LS external pump dry sump Hi,
On the LS engine, if I've got a used motor that comes with all the stock accessories, or if I buy one of the many serpentine belt accessory kits available, how do they work with adding an external pump dry sump system?
Looking at pictures online, it looks like the belt sneaks behind the damper and crank pulley. I don't know how the dimensions on the pulley setups work and whether the belt driven oil pump pushes everything forward. Or if the stock belt location simply accommodates the addition of a belt driven oil pump. Or maybe the damper is normally behind the crank pulley and with this oil pump kit, the damper doubles up as the crank pulley so the rest of the accessories can stay in place?
Thanks,
Sal

Sal, that oil pump belt is where the A/C belt is on a typical LS engine. It’s an aftermarket damper with the provision for a dry sump setup, in that configuration. I’ve seen dry sumps driven from the front of the damper also, for a more forward placed oil pump. There are options out there.
