There was a large/deep grrove in the crankshaft seal area, so I installed a seal surface repair sleeve.

The ring filer worked fine - it made short work of the job. <img src="/forums/images/graemlins/kewl.gif" alt="" /> All top rings are gapped at .018", the 2nd rings are at .020" and the oil rings have at least .010". The pistons are installed, but the piston/deck clearances aren't as good as I'd like:

#1 = .019"
#2 = .017"
#3 = .020"
#4 = .018"
#5 = .018"
#6 = .016"



The dealer tells me that MLS gaskets are not available from Mitsubishi - not sure if he knows what he's talking about, though. So, I ordered some Nippon-Reinz MLS gaskets - should be here in a couple of days. I just hope they're at least .050" thick..... if so, that'll give me a quench height of .030" minimum - not great, but it should run fine. I don't like the piston/deck variances, but I don't want to grind the crank/resize the rods and/or mill the piston tops at this point. Aside from the quench distance, the variances are better than the original engine, so I'm going to run it like it is.

If I ever build another blower engine, I'll sure start by indexing the crank and use custom rods..... in hindsight, it would make a much better engine than what I see with (some) factory parts.
