New Cat time?[240-260/1985] posted by Paul S. on

The cat. on my 245T looks original. The car has 187,000 miles. To my knowledge, the thing has never been changed. I worry about the darn thing being partially plugged more than I do about it not being an effecient catalyst. (Shame on me).
I know the Cat isn't completely plugged, but I don't think the car breathes as well as it should. Anyhow, what are the symptoms of a marginally (barely) plugged catalytic converter? Any DIY tricks to help detect plugage?
PS Please don't tell me to route the innards out of my existing Cat. Al Gore wouldn't appreciate it.--

I had to replace the cat on my '86 245 about 1 1/2 years ago (110K? miles) when the catalyst ball inside came loose and entirely plugged the exhaust flow. It was no fun having the car die without warning from highway speed to stalled on the shoulder only to have it start and run fine because the exhaust flow stopped and the ball dislodged. This happened a few times before I figured out what was wrong. I ended up removing the lower plug in the headpipe for the "other" O2 sensor so that I could drive it to a friends to do the work. I got a cat from Trak Auto for $100 and it went right on without a hitch. Haven't had any problems with the VA state emissions test with this cheap cat. Don't know if the Turbo is the same but for $100 the piece of mind and safety may be worth it.
