how can i stop my enging from pinging?

Question

i have a 2000 dodge ram 5.2 magnum, it has 54K miles and just a few weeks ago the enging started to ping, but only when the engine is under stress.i put injector cleaner which only temp solves the problem. what else can or should i do?

Answer 1

The most likely cause of the pinging is oil getting into the combustion chamber(s). It's very common for this particular engine to have the gasket on the bottom side of the intake manifold to disintegrate, allowing the engine to suck oil from the engines' valley area. Oil has a very low "octane" and causes the pinging. To verify, remove the air cleaner from the throttle body, and look down the throttle body (with the throttle wide open) and see if there is any trace of oil on the intake manifolds' pan floor. If you see any oil, the intake needs to be removed, and the pan gasket on the bottom of the intake manifold replaced. You should then run some combustion chamber cleaner through the engine to help remove any built up carbon. This should fix your problem. FWIW, you CAN NOT adjust the timing on this engine, turning the distributor only changes the time slot for when the fuel injectors inject fuel to each cylinder. You need a scan tool for this adjustment. HTH, Good Luck!!

Answer 2

THE INJECTOR CLEANER HAS A PROPELLANT WHICH CAN INCREASE OCTANE LEVELS THUS ELIMINATING PING
BUYING HIGHER OCTANE FUELS WILL ALSO HELP HERE
I AM GUESSING THAT AFTER 54K THERE IS SOME CARBON BUILD-UP ON THE VALVES AND PISTON HEADS
TRY A GOOD FUEL INJECTION / COMBUSTION CHAMBER CLEANER....NOT ONE YOU POUR IN THE TANK
ONE OF THE THREE PART SYSTEMS TO RUN THROUGH THE ENTIRE SYSTEM...PLENNUM, INJECTERS, ETC
THIS WILL DECARBURIZE THE CYLINDERS, VALVES AND TOPS OF THE PISTONS AS WELL AS THE PLENNUM
CARBON ROBS OCTANE
ANOTHER GOOD PRODUCT IS CALLED SEA FOAM
YOU WARM THE ENGINE AND PULL A LARGE VACUUM HOSE OFF THE PLENNUM. STICK IT INSIDE THE CAN AND WHEN IT SUCKS THE PRODUCT INTO THE ENGINE IT WILL FLOOD IT AND KILL THE ENGINE
LET IT SIT FOR 15 MINUTES
WHEN YOU RESTART IT THERE WILL BE ENOUGH SMOKE TO KILL EVERY MOSQUITO IN THE COUNTY SO DONT DO THIS IN THE GARAGE
THE SMOKEIS FROM ALL THE CARBON BEING RELEASED
DRIVE IT ON THE HIGHWAY A FEW MINUTES AND YOU SHOULD STOP SMOKING
THIS IS ONE OF THE BEST PRODUCTS I HAVE EVER USED
DUMP THE BALANCE OF THE CAN IN THE FUEL TANK AND AWAY YOU GO

Answer 3

Doges are popular for engine noise... I had the same in a dodge van 2500. I tried using a higher octane gas and that did nothing. What did work .however not always was adding injector cleaner and a can of octane boost.along with a better fuel (Sunoco) is the fuel I use. Again I see a lot of dodge vehicles do this... Sorry if this doesn't help you.

Answer 4

You may have to add an octane booster to the gas. Try the premium gas first though. A car with a computer should not ping if all the sensors are working properly. Anyway try the better grade of gas and then the octane booster.

Answer 5

Have the timing checked and make sure you are using the right octane fuel. Oil companies change the fuel formula between winter and summer. Your engine may require a bit higher octane during the colder months.

Answer 6

Run premium fuel or retard timing 3 degrees.They have a dealer cleaner to run thru the injectors for Canada cars runnung leaded gas. It cleans the carbon deposits.

Answer 7

but the higher grade of gas...DUH!!!
the carb/injector cleaner raised the octane rating of the gas you already had in the tank.

Answer 8

Put a higher grade of fuel in your car.

Answer 9

try a higher octane of gas or switch the stations you buy from
