guys, we want to check the valve lash on my buddys 1960 edsel that has a 292. whats the intake and exhaust valve lash ? i searched and found a couple of links that say both intake and exhaust are .019 ? is that true ? thanks leonard
if it is a stock cam, that is correct. a better way because of the wear on the valve train(assuming it is an old engine) is just tighten down on the adjuster until all clearance is gone, than back off 1/4 turn and lock it down. do this on all valves. this should give a more accurate adjustment. hope this helps
I did a lot of Yblocks and the settings I used the most was .018. Y blocks are supose to be noisey because there all solid mush room lifters. If you have a racing cam use the recomended setting.
thanks guys. .019" it is. and yes, its noisy. LOL. we just want to confirm its not any more than .019". leonard
Also make sure you are getting oil to the rockers, they were bad about pulling up. Can't tell you how many out side oil lines I have used years ago.
They were a fix for jurks that didn't keep there oil clean,was never needed if it was clean. it was kit the replace one bolt VC on each side and feed oil though inside of bolt to rockers from side of block.
I have set them at .019 on stock cam and anything other than stock I always go by what the cam maker tell you to set them at . I have also set them with the engine running then tighten down till the "tap" stops then turn back 1/4 turn . Either way is OK but I prefer the feeler gauge for setting the valves . Hope this helps .

There is no need for external oilers, this is a stupid fix in my mind, you can usually fix it right just as easy as adding one of these. If you can't there is a need for more than a patch anyway.
And it won't run right either. I tuned a Y-block for a customer recently that was set to zero-lash. Pull off a few at random, one-at-a-time, and inspect them for wear. If there is a pocket of wear in the rocker where the pushrod touches it, this will prevent proper adjustment with a feeler gauge. If they show wear, then a good machine shop can re-face them for pretty cheap. If you go for the re-face, mark them for position before you take them off, and put them back where they came from after.
