pflaming Posted June 10, 2010 Report Share Posted June 10, 2010 (edited) Was 'surfing' and noticed on a recent thread', in a picture showing the crankshaft of his engine, an oil pipe that 'snakes' its way from one side of the block to the other between two rod bearings. I took the oil pan off of two engines, on my parts shelf is this tube. It is about 1/2 inch in diameter. Now I am worried, did I forget this tube on my 'rebuild' or is this from the other engine which I traded to a forum member? Question(s): (1) what does that tube do and (2) if I am running at 45# oil pressure does that mean that tube is in? To check, the work needed is obvious: drain the oil and drop the pan far enough to look in, OUCH!. Should have taken another picture. Us novices just don't know enough and its so easy to get ahead of the program. Suggestions welcomed.

Reg Evans Posted June 10, 2010 Report Share Posted June 10, 2010 If you mean the oil pickup tube with the screen thingy on it I think you would know by now if you had left that off. Quote Link to comment Share on other sites More sharing options...
Young Ed Posted June 10, 2010 Report Share Posted June 10, 2010 I think he's talking about the oil crossover tube. And I believe you wouldn't have oil pressure if it was left out. Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted June 10, 2010 Report Share Posted June 10, 2010 There are two pipes in your oil pan. One is the pick up tube with the screen as Reg mentioned. The other is the crossover pipe from the oil pump to the oil galley. Quote Link to comment Share on other sites More sharing options...
Dave72dt Posted June 10, 2010 Report Share Posted June 10, 2010 (edited) They must both be in there. As you can see from Don C's photo, if the oil pickup tube wasn't there , it wouldn't pick up any oil. If the crossover tube wasn't there, the oil would simply dump back to sump and you'd have no oil pressure. Oil pressure is merely a measurement of the force required to push the oil past it's most restrictive opening. There's no restriction if the crossover tube is out.

pflaming Posted June 10, 2010 Author Report Share Posted June 10, 2010 Don's picture told the entire story. I studied how the engine works and you confirmed my search that without that pipe no oil pressure. It appears that crossover tube carries the oil from the pump to the oil 'routes' in the block. So one less worry. Thanks for the reponses. Now I am trying to get the old bolts out of the fender mount brace, the one that has the rivits on the outside, the bolts twisted off when I removed the dog house. Man, nothing is easy on this project. Quote Link to comment Share on other sites More sharing options...

Here is my silly question Paul, did you inform the member who bought your engine that you still have his pipe:D:D:D Quote Link to comment Share on other sites More sharing options...
pflaming Posted June 12, 2010 Author Report Share Posted June 12, 2010 Frankie, no! I gave him a good discount so I figured I'd keep back a few parts. Boy, you sure know how to hurt a guy!!!! Frankie and I jest with each other, in the late 60's and 70's I lived in Omaha so . . . Frainkie's OK, even though he is a Texas Aggie fan living in Nebraska, but he's smart and will eventually understand. Quote Link to comment Share on other sites More sharing options...
