shop and 15 minutes to fix the problem, then back to the aircraft, etc.   Next time I swore I would pour water in back at the shop to check for leaks - then I'd probably complain about water leaking all over me as I installed it.
 
I agree I don't think the hylomar will hurt anything (as long as you don't have fist size gobs remaining in the chamber {:>).   I found the same thing on a new oil chain myself - my old one had perhaps a tiny bit more sag, but the new one didn't seem to meet the specs called for. Been flying with it for 260 hours, so far.

Subject: [FlyRotary] Engine assembled

Greetings,

 

I put the engine back together yesterday with the help of Bruce’s excellent video.  Seems to be glued together more than bolted.  Spent way more time with a brush than a wrench.  Everything went reasonably well with a couple exceptions.  My overhaul kit was missing the corner seal springs, and I didn’t realize that the oil seal springs weren’t included in the kit, so I had to use springs from the original assembly.   I also had to use one corner seal, because I managed to break one (don’t ask).  

 

I still measure ½” of slop on the new oil chain, which is the same as the one I took off. According to the video, that’s too much slop, so I have a message into Tracy and Bruce about it.  I'm guessing this has to be normal, but it was a good place to stop last night, and I'll wait for an answer before putting the front cover on. 

 

The engine has a K spacer, and .002” end play.  Turning the engine shows that everything seems to work, and that I got too much Hylomar on the housings.  It seems to be collected by the apex seals, and I’ve wiped off all I can get to through the exhaust ports.  Shouldn’t hurt anything.  When I get an answer on the oil chain, I’ll close up the front cover.  Overall, I’m convinced it will run, and I’m pretty happy with my first rebuild.    

 

Rusty (still far from being back in the air)
