If its the bronco XLT you'll have to take the tail gate paneling off the inside. The motor, gears, etc. for the rear window are located in there. I had the same problem with mine sometime back.
the pcv is at the back off the engine under the upper intake in the lower intake
See the link below.
All of the full size.
how to remove oil pan from 1989 bronco 2
look at autozone.com for great repair manuals online on the firewall right behind the intake, there is a cover with 3 screws. take the cover off and here is one nut holding on a small place with a slot in it. just line it back up and put the nut back on. much easier with the intake off.
yes it unbolts and comes right off. you will have to take off the wind shield wiper motor cover.
The starter is located under the intake manifold, and you will have to remove the intake manifold to get to it. Do not forget to buy a intake gasket before you take it off, because they always fall apart when you take the intake manifold off.
take off the stock intake. it should pull right off....slide the new intake pipe in where the old one came off...
You take off the carburater and the intake. Clean the old gasket off and install the new one.
NO.
you take off carb or tbi and the take off all braces from intake. take out distributor and coil(you will need them later) and then take all the fastener bolts of and replace intake. put all of the things back on
