Moncton,
I've been doing alot of searching and thinking on how I'm going to finish off my balance shaft removal. While thinking about the best solution to do the removal I thought of a way to relieve some pressure this removal causes. If you use the stock rear shaft (oil pump) when you cut it there is a oiling hole going through the center. I am going to weld this hole shut, but I was thinking couldn't you relieve some pressure by drilling a small hole 1/16" or so to start. Same with the front balance shaft, it'll be completely removed (bearing also) then a plug with a simular sized hole drilled in it will be taped and installed. After that a plate made up to block off the hole. I can't see how this would cause any problems as it'll just be dumping oil back into the bottom end and if the hole stays small enough it'll still have pressure.
I would like to see a good discussion on this like the size the holes should first start out as, pros and cons that it could cause, etc... I don't expect anyone to do this as I'll test it out myself but would like some serious feedback.

I make a stub shaft for the oil pump, and leave the other shaft in place without a belt. I've never had a higher than normal oil pressure in any engine with this method. By doing it this way I only delete 1 bearing journal.

I was reading through my post and have the front and rear reversed, I'll be editing it properly. That is what I meant is the oil pump gear shaft as the one cut and welded with a tiny hole drilled in it.
