Sump + Cooler

[spud69]

The oil level should be set to the original max level on the dip stick, the level is set just below the crank so that frothing of the oil does not occur which will detract from its performance. The most importance thing is if you have chopped the sump is to try and retain oil capacity by lengthening the sump and baffle it, making sure the pick up is close to the bottom of the sump.
If you add a cooler you will need to add extra oil for the cooler and pipe capacity but still fill to the max level on the dipstick.
The most important thing from my experience is to fit a good oil pressure gauge so that you can be sure the oil feed is running properly.
