The two materials don't adhere to each other too well.

One side note...
Mazda recommends putting the "seam" of the inner water jacket o-ring seal toward the intake port.
At this location, this is the area where that seal sees the least amount of stress - heat and pressure.
I noticed that you got your seams in approximately the 12 o'clock position almost dead top.



In general, you don't usually worry about them, although the one pic with the longer "cut" in it is kinda weird.
The seal has no where to go, so as long as the tear doesn't grow, the seal should stay intact.





You talking about that "smear" toward the center of the iron?
Does it pass the fingernail test?
Can you tell it's a depression by running your fingertip over it?

I'll have to rewatch the dvd, but I believe Atkins dvd suggest putting them at 12 o'clock.

About the damage on the front iron. I've reposted the pic. The circled area you can catch your fingernail on. It's been almost a week since I've touched the front iron....but as I remember it you can feel a depression but can only catch your nail in the circled area. I'll reconfirm that later today.

These dents are typical when using some kinda supplemental sealant with the water jacket o-ring?
Petroleum jelly?
Hylomar?

I used hylomar

I guess the 12 o'clock position is technically not wrong, according to the FSM...

I prefer to put the splice where the intake ports are located.
This is the coolest area in the housing.

Sorry for the bad pics, but these are pics from the 1987 and 1991 FSM's...

I don't think that area is an area where the oil control seals actually run over, but maybe someone else can confirm?

Also, do you have your oil control labeled so you know which one goes where?
This might help, but can you mic out the height of the oil control metal rings?
If that area is affecting the oil control ring, it could be abrasive enough to cause the oil control ring to wear prematurely.
