    Well the reason my #1 cylinder is dead is that the valve spring on the intake is loose and 1 of the pieces that are on the top and bottom of spring(dont know what they are called tappets maybe)the one on the bottom is off (this is a L head by the way) was it just never put on or do they come off every now and then. My Question is...is it hard to fix? I have the head bolts loose ready to come off and the manifolds off and the valve cover off. Dont see any thing in my book that say :flag: s how to remove the spring and put it back together. I'mm looking to my experts out there to give me some guidence.
    I pulled the head off and lifted up the valve and the spring came right out. Will it be difficult to put a new spring in? The piece that came out fits right into the spring it looks like a hat its dinged up a bit is this a tappet?

    not clear to me
    the two keepers that fit into a groove in the valve, that keep the retainer compressed on top of the spring, they are missing?
    tappets=lifters (more or less)

    The valve groove has nothing in it I can pull the valve right up out of the block.the only pieces that slid off the valve was the broken spring and that hat looking thing
    that sits into the bottom of the spring.(this piece was off laying by the oil gallery on its own) I think that hat thing keeps the tention on the spring and when the valve goes up more tention is on the spring to open valve.

    The keepers or locks just fell off your retainer, all you need is a valve spring compressor and a new set of locks but check the valve to make sure its not damaged.
    However those old keepers are somwhere in the mess, you need to drain the oil and look hard for them before putting it back together and driving this thing very far.

    Will I have enough room to compress and install the spring with engine in. And is there any websites that have pics of this. I'm looking for a great book (good dont cut it) What do you guys recomend for lottsa pics and how tos? I am missing the locks.

    So do I just compress the spring slide on retainer then the locks and uncompress spring and I'm good to go. I found a pic on the web but I donot know how to get it in message.

    If the spring broke, that could explain how the locks and retainer came off. I would look very carefully at the valve where the locks go and ensure that groove is clean. I would consider myself lucky if some part of the valvetrain came loose and didn't ruin anything...

    Hard to say what those bits of metal could do if they got jammed in the recirpcating mass in the bottom end. I would look really hard to find those valve keepers, both in the lifter valley and in the bottom of the oil pan. It is deceiving just how deep that lifter valley is, and the amount of crud that can collect in there! If you get lucky, the keepers will be in there, and you'll find both pieces in un-mangled form.

    I'd sure want to know where those little buggers ended up!

    I would also look at the combustion chamber in the head. With no spring tension on that valve it very well may have bounced off of the cam lobe and into the head a time or two thousand. Would also check the lobe too.

    You could probably do this repair with the head on.

    First, you will need a valve spring compressor. Snap on makes them under the name Blue Point. I don't have the number off hand, but you might be able to call snap on and tell them you need a valve spring compressor for a FLATHEAD engine.

    If you want to know what one looks like, look on ebay completed listings for willys valve spring compressor. One just sold for 85.00 which is amazing because a new one from snap on is around 50.00

    I think it is something, something 49A or 49B as the blue point part number.

    You will need a valve rotator and two locks and I'd throw in a spring for good measure. Note that if you look at the spring the coils at one end are closer than at the other end. The 'close' end goes up towards the head, and the 'open' end goes down towards the tappet.

    This is really important to get right if you ever want to get this apart again .

    When re-assembling, I cannot emphasize enough the safety aspect. Use eye protection, and a small screwdriver and needle nose to install the keepers. Put a little grease on them and they will stick to the valve stem.

    Under no circumstances stick your finger in there for any reason whilst the spring is under compression.

    If one of the keepers falls off, use a telescoping magnet to retrieve it.

    This is really pretty easy to do, but the safety aspect is very important.

    You really want to use all ten fingers and both eyes for the rest of your life.

    All the parts are available from turner 4wd 1-800-the -jeep.

    After assembly, adjust the valve.

    I bet thats why the #1 and #2 cylinders have half moon indentations in it? (could it be?) they probably made it up there somehow and got blown out exaust after they were chewed up. the #1 cylinder has about 10 of these indentations and the #2 cylinder has just a couple. What do ya think?

    Sorry to bump such a old thread, but I found this thread in a search for a valve spring compressor.and thought I had found jack pot on a picture of one, but it looks as it has been lost.(that the reason the "log in" thing pops up when you click on this thread......

    any how, dose any one have a picture of the vavle spring compressor. and or know where to get one.

    gave it hell trying to make my own out of a c-clamp, ohh so close, then it would slip out on me.

    anyhow glad I foun this thread. about the valve spring its self, the tighter progesive end to the top.Im wondering if that might have been what was causing my cussing lol...

    by the way Im working on a 226 flathead in a 62 willys truck
