It's before the exhaust, not after it. They normally go at the top and bottom. This is fairly normal wear tbh.
Excess heat is what's flattening out the springs. I bet the corner seal springs were fubar too.
You'll see flat springs very quickly when engines overheat. Poor lubrication is usual culprit over time.

Lol x2 - not sure if its more correct to "loll" or "lol lol" though but anyways.
Yep it only rotates 1 way but I don't get what you are saying?
One chamber is pushing its exhaust out, and just behind it is the other chamber still expanding - therefore it's both before and after the exhaust because the Apex seal is shared between the chambers. Not sure if that makes me right or wrong in the gas pressure reduction chattering thing but any which way you look at it - the housing is fubar and springs are toast
I think it's "lulz" isn't it? In a propah intarnetz stylee. Bruv.
I meant, Ramon, isn't the rotor always going to be sweeping up to the bottom edge of the exhaust port from the bottom right as that picture stands? So the wear is before each chamber actually exhausts its combustion gasses. Or am I just being conspicuous by my stupidity again?

I see your point. Not sure why they tend to go at the top and bottom, but either way its koozed.
You got spares?
is it safe to come out yet? if your asking me if I have spares then yes I do. Just ordered a master seal kit from Atkins rotary and my apex seals have arrived from Australia. Also had my plates lapped and there silky smooth.
