I am just about done adding a turbo to my briggs diesel, but I am having problems figuring out where to drain the oil from the turbo. Ive tried searching the internet for a pic of the turbo drain tube, but just cant seem to find a good shot. If anyone has a 31 or 35 briggs turbo diesel, I could use some help finding the right place to put the drain.. A pic would be great, Im pretty familiar with the block, so describing it would work too. Thanks.
