Block cleaned




Intake cleaned


Intake installed


The rubber gasket kept bulging out so I just used RTV after two complete tries. The rear one worked and I did trim them per the directions.



Look what came out of the intake when I flipped it

While you have the manifold off, check to be sure there's a tin pan on the bottom of it, it should have been transferred over from the stock manifold.

I FORGOT!!!!!!!!!!!!!

I knew there was something, but couldn't remember.

Is this a problem Bob?

There's no pan there. It would mount on the holes you can see in pic #3. Notice also in the top left in the pic that you can see the bottom of the PCV valve. The pan is a baffle so oil splash can't get to the PCV and get sucked into the intake. Some get away without it, some notice oil loss. It all depends on the engine, where is splashes oil, and how much blow-by there is at the rings. Since you've mounted the intake, try it and see if you have any oil consumption. If there is, you can always pull it and attach the pan.

Thanks Bib, we will see and if so then I can pull one off an old intake, lets hope everything works out.

Jim, there is another remedy if you do suck oil through your pcv. They make a oil filler tube cap with a pcv built into it. Just block of the old one and put on this cap on your oil filler tube which is 10" off the manifold.
