| Valve Problem |

| Hi Guys, got a problem. First what I have- '63 390 with about 50-60,000 on the rebuild.I got the truck when my Dad passed away in '92. Driving it home it had a miss, did a comp test and determined it had a burnt valve, so had the heads done. New ex valves and hardened seats, was told intakes ok, new springs, cam and lifters ( mild Isky hyd 202/208 .492/.488 ), new p/rods and adj rockers and shafts. Now for the problem- I've had a mild ticking problem for awhile, but since this is a weekend driver at most, just kind of ignored it. Postings on this and other boards made me think it was typical of these motors to tick some. Anyways I found the one that was ticking, idled it way down, and started backing off on the adj nut to see if it would get louder. Something didn't look right so I shut it off. The top of the valve was wore allmost down to the keeper, with a dished look to it. I also noticed some p/rods spun like crazy, and some barely turned at all ( while idleing). Also with all this oil mod talk on the FE forums, I got to looking at the rocker shafts to see if I had an excess of oil, and noticed the stand that has the oil passage (3rd one back) had oil coming around those rockers but very little towards the front of the shaft. Reguarding the spinning/slow spinning p/rods, does this indicate a cam/lifter problem also? Any advice you Guys can offer as why this might of happened/ what to look out for when it goes back together agin would be GREATLY appreciated. Many Thanks,Al |
