Uh-Oh!

I am in the middle of building my Flathead V8 and am planning on doing away with the stock fuel pump. I wanted to plug off the guide for the pushrod. I was planning on using 5/16" cup type freeze plugs. I drove the first one down from the top and it was a somewhat tight fit. But as I drove it further down the hole it became looser the further I went. I was afraid it wasn't tight enough to withstand oil pressure. I had no recourse but drive it through the other end. Well I thought I could get it out from the cam area but I guess not.

My question is, do I have to remove the valves and cam to extract this little item? Would it cause any harm should I leave it there? It is a short block now with the crank, pistons, rods, cam & valves in.

Any help would be appreciated.

Thanks

If you want it out, yeah, you'll need to remove all that you stated, but I can't see where it would hurt anything leaving it there. Its between the rear cam bearings, there would be oil around it so no dry metal running on dry metal. The only thing it would be touching is the push rod escentric. Looking at a flatty here in the shop, thats my observation, but experianced flathead guys may come up with that being a no no.

Do you think it will eventually migrate down into the oil pan? If it gets down there it shouldn't cause any harm.

Thanks for the reply
