I have a broken pushrod at the intake valve of cylinder #5. It's the mushroom part at the top. It split lengthwise and half of it was lying in the bottom of the rocker arm space. The rod isn't obviously bent, though I understand you'd have to take it out to know for sure. I was thinking if it was bent it might indicate a stuck valve. Otherwise could just be metal fatigue but I'm just guessing. I checked all clearances and every valve has some clearance when it's closed though a couple are very tight, and that's when they're cold. So I'm thinking take the head off and get it to a machine shop? Replace the pushrod myself and check for free movement of all the valves? Would appreciate any suggestions. Thanks.
