Sorry about your troubles. When my motor let go, I considered it a blessing. Forged is more fun!!

not sure what kind of damage...car seems to run...ok....even pull pretty decent....dont really want to start it.....maybe going to rent one of those camera scopes and check it out and see if the piston is broken....what kind of damage would cause a 30 reading on a compression test...broken ring or broken piston

Pull the head and check it out.
Camera scope's not a bad idea though.
Mine blew the #7 (tuner was doing a dyno pull) and broke off the top of the piston and exposed the ring (about 3 yrs ago.) She was puffin' out the breather cap.
Did you see any white smoke from the tail pipe?

multiple reasons.
- hole in a piston
- melted/broken ringland
- broken ring
- cracked liner
- broken/bent valve
- blown head gasket

I feel your pain man. I had smoke from the tail and breather. Did a leak down and had over 35% on 1 & 3. Havnt got mine out yet but that was enough for me to pull it apart. Hope you get it fixed up soon.

no smoke from exhaust..no white smoke.....oil looks fine ...car even pulled ok...i knew something was up so i didnt push...pretty sure its not a valve....i used the stephescope to listen and really didnt hear anything out of the ordinary....not ready to take it apart because one way or another the car is still mobile....going to camera it...
