I'm in the middle of replacing the intake manifold gasket on my '86 bronco. Never done one before. I got everything out of the way, labeled all the stinking hoses, removed the manifold, pluged up all the orafaces, and wire wheeled the crap out of it.My ? is is there anything I need to know or watch out for before I put it back on? What kind of gasket material is recomended? Where...Kragen or Napa?
Also Is it normal to have some oil in the space between the manifold and the top of the block around the pushrods? Whats with the little pan attached to the bottom of the manifold?

Would the performer 289 intake and carb off my 69 bronco 302 bolt right up? Not that I would but I'd like to know.

Gaskets can be bought about anywhere so either of your choices good>

Use Silicone instead of end rubber pieces is a good plan (RTV)

Yes oil there is normal

No the 289 has a differant intake than a 351

NoRM

tanx Norm

Also put a little RTV around the water ports.

A couple of things to watch out for when re-installing your manifold:

* Be sure that the rear gasket doesn't slip out when you set the manifold in place. They tend to slip back and leak like a sob. I use RTV instead of the gasket.

* Be sure to add a bead of RTV to the area where side gaskets meet the front and rear gaskets. These areas tend to leak if you don't.

Good luck!

First thing first get a lot of :beer: 10 friend that know nothing about viechles who think they know it all :rolleyes: and that ther master techs. Next don't be afaid not to lessen to any of them and use lots of (red) hi temp RTV in the corners use copper seal on the intake gasgets and yes use the rubber put lots of RTV on them and make sure they dont slip they have little tabs that set the corners in place next grab sawzall chop fenders OPPSs dazing off remember to tighten form the middle out at about 35 FTLBS of tquore. next listen to beer drinking buddies on how much they helped and how screwed you would be without them.


:beer:GoodLuck :smokin:

Think its all about covered.. toss those rubber gaskets for the front and rear of the block in the trash.. set down a bead of silicone instead. The 'pan' thing under the intake is an oil shield.. it helps keep the intake cool (relatively speaking). Oil in the valley is totally normal.. and.. finally.. 302's and 351's have different deck heights, intakes are not interchangeable :)

Thank you drive through.
