455 Pre-oiling issue
 

Hi All,
Just found your forum!
I am trying to pre-oil after installing a new timing cover/oil pump. I am getting oil to all lifter bores and a few rockers but not all. The ones that ARE oiling are on the left head.
TIA
John

How did you make out with this problem ?

Realize it is a little,,,,,,,,,,,,,,,,,,,,late, but just checked and remembered those 455s were a powerhouse.,

Don't know if the new Buicks have the same ride quality as the older cars.
