I have 2 external oiling kits and some directions and think as soon as weather gets warmer and my back better- I will attempt it.
My 56 has a 272 and the pass side valve train seems to run dry or needs valves adjusted or ? I have never been an engine dude,and concentrate most of my restorations on paint and auto-body.
I would appreciate any dos and don'ts and when I am ready will git-r-done

Problem is plugged oil gallery caused by running non detergent oil too long. Best to clean out the galleries and run a good mulit grade detergent oil with adequate ZDDP adative for the cam.

Thanks guys--I only ran the truck for 15 miles since I changed oil to DELO and it had 21,000 miles and before had 30 weight non det. oil most all it's life--but is super clean....I spoke to original owner and he said it was rebuilt-?? and it ran fine---now I drive it around alittle and spray the valve train with oil and it stops....Tom must be correct. I will write when I am ready.....thanks !.......Bill
The term "rebuilt" can mean many different things. Lots of folks think that new rings and rod bearings is a rebuild. Even when they take the time to pull the engine and put in cam bearings, the block and heads are often rinsed with degreaser and not boiled out and boiling does not always break thru the gunk - need to run a brush.

the problem with Y-blocks is the cam bearing would turn cuyying off oil supply to top end and other than new cam bearings an external oiler was the only way to supply oil to top end
Some people use to feel the external kits robbed oil from the main/rod bearings. I would suspect it would if the oilers were allowed to pump an excess amount of oil to the rockers. This can occur if the bores in the rockers are worn oversize and oilers are allowed to pump an excess amount of oil to lub the push rod contacts despite the loss of oil on the shafts/rockers. JKust a thought
Some of the oiler kits did not have a regulating valve to control topside oil.
Without regulation you could possibly flood the topside and starve the crankshaft. The best way to adjust the oiler kits is to run the engine with the covers off and just adjust the valve till all the rockers are getting oil, just enough to provide lube but not too much so as not too flood the top end.
Thanks and I will be installing it soon......It is snowing again!--I can't get this big truck in my barn this year--so it will be an outside job.....Bill
