Well there are lots of pros here with this oil catch tank and not any real cons that I can think of. The pros include the following: The oil catch tank is well designed and seems to be manufactured to last for the long haul... It has worked perfectly for me so far...and I'm not really worried about any leaks with it. Mounting was a little bit harder than I thought it would be but that was to be expected. In my humble opinion this is more than A great value, and it comes highly recommended from me.
