Oil pump

I have learned about the bolt that acts as a set screw to keep the oil pump from dropping down when the oil pan is dropped. On my engine there is a tube feeding the oil filter. How do I deal with the oil pump if I drop the pan?

Temporarily disconnect the oil filter feed line's elbow and use the oil pump bolt to hold the pump in place while you install the oil pan. When the pan has been bolted up, remove the set bolt and reconnect the oil filter line. You may have to loosen both fittings on the line to remove it.

By the way, don't use a regular bolt screwed into the side of the block to hold the oil pump! Those are pipe threads in the block and a bolt screwed in will damage the threads. Use the special little holder available from vendors. There are at least two different styles, but they do the same thing.

When the engine is in the car and you remove the oil pan, it is a good thing when the oil pump comes down inside the pan. The pump retaining screw is a must use when installing the oil pump and pan.
Many years ago, I had an engine rebuilt by a shop, and the person who assembled the engine tied the pump into place with cotton clothesline cord. The cord was left in the engine. The cord disintegrated, it clogged the pump screen and the engine starved for oil while away on a cruise.

 
I agree on allowing the oil pump to drop down with the oil pan during removal. Depending upon how the pan gaskets had been secured - with Gorilla glue or something equally binding - the pan can be a bear to break loose from the engine block, often requiring rocking the pan side to side. It's possible if the pan lets go all of a sudden during one of these movements to break the oil pump housing. You needn't ask how I know this (experience gained in 1968!). Use the pump retainer tool when you RE-INSTALL the oil pan to keep the pump from dropping out of the engine, as I wrote in Post #2.

Thanks for the feedback. I know my engine is a rebuild from sometime in the distant past, and have no reason to drop the pan other than to see what is there. I really--REALLY- appreciate the opportunity to learn from others' experiences.
 
Another trick to hold the oil pump in place using tie wraps, once the bolts are in place but leaving a gap, then cut the tie wraps and pull them out.
