The valve pulled out of rocker arm mid 2008 on #2 cal costing approx 600.00 repair again in 2009 the #3 cyl valve pulled out effecting another repair. then a week later the #5 cyl has quit firing. this is the 3400 or 3.4 liter engine. my mechanic explained this was a common problem with this motor in the grand am or grand prix. *tr | |||

Was told intake manifold gasket failed. over a thousand dollar fix with religious oil changes and coolant flushes, should not have happened. i have talked with many montana owners of different years and all have had the same problem. this cannot be a surprise! there is something wrong here... even two different repair shops said this is a common issue of the pontiac montana. i was told they were surprised it didn't happen sooner and there were signs it was in the making for awhile. please look into this! its not a cheap fix! *tr | |||

Tl*the contact owns a 2003 pontiac montana extended cab. the check engine light came on, the vehicle was squealing, shaking, and squeaking. the mechanic stated that it was missing a cylinder and the engine was loose. the rocker bolt fell off of the head of the rocker arm and the head had to be replaced. the failure increased at speeds between 30-45mph. the current mileage on the vehicle was 85,500 and the failure mileage was 85,400. the purchase date was unavailable. | |||

Check engine light came on and vehicle began to run rough. after service work was performed to diagnose the problem it was found out that two bolts that hold the rocker arm assembly on for cylinder #3 were in fact stripped and fell out of the engine head. upon discovering this it was determined that checking the other side of the engine would also be prudent. there we also found one stripped bolt on the head. this engine had never before been apart. we bought the vehicle new and were shocked that such a mechanical failure could happen at 62,000 miles on a three year old vehicle!!! *nm | |||

While driving the vehicles under normal conditions the vehicles turns itself off. while at stop lights the vehicle chugs and the rpm gauge dives down. when starting the vehicle and after the engine is on and the key has been released, the starter continues to crank on its own. *jb | |||

Intake manifold gasket is failing...and gm knows of this widespread problem and refuses to fix it out of warranty. my coolant was leaking out and they would never find the problem under warranty, and now they refuse with 4 months out of the warranty. amazing.*ak |
