I've searched the forum and my manuals and can't find the answer to this one. The 4.0 in my 89 XJ has 5 - 2" freeze plugs on the manifold side of the block. The replacement engine I bought, which was already out of the XJ, has 3 - 2" freeze plugs and 2 - 1" freeze plugs between them. This engine still had all the Renix gear on it and I was told it came out of an 88 XJ.
So, did the block casting change between 88 and 89, or am I looking at a 4.2l engine? Everything seems to be the same other than the freeze plugs.
