That's a common crack, get yourself a plug, thread it in and have it welded up, that's about all you can do with it ,

No, you can't pull the plug back out, you'll.have to.get your oil.pressure reading elsewhere, and in a perfect world, you could try and drill a hole at the end of the crack to keep it from spreading, chad

I have a 94 evo and unfortunately I had a similar crack... but mine went down in a line, and was definitely due to my putting in a gauge at that location and not being careful about over tightening. It is a common area for a crack. Mine did not pour oil out, but only weeped. I know I will get some flak on this but I used JB weld on the location after securing oil to that area, cleaning it very well, and then using the original sending unit back in the hole with a healthy dose of JB on the threads also. Has not leaked, but time will tell. I do want to mention to you that this area CAN be welded, and the previous suggestion of a plug there is valid. The problem though is that it takes a LOT of heat to get the area just ready for welding, let alone welding there.
