360 engine vibration
Feedback from tonight.
I didn't do compression test again. I wanted to try something I haven't revisited 5 times LOL. Although I might just do it again before I put plugs back in.
Removed the rocker covers and noted all the rockers in about the same position see photo below. Now thinking about this maybe I'm used to a 4 cylinders where the pistons are 90deg out and a big difference in pushrod position from 1 cylinder to another. As a cranked it on the battery all moved up and down about the same amount, I took a video and will post later. So nothing too much a miss here however I do appreciate this is cranking speed and not 1000rpm. So still have planned the seafoam and oil change when it arrives.
On to the front damper wobble. The damper part moves in and out from timing mark approx 1 to 2 mm ( wobble) seems the inner part is doing the same, video this too. Bent crank !!!!!! So took out the rad and stripped front pulleys and damper off crank. Turned engine over on battery with DTI on crank only a minor variation 1 or 2 thou if that, could have been the DTI moving too. So happy crank not bent, phew!
Im going to take the balancer to work and run up in a lathe, maybe it got bent when someone pulled it off? But would this wobble account for vibration lumpiness? photos of damper below, is this the correct 360LA one? Has the number 85985 0259 stamped on it.
