Re: [BaadAssGremlins] re: amc six popping thru carburetor

I recently had a Comp Cams Hyd Flat Tappet cam lose a lobe. When I got the car, there weren't that many miles on the 401 motor... just over 10K. The original owner was using Kendall. Of course, NO ZDDP was used. Ever. Just some cam lube for the initial install. So of course I was expecting it to fail. The original owner just didn't know any better. I won't get into his IQ or personal hygiene, but I understood why...

I went to Comp Cams and ordered a new one treated via their Nitriding process. Cost appx an extra $100. Worth it in the end. Anyone replacing a (flat tappet) cam these days should strongly consider this. Next time, I'll do a Hyd Roller.

Just came back from mechainc's place in another 100 degree heat day, it is camshaft, #1 &
#2 cylinders it appears, just flat. Ironically I drove the car over there yesterday and
didn't have that popping noise.Still had a noticeable miss, but the loud pop was gone,
replaced with 'softer' popping thru carb. Someone on amc-list I believe mentioned 1982s
had some cam issues so looks like engine will come out, valve job done and hope to be back
on road in it in few weeks. Thanks to all who replied also,

=====================================

I would start with a compression test.... super easy on the AMC 6's. ?If the pop is
affiliated with one cylinder it is more likely valvetrain, lifter or cam related.
If one cylinder PSI is way off... pop off the valve cover and spin it over to see if the
valvetrain on that cylinder are acting differently from the rest. ?If you find something
shout back at us and we'll get 'er figured out! ?
Have a great week,?
