... for the fitting that presses into the engine block at the bottom of the turbo oil return line.



Thanks in advance!

So the fitting presses in? No threads whatsoever?? If I am going to run the return line from my oil bypass system back into the block (I'm assuming this drips right down into the pan) at this location, I imagine I should probably purchase one of the press in fittings and then modify it to accept the return hose from my bypass filter, correct?



My bypass filter came with a large hose barb for use with 3/4" hose and I was under the impression that I could just thread it into the hole on the side of the block, once I removed what felt like (I couldn't really see down there) a freeze plug.



Any input on this? THANKS!!

Also, THANKS for listing that part number! I am going to check on it tomorrow.



Does anyone know if I'd have a chance of being able to drill through and tap the dummy plug that is already in the block????

It is a "frost or freeze" plug. You would be trying to tap the block and guess where the filings would go? It is a good place to run an oil drain as the oil will go right into the pan. Shadrach
