Hello everyone! I recently purchased an older Yale/Eaton with a Mazda UA engine. It hasn't been started in a few years. I finally got it to crank but the engine cranked as if it didn't have compression on a cylinder. I pulled the plugs and cranked it over with my finger over each spark plug hole and the #1 cylinder had 0. The rest had compression. After removing the valve cover I saw 1 bent pushrod #1 cylinder, and 2 pushrods that had the tips laying beside them #2 & 3 cylinder. The # 4 pushrod top was flattened on top and looked like it had been for a while. I found all 4 pushrod ball ends laying in the head. The # 1 cylinder pushrod was the only one not opening and closing the intake valve-hence no compression. These are all intake pushrods by the way. The # 1 cylinder pushrod was also broke which allowed it to move to the side of the adjuster. Has anyone seen this before and if so what caused this to happen? Possible oil pump? Just bad pushrods? Maybe an ether start attempt. All help is much appreciated!
