If your timing gears or chain broke it'll do the same thing.
The only camshafts I hav seen break is in the dual overhead cams set up and it was the chain that caused that too.
Also push rods bend and could cause this but unlikly unless the vavle lash wasnt set up correct when the head gaskets were installed.
Looks like you might hav to remove the passenger side of the motor and investigate whats going on, if its the chain/gear or the camshaft is broke.
Its easier to go in this way, instead on removing the intake.

Actually I had 2 cams break in mine. It turned out to be the fuel pump wasn't putting out enough pressure so there was some sort of kickback happening. I am not a mechanic so I can't tell you exactly what the problem was, but I know that it was the fuel pump causing the cams to break.

hey xero thanx for the info. but i have a question. You said that if the timing chain or gears broke it would cause these rocker arms not to work. I've always known that when a timing chain breaks there's nothing to turn the camshaft so nothing should be moving, right? Why would it only actuate the valves on the cylinders 1 & 2 but not the other 4?

Liike I had said before, wheather its a camshaft or the gears and chain , the only real way to KNOW whats going on is to take it apart.
The gears could be partially broken(missing teeth), but it could just be the lifters or pushrods bent, not allowing all the valve train to work.

My daughter had a boyfriend with a 93 GA 2.3L engine. He had the engine apart and couldn't figure out why the car would only go up to 20 MPH and no faster. When I looked in, I saw the camshaft was broken in half. Don't know what caused it or if they ever fixed it, my daughter broke up with him soon after. Good choice right?

Everyone thought my cam was broken on 2.3l 93 grand am but long story short turned out to be coil housing. Replaced and car ran fine again...never would have figured by symptoms car had. Just a thought

my son has a 94 berreta with a 3.1 vin code m his camshaft broke. i did a compression test cyl 1-4 have compression cyl 5and6 no comp at all. we pulled the engine took it apart and cam broke and the exhaust valves were bent when the pistons hit them. the 2.8 3.1 3.4 are all the same engine the blocks were bored out. the best repair is a rebuilt engine

i have never seen it but it makes sense. if your belt broke cam would not turn. if belt slipped cam and rockers would move but just at the wrong time. does sound like broken cam.
