    Default 460 Ford valve adjust

    How can I tell if I have solid or hydraulic lifters in a 460 BBF, and what should roller rockers be set at?

    I am leaning toward hydraulic as well. Right now, most are set at 0 lash, but 3 or 4 have excessive clearance.

    If you have, or can get access to a bore scope or more likely a general inspection camera. RIDGID Micro CA25 Inspection Camera-40043 - The Home Depot
    You should be able see what they look like.

    I have several, and the one I like best came from Harbor freight. Beside clarity, check out the diameter of the viewing lens, some are much smaller than others.

    Take that orange dead blow or something and push down on top of the rocker where the push rod end is,or in other words see if you can make the lifter collapse.

    Hope to get beck on it today. Thanks for all the responses. It's been a lot of years since I messed with performance boats, so It's all coming back slowly. My mind just needs a bit of jogging, now & then.

    Take rockers,guide plates and push rods out of one cylinder. look down the head push rod hole at the top of the lifter. If it has a c-clip it is hydraulic if not it is solid. Dead blow hammer is not going to tell you dick because they are pumped-up. hydraulic lifters are a lifter in a lifter, solids are one piece and don't have the c-clip to hold the lifter together. Good luck. M

    Well, I was curious as when I checked it out it had been several days since it ran and few rockers were really loose. Turns out they had just bled down. Once I fired it up for a few seconds, they are all pretty consistent. Defiantly hydraulics. Got the pump all rebuilt and getting ready o go try it out.
    Wish us luck.

    Some solid lifters have a c clip also.

    Default Sucsess!!!

    Well, it runs good and squirts. Has a couple minor issues that won't be a big issue. Appears I did not get the bowl sealed good, as it leaks a bit water around it, and the oil dip stick loose in the block, so blows a little oil out. I think if I get a new dip stick, that will be good though.
