Anyone ever drill the stock lifter tray for better oiling...? I saw on HorsePower TV (go ahead, call me a fuckstick now for asking this question) that they drilled the brown plastic lifter tray on the sides with a 1/2" drill bit to get the oil out of the tray (away from the lifter??)...they said it helped with oiling....
I never heard of this and the only reason I am asking is that Wheel-2-Wheel was basically supplying the parts and machine work on this build up, so I thought it might be worthwhile...
Anyone ever done this or heard of this...

I saw it as well, the only issue that I had with how he did it was the 1/2 inch holes. I think that smaller holes would help the oil drain without significantly reducing the structural integrity of the lifter tray.

I would not want those holes in my lifter trays! Oil is supposed to be in there to properly lubricate the lifter riding up and down on the cam lobes. The slight increase in oil getting back to the pan faster is not worth the risk of oil starving a lifter. LS1's have been living happily since 1997 w/o these holes. Leave a good design alone. IMO

There was a thread on drilling the lifter guides about a week ago. That thread has pictures also. The idea is that the lifter guides fill up with oil that could be used by the engine, so by drilling them you keep the oil down in the pan. I think this is a good idea, but not half inch holes. Those lifter guides are on the weak side already, ask me how I know! The other way do it is not drill the guides, but just add more oil to the crankcase. I run a full six quarts in mine.

Here is the tread I started. THIS IS A W2W INOVATION.

The holes go to the ex side. They go on the low side when installing.

as said earlier, it is in the Will Handzel book.
the point is oil control, drilling out the lower face of the lifter retainer trays above each lifter is ok, one 1/2" hole is better than two, or more little holes
because of stress.
in a stock production engine, having oil pooling here is acceptable, but on a high-rpm engine, it will cost power by causing the oil to foam and get hot.
adding more oil than is appropriate for the application is not a good idea, because of drag on the rotating assembly, and could cause more to pool up in the rocker vally, and lifter trays.

Adding more oil than is appropriate will cause interference with the crank rotation? Any idea how much oil the pan can hold before the oil gets near the crank windage tray?
