Missing intake manifold baffle

Yanked my intake to put a Performer on it and found that it was missing the baffle. It was using the pan valley gasket without any PVC and it didn't seal well. Have a listing under parts wanted for a baffle. Looks as if my engine sucked oil into the intake runners. I'm not going to yank my heads to clean up the valves. Gas additaves are the only thing I'll do.

If you buy a Felpro gasket, the baffle is part of the manifold-to-head gaskets.

No, that is just the valley pan gasket, there is also a baffle that is riveted to the bottom of the intake to prevent any oil being sucked up by the PCV valve. Granted, the valley pan does keep most if not all the oil away from the valve.

Correct, it was missing off the manifold. I just don't know why it was removed. Hope someone will sell me one.

Hmmm I thought it was a heat shield to keep from frying oil on the crossover. I don't use it with the Edelbrock.

Jeep calls it a "heat shield", but some call it an oil baffle. I've usually heard that it's to keep oil from being sucked out of the PCV valve. It has some louvers in the rear narrow section around the PCV opening. On my last Edelbrock I cut most of it off for fitment purposes due to a valley oiler pipe that was in the way. I just kept the louvered part around the PCV port. Haven't had any problems.

Our Cherk dosen't have one at all on its rebuild with a Performer. There must be some kind of good reason for it to be there and I would normally use one. I've noticed a burnt oil patina on the crossover areas, even with the shields on several OEM intakes and a used Edelbrock. Interesting it is just in that small area under the carb where the crossover and EGR castings are, and where the main part of the shield covers.
