So my head cracked and I bought a replacement on ebay that was supposed to be off a 2004 WJ(I was told it was off the original engine). I was under the impression that all the newer heads had "TUPY" stamped between the 3rd and 4th cylinders. This doesn't seem to have TUPY on in. Am I looking at the right place? Or did I get ripped off?(I just opened it, haven't cleaned it yet)
This is what it looks like:

Between 3 and 4


Cylinders 1-3

3-6(I think might be Backwards)

 

what are the casting numbers on the replacement head? Does it have the bosses to mount a coil pack?

 

Its 0331, (sorry bad pic)

Yes it has the correct bosses.

 

I'm no expert but I not believe you got what you paid for.

 

Sorry....that did not come off of a 2004
