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.
