Everything still has yet to go through the parts washer and checked for spec but aside from that if all looks good then I'm just in for a new set of rotor bearings.
Bought this engine for $25 in March of '11 so if its crap no loss and if its gold then sweet.

center and rear irons are toast, i see burn marks, which means the rotor might be bad too.

rotor housings look great though, and that is the hard part

Yeah from what I could tell the engine spun a bearing on the rear rotor. I believe the rotor itself is fine but they're both caked at the moment so I figured I'd save judgement on that till they were washed. Apex and side seals all look mint though.

Set your camera to "macro" focus mode and re-take all the pictures.

So are those good enough to verify scorch/burn marks or do I need to retake again? Don't know why I dropped in the apex seals though.

I agree with what j9 posted about the rotor housings looking good and the irons looking like trash.

Apex and side seals looking 'mint' doesnt mean much. How many miles are on them? I'd be willing to bet most of not all are out of clearance.

Definitely have new main (stationary gear) bearings installed along with the rotor bearings.

As posted above, I agree the housing look plenty useable. Those irons are trashed. You wont know on the rotors until you measure. I have had beautiful looking rotors with trashed apex seal slots, and rusty, crappy looking rotors that specced out just fine.

keep the phone for talking and texting and buy a camera for taking pix. that way u chose a setting so the pix aren't so big u have to scroll the page left to right to see the whole thing and u can see if it's clear enough before posting. now with that said, i agree with the others. rotor housings look good enough to reuse but u'll need to find another set of irons. and replace all the metal seals and springs with new. u plan on doing any port work?

after taking a second look, does that one rotor housing have a groove wore into it at the outer edge?

I believe it is, if it matters any it appears to go all around the housing with no deviating lines. Just one solid loop.

As for port work I was thinking about going either street or bridge but was starting to settle at street the more I thought about it. also had i made the pictures smaller, would you have seen the groove?

in that case ur left with only one good rotor housing. and yes, with smaller pix i probably still would have seen it. the outer edge is the first place i look cause it,s where all the chrome starts flaking.

So this randomly started bothering me again this morning. Went to double check and it isn't a groove, but it is uneven wear.

Personally, I'd never reuse a rotor that spun a bearing. Nothing sucks more than tearing a fresh rebuild apart again for a spun bearing. If the bearing spun, you're likely going to need a new E-Shaft, so you'll have to balance the assembly anyways, why chance it. Especially with those nice housings.
