Just tore my T2 motor down need opinions pics inside

[don3vor]

So the T2 housing do have wavy surfaces but not entirely across ( *for reference* about half a finger width on either side of the spark plug holes) but in different places some parts are smooth too. I also checked my NA housings and they look good so I'll be using those just gotta swap exhaust sleeves...

I have a question about a deep groove that I found on the irons, all of them have it actually, some deeper that others is this...bad ,normal can it be lapped out?

You can basically ignore like the 1mm edge of the rotor housings...
The triangle assist piece on the apex seal rides in there, and it will always gouge that outside edge.
I try to keep the triangle assist piece of the apex seal on the side with the bad edge - for original motors.
Sometimes you'll see both edges with grooves - this usually means the engine was rebuilt and the rebuilder flipped the rotor housings (front to back, and vice versa), which I tend to frown upon...

There is a limit in the FSM...
It can be lapped out...to a point.
If you lap the side irons too much, you're taking away clearance space in the water jacket o-ring groove.
If you take away too much out of that o-ring groove, it can cause that o-ring seal to squeeze out and cause an engine failure...
So don't go too crazy trying to lap them.
Also, you're going to change the e-shaft end play clearances, so you're probably going to have to swap out the spacer in the front assembly under the front oil cover.

It's probably easier to find another, better shape side iron to replace your bad one...
