Exactly how much oil is run through the turbo during operation? I had to do some "fabricating" to the oil return tube to get the HTB2 to work, got too serious with a grinder, the JB weld gave up, had it welded so I loss about 1/3 the inside diameter of the tube above the first bend. Haven't seen any signs of an oil back up so I guess it is draining okay, but still wonder about it.
