Turns out it was so old and dry that it broke into pieces that fell into the valve cover. I don't want that in the oil system, so now I have to take the valve cover off before I can start the engine again or do a compression test.
It's a bit of a pain because of the AC compressor, but I get the cover off and find a crispy black worthless gasket under it, along with this:
The second rocker from the front (right on photo) is loose and sits twisted off the side of the valve spring. I took it off and find the pushrod is bent and there is a really big gouge in the side of the stud where the rocker was cutting into it. The hole in the rocker is also worn out of shape a little. I thought there was a lifter making noise, but I believe this was the problem.
Now the tough decision - keep digging or pull the motor out? I really wish I had done that compression test, and I really wanted to drive it before taking it completely apart.  |
I have had some experience with this on my 73, the stud was messed up and started to come loose. My dad was looking at it with me and told me I had 2 options, either pull the head and take it down to have the stud welded in, or pull the stud, thread the hole, and use a threaded stud. The original studs are pressed into the hole and can be removed using a nut and a socket that fits over the stud, just tighten down the nut and heat the head at the base of the stud with a map gas torch and it will pull out. Then you can find replacement stud kits that come with a tap, you tap the hole, and thread in the new stud with some green loctite and voila... new stud. then you can get a new push rod pretty cheap at the local auto parts house.
