CO 70s Owners, diesel question (6 Viewers)

[sgmartz]

Hi all, I found a great 1993 HJZ77 with AZ title. I am considering purchasing for my use in CO. From what I can tell, it would be subject to diesel emissions testing of 20% opacity. Anyone in CO have any problems meeting that? If so, have you tried the out of state Dakota or Montana loophole route? Thx in advance!

While I am in AZ, last opacity test w 1hdt circa 2008 was 1.5%. Cutoff was 30% in Pima county. I registered in non test county after that as it took more than 1 hour to set up for test which was on treadmill at 40-45 mph.

Anyway, auto or manual? You will probably hate an auto at altitude with 1HZ.

Manual trans. Opacity limit is 20% in CO

I can speak for a 1KZ. There has been no issues getting it to pass and besides being up to date on maintenance there has been no extra effort on emissions. If the truck isn't passing emissions I would wager it is unhealthy engine, and needs some TLC anyways, just my two cents. I would say the only thing that differs compared to a newer gas vehicle is diesel of that era has to go in for a yearly emissions test instead of every 2 years or getting passed by the mobile checks. I've spent more time getting the FJ40 to pass emissions than the KZJ78.

Owning a diesel in the emissions areas of CO has been pretty straight forward if you aren't doing anything silly/shady and once the extra paperwork is filed at the beginning it is all the same. And to be honest I would have to double check if that extra paper work was only because it had been imported not because it is diesel. I would say I see a new to me imported diesel Land Cruiser at least twice a month with CO plates in the emissions areas, and I would doubt most are registered out of that zone.

1997 HDJ80 with 1HD-FT. Just passed emissions on Thursday. No problem. Opacity spec has always been 30%, but now they've changed it to 20%.

Agreed. Either unhealthy or it's been messed with.

I would have to double check if that extra paper work was only because it had been imported not because it is diesel.

Emissions Technical Center in Denver inspections are for "gray market" (i.e. imported) vehicles. I doubt they're running every diesel in the Colorado Front Range through there.
