I have a 1991 4.0ho eliminator and plan on tackling an engine rebuild next month. I'm going to drop the pan, again...(I replaced the rear main seal last winter) and need a new head gasket anyway. While I'm in there I'd like to replace the rings as shes burning more oil than I'd like.
Is there a "tool of the trade way" to determine what size rings to get? I'd obviously like to get them in advance but I head rumors that back in the early 90's Jeep wasn't the most consistent with their assembly process. I do not want to get the wrong ring size. Also, does anyone have any leads on a good brand to buy?
