<p> I believe the lock nut backed off they should have another jam nut to on top of the locking nut. If you use the the locking nut several times they don't hold as well. But I still want to check the lifter for breakage, also could be a week pushrod since it broke into. I will keep investigating .But it's not really important because I am going thru the complete engine an will be checking everything as I go. Feel free to contact me anytime.</p>

<p>Larry,</p>
<p></p>
<p>Thanks a lot for the reply. I am looking at buying a cruzer that has a corvair engine so I am trying my best to learn as much about the engines as possible. Any thoughts on the cause of the failure? Poss push rods not the correct length or adjusted correctly or possibly installed upside down. I read folks had some differences of opinion on the orientation of the rods.....etc....</p>

<p>Charlie, My name is Larry Tramel and I purchased the engine you are asking about. So far I disassembled the engine completely. The only thing I found was some minor damage from the pieces of broken pushrod. I'm reassembling it as we speak.I did replace all the lifters and will e checking the pushrod geometry to make sure it's correct. if you want any more information later own let me know.</p>

<p><em>The longer tanged end should be mounted in the hydraulic valve assembly (into the engine block) so you might want to check that too.</em></p>

Referencing Figure 33, on page 6-22 of the 1965 Corvair Shop manual, the long tang belongs on the head side. This is further confirmed by Figure 19, on page 6-12.

<p>Ha! I disagree. If it were best to leave these issues to the experts, I wouldn't have built an airplane. :-)</p>

<p>Thanks, John. But, it wasn't the rocker arms that I was having trouble finding. I've ordered the roller rockers as replacement. I was having trouble with the valve rotators. It doesn't look like ANYONE carries them as a standard part.</p>

(page 19 has non standard lifter rod lengths but it is unlikely you will need them) Check the length of your lifter rod by pulling out the intake valve rod (same size as exhaust lifter rod). When you put it back in be sure its centered in the hydraulic lifter resting on the camshaft, you will know this when the rod is shortest coming out of the lifter tube. Be sure that the oil hole is up in the rocker arm.</p>
