I got a 02 Grand Caravan Sport with a 3.3 and 137k miles. Got it 10k miles ago and have recently noticed there is a ticking/clicking noise coming from what sounds like the passenger side but only when I accelerate. It doesn't do it when in park when I rev the engine. It does it whether I'm going straight or turning. The tick gets louder as I accelerate but it sounds more external or on the side of the engine then coming from the top where alot of ticking usually occurs.

 

Check the area of the flex pipe.

 

I'll take a look today. Anything specific I should be looking for/at?

 

Check for an exhaust leak. If the flex pipe is the issue, it expands when it warms up and seals the leak which is why you would only hear it when cold.

 

All of the above OR one of the exhaust manifold bolts has backed out. Seen that a few times too.

 

its been cold, wet and snowy so I haven't checked yet. The noise is there cold or hot.

 

It's so cold here I don't even want to get gas.

 

isn't the cold that bothers me as much as the wet and snow on top of it. Wish i had a garage.
