Roller cam/lifter problem

The solution to this persons problem would be to tube the lifter bores (~ $300). When I ran a solid roller in my stroker I had solid bodied lifters (comp 828-16's if I recall correctly)...they don't have this issue because they don't have an oil band like those.

Not sure of this person's situation, but if it was a big cam (lots of lobe lift) it can cause this. Another solution to this would be get a cam with a smaller base circle.

Idk, I never ran a hydro roller, only solid roller. Only way to find out would be to test fit the parts and see if you have an issue.
