Re: Rockershaft Auxillary Oil Feed..Is it necessar
Ned,
I don't think that it improves "oil pressure" up top as much as adds a greater volume of oil to the top of the engine. But as Andy and others have pointed out, "at what other cost"?
Again, I saw no difference in oil pressure with the addition of the line, but man did I see oil in my intake manifold. Remember, I had an aluminum cover with no baffle at the time.
If someone has low oil pressure due to worn main bearings, blocked galleys or simply a worn oil pump, this will not help, because something else will starve to supply more oil to the top.
If I do go to new roller rockers when I swap out my head, I'll drop the oil pan and install a brand new oil pump, which is safely tucked away in my new spares bin.
