4.0L gas engine sounds like a deisel
I have had this truck for about 3.5 years. I first noticed it sounded like a deisel not too long after I bought it. I haven't had the time or money to investigate the problem. I was thinking it could be the lifters, exhaust leak or some other common problem I don't know about. It seems louder during idle, than when I am excelerating. I am looking for any serious suggsetions on what it may be, before even attempting to start looking. The truck in question is a 1996 Ranger XLT, has had an engine swap, a 4.0L from a Ford Explorer if memory is correct, replacing a 4.0L original. The original mileage on the newer engine should be around 200-224,000KM. No mods done, all factory. Please do not post you have the same problem, only post answers to resolving issue!
