i dont no about a slack chain but what it sounds like is your flix plate on your trans if its a stick for get about it now i no it sounds wird but this happend to me what i did was with the motor runing in park i under my truck with the water hose and spayed the flex plate the sound went away let it come back same thing went away took it apart it had a crack all the way around where the bolts hold it to the crank a good bud of mine his dad worked at clipengers he told me this
check timing. timing advance. or slack in timing chain/belt
No
Possible cam chain tensioner has broke.these tensioners are none adjustable and sometimes brake causing a knocking sound in the motor
The 2 most likely: A. Timing is off. B. Oil is low.
You can tell a timing chain is bad when your engine makes a sharp washboard-like sound that increases in intensity when the engine's RPMs increase.
I doubt it. How do you know the roar is from the throttle body when at highway speeds? Is the knocking a heavy metalic knock or more of a marbles in a tin can sound? Is the snorkel tight at all points going into the throttle body?
A marble sound under load indicates the engine is out of time. Have the ignition timing checked and the timing chain/belt for damage or excessive play.
Nothing... It won't run. The chain will become noisy and the engine may be out of time and perform poorly.
A knocking sound in your Chrysler 300M engine while driving could indicate several issues, including worn engine bearings, a faulty timing chain, or problems with the valves. It's important to check the oil level and quality, as low or dirty oil can cause engine noise. If the problem persists, it's advisable to have a professional mechanic diagnose the issue to prevent further damage. Ignoring the knocking could lead to more serious engine problems down the line.
A hole in the muffler would cause a knocking sound in your muffler. A loose exhaust pipe can also cause a knocking noise.
No it has a timing chain. The tenionsers do need attention if you hear a rattling sound from the front of the motor.
Yes. The A has a short A sound as in stammer or slack.
