My xj is a '90 model well atleast that's what the title says. When I first got it I went to do an oil change only to find out I had the wrong filter. By the book fram for example (and no I do not use fram filters) says a '90 takes a ph3985 I believe, but mine takes the '91+ ph16 filter. I'm really just confused by this. It seems that everything I get for the engine has to be looked up as a '91 model. Did they put '91 model engines in some '90 models or something. That I know of it hasn't had a engine transplant, but I did get the truck with 189k miles on it so that could be a possibility. Is there anything i could look for like casting numbers or something that would tell me exactly what this engine is. I like my truck but I've come to figure that in this year model it's like pulling teeth trying to figure anything out about it. When you combine the engine with renix and an aw4 tranny it can be just mind boggling. Any help would be appreciated and I do mean any.
