It depends upon severity i think

@@YourMotorCare Yes, but where do you draw the line on what is "severe" ?? To be SAFE, we must consider ALL EXHAUST LEAKS as "severe" -- because they are all DEADLY. Of course, we could FAFO, but that ain't ever a good idea. 😁

@@YourMotorCare YES, and because severity IS a factor, the "100 Miles" comment is NOT a good idea. For maximum SAFETY, Exhaust Leaks should be repaired IMMEDIATELY upon discovery. In other words: "Git 'er DONE !"

Thanks for the info!

Almost ALL stock mufflers will rust through, especially where the motorways are salted in Winter. I've found that the MagnaFlow Glasspack mufflers will stand up to the worst salty conditions for many years, with not even a hint of a leak or a rusted-out spot. The MagnaFlow's straight-through design allows for more performance and better fuel economy, although gains are minimal. Pro Tip: The LONGER the Glasspack Muffler, the QUIETER it sounds on the road.

10 years with an Exhaust Leak !?? You're not REALLY conscious, are ya !??

@SlikLizrd swear to God 10 years, it is a Dakota pickup so it wouldn't have been exposed to the cab as if it were a car

@@deandecastro7081 I ain't doubting your WORD, man -- I'm doubting your sanity. 😁 Carbon Monoxide doesn't know or care whether you drive a car, truck, boat, or airplane -- it's gonna KILL you if you give it a chance. DON'T give it a chance !! 😁

Usually can see it coming out the tailpipe, the pattern of your smoke

The EASIEST method is to start the engine and LISTEN under the vehicle with the Tail-Pipe blocked off.

@SlikLizrd so use something to cover the tailpipe? I have 2 so cover both? And see if smoke goes out elsewhere?

@@liquidh5226 If you have dual exhaust pipes, you cover ONE pipe at a time. I use a wet sponge to cover the end of the pipe. We're not looking for SMOKE -- we're looking for escaping gasses that are not easily visible. Good luck !!

What is your car doing

Very simple bring ur car 2 the doctor😎 = garage.

Yeah, it's a serious plague on KZbin these days.

This likely indicates hydraulic lifter issues - a common problem in high-mileage engines. The tapping occurs because worn lifters aren't maintaining proper contact with the camshaft. I'd recommend first checking your oil level and quality, as poor oil maintenance often causes lifter problems. If oil is fine, you'll want a mechanic to inspect the hydraulic lifters and possibly replace them. They can also check for related issues like worn cam lobes or rocker arms that could be contributing to the noise.

@ just done oil filters my self when car is in neutral I add gas no noise when I put on gear and give gas I hear noise any way well open when is ready to change next oil is a working car any way is it ok if I still drive it like that pulls drives perfect just the taping noise when I drive

If the noise only occurs under load (in gear) but not in neutral, and the car runs/pulls well otherwise, it's likely safe to continue driving for now. Just keep an eye on your oil level between changes and listen for any changes in the noise. While it's not an immediate emergency, plan to have it checked when convenient since worn lifters can eventually affect valve operation.

@@YourMotorCare thanks mate so when time comes to change them does the colander head needs to come out and all head gasket needs to be replaced or can the top covers injector be taken out and replace them with out removing the cylinder head

Sounds like you might have a clogged fuel filter or failing fuel pump, especially since the symptoms worsen under load (AC and hills). The P0420 could be triggered by faulty O2 sensors even with the new cat. Have these checked - they're typically cheaper fixes than the catalytic converter.

BS

The P013C code indicates an issue with your vehicle's oxygen sensor. This can cause symptoms like loss of power, stalling, and idling problems. It's best to have a mechanic diagnose and repair the issue.

@YourMotorCare I changed o2 sensor, bank 2 , same code again

Check compression in all cylinders . Piston rings must have jammed to the piston due to carbon . Check timings .

Thank you for reply, turns out it was an exhaust leak, I had my local muffler patch it up. The check engine light did go away but it's still not smooth acceleration

@@Nyckaka The muffler has nothing to do with loss of power , stalling or idling . If the oxygen sensor code is showing , which means there's something wrong in the engine itself . A muffler is only to reduce noise to make car street legal . Check the above parameters as discussed on my earlier post .

It sounds like you might be experiencing an issue with your wheel bearings or possibly a problem with the CV joint. It’s best to have a mechanic take a look to pinpoint the exact cause and ensure your safety!

Great idea! A small battery booster is definitely a handy tool to keep in the car boot for emergencies. It can save a lot of stress when the car won't start.
