Very Strange Noise.. HELP!

[[__--MUD--__]]

thats odd...First place I'd start looking is around the fan shroud. But your check engine light and only hearing it at low rpm I'd be looking at the valve train also.

W/ the truck in park at idle or low rpm, does it still make the noise?

Yes, at idle in park and at low rpm it makes the noise, hopfully its not something terible wrong. I had no idea autozone would scan it for free, im definatley gonna do that.

What do i do with the code once i get it?

So its definately in the motor if it does it in park...nothing in the engine bay that moves or can jump around while not moving.

I'd lay $5 your check engine like is probably a knock sensor getting tripped from the rattling the engine is making.

Do you know the broom handle stethoscope trick? I use the kind you can inscrew from the broom head and stick the end straight in your ear.



You can pinpoint engine noises that way. I wouldn't drive that mother ****er if I were you untill you figure out where the noise is coming from, trashed motor wouldn't be fun. I'd start by the base of the intake where it meets the heads. The next thing I'm pointing at is a lifter, push rod or rocker. Those will make a hell of a racket at low rpm if any of them came unglued. Start hunting around w/ the broom handle, it wont cost you anything. Just make sure you dont jam the end in the serpentine belt while its running. I've seen that happen before. Good luck!

Ok so i just took it into the dealership, they say its the catalytic converter that needs to be replaced at $800. also they need to clean the fuel lines ($300) or it will mess up the new converter, and they reccomend a tune up ($700) which changes out the spark plugs and wires etc..

I told him to hold off on the repairs until i can do some research. Does this sound legit? im worried it was just the bolts on the intake manifold that came loose and they are going to charge me for all these unnecessary repairs
