It’s 5/16 and yes I did drill out the cam bearing which had spun about 1/8” partially blocking the oil flow up to the rocker shaft. I could tell because the drill bit snagged when I hit that partially opened hole. Drilled through to the cam, spun the oil pump, oil and shavings came up the passage and out. I purged the oil passage until the oil ran clear and shavings were out. This a “what have you got to lose” fix. The alternative was to pull an otherwise good engine just to replace a cam bearing. With the engine out I would do a complete and costly overhaul and it wouldn’t run any better than it does now.
@@jaronkanorr9995 He didn't,, he drilled through the camshaft bearing to create an oil feed hole. Now,,,,, I have many MANY questions,, lol,, but I ain't gonna type them out...
I guess it's safe to assume that you didn't use that 3/8" long bit to drill that cam bearing... lol

@@Volterrific Excellent 5/16 sounds more reasonable,, it looks huge in the video..
I hope it works out
@@2packs4sure the passage is 5/16 so I used a 5/16 drill bit
Why would you drill through the camshaft
