I used one of these cans on my gtr, the problem that ur friends on here have pointed out is that it can still get oil back into the inlet. I ran this as an overflow tank, and unless ur tank is getting full after every drive to the shops and back it should be fine, they work very well. I ended up running this and then to a vented can to the side, then back to the inlet, if u are running it back to ur inlet be sure to put ur return on a 45degree angle to create a negative pressure in the pipe. anything more and it will not be as effective.
Good job on the welding any way, I hope u made it with baffles.
