    Shallow socket and a universal on a 3/8 or 1/4" drive.

    The lifters will compress if not completely full of oil. If full of oil they won't compress. Not by hand any how. They suck to take apart and clean its a long and frustrating job. At least it was for me doing 1 at a time to mix nothing up.

    I'm wondering if I need to take them apart at all. If I'm looking for a bad one, would it be obvious from the outside of the lifter? Maybe?

    If you let the lifter stand top down for awhile to let some oil out the plunger will compress. What you have look different than the ones in the 152 I did. They had a spring under the plunger. In the repair manual it says some do and some don’t. It looks like the area you are talking about is part of the cast.
    Do you have a repair manual?

    I was expecting a spring under the plunger. I don't have a repair manual, I'm not 100% sure what the engine is out of. It's not original.

    If one is defective it wont be obvious by looking at it unless you have a serious problem, like a bad cam shaft. If you don’t want to clean them I’d “think” that if it wont compress with oil in it and will compress after the oil drains its probably ok. The manual tells how to do a simple test after they have been cleaned. (I’ll send a PM)

    I was just sitting here wondering, when I take the clip out of the lifter, what's holding the whole thing together? Shouldn't it come shooting apart? Spring tension, and pumped full oil, it just seems like it wouldn't be hard to take apart, unless it's just gummed up and stuck. I'm "assuming" there's a spring under the part still in the lifter housing.

    I think that one is the type without a spring.
    You may get more info by posting a lifter question in the general forum.
    Here’s an internet pic.

    I remember mine looking like the bottom one. Yours are like the top one. Maybe the wrong type were put in that engine? Is there a part number on it? Maybe take another one apart and see if it’s the same.

    Hmm, I guess I was assuming, again! that they all had springs, unless it was solid, then it was just, solid. Could be the wrong ones in the engine I suppose.

    I got the brake booster out if the way so I could get to the rest of the lifters. Found 1 that is slightly dished, and 2 with scratches. I know I should replace the cam, lifters, springs, etc. but I think I'm going to try just replacing those lifters. I keep reading about you guys replacing a dished lifter and having it run forever with no problems, so....

    Common practice is to replace them all at once but I only replaced the ones needed 15 years ago and the engine runs fine still.
    The scratches are more concerning than the cupping. A sure sign that that area is not getting proper oil flow.
    Does the rocker shaft look ok (especially the rocker for that lifter)?

    Seems like the rockers looked ok. I'll look closer, but I don't recall anything jumping out at me.

    I’ve not used that one. I’m sure its fine. I use lubriplate.
    How many need to be replaced on that side? While you have it apart I’d change any that cant be taken apart, cleaned and deemed functional. Hopefully it takes care of the problem.

    Once I found the dished one I figured I would just replace it and the couple scratched ones, since I'm not 100% sure it'll actually work without the cam totally going flat or something, and trying to keep the budget down.

    Totally get working on a budget, but if you don’t replace all that are suspect and it still taps you wont be sure its not still a lifter. In the pics I sent you there is a simple test to rule out any bad ones but requires the lifter to be taken apart and cleaned. Any that cant be disassembled would have to be suspect.

    Dangit! Yeah, you're right. I'll experiment with one of the scratched ones Tonite.
