Rotor housings... are they paper weights...
these fd housings have seen better days just received these from a local guy after some cleaning i found these lovely cracks... yippy whats everyones thoughts?
Definitely not ideal. Looks like they have sanding scratches from a do-it-yourself resurfacing attempt and significant cracking. Under boost/heat the cracks can lift causing contact with the apex seals. You can take down the cracks by porting with a sanding drum directly over them to give more clearance, but I wouldn't recommend using those for anything turbo that you want to last.
