I have a 66 Tbird with a bad set of lifters so I just replace them. I started it up and it ran great. After I replaced the vacuum lines, covers, etc., it started back missing on three cylinders.
Was the cam brokein properly after the rebuild? If not it could have ruined the lobes on the camshaft, and that means a new cam and lifter set.
Did you do this work yourself? amazing- that is a classic sorta, and if you "rebuilt" the engine, it could be anything- how can I know? just start diagnosing why those 3 cylinders are not firing- is it the ignition system? is it the vacuum lines and it just sounds like it's missing? good luck-
Thanks tennissshoes. My dad said that but I was hoping I didn't have to pull the engine out again. Thanks jamnblues. My dad and I are doing the work.
I would check ignition wireing to spark plugs,if its old it may not give spark to plugs when hot.
It was the cam. After I replace the cam, it ran like a dream. Thanks
Bummer you had to pull it again, but now it should last for years to come. Maybe when it is finished you could send us a picture. Thank for using car gurus. Happy Thanksgiving
