That looks like a lifter cup, like a bent pushrod beat the snot out of the retaining clip and oil pressure popped out the seat.
No compression on '79 318 cylinder 7

This looks like the top of a lifter plunger where the retaining clip popped out.
This ^^^^
Yeah, das a goodun too, but we have our own magnum resource right here on this forum as well. It's not like any of it is magic or hard to do. Not like this guy makes it out, anyway.

Similar bends seem just a bit suspicious to me. Two stuck valves? ummm........maaaaybe.
Wondering if those two push rods were ever in the rocker sockets when installed.
That's an interesting theory and would certainly explain it.

Been there done that. The SNAP it makes when it pops back into the center made me jump like I was shot and once!
Hah! You want to be more intrigued. The engine didn't run bad, just had a little lope to it. And the #3 cylinder with the bent push, it had 130psi on the compression test. Except for #7 which had no compression, everything else was 120. #3 sparkplug had soot and #7 had wet soot or oil. Just weird.
We definitely got the engine like that. Only put 20 miles on it to adjust the kickdown. After I got it on the road it would run good one day and be missing the next. Finally got around to a compression test and that told the story. That's when I asked for help.
And thank you guys for the help

Well of course the cylinders had compression. The intake valves were closed all the time. lol
No 7 had no compression. Which was weird and I asked about it but got no response. The push rod barely touched the intake valve at its apex. Was sure it was a stuck valve and almost pulled the head. Then thought I'd better ask you guys first. Also the oil was filthy after 20 miles.
Too bad it ain't a slant 6. I'd come get it. If it was though, it'd still be runnin. lol
that's a dandy!
Oh yeah illahe that's old post and way too much trouble. I didn't even know a magnum wouldn't transfer parts. We got a rebuilt 360 so the parts will transfer. He's real happy and half the price. It was sweet though thinking about it.
