engine size

I've had my 91 for about 2 years now and the engine is all gunked up and I've always thought it was a 4.0 but today I was told it was a 4.2 .......how can I tell the difference in the 2?

If it's carbed it's 4.2. If it's fuel injected, it's a 4.0. At least, that's my understanding.

They used the ax5 with 2.5l and ax15 with 4.0l, so you have the ax15 with the 4.0l.
Let me tell you about Time Machine: 95 YJ Rio Grande Edition l4 2.5l on 31s stock height springs from GS, Warrior Products .5" shackle lift, Softopper tan soft top, daystar 1" body lift, Spartan locked D30, open D35 with 4.10 gearing
