Timing set woes

If we are speaking of the OE bolt in the top pass cam plate hole, that bolt has an 1/8 hole in it. It is just a drip hole. Some eng had that & some had the angled drip tray and reportedly some had both. I drill a .015" hole in the freeze plug in the front of the pass horizontle oil gallery then a ~1/2" hole in the cam plate in front of it for room so it can squirt out under pressure to the chain. that bit is the size of a strand of hair & go REAL slow & bathe the bit with oil. I also drill that same hole in a speedway motors 3/8 NPT alum pipe plug to go in the rear of the dr horizontle oil gallery to lube the intergear. when you preoil you will see the squirt & (likely) be convinced of its bennie.
