Is it a safe bet if a GM style (6.2/6.5) v-8 diesel has a General Engine Products LLC sticker on the valve cover that it would be a 6.5 ?
Did GEP ever produce the 6.2 ? The engine is not here yet. Just wondering what I got. Thank You
GEP has only made 6.5's, but you never know if somebody just swapped valve covers, especially at a rebuild facility where they all might get tossed in a pile then pulled off.
The factory GEP RTV on the valve covers is some sort of super strong miracle adhesive, I bent my valve covers trying to get them free. But I have a GEP 6.5 in my 94 Chevy pickup now with the standard civilian turbo and IP and it runs like a top.
What are the casting numbers on the block under the intake? That is the dead giveaway if it is a real GEP is that the blocks they use are all cast by Navistar (except maybe a few very early ones) and they have the Navistar/International Diamond logo cast in the top of the block there.
