Oem roller lifters

[mikedevore]

Anyone know if the Roller lifter from a 1988 318 has the same dimension of a 5.2 Magnum roller lifter?
I understand the magnum lifter has an oiling hole in it to oil thru the pushrods & the early roller doesn't.
Is that the only difference?

I thought they were the same parts & the difference is the pushrod. Just make sure the air bleed hole points towards the valley or they get air locked.

That is a big help.
Just spoke to my buddy thats having a problem.
He installed all of them with the hole towards the outside.
The engine started & ran well, then started popping back thru the exhaust.
He started backing off the rockers & found the valves were staying open.
Air lock could be his problem.
Thanks.
