Oil pan differences

[fins2nv]

I am trying to clean up some oil leaks and in the process have done a lot of searching for information. I have a'30 coupe and I haven't been able to find information about my oil pan. I also have the Les Andrews book. Every pan I see is solid, with just a drain plug. My pan has a plate with six small bolts and one large one in the center. I am guessing it has something to do with the oil pump. Anyway, it is leaking oil around this plate. What do I have and is this an easy leak to fix? Any help would be appreciated.

You have an early oil pan.

If it is just leaking from around the plate, replace the gasket and bolt it back on. The gaskets are readily available, or if you are handy, you can make one. The Paper one one my coupe drooled after about a year, so I made one out of sheet cork material and sealed the bolt threads as well.

Try tighting the six bolts and see if leak stops.Plate is for cleaning out oil pan
Before removing plate to replace gasket you should hold oil pump in place
by inserting holding tool in the pipe plug inline with dizz and plate just above
Oil pan parting line.I am not sure if oil pump will fall though plate opening
Parts houses sell holding tool.

I will first try tightening the six bolts. If I remove the six bolts and drop the plate, will the pump fall out?

Yes, the pump will come out with the plate removed. As Big Hammer said, buy the cheap tool to hold the pump in place. When the plate is off check the spring that holds the pump up. If it has any rust pits be sure to replace it. Springs with rust pits break easily and that would let the pump fall down and really mess up the engine. I bought an engine once where this had happened. I didn't know that when I bought the engine, but as soon as I rolled the engine on it's side I heard a loud clunk and knew I bought scrap metal. Actually it's rebuildable, but sure not the engine I thought I had bought.

BTW, your pan is a 1928 feature.

Please forgive so many questions, but I have no previous experience with a Model A. I looked at the side of my engine. Just above the pan, in line with the distributor up above, is a port going into the engine. There is a fitting with some sort of flat disc-type top on it and then a line from that fitting runs to the back of the engine and up in through the firewall. I am assuming this is the line to the oil pressure gauge.

How do I remove this fitting? I assume I would first undo the nut that connects the line going up to the firewall. Then how do I get the fitting out of the block? Do I just grab it and spin it counterclockwise to get it out of the block? Once the fitting is out, I would guess I would insert the pump holding tool and tighten it up before I would remove the plate on the bottom of the pan.

fins2nv, you are correct in the removal of the line and installing the tool.

BTW, the cost goes up for each question after you exceed your daily quota.

Thanks Tom. I have $2.50 left in my pocket!
