wow RR, you really did one hell of a job on this thread!! Great pictures, great analysis.
I recently switched to 5w-30 in preperation for summer, might need to consider future changes.

That's awesome...maybe he can help clean up the shitty rep that mazda's reman program has generated for itself over the last 7-8 years or so going back to the california plant closure.

I suspect that's the idea in this case with Mazda taking control of the reman process from an apparent contractor operation.
BTW, check out his recent initial posting:

Premix!
Wow, when I look at those pictures it looks to me like this engine may have been run low on oil. I would encourage you guys who want your engine to last to put synthetic premix into your gas, you can get it from the rotary engine section at your local Walmart. Clearly they can't program enough oil injection to keep these engines gong a long time. The premix being atomized with the fuel will distribute itself inside the engine much better than the oil injection anyway.

Agree, the Amsoil Saber Pro is the only and best Pre-Mix to use.
Just not in the ratio's they suggest for a 2 stroke engine ..BUT.

Do yall think it makes a difference WHERE the oil comes into the engine at. The actual physical location---at tdc, on the intake, before the trailing? Think about it---Pre mix doesn't stay in the engine long unless you mix in a concentration that is large enough. So unless that is done--we need a better lube source.

As stated above the additional port in the '09 seems to be consistent with this theory.

1st, thanks for taking the time to post this thread and attach those amazing pics.
2nd, this is depressing a little bit.
3rd, it looks the great oil weight controversy continues, unabated.

great thread, thanks for sharing your experience...
one thing i've always wondered - when you put a rotor into the housing, how do you keep the seals on the underside of the rotor (side, cutoff, that corner bit of the apex, etc) from falling out?

I usually build my rotors 'dry", without coating everything with a slop load of vaseline etc. like some builders. Not that it would be detrimental, it just seems messy and wasteful to me.
The seals usually just kind of sit there unless you are moving the rotor around quickly or shaking it. Before I had ever built an engine, I wondered the same thing...but once you handle the parts, you will realize it is not really an issue. Sometimes you find a particular seal that wants to fall out of it's slot, and in this case yes I do use a small amount of vaseline to help hold it in place until the engine is assembled. This happens on maybe 1 out of 20 engines, though.
