I am so glad I decided to get Mazda OEM ones......

 

dude, thats weird, they look twisted?

 

its like the back and forth, of heating and cooling physically broke em?

 

It almost looks as if they've been melted. Man, this sucks...makes me feel wonderful that these are in my motor right now....

 

Just try and keep it under 4k rpms.

 

Heh...too late on that one.

 

Unless you know otherwise Luke, I don't think I used them in your motor this go-around. If I did, yours was the very last one that had them.

Unfortunately, I believe we did use these this time as well as the first time. I purchased the RA O-Ring kit and sent it to you for this last build. I believe they shipped it directly to you.



I think you made this thread shortly after I had talked with you about the coolant leak that I had because we originally thought this was the case for me, but mine turned out to be the o-rings on the LIM.



So far, my motor has shown no signs of bad coolant rings, but I'm sure it's just a matter of time.

 

It looks like a material failure to me. I think it would be more localized if it was pinched, or even mishandled at some point. But the split covers so much of the seal, and its not even in the spots where it would make sense to fail like that, such as just below the exhaust port, and at the seam up by the intake port.



On the same note, I still have yet to have a coolant seal failure with these seals, aside from one engine of mine that was grossly overheated on a handful of occasions. But even that engine didnt split the seals like yours.

 

I just ran into this lovely issue. I think mazdatrix had somone clean behind the shelf and that somone

found an anchient set of inner seals. Was cleanin off the hylomar before layin the housing down and noticed this. Walked over to the package to find 2 others like it.



I whish they had dates on this stuff!
