Tired of DIY!

Sorry for the late response. I went to bed.

The leak must be the rear main.
The cam plug was obviously leaking so I thought that must have been it.
Dripping down the inspection cover on the bellhousing...I did find oil on top of the starter...but I wiped my finger on the heads all over the back corners and came up dry, so I don't think its the valve covers. Sending unit fitting is dry as a bone.

Motor doesn't sound or pull right.

Timing is 20/34.

Carb is whistling intermittently and stops when I move the throttle. Hoping it's not a leak at the shaft. It's hard to tell where the sound is coming from.

Lifter preload was set at 3/4 turn with the intake off. Comp Pro Magnum rockers. Valvetrain is very noisy! More than before.

If I can take the heat and have any energy after work, going to pull some plugs and take the carb back off for a look and new base gasket.

Another thing to note. The gas in the tank has been in it since February, but the carb was drained when pulled.
