Turbo oil feed. - Anjay1 - 06-30-2020

There's probably at least a dozen different engines you could be asking about, I don't have any for sale but you'd need to be more specific
RE: Turbo oil feed. - Anjay1 - 07-03-2020
LYes, you are right. Forgot to add it is for om606 engine. I just need the end which treads into the engine block.

Your best bet is to make one as most of the factory ones are a bent hard metal line. That way you can use whatever turbo and manifold and it will fit. Just buy a flexible -3AN turbo feed kit around 2-3' in length and buy the correct -3AN to metric thread adpater to fit the block. Let me check my purchase history and I can tell you the size here shortly.... something like M16x1.5 for the block side but don't hold me to that just yet!
RE: Turbo oil feed. - TwoMuchBoost - 07-06-2020
Ok, yes the engine block is a M16X1.5 but I remember now the difficulty is sealing the fitting to the block because the factory hardline is a 10MM bubble flare kind of like a brake-line. The fitting I found on amazon awhile back is pretty similar to this

The trick is sealing the shoulder of that fitting to the block; since the factory line seals inside the block via the bubble flare line, the outside of the block is exposed to the elements and rusty. I cleaned up the oil feed boss with some sandpaper and used a crush washer/sealing ring. I added a touch of RTV silicone to be extra sure the rough surface would seal. After that, you can use any -3AN or -4AN generic flexible turbo oil line feed kits. For the drain you can just chop the factory tube in half and use flexible oil rated hose thats 3/4" diameter.
EDIT: I found the same fitting but in steel... a little more expensive but way more sturdy so you can really wrench down on the fitting to make the sealing ring crush down. I was really careful with my aluminum one and cheated with some teflon tape and RTV. Still holding to this day but this fitting looks way nicer.

Thank you very much! This is very useful information. My problem was that I couldn’t find the block fitting but with your info it will move my project forward.
