Why would a lighter flame go into an exhaust pipe?
처리 내용
This is a quick-n-dirty test done to see if there might be an issue with a burnt exhaust valve. Another similar test uses a dollar bill (or whatever currency you happen to have). What is being checked for is reversion . This is an issue where if the exhaust valve is open when the piston is on the intake stroke, there will be the situation where exhaust gasses are pulled back into the cylinder along with air/fuel from the intake tract (with a non-direct injection setup ... just air with direct injection). If there is reversion, the flame from the lighter will be pulled into the exhaust pipe when lit in front of it. In the dollar bill test, the bill will rattle against the exhaust pipe. Reversion can happen in one of three ways (that I'm aware of): Burnt exhaust valve which no longer seals correctly. Stuck exhaust valve which doesn't seat correctly or gets stuck partially open (which will quickly lead to a burnt exhaust valve). Large amounts of overlap in the cam. The great the overlap,

My Pilot is lighting up a catalytic converter code on the dashboard. My Boch Honda dealer service is quoting $1,037 for the replacement part and more than $600 for the labor. Does that make any sense? The car has 180,000 miles on it. Should I just go with non-Honda parts?

I drive a 2004 Ford Ranger, which I’ve had for the life of the truck. For a few years, I’ve had the CEL on more often than not, usually for codes related to oxygen sensors and cat converter. I’ve taken the truck to a couple of shops and had O2 sensors replaced (repeatedly), but the CEL has come back on within a few days. I’m not at all experienced with auto-work, but I’ve been trying to pick up some new skills (in the interest of not going broke). So, aside from the shops doing their work, I’ve personally replaced a couple of O2 sensors, one catalytic converter, fuel filter, plugs, etc. Betwee

My 2005 Buick Century with 353k miles gets a recurring P0420 code, catalytic converter operating below efficiency level. Twice this year, I tried using Cataclean, but with no success. I noticed a small hole in my muffler at the seam. Could a lack of exhaust back pressure cause the CC to operate inefficiently or improperly? Can anyone recommend a catalytic converter cleaner? Or, is it all snake oil?
