There is no easy way to clean out the oil gallery. The fact you have
oil pressure to the gallery (oil sender just below and feeds off of)
still makes me think the lifters, pushrods, and rockers are not
passing the oil. If the oil gallery were plugged, the engine would be
starving the hydraulic lifters and you would certainly be hearing
that.
The lifters supply the oil to the rockers via the pushrods. I would
start looking at the rocker cups (pushrod hole) and pushrods for
scratchy marks and deformed pushrod ends also with scratchy marks. If
all looks polished and ****ney then pull the lifters. If you go and
replace the lifters, buy new push rods and very carefully inspect the
rockers, not only for wear in the pivots but also in the pushrod
seats. If the rockers are not getting oil, they and the pushrods
will be scratched and worn.
After all that, I went out to the shop to look at the oiling system
for the 2.5. in the Helm's manual at 2 in the morning. From the
sump, to the oil pump, then the filter, then the oil gallery, then it
splits off to the cam and crank. Off of the cam it goes someplace
less that clear. The lifters are right on the oil gallery and should
be getting a full load of oil.
