This is very interesting.
Ok, so after further investigation, this is what i gather
-
oil travels through the
oil galley for the lifters, then up through the small hole to the deck of the block where it meets a channel in the cylinder head. It then travels about a 1/4 of an inch over to the cylinder head stud hole where it makes it way up around the stud to a hole in the cylinder head. From there it travels out to around the second stud for the shaft rockers and up the stud to a hole in the shaft. From there it works its way out to each individual rocker arm.
This seems a like a very arse backwards way of getting
oil to the valvetrain, but what do i know.
Thanks again guys!
Im still looking at these PBM hydraulic roller lifters and trying to figure out how the oil enters them.
