I own an 84 Bronco II that I really love. It's taken me places no normal person should ever go. But as it ages it has a few problems. Gas mileage isn't too good at all. But the big problem right now is an oil leak. The front oil seal has taken to leaking. A lot. It spewed enough oil out to ruin my alternator, so it's time to fix it. My question is how big of a job is this going to be? Is it something I can do myself, or do I need to take it to a shop? Am also curious if I can put a carb off an 86 on this engine? Same engine size so I'm hoping it'll fly. I have had an 86 with a hole in the block given to me, and was hoping I could swap parts. Any ideas gang?? Thanks in advance, John.
