valve clatter
From : edtheward
Q: 2000 dodge ram 4x4 360 55k miles i have been hearing valve clacking lately under acceleration and it does not need be hard acceleration to hear it. i can hear it better now that it has warmed up and i have the window down. people talk about pinging is this the same thing it doesnt sound like a ping to me more like clacking or rattle. it is not really loud but i am wondering what was causing it. i have done some searching and the plenum gasket came up. i was told to look down the intake with a flashlight and it you see oil at the bottom the plenum gasket needs replaced. well i looked and it looks dry to me. i am not burning oil and i do not get a puff of smoke when starting. i have run 4 bottles of injector cleaner/carb cleaner/whatever through it and it did not seem to help. any more suggestions of things i could check .

something to try...if youre using regular unleaded. before you gas up again run the tank to empty...then run some premium and see if it still makes the same sound. ill venture to say that right now you are running regular...and also that when you run the premium the noise will still be there...but nowhere near as much. if this is what happens then youll need that plenum kit. its a simple way to check. -- ------------------------------------------ laszlo almasi ----cool toys formerly carolina watercraft works ----mack daddy trailers ----ice angels what grade of fuel are you using -- ------------------------------------------ laszlo almasi ----cool toys formerly carolina watercraft works ----mack daddy trailers ----ice angels actually this is what you need http//www.hughesengines.com/partdetail.asppartid=11698 -- thanks i know about the kit but i am not sure if that is the issue. .

off corse you do not hear it ping because your ecm it controlling it before you hear it duh... you do realize that a 318/360 has no ability to retard spark based on knock/pinging right .

anyone know exactly what years the plenum gasket is an issue seems to me it effects model years up through 2000. i only know of one person who has ever said they had problems with a 2001. i have a 2001 with 76000 miles on it and so far no problems. it was pinging bad the other day while under load up a hill but i think i just got a bad tank of gas. have to keep an eye on oil consumption. carolina watercraft works wrote actually this is what you need http//www.hughesengines.com/partdetail.asppartid=11698 .

i do believe that i clearly stated that it didnt ping. if it did then you would be a fool to continue to operate it that way and i assumed that most in here would know that but if it doesnt and the manual states to use 87 using higher will simply waste money. i agree that it is a waste of money using a higher octane fuel than required. the owners manual recommendation isnt going to be right all of the time. as an engine gets older it forms carbon deposits on the pistons. these deposits create hot-spots that can cause pre-ignition ping when using low octane gas. you can tear the engine down to clean off the carbon deposits and continue to run 87 octane gas or simply switch to the mid-grade or premium to stop the pinging. -- ken .
