My 29 Special Coupe I find has had a modification in the oil supply gallery where the valve springs are located. I decided to inspect the bottom end of the engine and oil gallery for any gunk build up. Both appear normal for the driving I have done over the years which is not much driving. But looking at the front of the oil gallery I find a hole that lets oil flow from the gallery to the timing gear area. This hole has been modified. During an overhaul in the past someone lowered the bottom of the hole by cutting away some material. This will lower the level of the oil in this front sump. By running a straight edge along the top of the front dam it looks like the bottom of this hole is 0.2 inches lower than that straight edge.

My question is, why would someone make such a modification and isn't that mod cutting down on the amount of oil flowing to the other two oil bays.

I have a picture of this but don't know how to send it being a new member.

I hope I explained this well enough.

Thanks guys.
