I've seen many forums where it has happened to people 3 and 4 times on various model cars. I guess the seals have to be perfect. It just sucks redoing everything and not being sure what the issue is.

The worst I've had happen with the spring loaded cams was scratched up hands. I've had them "spring" on many models of cars without issue. It's not strong enough to do damage.

Crank seal replacement was fine and doesn't leak, but it had a seal lip pretty close to the edge. These cams have oil drain passages so I suspect I just have one of them pushed too far back.

Make sure to replace the crank bolt with the newer revised version. https://www.amazon.com/dp/B005HAP1VQ/ref=cm_cr_ryp_prd_ttl_sol_0

Also make sure you double check the part numbers of the seals you remove or use the Mitsubishi ASA so you don't run into what I did with having the wrong parts. Don't let my crappy experience discourage you either.
