I've just realized that I'd installed my intake manifold without the splash shield because it's still riveted to the old manifold I took off. Is it vital that this shield be installed? I drive my cars maybe less than 200 miles per year. I was thinking that driving it only to shows once or twice a year won't affect anything? The car is a 1971 360 ci.

Watch where your PCV routes to your air cleaner. If it is wet with oil then you need a baffle. You need a baffle regardless, just a matter of what you personally are OK with given the low usage your engine will experience.

You can also install a PVC line oil separator and my suggestion would be to put the return on the oil fill tube (easiest, most convenient, cheapest part to replace at a later date).
There are other units that are cheaper, above is just an example of what I'm referring to.

The metal intake pan gasket isn't that terribly expensive. Pull the intake manifold and transfer the PCV baffle to the bottom of the aluminum intake and be done with it.

Try it out. I never put the baffle on mine and have only ever pulled oil after a full 1/4 mile pass. Cruising, not a drop. Same for my Buddy's Gremlin. He daily drove it, drove it 1500+ mile round trip to race with no issues.
If you end up pulling oil, I'd use what Trader mentioned. Anyhow, 200 miles a year is really nothing to sweat.

Rick Jones did this to the underside of my Eddy Performer intake for me... he does something similar to all the intakes he works on...
He also did this to modify the EGR system as well... |

Is that a red Scotch Brite pad? With all of those loosely-adhered chunks of silicon carbide abrasive in a nylon mesh?

Yes it is. He's probably built over 100 AMC engines... so I'm good with it... and I am sure he will chime in if he sees this post. Edit: See this link for more info... some others had the same objection.. but others verified that it does indeed work fine... http://theamcforum.com/forum/pcv-oil-burning-u-may-be-all-wrong_topic21370.html
