Can used side and corner seals be installed on a different rotor or different location on the same rotor than the one they came out of? If they are in spec of course. I know technically you're supposed to keep them matched up but that ship has sailed as I have these parts from a spare motor I took apart a few years back. Problem is I just threw them all in zip lock bags without marking them as at the time I thought "oh I won't need them I'll buy new ones at rebuild time". Well my motor is locked up and rebuild time didn't come at the best financial time. Also I built the motor in this one. It was my first build and iirc I clearanced the side seals on the loose side so the used ones I have have tighter clearance if I can use them. Thanks.

 

I take it this is an NA build? As long as the used seals are in good shape and clearance as per Mazda specs, you'll be fine. How many miles are on them?

 

Sorry forgot to put the generation. Yes '89 current build will be n/a. 104K on the spare seals. I may not have a complete set as that motor ate the front rotor. My current engine has 147k and I suspect may loose one rotor (hopefully the front as the rear was replaced with a new one when rebuilt) as it's locked up tight. Front rotor has 269k so the apex seal grooves may be out of spec anyway.

I am trying to save enough to get turbo rotor housings as I want to do a streetport on this one and I think my spare housings have a groove from the triangle piece of the apex seal.
