lifters

[mac]

Mac, I have changed lifters without pulling the heads with one of these. I can't remember if you can get them all out with this method, but I know some will come out this way.

i have a set of 440 source heads on and if i remember there isn't the room to do it.

As far as testing I don't know how to check the bleed down rate, that is why I replace them.

i will have to go through the break in process again?

Yes

ok update. here is a pic of what i am working with. the one on the left is what i took out and the one on the right is a brand new comp lifter.


a few years ago when i bought the lifters from summit which is a mopar performance piece was this number https://www.summitracing.com/parts/dcc-4006767ab/overview/

that pic does not seem to match what i have. my own fault for not catching it but it seems to be for a different application. the new lifter is https://www.summitracing.com/parts/cca-822-16/overview/make/dodge. which appears to be more correct. does this look like it makes more sense?

They do change over time as most manufacturers " improve" them. Sometimes that means a new set of pushrods. I now have three sets on the shelf because of this.

That oil groove doesn't allow much exposure to the oil gallery on the old one. What does the bottom look like Mac, can you get a pic with a reflection that would show the wear pattern?

actually it was wearing very well. you could tell it was rotating as was all of them. you nailed it with the oil galley. that was what i was hoping someone else would have noticed it. looking at other websites that may be a lifter for old big blocks like in the 1950's.
