Engine knock noise though no performance issues. Knock tends to go away when a/c compressor is activated.
There is a loud knock in the engine, it has been going on for a few months now. I took it to an auto repair shop today and they told me it could possibly be the drive chain...not sure! I will be getting a second opinion because they are trying to tell me the labor alone is $1300.
We haven't gotten it fixed yet, but have noticed a "clunking" or knocking sound coming from the engine. I'm hoping this is the issue, ours does it even while cold though. Hoping it's not the tranny!
Disgusting noise when car is not yet warmed
