51 308 that we are currently going to grind the valves in. . . . i have a 48-52 shop manual but it is not very clear in what or how to adjust the valves. on top of the lifters there appears to be a small spring (not the valve spring) and ther does not appear to be any where to make adjustments. what do i have here ? should i take a couple pix's of the spring area or is it possible that these are hydraulic type lifters ? i guess a guy is never too old to learn. . . . . it seems that removing the valve springs is also somewhat of a problem. i have a spring compressor that may work but im not sure yet, still working on taking out the valve arrangment.

thanks in advance.

    In the Shop Manual (1948-1952), the procedure for adjusting the valves is given on page 2-7. Check pages 3-10 Figure 8, 3-28 Figure 32 and 3-38 Figure 43. Does this look like what you have?

    You have hydraulic lifters in your 308 which were standard in the 1956 AMC Hudson 308 engine. To obtain the correct information and service proceedure for these lifters you will need to obtain a 1956 engine manual or a Motors manual that covers this model year. Hydraulics were only standard as an OE item in 1956 but could be added to any (Big Six) from 1948 thru 1956.

    i thought thatmight be the case. i looked in the book at the pages and pix's referenced and that was not looking like what i had. (the manual is a poor re-print and the pix quality on half of them is un-readable) thanks for the re-assurance.

    i alwas was suspect of mexican food trying to kill ya. at least it seemed like it the next morning. hope your better this morning.

    another interesting situation came up after trying to get the final valve up and out. it was stuck. the valve guide came out with the valve. frozen on the valve shaft. CRAP ! besides probably not being able to save the guide or the valve, whatta ya all think it may have done to the block ? would the proper proceedure be to have a new guide installed or knurl a used on (on the outside) or are these a peice of cast steel ? i got a bit discouraged and just put it in the plastic bag with rust remover on it and quit for the night.

    open for suggestions for sure.

    kenneth, the 308 has not run since about 1967, not even turned over 'cept when we freed it up after draggin it home. this morning first thing, i pushed the valve right out thru the guide after an overnight soak in sylicroil (sp). we use that in our repair business on a regular basis.. anyway, the valve was only varnish stuck in the guide. the guide looks new, the valves look like new except for one that actually looks like a factory defect. i will attempt to replace the guide in the block using a custom rod with a shoulder on it for pushing it in. one new valve shsould do it, and the seats look great too after using a power wire brush on them. where does a guy find one of them old lapping tools with a suction cup on the bottom that you run like a hand operated drill. . . . a couple turns in one direction and a partial turn in reverse with lapping compound. dang, this old gal might even start. i do need to buy a headgaket however. . . $85 sounds about right as far as i can find. then we can determine if the car is worth all the other work it needs. . . like interior, complete strip down and etch primer, then whatever the lad needs or wants to do to it. he plans to use it this winter to go to college. actually im only supervising the operation, he's nearly 18 and doing it all himself, out in the dirt, next to the garage. . . quite a boy and a helll of a hudnut for sure. . .
