Guys. This Lola T-620 FSV (FA) I'm bring back to life has a mystery in its oil plumbing. I'm new to FSV so seeking advice. This car runs the 1800 cc motor (for FA) which has a dry sump pan which has two outlets. Each outlet was plumbed to the two scavenge ports (the rear most stages) on the six port pump. I'm told this is a Titan pump. Not sure if this pump was "standard" on these engines.
Here's a picture of the pump. Those two oil lines from the pan were plumbed to the two rear scavenge port on the bottom of the pump, which exit at the top of the pump. But as you'll note, the rear-most stage was plugged on top so that stage was not forwarding oil.
All that begs several questions:
1) Is it essential to evacuate oil from BOTH pan outlets?
2) If so, why in the hell would the prior installation block off the top port on that stage of the pump? Why not just not plug the pan's outlet?
3) If both evacuation ports are needed and actively exiting from the pump. is there some hardware to "Merge" the two lines into one before going to the oil cooler (and then to the dry sump reservoir)?
4) Could there a problem of pushing two evacuation stages into one line before going to the cooler? You know 10 lbs in a 5 lb sack?
Any advice appreciated.
