Dipstick Problem after Rebuild for 1967

Q: Dipstick Problem after Rebuild for 1967

I just rebuilt a 326 Pontiac motor to put onto a 1967 firebird. Before I had it rebuilt the dipstick was fine like it should be. But when I got the finally put in the car and fired it up the dipstick shoot right out of the the motor. I got out of the car with it still running and started to put it back in the motor but it keeps hitting on the cam. CLICK CLICK CLICK I even order a new tube and dipstick together and put it in. I still have the same problem. I was wondering if you knew what could be the mess up? Thanks

A: I posted a similar problem on one of the performance years pontiac boards. When you replaced the tube, do you mean the external tube, accessable from the outside of the engine? Sounds to me like your inner tube is bad. You have to pull the oil pan to replace it. To do this you may have to pull the engine or if you’re lucky you can just remove the distributor and jack up the engine to get it off. The lower tube inserts into the block from below. That’s as much as I know since I haven’t actually done this yet, I still have the click click problem unless I put in the dipstick just right.

A: Your dipstick is hitting the crankshaft and sorry to say I think that the lower portion is bent or missing. You may have to PULL the oil pan to see what is going on down there. You didnt mention if the car has A/C or not. A/C cars use a different dipstick and dipstick tube perhaps you have a short tube and a long dipstick. You can check this by putting the car on level ground and check the oil level on the dip stick. With 5 qts. in the pan you should read about 1/2 qt low on stick.
