My 2003 honda crv had it’s cat stolen in 2022. I got it replaced and almost exactly a year later the new cat starts making rattling noises and the computer is running an emissions system code. I get the cat replaced at the same shop and now almost exactly a year later again my cat is rattling.
What could be disintegrating my cats? Is it because my car is burning oil? I’m sick of paying for a new one every year.
I’m going through about .75 quart a month but I’m not sure how much of that is being burnt vs just leaking out. There is a noticeable oil leak on the passenger side of the engine.
About 17-18k miles
I’m pretty sure that it is a cheap aftermarket cat. The shop I’ve been going to charges about half what other shops have quoted me for the fix.
