ed, don't want you to fell short changed. if the block passages from cam to
rocker pedestal are clean, the rocker shaft passage is clear and the clearance
between the cam and the block is correct, the oiler is not needed on a street
aplication. the cam acts as an oil pump. if the clearance between shaft and
block is too great, there will not be sufficient pressure to move the oil up to
the rocker. along with this, the oil passages in the block can become
restricted with dirt, etc.the only true cure is to have the block boiled which
wil clean all passages and destroys even metal particels - see comment on
cleaning oil coolers - then have clearances checked and good careful
reassembley. we do some things to the spit engines on rebuild such as pinning
the thrust washers and other goodies. the external oil line will work in a race
engine where you need to be assured of keeping the valve train well lubed.
external oilers have been known to contribute to excess oil consumption. ted
