blown coolant seal....*pics*
Recently i had my engine rebuilt and upon breakdown we noticed that my coolant seal on my front housing had completrly failed. there was a little drop in compression but not bad
My symptoms:
excessive white smoke upon startup
Sound like a running facuet on my passenger side firewall
drop in idle when the car was warm
also the engine was ver weak.
here are some pics and they can hopefully help someone daignose there problem.

Very cool. For people who rebuild engines this is probably very old hat, but for people who don't know know rotaries it's good to see.
Are all of those black sections of o-ring shot?
Do you have full res pics? If you want I can host them for you. In any case, it would be cool to see in tighter detail.

The cause of this is periodic overheating due to the inadequate stock cooling system and Mazda setting the overheat function on the stock ECU way too high. Oh Yeah, and a water temp gauge that ruins your engine by the time it shows overheating.
I do not know of anyone here in Houston having this failure after fixing these problems and running a PFC.

when i bought my car i found out later that i had a clogged cat. yes all those black marks is the burnt coolant seal 
If you have a clogged that you know you of replce it immediately
My apex seals were perfectly fine. Thanks god or else my rebuild would have cost ALOT! more.

I've heard them mentioned. There are some very very heavy duty seals available. Just alot more costly, but could be worth the effort for a "bullet proof" rotary.

Charlie,
Here's the link to your pages showing pics of the entire breakdown, rebuild and install, just in case you lost it.

I'm resurrecting this ****' because of a stupid question: are the O Rings in rebuild kits the coolant seals?
I've got smoke at startup, I've had to refill my coolant with no apparent leaks, and I started my engine with the rad cap off, but I cut the engine before the coolant overflowed (maybe I put too much coolant in?). These sound like signs of a blown coolant seal so I'm researching engine rebuild options.

I'm not so sure that it's water condensation--I've done some searching and even saw a video between the two and I wouldn't doubt that it could be bad coolant seals. What further pushes this suspicion was the fact that I had the "Add Coolant" alarm buzz without any visible leaks. I'm also experiencing an unsteady idle, in that it fluctuates between 1100-1400 RPMs. I really need to get my FD checked out.
Can anybody answer my question above regarding O Rings and Coolant seals? Are they the same thing?
