Back on topic,
Correct me if wrong, but I don't see a filter in the parts list and have never seen one on a first rebuild. By design, filters are a maintenance part that require changing. This one would be difficult, to say the least to change. IF you do rigorous oil changes I see no problems with a filter (not getting into filter medium type) like this getting clogged. IF this was a neglected driver with many miles, this filter could potentially be a problem. Clogged with carbon deposits from ring blow by and/or oxidized oil deposits. I remove them if I find one. A baffle with no filter works, my experience. Oil vapor and lighter particulate go through the PCV, through the intake, and discharged with combustion gasses. What exactly is the problem with the original design on a well maintained engine? Or the other way of looking at this, what are we trying to fix? Does this filter increase measurable performance? Just curious on the facts/experience please.

After thinking about the original posters question and reading through the 9 pages I have come to the conclusion that if I needed a filter I would use a sintered bronze plate. I think this might be the best overall material to use. http://amespore.com/en/find-out-your-amespore-filter/bronze-plate-filters/

As far as the rivets go someone mentioned that Fastenal has the drive screws.
Does anyone know the size and or the part number?

I think they were the #8 size but dont have any more to measure. I bought a pack of three different sizes from ebay. Steel, not aluminum. Maybe 10 or 12 of each size. Maybe use drill bits to check hole size and compare to the chart posted previously.

Well shucks, the particular size I'm unable to find in the Parts Manual...
They appear to have came with the manifold with the baffle already attached from AMC... And this was from McMaster Carr 20 some years ago... Edited by PHAT69AMX - May/05/2019 at 11:48pm |

Well ChillyB sent me all three sizes and I'm sure glad he did because as I was drilling the old rivets out, the holes got bigger. As a result, the original size didn't fit anymore, but the larger of the three sizes did. So in the end, JerseyJoe, if you're prepping a used manifold then it might be better to get all three sizes just to be on the safe side..

I may have missed something during the big fight but did the OP ever take it back apart and install the baffle?
Looking everywhere for one of those, I'll pay good money if you have it and want to sell it (or anybody else that has one) |

Yes, I ground the old rivets out of the old manifold and riveted the baffle to the new manifold with the new rivets. After all the hub-bub, I didn't put any kind of filter into the baffle because it didn't have one on the old manifold i took it off of (unless it disentegrated into the engine, haha)
