Valve seats (components in the cylinder head that help seal the valve) can fall out. When this happens, it causes rough running and creates noise. Replacement of the cylinder head is commonly required to fix this problem.

Happened to me #2 and #4 drove it home with a top speed of 25mph. Pulled head as soon as it was cool top of pistons were a little beat but no wall scaring or burnt rings. Replaced valve stem seals and valves on 2 and4 and haven't had a problem since

run rough restarted it couple times it was good. Happen couple times then last time started it was ALOT worse. Shut car off timing belt and timing were good. Thought timing might have jump or something. No compression on cyl 4 removed head. Found that the seat for cyl 4 intake was broken half of the seat still loose and haning on head. The other half beat top of piston. Fortunately no scoring of cylinder wall. Will replace piston rings and head.

Picked up a 94, idled kinda rough so checked plugs, wires, etc and all seemed good, noticed plug on #4 cylinder didn't appear to have any residue on it, like it wasn't firing. Did a compression test and #4 showed 0..all others were good, so now waiting to pull the head and check for the dreaded valve issue or piston.

The idle got rougher, started missing and then lot cylinder 2. I had it tested and they said the valve couldn't seat properly. I haven't fixed it yet.
