Are my housings scrap?
 

Hi everyone

Just looking for a few second opinions on these housings. I foolishly didn't do a compression test on the engine before I took it to bits.

I know the limit is around 2mm but most of the damage I've seen seems to be prolonged sections rather than little spikes like these are. One of them next to the exhaust port is 9mm though...

Thoughts? Should I scrap them and get new ones or are they okay for a first build?

Cheers in advance :)

Not a builder, but new/better housings are needed. You may need some other parts as well. Pretty deep grooves and flaking. And I'm not certain what was going on that would cause the seals to make chatter marks like that. The seal grooves on the rotors are out worn out of spec is a guess...maybe a builder will chime it.

Like Kanye West's Singing..they are Crap.

they look like some really deep grooves ,I wouldn't use them

Those are scrap, You'd most likely have issues with breaking apex seals if you reused them.
