All the engine stickers ive seen that are still in tact are on the drivers side valve cover. They have a month,year, and serial number on em

 

My 97 California had a sticker on the HPO reservior with the engine serial number and a bar code. No sticker with serial number or build date on valve cover.

Thanks Chris,

There under my I/c pipe is the only pic I have where you can see it, its the white rectangle under it. The top "layer" of the sticker had peeled away, which I atteibuted to me power washing my motor a few times a month to keep her squeaky clean

 

This motor is in an obs, reason it has no sticker is years ago, our ford dealership had a bunch of original 7.3 complete factory motors laying around that my shop bought, and for whatever reason, they didnt get those stickers im talking about, but got that powerstroke sticker

 

No sticker on the DS valve cover of mine either since new.

 

ghohouston, you have to realize that there are quite a few differences between the OBS trucks and 99+ years of trucks and this is one of them.

I have had my truck since new and it never did have that sticker that you speak of.

 

Okay guys I was wrong and i admit it, like i said, i havent been under the hood of that many obs trucks. I do understand the obs and sd motors are different in some aspects

 

all of the obs that I have seen have a emissions sticker on the passenger valve cover stating hp and emissions info.

 

All 7.3's have that

 

So to make things even stranger, here's some pics I took of my buddies 97 today. Original engine, 150k ish miles, no hpop res sticker, but clearly has valve cover sticker.

 

The date on that sticker makes it a late build August 97 year engine. The late build trucks had some of the e-99 type stuff on them. Check the build date on the truck, its probably tail end production between Sept and Dec. 97. The last OBS diesels were built about mid-December 1997, the e-99 SD commenced production after that.

Oddities include the use of the small SD type engine cover, possibly also the update black intake hose instead of the orange hose to the turbo and the sale of the California splitshot engine in east coast trucks as the factory depleted OBS engine stocks and parts.

My 97 California and 97 Federal engines do not have that sticker, they have the one on the reservoir. thay are both early 97 year engine build dates.

 

The sticker on the above driver's side VC looks like the sticker on the HPOP Reservoir on my trucks, 97 and 96 (late 95.5 year).

BTW that is a clean looking under hood does he even dry it?

It is the same sticker. And yeah, he drives it daily, and even takes it mudding, just power washes the motor often

 

And my 97, build date on the door sticker of 4/97 has the sticker on hpop resovoir. Ill ask my buddy what the build date of his truck is

 

I think the "switch" to the new model year is September No? My 96 door build date says 9/95 and was sold as a 96..... The engine serial is 0220885 which I think makes it a 95.5 nearest can figure. Still not sure if it has the anti drain on the HPOP and have not made time to check the PCM code. Based on calibration code on door (6-90A-R02) might be a NAW4 which is 95 factory tune I think.
