I am trying to figure out what was done to this engine when it was rebuilt. Anybody identify the rebuilder by this tag. It is a Southern California Car.

The same style tag is on a 1.8L long block I acquired a few years ago. Someone else posted a pic of their engine with the same style tag a few weeks ago.

GEX is one rebuilder that applies a tag, but I don't know if that is their tag or not

GEX used to stamp the side of the case with their logo. Down towards the oil pan.

You could look there also.

I've seen that tag up here as well.

I know that it can't be a VW reman tag, they used to stamp a small logo and another number. This is a early logo the later Canadian logo was smaller . Most type 4 remans were a sticker. Most of the NA reman engines were done in Canada.

car craft in riverside use to use those tags.

cked with car craft - not them. Any other ideas?

Take a chisel and cut the rivets and find out the factory number underneath. Since it is near the oil filler neck I am guessing it is a GA, GB case.
