Destruction.

Alright so I picked up a 91 318i in perfect condition, except the motor wasn't running, for $400 bucks!
Owner said it died one day in the parking lot and has zero compression in 1 and 2.

So I finally got around to doing a compression check today and confirmed ZERO compression on 1 and 2, while 3 and 4 were perfect.
Head gasket was in perfect condition, and oil didn't have a drop of coolant in it.

Pulled the valve cover, and this is what I find. Seems maybe an exhaust valve or two were open

That's one I haven't seen in an M42, congratulations! Welcome to r3v as well.

Now, get a new/used set of cams/trays/bearing caps after you verify that there are no bent valves or other misc damage to the engine.

Wow- yeah, that's usually a 6 cylinder thing.
