While working on my truck today I noticed the tag on the passenger side valve cover said: "engine is certified for sale in California in new vehicles rated above 14,000 GVWR, engine is OBD II exempt." So does this mean I have a California truck or do all 7.3s tag say that. Plus what does OBD II exempt mean? Also any links on diffenances between California and normal trucks.

Thanks everybody

 

i don't know on the 7.3's but on the 6.leakers there was some programming differences between a 49 state and a CA truck along with some slightly different emissions junk. there also might have been less power output on a CA truck.

 

The tag read 215hp at ?rpms but as far as emission stuff it'd be hard to tell since I got this truck I had to swap exhaust and unless it's programmed diffrent I can't tell what else would be there for emission stuff.
Anybody know if the Cali trucks were split shot injectors vs. single shot (thought I read that somewhere)
Any ideas if I can decode the VIN to see or if I need to try and find an engine ID number.

 

Cali trucks were split shot AB injectors... Roughly 120cc

There are a few ways to tell if your truck is a cali truck... One way is to look between the fuel pump and the turbo and if it has a black diaphram on top of the fuel fitting (looks like a little space ship) it is a cali model. Another way is to remove a valve cover and if it has AB code injectors, you will know its a cali model.

 

Yup, 96 and 97 OBS came with AB injectors (split shot) which gave them (weird) more HP then the fed trucks with AA injectors (90cc)... Also from 99 on the cali 7.3's came with a damn Glow Plug Controler rather then a Glow plug relay!

 

Well judging by all the info and the following pics I don't think mines a Cali truck - just trying to find out for repair /mod purposes

No "spaceship" unless I'm looking in the wrong spot




No shunt on the GPR


And a black engine tag - guess the Cali's were blue


Just still trying to figure out the for sale in Cali and OBD II exempt parts, since my truck is 8800 GVWR and the tag is for 14000GVWR

 

Looks like a 49 state truck with that valve cover tag and a regular glow plug relay with no shunt on it...

The "space ship" fuel dampener will be straight behind (towards the firewall) the fuel bowl and underneath that intake spyder if it is indeed a cali model.

The valve cover tag might not mean much though because it looks like that engine has been painted yellow at some point.

 

do you not have a pre filter?

 

That is not the motor that came with that truck... Hard to say what it is, but I would bet its a bus motor someone swapped in. Could even have AC injectors in it.

 

I was told the origonal owner pulled the motor to put a new oil pan on and painted the motor. but who knows. I have a number (TNV7.3C8DAAA) from the tag thats under the International name, going to see if it turns up anything. Where would I look for say an engine serial number to see what it is. Would a bus motor bolt to a e4od without some mods?

As for the pre filter ya lost me-pre filter on what?
