Did you use a tork wrench to tighten them? Check for vacuum leaks also

SOURCE: 2002 Pontiac Grand Prix Thermostat

as you face the engine the thermostat bell is on the right (drivers side) Follow the radiatoe hose. Remove the two bolts and raise the bell still attatched to the hose. the thermostat is there with the rubber seal. You can gently pry the thermostat out with a screwdriver or something similar. Put in new thermostat be sure it is the same as the old one, and then replace or change the seal (be sure it is the smae size and thickness as the old one as I got the wrong size from Napa) Then replace the bell, and tighten, but not over tighten. I hope this helps!

SOURCE: 2002 grand am 4 cylinder rough idle and rough running

Check the ignition control module. Sounds like the exact same problem I have had with mine. Took it to the dealership and the were able to tell me right away. The ignition control module is very easy to replace and is located on the top of the valve cover. Hope this helps!

3400 v6 rods and lifters


Unless something was very worn, my first thought is the lifters had lost all oil pressure. The lifters are hydraulic and should maintain pressure to keep the rockers tight.

Adjust lifters


The push rods on the 3.1 engine are different lengths, so they may have mixed them up. The rocker arms are torqued to 85-90 INCH pounds, not foot pounds. You have to use an inch pound torque wrench.

My 2002 Grand Prix burst into flames, no apparent reason. Any advice or recourse?


take a look at this hope it helps. engine recalled about fires:

Recall Reason ENGINE AND ENGINE COOLING Recall Date MAR 12, 2008 Model Affected GRAND PRIX Potential Units Affected 207542
Recall Summary GM IS RECALLING 207,542 MY 1997-2003 BUICK REGAL AND PONTIAC GRAND PRIX VEHICLES EQUIPPED WITH A 3.8L SUPERCHARGED V-6 ENGINE. THESE VEHICLES HAVE HIGHER FRONT ROCKER COVER GASKET TEMPERATURES, CREATING THE POTENTIAL FOR EARLIER DEGRADATION OF THE FRONT ROCKER COVER GASKET AND EVENTUAL OIL SEEPAGE.

Consequence CERTAIN UNDERHOOD FIRES MAY BE CAUSED BY DROPS OF ENGINE OIL, FROM SEEPAGE OR SPILLAGE, BEING DEPOSITED ON THE EXHAUST MANIFOLD THROUGH HARD BRAKING. IF THE MANIFOLD IS HOT ENOUGH AND THE OIL RUNS BELOW THE HEAT SHIELD, IT MAY IGNITE INTO A SMALL FLAME AND, IN SOME INSTANCES, THE FIRE MAY SPREAD TO THE PLASTIC SPARK PLUG WIRE CHANNEL AND BEYOND.

Remedy DEALERS WILL INSTALL A NEW FRONT (LEFT) ROCKER COVER GASKET WITH AN IMPROVED DESIGN FROM THE ORIGINAL GASKET AND REPLACE THE SPARK PLUG WIRE CHANNEL WITH NEW RETAINERS. DUE TO PARTS AVAILABILITY, OWNER NOTIFICATION LETTERS WILL BE MAILED IN TWO PHASES. THE CUSTOMER LETTERS FOR THE 1997-2000 MODEL YEAR VEHICLES WILL BE MAILED ON APRIL 28, 2008. GM WILL ADVISE AS TO WHEN THE OWNER LETTERS FOR THE 2001-2003 MODEL YEAR VEHICLES WILL BE MAILED. UNTIL SUFFICIENT PARTS BECOME AVAILABLE, GM STRONGLY RECOMMENDS THAT OWNERS OBSERVE THE FOLLOWING IMPORTANT PRECAUTIONS (1) THEY STRONGLY RECOMMEND THAT OWNERS DO NOT PARK THEIR VEHICLE IN A GARAGE, CAR PORT, OR OTHER STRUCTURE; (2) IF OWNERS NOTICE A BURNING ODOR, THEY SHOULD HAVE THEIR DEALER INSPECT THE VEHICLE. THE DEALER WILL INSPECT THE VEHICLE WITHOUT CHARGE; (3) USE PREMIUM FUEL (91 OCTANE OR HIGHER) IN THE VEHICLE AS RECOMMENDED IN THE VEHICLE'S OWNER MANUAL. OWNERS MAY CONTACT BUICK AT 1-866-608-8080 OR PONTIAC AT 1-800-620-7668, OR THROUGH THEIR WEBSITE AT HTTP://WWW.GMOWNERCENTER.COM .

Changed intakemanifold gaskets for 3100 sfi motor now theres a lound knocking comeing from motor


On the 3.1L engine you have to remove the push rods to replace the intake manifold gasket. It is possible that you didn't tighten down one rocker arm, or you have it mis-aligned.

Grand prix has a 3.1 6cyl. and 166000 mile, it blow white smoke


Sorry to inform you of the bad news but the white smoke is engine coolant burning off and the rough running condition is also associated with coolant leaking into the combustion chambers.This will be a head gasket repair, basically a head job where you will need to machine the heads down and install new gaskets from the heads up.Get back to me if you have any more questions, thanks and I hope I could help!!!
