Bent push rods, what's the cause?
The 289 engine of my 67 coupe was not running nice at all when I bought it, so I decided to troubleshoot. I knew it needed a new gas tank and a carb rebuild. I did all that and replaced all like sparkplugs etc etc.
Then I took off the valve covers and I saw that 4 rockers were off the pushrods. After further inspection, I saw that 4 pushrods were bent of which 2 seriously. I had to take off the intake manifold to get the 2 worst bent push rods out. See pictures. Tonight I saw the stud rocker arm of several cilinders had a difference in heigt. So I could never get the rockers properly installed on the studs, too much gap between the rocker and the spring. Ho can I get this problem fixed and what could be the cause of the bent pushrods? I don't want to install just new pushroads with the risk that it happens again.
Thx for any advice,
I'm in heaven with my '67.
