Oil Slinger hits timing chain

just me I'd wanna at least compare the rollmaster set to an OE set to see what is different. Yes seal quality is light years away from decades ago & many go without the seal with no leakage (usually they just inadvertently space puttin it back in). It may have some function as an oil "slinger" but I drill a .015" hole in the front of the oil gallery (& a larger hole in the cam plate) so the chain will get a mini pressurized squirt & also same (.015) in the inside plug at the rear of the dr oil gallery to oil the intergear/cam gear. Use alum 3/8 NPT pipe plugs
