I've now run across 4 burned exhaust valves in EJ22's

Konrad/soo's 1995 EJ22

My 1992 EJ22 twice Here's one of them:

Customer at a local shop's 92 EJ22

 

I did a search and turned up:

94 EJ22

All the valve's ive seen have big pie-slice chunks missing out of them, with slag tails going off the back, just like someone took a cutting torch to the valve.

I think I'd argue that the Achilles' heel in the EJ22 is the lean-ness of cylinder #4.

Well, I wonder if the burnt valves have been primarily on #4. That would explain a lot.

Were they maybe not closing all the way or something stuck on the seats or something?
