Re: 59 AB engine rebuild
I believe you do have the late rotator valves fitted. This is a definite plus when it comes to dis-assembly. The conventional way of pulling the guides down, pulling out the horseshoe clip and then withdrawing the whole assembly as a unit is probably best bypassed in this case because the guides look like they will not move easily enough for that to happen.
Get your valve tool behind the small retainer at the end of the valve, lift it (you might need to tap the valve head gently to break the taper) and the collets should come out.
Then withdraw the valve, tap the guide down a little way(using a long socket or similar), remove the horseshoe clip and pull the spring and guide up and out of the block.
Piece of cake.
Mart.
