Hey no argument there, and that is a beautiful car. I've spent a lot of money putting in crate big block motors into vehicles that I kept or planned to keep. However, some guys love their cars no matter what make, model, and year they are, no matter what the pedigree.
NOx a problem????? Not anymore!!!!

Q, I did use water and seafoam at 282 k miles after a borderline fail on NOx. Guess what? I reduced the numbers by over 60%

Thanks for the compliment, and I dont disagree at all... if a 91 corolla is in top shape, (or whatever the vehicle may actually be), great - make and model isnt an issue - the problem is ****ing a car just because of its age and the concept that saving for the next one is more important than properly maintaining the quality old ones... Given the cost of putting high performance new engines into cars (fun!), you obviously understand.

Believe me, I've taken a lot of grief from friends, family, and co-workers who cannot for the life of them understand what I'm doing. Not that I care what they think, sometimes I know I'm irrational with my automotive purchases, but if I'm happy with it that is all that matters. However, it IS funny knowing that I now own a $1000 old Blazer with a $15k drivetrain!

I reduced the numbers by over 60%8 yrs of stall and crawl commuting 31 miles in 1.5 hrs carboned it up big time. The first 10 minutes of that drive were at 70 mph. It got to operating temps, then basicly crawled from there
IMO, it is a bit of each. In my car which otherwise burns no oil whatsoever between changes, if I WOT it at night with a car behind, I can see a little bit of junk coming out - its identical to what my diesel does at WOT, which is dump fuel and let out a lot more soot - but I have to assume that some of what I see (in either case) is actually carbon from the CCs, exhaust system, etc.
That said, my father NEVER WOTs his vehicles, and pases emissions without any problems at all at well over 200k. It is a highway car though, so long term use, even with gentle, lower RPM driving is still fine.
Further, I would suspect that one would see an increase in compression pressure if the CCs were carboning up, right??? I never saw such a phenomena in my vehicle. Id also assume that one cylinder would carbon up more than the others, due to hot/cold spots, etc. when driving in these bad conditions... but this would yield a difference in compression, which I did not see either. In fact, the CCs are quite clean and like new, and the compression is in the correct range and consistent across cylinders, despite my easy EPA-surpassing driving style, and short commutes.
So I think that both angles are plausible... and make a lot of sense. Unfortunately, my emissions did not improve despite using about a cup of water in the engine. Perhaps my technique wasnt good though - I never get this grand white cloud like others claim to get...

Hey guys I never dreamed of insinuating that any car is better than any other. If you really like any car and plan to keep it indefinitely than a 1200 CAT is within the realm of reasonable.
I was merely trying to introduce a different approach to a similar situation.
I got that 91 rolla used from a family member late in its life. I was unsure of its maintance record. It needed A/C work on top of the NOx issue so 350 for a CAT (cheaper than BMW) plus whatever I saved postponing a monthly payment for 2 years (then 2 more as it turned out) made sense.
I know Quest is LOLing allover the place on this thread with the italian tune up and the mechanic in a bottle approach. But so what. It worked(s) for me!!!

LOL Trixman-
You haven't see me challenging those big BMWs with my stock Suzuki with a tweaked carb in autocross racing with WOT all the time?!
*evin grin*

Sorry, really didnt mean it that way, or in a mean way. The way most people look at repairs on old cars is the cost of the repair vs. what the car's book/trade in valuation is. At that point, most do 'good enough', and for a reason. That is all.
A car that has value (regardless of age) will in general get better/more parts, maintenance and attention than one that has little (perceived) value. IMO, that is the difference between doing work that is good enough to pass and get by to allow saving for the next one, and doing work to keep things as new to maintain the status quo so that replacement doesnt need to be an option for a long time.
Im sure you made the right decision, given your situation and vehicle, and I made the right one given mine. Glad it worked out for you so that you could keep it going and save money for the next one!

It's all good.
right back at you.
Basically everything has already been stated about this topic. Nice car. My friend has a 91 325xi he's re-doing. And he doesn't have to pass emissions with it here in NY.
OT: Erie County, NY has an 8.75% sales tax and we have to pay for our inspections. Yes, it sucks.
