Use a timing light... the strobe effect will let you see the oil sling from it. You wont be able to confirm exactly where its coming from but you should be able to confirm that its leaking before you pull it. Then your converter guy can pressurize it and put it in water just like a tire to pinpoint the leak.
That's a great tip! Thank you! I hope I never need it!

| If you wash it good with Brakekleen then spray foot powder around the area you suspect. The powder will show the trace of the leak. Timing light is a good idea. I've been a witness of the pressurize the converter with air deal. They make a fixture to hold the rubber plug in the converter so you can apply regulated air. When I saw it done there was no fixture and no regulator, don't try it. |

| Great job on finding your crack. I also had to tig weld up a crack at one of the convertor ears. Mine was easy to find but the heat trick you did was genius. Like everything else after the fact makes a lot of common sense. Thanks for sharing. |

update for you.
was able to find a very small leak at the end of a weld on one of the pads. i put a piece of card board under converter to determine where leak was at. removed converter and stuffed the neck tightly with a air nozzle and some rags enough to pressurize the converter and started spraying each weld with soapy water. I had to take a propane torch and put some heat on each lug to get the crack to open up some until i found it.
how can a crack so small make such a mess. i was about to throw in the towel before the heat trick. i guess once it gets hot and under pressure it leaks worse.
how much pressure is in the converter just for future knowledge.
ep-i was going to do the foot powder trick as i feel that would have found it but i forgot to grab it from the house before i left to the shop.
thanks for the help fellas. this was a community find and i appreciate it a ton.
