Hi. I have a 2001 dodge 2500 with a cummings diesel. Ever since I've had it is knocks really bad. Does anyone know why? What can I do to stop it?

I forgot to mention Ive been boosting 18psi on stock motor. I posted this here because its turbo and alot of people here know a lot about turbo stuff.

TIA

Crank the boost to 60 psi then you'll be alright!! If not, just swap a B18 in it!!

 

check the muffler bearing. that might make the knocking go away!!

 

Ether, ether, lots of ether will make that dreaded knock go away...

 

lol, someone must be really bored. BTW I don't think a diesel is supposed to make that knocking noise, its supposed to be as quiet as a gasoline engine.

ban this n00b!

 

Your knock sensor needs to be replaced.

 

You may also want to try higher octane fuel.

 

lol so true

Yeah that or need to change the spark plugs.

 

I hope you are using premium gas. Maybe you should try racegas?

Colder plugs would help too.

Captian obvious has arrived..

 

not enough propane!

 

your hearing detonation

 

you might not think this will help but it helped my uncle billy. he was low on blinker fluid and accadently poured the fluid for the blinkers in where the spark plugs go on a deisel. dont ask me why he did that, but that made it knowck real loud, and also ever since he had it he has to turn on the key and wait a few seconds before he cranks it, huh must be a lemon.

My friend who is into diesels said it may need a valve adjustment, he said to check
out http://www.tdr1.com for diesel info. Hope that helps.
