I have bought a Chevrolet cobalt 2007 for 3000$CAD. I now have an issue with; either the timing chain or the engine. I'm hearing a loud knocking sound from the engine. I can hear it on the idle and it goes louder and faster when the RPM goes up. Should I repair it or just get a new car?
Hi, The loud knock you are hearing is typically refer to as "spinning a bearing" OK, sounds like that's what is supposed to happen I know, BUT, the bearing is called a shell hearing, it is the bearings that are used in the connecting rod to crank connection.. Now, the repair... it is most common to replace the engine in these cases. You can expect around $3000.00 to $ 3500.00, replace the engine.
If the repair costs more than half the car value, it is generally a good idea to replace the car. There is likely something else like brakes, wheel bearings, burning oil (compression) issues, ...
