I will say that if I ever tear my engine down again, I will definitely have the rotors ceramic coated. It doesn't take all that long, especially considering that you have plenty of other things to do with clean up, checking wear, etc. I think that even 10 degrees lower is pretty significant, and pressing out the old rotor bearings and pressing in 2 new ones is a pretty easy and fast thing as well. BTW, I didn't notice any of my tension bolts being bend, but then I didn't roll them around looking at them all that closely either. If any were bent, it wasn't enough to see by casual examination.

There was quite a bit of rust still in the water passages on the front housing, and I spent quite a bit of time scraping that out.

I've also floundered a bit on the ceramic coating for the rotors. While I'm sure this would help the oil temps, I just don't think I'm going to do it now. Unfortunately, most people that do the coating, also change something else in the process (as I would be), so it's hard to say just how effective the coating is. At best, I can't imagine it lowering the oil temp more than maybe 10 degrees, which is nice, but not essential. Basically, I don't want to take the time to ship the rotors off, and also don't want to take the chance of having them ruin the bearings in my brand new rotors. I'm going to hope that my main oil temp problem is like Al has said so many times- I needed a real oil cooler. I'll have a nice one now, and should be OK. By mid week, I should have everything I need to finish the engine. I'll probably spend next weekend porting the new housings to match the ruined ones, and I'll plan to put the engine back together the following weekend. Still lots to do before it gets back in the air, and as I KNEW would happen, I just got my hanger eviction notice in the mail yesterday afternoon. I'm "supposed" to have everything out before the end of the week. Fortunately, this is just the county's way of saying they won't be responsible for damage. The guys who are actually doing the work said all we need to do is give them access to the walls, so I just need to move everything to the middle of the hanger. They've already fixed the roof, so it doesn't rain in there anymore, but stuff could still get wet when the walls are removed. I'll be heading to Lowe's in a while, to buy a bunch of Rubbermaid storage containers, and will pack everything in those, and pile it in the middle of the hanger around the plane. With all that crap in the way, I won't be able to work on the plane until they get done, which could be weeks from now. Fortunately, I'll have the engine work to keep me occupied.
