suby engine oil pan shortened, cant stop the leaks Options

[scotty914]

okay short version of it:

i cut 2 inches out of the oil pan for more ground clearance, and added 2 boxes to make up for the capacity, sticking out of the front and rear of the oil pan.

i welded it all up, used a flood light to look for holes found 3 pin holes that way, welded the pin holes up. then did a water test and it leaked, well more like seeped, i could see the water spreading on the out side, not dripping jet wetting it. so i ground down the first area and brazed it. well i did this about to about 10 places, and some of them more than once ( brazed a larger area )

and still have the seepage problem, could i just por 15 the oil pan to seal the holes or should i keep brazing and looking. and if not por 15 is there anything else i could use.

i so far have used a 3 foot flux coated rod brazing this thing up, so now what

i did not use flux filled rod, i used 1/16 copper coated steel. i did manage to seal it up tonight. i used about 8 feet of flux coated brass rod, its welded for the strength, and brazed for leak proofing. i ground down every weld and the brazed over it. a few welds i could not get a grinder in to so i wire brushed em then brazed. there are about 6 to 8 feet of welding on the pan 3 pin holes is not bad, but quite a few more weeping spots. i did lose about a 1/2 quart of capacity, but that i can live with for 2 more inches of ground clearence on the oil pan.

and the motor is a 98 2.5 from a legacy
