Thanks guys. I had my mechanic swap the post cat O2 sensors. If the fault moves with the sensor, we know the O2 sensor is bad. If it doesn't I'll buy used pre-cats/headers. I drove around a little, but thus far the CE light hasnt' come on yet. And I'm going on vacation for 3 weeks, so the car will be sitting for a while. We'll see when I get back... Thanks for all your help thus far. This place iby oscholz - Main Forum
More advice needed: I went back to my original mechanic. I've been going to these guys for 5 years, and they are very knowledgable, but I do want to ask you guys, especially Boxsterra. They did the smoke test the other guys did, and there were no leaks/cracks in the catalytic converter. No smoke came out anywhere. There were some very light deposit around the top of the manifold/primary cat headby oscholz - Main Forum
Ah! I get it now. Well, if somebody here has a primary cat/header they want to get rid of, I need one.by oscholz - Main Forum
I am still a little bit lost on this. Maybe a little mre than when I started out. The piece that has the crack, and that needs to be replaced or fixed looks like the one here The cracks are in the two outer pipes of the manifold. The challenge I have is that the part that the kind people here have offered me look more like this Naturally the two look nothing alike. My mechanic tells me thatby oscholz - Main Forum
Oh, the second/current mechanic did inspect it while the car was running. He said he heard a sound. Then he turned the car off, put the smoke thing on the tailpipe and blew smoke into the exhaust system. Then he found the cracks by looking at where the smoke came out. When they weld it, do they do that while the cat is on the car? (I can't imagine that). Otherwise, there'd definitely be the laboby oscholz - Main Forum
I don't know the actual codes. All I know is that the CE light kept coming on, and that the first mechanic replaced the rear oxygen sensors, then wanted to replace the front ones. Something told me that didn't make any sense, so I went to a different mechanic who blew smoke into the exhaust system from the tailpipe, and found the cracks. They are telling me I should replace the cat, or I could weby oscholz - Main Forum
The engine light has been coming on for well over a year, and my mechanic said that the cracks having been there for that long probably caused internal damage; oxygen going in and corroding the internal membranes of the cat. Seemed sensible to me. No?by oscholz - Main Forum
My mechanic tells me that the driver's side catalytic converter on my 01 Boxster is toast. They did a smoke test on it and diagnosed cracks in the cat housing. This causes the check engine light to come on all the time. I don't want to spend $1750+ on a new CC. There's got to be a better way, and I'm hoping that somebody here can help me with some advice. Are there good aftermarket CCs? How abouby oscholz - Main Forum
