: Doc - Now I have several questions. The cam

: Drill cam or Groove the bearing? If drilling

: anything to go by), send the cam back to
: Hughes (The so called Mopar experts), or
: have a machine shop do it? To groove the
: rear bearing - Again I don't have anything

: be removed. If done with bearing in engine
: what about the possibility of getting metal

Sense you don't want to tear down the motor, and the cam is already out. Why not put a grove in the Cam bearing surface. sounds crazy, but whats the difference? Don't know how hard a Cam is to Drill, but if it's hard stuff, grinding a groove would be easier.. it's not like a crank where you're worried about torsional strength, especially considering its the rear cam bearing. You are reducing the bearing area, but the same would be true if you grooved the bearing in the block. And this way you can be sure you got all the debris off before reassembly. Just make sure there are no burs, and the rest of the bearing surface is clean and unharmed.. My two cents.. Matt- mhaskell@reliant.com

Your machine shop should be able to drill the cam, OR just send it back to Hughes - they messed up. This is by far the easiest option. Hughes should pay for shipping or machining since it is totally their fault. Lou

I may as well cover the 3rd option, groove the rear cam bearing. Use the cam or other suitable "driver" to pop-out the rear cam plug. It is best to tape-over the oil feed holes and install the cam a little less then 1/2 way into the rear cam bearing. Use a sharp, "V" shaped tool to cut the groove into the bearing surface, using the cam's rear face as a "fence" or guide. You need to connect the two oil feed holes with one groove, no need to go all the way around the bearing, just do the half that is easy to reach. stop a little short of the holes at first, do your major cutting and blow-out all the chips before removing the cam then do the final connection into the two holes. Put some grease around the area and onto the tool to catch any chips. DD
