Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?

Ok so I finally got around to watching that video. And I have a few things to say about it. My take from it may be a little different than yalls but here is my takeaway from it.
1) always use rtv or some sealant when installing new freeze plugs
2) always have the block and heads thoroughly cleaned anytime your putting an engine together even if it is a budget build and you can afford to do machine work to it! I'm so glad now that I aborted my "budget 318" build when I did because that was exactly what I had planned on doing (what they did)
3) 318s are remarkably tough!!!! That thing was through together in one day didnt have any oil pressure was dirty and nasty the cam was never properly broken in leaking fluid, too short push rods, god only knows what the clearance was in the bearings. And it still revved to 5 grand and never blew up and made 245 hp without being timed probably! To me that's pretty impressive!
I do have a couple questions I hope they will answer eventually! At the end he said that Tony figured out the oil pressure problem was due to a lifter issue. What could happen in the lifters for it to cause the op to drop like that? Did they collapse? I know that it may seem disastrous but imo builds like that is how you learn! I'm glad they did it and I'm glad I watched it! I learned alot from it. So when I finally do get around to doing my budget 318 I know exactly what not to do and what to watch for!
