External Rb30det Oil Drain

[nizluxrb30det]

I have put two 1.5mm oil restrictors into my engine block, i still have head filling up with oil. Should have went with 1.2mm. I want to know if the drain into the bottom of the engine block, will be able to handle oil from the engine head return, from the front left, and also from a second return which will come from taking out the grub screw in the middle of the exhaust side, in conjunction with the turbo drain. Or will i need to make a fitting into the sump and leave only the turbo drain to the engine block.

Also is the grub screw that I have taken out too low in the engine head and drain too much oil at idol or will it be fine?

the grub screw thet i have taken out is the brass fitting above 3 and 4.

1 problem i see with running a rubber hose from there would be that it wont last too long with all the heat from the manifold.

Should really run a drain form the back of the head

yea i will definitly be running some hi temp braided hose and with some insulation fire/heat resistant pipe overlay. Its just easyer to run the hose from there. I dont have much room from the fire wall as the motor is in a hilux.

You could try doing it by taking the cam covers off and getting some barbs welded on at the lowest point at the back. Then just run a couple of elbows and some line back down to the sump.

I have the same problem with my RB30DET, seems the best cure is to fit a oil return on the back of the head, down to the sump.
