2003 Dodge Caravan 4 cyl Two Wheel Drive Automatic

My van has been making a rattleing sound for about a month & has gotten louder over time. Last week it started have loss of power when driving under 40 mph & stalling a little at stops.
I was told that it sounds like a bend valve.
What is the cost to repair? Is it something my husband can do or sould be take it to a shop?

Other than the noise, is the engine still running okay? A bent valve will cause a constant miss. Is that what is happening? Also, I want you to take a rubber mallot and tap on the exhaust system to see if the inside of the catalytic converter is loose causing a noise and causing a loss of power. Also, let me know if you can tell aprox where the sound is coming from. NOTE: I need to know the engine size because a bent valve usually isn't a problem with these vehicles.

Let me know.

Yes the engine is running good beside slight loss of power at times & noise. It is not causing a constant miss. The sound seems the loudest underneath but the engine is so small & compact it's very hard to tell where it is coming from.
It's a 4 cylinder.
My Husband changed the oil & put in SAE 30 & Lucas heavy duty oil stabilizer & it didnt change anything at all.
We'll check the Coverter in the morning. Thank you!

My husband tapped on the exhaust system & we did hear a faint rattling sound with the car off. He said it does sound like it is coming from that direction.
Sould I take it to a reg. Shop & have it checked out first or straight to a muffler shop? Whats the average repair/replacement cost of that?
Thanks!

If you hear a rattel from the converter, it may be loose inside. I would have it checked your regular shop.

Let me know what you find.

It's a very, very loud rattle & it seems to be coming from that area. When we tapped on the exhuast system with the van not running we could hear a very slight rattle.
Although I think it seems to be coming from that area I have had my father in law tell me several times he thinks it's coming from my engine.
It started about two months ago when we took a family day trip up to the mountains. When leaving I heard it. But it wasnt very loud over time it has gotten louder & louder. It is non-stop when the van is on. Have you heard of this before if it isnt the Cat. Converter what else could it be?
Thank you!

A knocking or ticking could be an internal engine problem. But, although that can lead to major engine problems, usually you don't lose power. That is why I thought maybe the inside of the converter was loose and partially blocking the exhaust. That will cause a power loss.

I had a trusted Mechanic come check it out this morning & he said it is the motor. He said he can replace it for about $1,500 parts & labor. He thinks its best to get a new motor & not one from a salvage yard.
Your thoughts on used motors?
