I've got to pull the valve guides out my 308. I suspect a difficult task. Any suggestions on the type/kind of puller would be appreciated as well as tips.

    I don't believe you use a puller, but a drift which you drive down after pulling the valve out of the guide.

    Be sure & use the proper size drift and don't get too "carried away" as if been in a long time might shatter on too hard of an initial impact.

    When replacing also make sure are put new ones in at the proper depth in the block.

    Lots of fun, LOL!

    I use a puller and pull them out through the top. Not very difficult the same tool puts the new ones in. I have seen guys make pullers.

    According to the shop manual ('52 Hudson mechanical) you're supposed to pull them, but you are saying they can be pushed through as well? Should the drift be of a softer material.?

    probably - not sure a brass one hard enough.

    I drove the guides out of a 308 awhile back with a piece of steel rod a little smaller than the bore for the guides. Had the cam and tappets already out so no problem. Dont think they will clear with the tappets in the block. Have pulled them useing allthread 5/16 threaded rod. Dont have the special factory tools.

    I used a length of stainless 5/16 threaded rod, a long connector nut and an assortment of washers to pull mine out the top and pull them back in from the bottom. Worked great. I hate banging on cold cast iron.



    I tried regular threaded rod but it wouldn't stand up to the stress.

    See I remember somewhere before Josh mentioning making this. Make a puller like Josh.

    on a bare block on a stand, i used a large piece - roughly 1 to 1 1/8" of bright steel bar to really give the guides a shock and break the bond of 50 odd years of being up close and personal with the block. once they are on the move oil helps!in car, i'd be making a puller of some sort, but make sure its strong- ive bent 3/16" plate into the port a bit rather than move the guide.

    We Use A Two Diameter Punch If Fits Down The Guide About 3 Inches, Then Has A Shoulder To Cover Top Of Guide, Drives Them Out The Bottom. You Do Get Some Breakage Occasionally Of Guid, But They Come Out, Bill Albright

    Bill or Uncle Josh-

    Can this be done with the engine in the car? (52 Commodore 8) We have the valves out and the springs out, but the tappets are still in. We need to replace the exhaust ones and one or two of the intake guides...
