Any mechanics here? (1 Viewer)

Car started making a noise yesterday. Need to rake it into the shop tomorrow, but I was hoping to maybe get an idea of what it could be, or eliminate things, in case the mechanic I see tries to get over on me. I know a good amount about cars, so I should be able to explain the symptoms fairly clearly.

What are the noises? Where do they come from on the car? Does accelerating or braking cause them?

By all means, don't explain it in the op...

   This is the part of the program where we start guessing what the noises might be.

So I was driving down the freeway amp didn’t my car started sounding louder, for lack of a better term, like a deep hollow sound. I immediately pulled off the freeway and parked. Now as the car is idling, it sounds normal. There are no misfires no rod knock, no clicking, not even a rough idle. I rev the engine a little, nothing. I start heading home because I DID hear something. It’s about a 30 mile drive. I am taking surface streets as much as I can. I stop every so oftempn to listen. The loud sound is getting worse, but not a lot. By the time I get home it is now noticeable when idling, but just barely. 

Other details:

No loss of power. Even at 65 mph.

No check engine light.

 Car temperature was normal, so no overheating. 

No smoke of any kind.

i am hoping it isn’t something too expensive. I’m pretty sure it isn’t a blown head gasket or a bad cylinder as there was no power loss and no over-heating, but I that’s about the extent of my knowledge.

I was hoping someone would check in and we could take it to PM’s. I didn’t want the random “Does the car have gas?” Or “Check the tires” replies...

Loud sound? As in engine noise louder? Metal sound?

Can you isolate where the sound is coming from?

Sounds like exhaust leak

Imagine you were at my station and you brought your motor to me

I'm going with "hole in the muffler"

 

[Kal El]

Sounds like a bad muffler, or a hole in the exhaust system before the muffler itself.

This is the answer.

This is what I was thinking, but I don’t know enough. I hope it doesn’t cost too much to fix.

They're not horrible, probably a few hundred depending on where you take it.

Does it sound like the beginning of Hot For Teacher? When I was a kid, my parents had a car with muffler problems that sounded like that.

Year / make / model of the car?
