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.
