Several have replaced the push rod tube seals with the engine in the car. I don't think you can totally remove the tubes, but you can pull it out enough to replace the seals.
I personally would pull the engine, I don't enjoy working in tight spaces like that.
I find it easier to replace the push rod tube seals in the car.
So long as you dont have a 75/76 with stock HE's...those suck.
Pull of the valve cover
Pull of the rocker assembly
Pull push rod spring
Leave push rods in car (cant get them all out anyways)
Pull push rod tubes...they wont come all the way out.
replace seals
re-assemble.
If you pull the motor, then you need to get it up in the air hihg enough to pull the pushrod tubs out.
