engine identification site

in the midst of my tear down lastnight, i ran across something odd

seems to me that these numbers may have been changed?

*** is up with the grinder marks.

they look too uniform to have been done by hand.

anyways is there a site that i can decode this number from?

thanks guys!

(1/2 hour of searching only brought up other questions like this no definitive way to decode.)

oah yea, all that oil is compliments of ULTRA GREY.
that crap i was told to try,
"its wayyy better than ultra black" they said.
that crap hardened up and cracked,
back to ultra black i go.

What is that number???? It doesn't look like any IDI Serial Number I've ever seen.......

They are normally:

6.9##U#########
7.3##U#########

Not sure how many numbers follow, but they all start with the displacement, and the U which is a universal IH code means it was made in the U.S.A...... Just like on my IH Cubs, the are 2####U###### The numbers to the left are model and kind codes, and to the right is the actual, in order, serial number.... the U in the middle means U.S.A. as all IH Cub Cadets were made in Louisville......

Look at madpogues in this thread:

It is 6.9DA2U799736

Fortunately this rebuilder didn't attach a tag with rivets into the water jacket. Too bad the original numbers are gone.

That is a reman engine block for sure. Why a company does this is a wonder. No matter what serial number is on the blocks oem. a reman company can easily use them. But maybe its ego that makes them change them. Number wont change by themselves.
As for a great rtv sealer I have used permatex ultra copper plus for many years with never a leak. Its a high temp and oil resistant sealer. Its a reddish color and smells bad but it works. You just need to be sure the surfaces are surgically clean before its applied. Brakclean does a great job of cleaning and leaves no film or residue.

i rubber wheel all surfaces then wipe down with acetone..


i will contact some of the vendors that reman these blocks and see if i can shed some light on it

I know I've seen that "format" before, just blanking on where/when.

I can understand a reman-er wanting to use their own numbering scheme, so they have a "serial" database of numbers to work from. But like my wife said, couldn't they just pin a tag down on an intake manifold bolt? Or even one of the IP cover bolts? Idunno if grinding down the original number is worse than riveting a plate over it, or vice-versa. To me they're both

Acetone is not all that great at cutting grease/oil residue...it's fantastic for cleaning up Iso/Orthophalic resin...aka fibreglass resins.

Better to use Alchohol 99% Iso than acetone...or brake clean..imho...

And you are in possession of a motor vehicle part with altered numbers.
