i've pretty much got my block teardown project complete, all but one bad exhaust manifold and this. how does the cylinder block oil pipe (laying in the bottom of the intake chamber) come out? i found the plug on the front of the block, and it came out easily. does this oil pipe just slide out or does it require a little coaxing from the other end somewhere?
thanks
 
Those oil passage ways were never designed to be removed. You clean then the same way you would a sludge trap in the crankshaft. It the tube was not secure it its bore it could rotate and shut of the flow of oil to the cam and main beaings that it supplies plus there would likely be a leak in those areas. Just find or fabricate a tool to clean the passage way out.

They will usually be pretty well cleaned out when the block is boiled out in a hot tank.

Sludge rarely builds in the valley pipe due to high oil flow. Once you get both plugs out you can peer into it and check.

thanks to all; after i posted this question, i looked a little closer myself and saw where there's really no way, nor need to remove it. but....upon that inspecion, what about the sleeve that's down in the fuel pump push rod cylinder, that looks like it may be removable, and if so, and i mangle it up, are there replacements?
thanks
 
My local machine shop had reason to remove one of those oil galley tubes a year ago. The block had set with water in the galley and the tube had rusted....aside from that the block was fine. I had a bum block that was going to be scrapped. I let him have it and he found a way to remove the tube from both. He removed the front plug, then tapped more threads into the front of the tube. Using a slide hammer he adapted for the purpose, he was able to coax the tubes out of each block. Then he placed the replacement tube in his good block. He's done this twice, so apparently it works. I'll have to ask him for more details.
