Anyone Know About E-Check With Diesels?

I'm looking at a 1997 F350 with a diesel. It has an aftermarket exhaust and no catalytic convertor. I'm not sure if that will pass the visual inspection at the E-Check station however. I'm trying to determine if the truck was originally equipped with one but have been having a hard time confirming.

The engine has a sticker that states the emissions control system includes "ECM, TC, DI, OC". I think "OC" means "oxygen catalyst" but not positive. If so, does that mean this truck was equipped with a catalytic convertor and I would need to install one if I buy the truck to pass E-Check?

Would a Ford dealer be able to confirm this?

I do not believe it had a cat on it. With the waste from burning diesel the particulate matter would clog a cat. I do know it probably had a resonator on it before the muffler which some think is a cat. The ford dealer will be able to confirm or deny. I'm a Cummins guy and they didn't start with a catalyst til 07 with the dpf filter

To my understanding there is no more Echeck in ohio unless you live in Cleveland where the last echeck station is

Eh, wrong! :D

They're still active in the same seven counties including Summit where I live.

I'll have to get my '09 Ram Hemi tested this September. :cry:

Surprisingly, my FSB passed with flying colors last year with the original emissions controls and cat from 1990.

It looks as though it did have a catalyst, not 100% confirmed though.

From a Ford Trucks forum:

OC = Oxydizing Catalyst (Catalytic converter that controls CO and HC does not control NOX)

The catalyst on the newer trucks other than the particulate filter, is a NOx catalyst.

well, you learn something new everyday. The echeck place around here, Dayton closed down back 3-4 years ago, even my wife said they stopped requiring people to fill out the echeck paper work for a license renewal at the BMV when she was working there

Cummins trucks had cats before the 6.7l

And a 97 never came with one.

And for being in an e-check county :dumb:
