Random Questions

My first time taking apart a motor and trying to follow the manual. My steel pipe running under the intake manifold back to the heater core hose has a 3/16 hole drilled in it about 1/2” from the end closest to the water pump. Is this suppose to be there?  The hose and clamp we’re covering it. Second question are the water pump bolts suppose to have lock washers on them?

Hey Larry. There should be no hole in the pipe... just the hole at each end! If the hose and clamp covers it you should be find. I have seen them with the rear or front clamp broken off or rotted off, and the ends badly corroded but never a hole down the length of the pipe. I have inserted a couple of pictures of a nice specimen below for reference.
There were 11 bolts thru the water pump, spanning 4 sizes and all were flange head bolts and none had washers. Same for the entire front engine cover which has 17 bolts and spans 7 sizes when you include the water pump bolt... all were flange head bolts with no washers.  These were not serrated flange head bolts, just regular, so it wouldn't hurt to use a split or external tooth lock washer, or go back with a serrated flange head bolt, but from the factory they were just regular flange head bolts with no washer.

Thank Jason. I will probably replace the pipe since I’m going this far. You have one for sale

Larry, I have all 3 top of engine parts below cleaned and painted reduced to a very nice price of  $30 each or $75 for the lot of 3 items. Of course you get an addition 10% off as a Chapter Member. The return pipe is similar to the one I posted above... nice!  Price for it drops to $27 with discount or $67.50 for all 3.

Is that the oil fill tube on the left? Does it just pull straight out fairly easy? I have not removed it yet.

[Jason Edge]

From left to right: Oil filler tube, hot water return pipe, PCV Pipe. I use a rubber mallet and tap the tube left and right until it begins to wiggle and dislodge then remove from top cover. To install, use wood or hard plastic/rubber on top to gently tap down into front cover until it seats.
