How's it come off 351 V6 question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This is on the back driver side top of 351 V6 motor behind head. Its a filter of some sort, factory. Top part screws off and a filter inside, but I'm wondering how the bottom comes out of the motor. ANYBODY???? Thanks Randy

is that the original "reusable style" filter?

It's the crankcase vent filter. Just went and looked at mine, appears it just presses in to the block. Alot of folks replace it with a KN filter, I don't remember the part #, but can find it if you want.

I was just wanting to take it off to try to sell. I don't want to damage it, I have to pull the cab so once I get the cab off maybe I can get to it easier. Any ides on getting it out if its pressed in? Thanks Randy

The above posts are correct, it's a crankcase air filter. NAPA part #2718. The filter housing does press in the hole in the block, but they can be tough to remove. The PCV valves actually screw into the heads under the valve covers.
