My 75 Westy was running fine in the garage. Started it up just to charge the battery and blow out the accumulated moisture from the exhaust system. It has been very cold lately here in Kentucky. Running very well but when I came back to it after looking for somethink with my wife, it had oil pouring out in a stream about 1/4 inch diameter from the left rear of the motor. As I said, it was cold out and I was disgusted that I couldn't go for a drive. Oil light was on and motor still sounded normal and was almost off fast idle. I shut it down immediatly so I am assuming no permanent damage. Hasn't been warm enough when I am off work to check it yet. I am thinking oil filter seam or pressure switch broke. I rebuilt it less than 5k ago and has run great with no problems till now.

The pressure switch is the easiest thing to check and the cheapest to replace. They can blow the top right out and leave about a 3/32 hole pouring out the oil.

Well finally warmed up in the 40's with a NorthWest wind. Pulled off the oil filter which is a Mann filter to check it and a clincker fell in my drain pan. Cheched where it came from and it is out of the back of the block by the oil filter adapter. Guess I'll be pulling the back end of the motor off to get to it so I can reinstall and peen better this time. What kind of sealer should I use?

It sounds like you are talking about one of the galley plugs? Not sure the best way to replace ones near the filter without tearing the engine down so that you can blow the galleys out when you are done. If you drill and tap, you must get every last shaving out.

You might use JB Weld combined with peening and some kind of screw and washer to lap over the head of the plug for now. This combo has worked on one of the ones behind the flywheel on my 1800 for decades at this point.

If and when you do pull the engine down for some reason drill and tap all 11 (10 on mechanical fuel pump engines) galley plugs

Thanks on that info. I had all the ones on the flywheel end tapped when I had the block cleaned when I rebuilt it. It is an 1800 with the weber progressive. Seems to run fine once I finally got the jets right and the German 009 set right. Only has about 3K since the rebuild even though it has been 2 years. Has a really good body since I got it in Santa Fe,Nm. I don't drive it in the winter if there is rain or anything on the road.
