Wow - caught the subject line in the "new posts" and I recognized the thread as one I was going to use for reference..... Didn't remember posting
Yes- the XJ runs GREAT and everything works. Good stuff and feel so fortunate to have picked up the rusted out XJ!
Haven't pulled the XJ's 4.0 yet though as I am working on a frame I bought for the project. I got the 258ci/4.2l apart for the donor crank (I wanted the 12-counterweight crank for my stroker build). Basically doing everything I can with my "loose parts" since it is too cold here to do the "outside work" necessary before the rebuild can be brought inside where it's warm.
I *do* have a 1993 4.0 out of a junk wrangler which I am probably going to strip and prep. That way I can have it hot-tanked, bored, etc. and have a short block assembled and ready without having to deal with the '98 XJ until it's warmer. I am pretty sure the blocks are the same- but I will use the 98 head and cam, intake/injectors etc.
I also bought an unused rebuilt 4-counterweight 4.2 crank still in its shipping box - complete with bearings. I picked up a basically stock '89 YJ with a 4 cyl to drive for the winter I thought I would put the 4.2 in it this summer because I am not thrilled with the 2.5's HP. I have enough "spare" AX15s and such from all my trades that it really won't need any parts purchases. So why not? Plus- letting that ol' 1978 AMC 258 a have a second life gives me warm fuzzies. Yes, I am sick...
Thanks for asking and thanks for all the great info in your thread. There's a lot of stuff that here that has helped me in my planning and collecting for the project jeep!
