Hey! I have a 2002 Camaro V-6 it only has 50,000 miles on it. I drove it today, and it seemed to be fine...then tonight I went somewhere, drove about 5 miles, stopped to get gas...and after that it started getting hot?....well....we ended up putting water and also oil in the car. Then I drove it about 10 miles and it was fine and didn't get hot at all, I stopped for an errand...came outside and it got hot again...I stopped had a friend come look at it...and it didn't get hot anymore...Well I was going up a hill to come home...and it actted like it was going to die....when i start the car up...it knocks for a few minutes...and then the knocking drowns out...any ideas of what this could be? Thanks you guys!

Was it a knock or a ping? I think your talking about a ping. When these cars get hot like your describing the computer is doing everything in its power to maintain a proper fuel balance in the engine. The heat of the engine is causing a detonation in the chamber before the spark ignites the fuel. This causes a ping in the motor which trips a sensor and tells the computer to richen up the fuel mixture. At the exhaust end you have the OS sensor telling the computer to lean the mixture out because there is too much fuel. So the sensors start playing hell with the computer. Eventually something has to give and you get the pinging sound that you heard. Now not having water or oil in it is a contributing factor and it is likely you have done damage to the motor. If it were wrist pin or bearing the sound might get a little better as lubrication improves but you would still hear it. Take it to the shop and have it checked out. Have them look it all over and see what is causing the over heating issue and also have them listen to the motor and see if there is a knock. However I am betting that the sound you where hearing was a ping in the engine instead of a knock. In which case you lucked out. From now on I would recommended checking the water in the morning before you go anywhere and the oil every fill up.

yeah I agree, its most likely a ping from shitty fuel that you just bought from a gas station that is selling old or watered down fuel, in order to make a profit, You probably haven't burned enough fuel to add a full tank of higher octane fuel from a different gas station, so i would recommend, adding two bottles of the cheapest octane booster, and I like the walmart brand, but you can pay the extra ten bucks to buy the good stuff if you like. add it to your tank. i bottle will raise your octane 2 pnts, and treats 15 gals, once both bottles are added, you will need to mix the gas in the tank, drive it around, or put gas cap on, get on the bumper and jump up and down for a little bit, because normally you anytime you put a additive in the gas, you do it before you fill up because then the fuel flowing in mixes the additive. you should see results in about 10-20 miles. hey its the cheapest troubleshooting step, and it wont harm anything, as a long as you keep an eye on your gauges.

if its knocking you either have a bad bearing or a bad wristpin? it doesnt get any better my friend. the motor will need a rebuild. change the motor oil and leave it a quart down and add a quart of lucas. it may also be your valves you hear. its more of a chatter then a knock? do you see any metallic shaving in the oil? email me back? usally a bad bearing doesnt make the car seem like its going to die. the knocking you hear is because the bearing are worn thin and its allowing the crank to move and i guess slap the journals.
