2003 engine rattle on shut down
this started a couple of weeks ago. when i turn off my engine, there is a short rattle. motor mounts have been replaced. this sounds like it is coming from the engine. i haven't had a chance to open the hood and have someone else shut the car off so i can get a better idea, but just thought maybe this was something simple.
timing chain tensioner?
191,000 miles regular issue?

my freinds car rattled on shut down and it sounded like from behind the engine and it turned out to be an exhaust hanger holding the flex pipe was broken. make sure nothing moves down there and nothings broken.

sorry about not posting the vid. i'll try to get one up soon. it makes the noise when i shut the engine off. im pretty sure my oil is good but ill give it a look here when i go to work. it also makes the noise when i rev it in low rpm. always suspected pre cats but this sound is a tad worse and it never did it on shut down. im hoping precats but i fear bad timing chain tensioner.

aight just made the video. checked the oil, its fine. what im talking about in the video is the car wont usually stay started without a little gas pedal. i figure thats more the maf and intake needing cleaned. will attempt to upload vid now.

A friend's 2003 Max does exactly same. It seemed to have developed when the spark plugs were changed and new ones (oem) installed, though I think the change is more coincidental than connected to the problem. It is really difficult to locate the sound. At one breadth it seems to come from the top of the engine bay at another you'd think it is from somewhere lower on the passenger side.

some confusion here. The tensioner itself might whine but the sound here from a bad tensioner is chain slap since the tensioner doesnt have enough tension on the chain. Somewhat of a common issue on 5.5 gens, particularly in winter when startup temps drop and it takes longer to get oil pressure built up in the tensioner
