All you rebuilders, how often do you find usable housings and rotors when you buy a core 13B NA engine from a junk yard?

I cracked open my can of worms tonight (oops I mean my engine) and both housings and one rotor are bad. One rotor / housing is from me dropping something in the exhaust port while installing my header . . . the other housing is scuffed pretty deep right before the top spark plug from excessive carbon buildup on the rotor.

How many cores do you think I will have to buy to get a rotor and two usable housings?

you might be able to save the rotor by machining it for 3mm apex seals. the seals are expensive,but it might be cheaper than buying a good used rotor.
you might want to try and find good used rotor housings from a rotary engine shop.
I wouldnt try buying engines out of the junk yard.

Actually the one rotor died because I dropped a nut from my 5th/6th port actuator onto the exhaust manifold when I was changing in my header. It eventually slid off into the exhaust port as I was taking the manifold off. When I started the engine after installing my header, the nut got ground between the rotor and housing and now my rotor is dented and chipped in a few places, not just the tips. The housing is scraped worse than when a seal ejects because of detonation under boost . . . It is fooked up real good.

Betcha won't do that again...lol
