Hearing a very odd noise from an 03 Max. It sounds like knock or a rocker, but dont think its a rocker.

THe noise is present when rpms are decreasing. Its heard while driving but when revving in neutral its very present.

Is this one of the notorious problems with the 3.5 engine? Fortunately there is still warantee on the car bumper to bumper.

here's the vid

definitly sounds like the timing chain is making quite a racket

 

its slightly to the left but sounds a little more toward the rear of the engine.

at the time of the video it was present when rpms were decending, and in neutral with no load.

Sounds like there is sometype of oil starvation but oil level is normal

 

I've done a few waterpumps on 3.0's and they make that exact same sound for the first 30 seconds or so until oil pressure builds up in the tensioners, it's definitly a timing chain issue, it's under warranty, bring it to a dealer, you'll probably get a new motor.

 

in this case the car was already fully warmed and was driving for 20 from the parts store to my house.

I'll run some tests and see what I can find out.

 

is the y pipe i just i had the same problem is the inside of the y pipe the pipe is a 2 in 1 pipe the inside of the pipe is the one making the noise i just change it today and there is no more noise

 

it causes a rattle like that? it seemed specific to decing rpms. This is with a stock y-pipe right?

 

yea stock y pipe i got a cattman y pipe and the noise stop

 

it's your timing chain, the things under warranty, bring it in or take the timing chain cover off..........

 

that is what a warantee is for, might as well use it while its still there.

 

lol..thanks yall..
im hopin its the y pipe!!!!!!!!!!!!!!!!!!!!!!

 

ill get it checced out

 

bump..............................

 

why are you bumping this? you still haven't taken it in to the dealer?
