Opinion of wear on these seals?
 

i was hoping somebody could give me an idea as to what causes seals to wear like this?

lowish compression on the rear rotor, front rotor was fine, side seals were all good.

only notable thing was a little wear during the pulldown. a bit of a shamfer where it has worn more, towards each end of the seal, lines up with the exhaust port edges.
did not suffer the same problem on the front rotor seals. no seals seem to be warped, were checked on sheet of glass with feelers. 2,000km in the car @ 20psi. although it was like angry pack rape on the motor with the way i drive :lol:

sorry about the pics, i did my best :)

What brand seals are those, and can you post pictures of the exhaust ports?

exhaust port chamfer lip isnt good enough on that rotor

my thoughts as well...
but spot the difference between them... i cant see it, or feel it

nothing has been cleaned yet, just wiped down

option a or b?

A is the problem housing:scratch:

PTS

however this is NOT a seal problem, i want to make that very clear :nod:

A

- see the carbon streak where the apex seal is not following the housing
suspect the lip of that exhaust port is lifting the seal up under heat

spec it out and maybe go nuts on both with chamfer

if you say so...

chamfer looks fine to me, seal warpage under various circumstances would be my guess. you can blame it on the seals warping out in the center or you can blame it on a lean condition which is warping the seals out in the center.

easy fix would just be to add water injection, should help prevent whatever is going on.
