That's right, I figure if I'm gonna learn I might as well practice on my own motor. Rear rotor is good but the front is shot.













ok here are some pics.

Here is a pic of that evil bastard known as the front bolt.

this is the rear housing looking to be in pretty good shape

the rear rotor is in good shape but I noticed the outer oil control ring was bad so the whole side and 3 faces of the rotor had pretty good oil residue on them

this is the only mark on the rear housing, you can see it but you can't feel it. No worries as I intend to replace it anyway.

Now here is where the problem starts. 1 apex seal was broke and 2 were pushed in. I assume this is what people mean when the talk about a stuck apex seal.

here'a a shitty pic

this is the rotor housing and front plate, the housing is fucked but the plate isn't as bad.

I'll post better pics of the good and bad rotors later.

I hate to tell you but those plates look pretty worn. The side seal grooves look bad in the pics. If you can feel them with your fingernail then they are no good.

Yeah I know it, I'm waiting on a gauge to be sure but I think there shot. It's actually the corner seal groove that's the worst.

Well I measured them and they were all within spec but the side seal measurement was very close to it's limit. I just said &*^% it and sent them to racing beat to get lapped and a large street port, I'l just port the new rotor housings myself with the large pineapple template I have.
