Catch can for a 3.1 MU. 2.8 is the same but you will need to weld a fitting to the dipstick tube or manually drain the can.
First on the drain fitting, get a ball that just fits inside the fitting. I just used a ball out of an old bearing.
Then put a dent on the fitting so the ball does not fall out. This acts as a non return to stop any oil pushing up the dipstick tube and filling the can while running, when the motor is stopped the oil will drain back past the ball and run back down the dipstick tube into the sump

On the dipstick tube you need a tee fitting. In this case it was 5/8”x5/8”x1/2” for the drain hose

The can I used can be pulled apart so it can be filled with stainless steel scouring pads and fitted with a tube on the inside so the oil is at the bottom of the can

Then it’s just a matter of running new hoses from the tappet cover to the fitting with the tube on the can. Then the other fitting goes to the T where the hose went to the tappet cover
