New to the board. I can't seem to get the oil bypass out of my 331 Hemi. It's really tight. I've bent 2- 1/4" steel rods so far and I don't think it budged. I read the article on "Rebuilding the Early Hemi" which is how I was trying to remove it. Any tips on getting this thing out? I don't want to damage the block.
Thanks, Ed

A little carb cleaner, to desolve the varnish, often works wonders.

Something sounds 'fishy' here....Is the block on a stand? can you see the top half of the cage? There is nothing to hold the cage in place other than the bottom half with an o-ring. If you need to save the stock parts then install the main cap loosely before you put it in a hot tank....or put 'something' just over the edge of the hole so it does not fall out into the tank and be lost forever.

He checked with the guys over at Hot Heads and found that some of the earlier 1st Gen. hemis had a solid plug that made the system a full flow system, and his is most likely one of them. The plug didn't need to be removed.

Re: 54 331 Hemi Oil Bypass Removal
That was going to be my suggestion. Take the rear main off and see if there is even a bypass in it. I finished a 331 marine engine a while back and it did not have a bypass. Is your block a marine version or just an early 331 as another reply suggested? I feel that is the answer to your problem. Since the passages are a bit different than other hemis , be sure and clean all these passages as if your motor's life depends on it, which it does. Good luck, Buddy
