Remember my FIL's Camaro with the funny engine noise? Sure you do.
After we reinstalled the engine it didn't run like it should. We were both frustrated so he took it over to a friend's repair shop. They determined that the crank was bad. They had a machine shop install a crank kit, etc. and then re reinstalled the engine.
On their test drive they blew a rod out of the oil pan!

I swear this car is cursed.
I told my FIL that once he gets it back to get rid of it.
