Race cars → Returning catch can oil to the sump
One thing people tend to add to modified engines is a catch can, which separates oil droplets from the crankcase ventilation hose to stop them being fed back into the air intake and burned.
Most catch cans are just a can, which fills up over time and needs periodic draining, which is messy and annoying - especially when it happens quite frequently on race engines!
Some engines actually have a catch can setup from the factory that returns the oil to the sump. This one came from a turbo diesel engine.
The oil return needed somewhere to go, so I made up a T fitting into the turbo oil return line.
This setup is still a bit experimental, but it will be interesting to see how it goes. The main concern is that if there is too much oil in the turbo oil return it could cause a restriction and force some oil past the turbine oil seal.
In theory there will be no difference in pressure in the system, but if there is too much flow from the catch can it could potentially cause problems.
