High zinc oil for Ford F-150?, yes I paid attention for Porsche stuff, but... Options

I don't know my V-8 stuff. 1998 4.6 liter. Do these Trucks need the high Zinc oil?

I just got the truck. Basically it's my sons first vehicle. I haven't seen the crossover pipe yet. What does the replacement look like? is it different than the original?

Great first vehicle! Again, the drivetrain should last forever and most parts on those trucks are fairly cheap and easy to fix. Not super on gas, but not as bad as a big honking suburban or larger truck either.

The manifold crank problem is discussed here: http://www.agcoauto.com/content/news/p2_articleid/185

And the area that is prone to crack on the original all-plastic manifolds is at the front: (IMG:http://www.914world.com/bbs2/uploads_offsite/www.agcoauto.com-13527-1378741667.1.jpg)

Eventually the heating and cooling of the antifreeze weakens the plastic in this area and a crack develops. Not so much a question of "if" but "when." The solution is a replacement intake manifold, all of which have an aluminum crossover (which was Ford's recall solution, though the recall date has long since passed).

If the truck already has the aluminum crossover tube, that means the intake has already been replaced. Mine was like that when I bought it, but I still ended up putting another intake on it this past year. The plastic had gotten brittle under the aluminum crossover and cracked. So, basically every ten years or so they need to be replaced. Again, not a big deal and a fairly easy fix if you can devote a days worth of work.
