I had convinced myself that driving around in my 1994 YJ with a 2.5l, 3.5 in lift was ok with me. Well what’s the old adage, ‘man plans, god laughs’. My engine exploded the other day. I mean I started her up and she rev up to 6000 rpm when I started her, then all of the sudden, we all this God awful metal grinding sound and a chain snapping, then the smell of oil e everywhere. The little 2.5 l had had it. So now I’m putting in a Chevy LS 350 V8. Ugh.
