Here is a stresser.....my '73 2.0 lost power and during diagnosis found out rocker arm shaft had come loose and fallen out. No damage to anything except a groove worn into the pushrod two inches in from the valve cover side. I found the two nuts but only one wavy washer. Car runs with no noises or any odd sounds but I hate to button it up without finding the missing washer. Changed oil and nothing on super magnet plug. Any ideas where it might be?? Thank you!!

Yes, the wires can absolutely cause that damage. The pushrod body is aluminum, the wire is steel. One of those things is harder than the other--guess which one wears? We've seen it dozens of times.
The cure is to install the wire properly. The lower parts of the wire should rest on the "shoulders" of the pushrod tube. They should not stick down into the tube. The wire is important, as it keeps the tube from sliding out as the engine grows and shrinks. (As it does with heat.) Unless you're Elyutt, in which case about six tubes of orange RTV is the perfect solution. They didn't really put many extra parts in these engines. (Follow Elyutt's lead if you want the same sort of abuse he gets for that. (IMG:style_emoticons/default/wink.gif) ) --DD |
