Sorry to hear about your pucker situation,but if you want feedback input , it would be helpful to know what engine you are talking about and specifications.
Well, I did post this in the Corvair forum. Would it being a 3100cc vs 2700cc make a difference in a rod getting bent?
You don't seem to have valve rotators in your exhaust valves. Who did your cylinder heads job?
I bought the engine second hand. I can't find any references to Corvairs using rotators.
Almost all Corvair fly engines have exhaust valve rotators. Go to flycorvair.net and search for "rotators", you'll see plenty of references, including the video bellow;
I'll second Dave suggestion to call WW or DW, (does not mean to shut down this conversation). I see another issues in your picture, the top of the push-rods tubes seems to stand out more than normal, compare yours to the video, if that the case, it could be the root of your problem.
Just noticed you are already in contact with DW in CorvAircraft. Just make sure, if you haven't already, that he sees the pictures of your head above.
Congrats on your piloting skills in getting yourself and your passenger safely on the ground. I would highly recommend you give William Wynne a call at 904.806.8143. He's openly invited that Corvair builders call or text him as needed. He'd be most qualified to help you diagnose what happened with the rocker arm and push rod. Otherwise, you might receive some less helpful advice from us arm chair experts who may or may not have Corvair experience.
A forum is a place for "arm chair experts", and I've seen Wynne be wrong about enough stuff to consider him just another "arm chair expert". Please don't try to shut down our conversation if you don't have anything to offer.
Ernest, wasn’t trying to shut down the conversation at all .. merely offering my own arm chair advice as I had built my own Corvair and have been flying it for over 500 hours. Good luck and hope you resolve your engine problem.
Update: I suffered the heat to work on her out on the ramp today. When I pulled the rocker arm, the push rod was in two pieces. I'll try to get a good picture of what I think looks like metal fatigue. I was probably a defective push rod that just took 20hrs to fail.
