Re: [Amc-list] 401 Oil Mods

[Frank Swygert <farna@xxxxxxx>]

I agree with Tom -- let's just keep it at "agreeing to disagree" if a concensus can't be reached and let it go. No one has to "win"!! 

As for the sixes, well, they've never had oiling issues that I know of! The only exception is the early 199/232/258 with rocker shafts. Those need a mod to one of the rocker shaft bolts to allow more oil to the shaft. This was fixed in the 74 rocker shaft engine. The V-8 is just a bit harder to get oil around in than the I-6, partially due to configuration, partially due to the different oil pump designs. That aluminum case oil pump is prone to wear over a lot of time and miles, much more than the cast iron oil pump in the six (and the GEN-1 V-8, which also doesn't seem to experience oiling problems, with a possible exception of the rocker shaft at extended high rpm -- the 66 NASCAR effort experienced broke rocker arms on several occasion, no data if they were oil ralated though).

We need the diversity, it's good for everyone, and that means
disagreement on technique. The rest of us reading this stuff
aren't listening for "who will win X argument?" but "wow these
are all interesting ideas to consider".

I wish yall'd pipe up about AMC six issues like this and not
just 8's.  While I don't go for performance like that I DO go
for longevity and I sometimes use my motors hard in the desert --
good oiling and build techniques matter!
