oiling timing chain 2.0
This bolt is made from 9/16 hex bar stock, turn down and threaded, step drilled 1/8 throughout the shank. Then back drilled with a 1/16 at the very end of the bolt. The head of the bolt is twice the height size to be drill and taped for a 1/8 npt fitting, without compromising the bolt strength.
The copper line and fittings were used in the first mock up and no pressure drop was noted, although I am using a high volume oil pump in this engine build. One of the compression fittings leaked and no matter how many times I change out parts it continued. I blame this on the quality of the parts, fine China.. lol
I will continue this project using #3an fittings and hoses, it would be more robust in mounting and pressures involved. And it would open up the door for inline oil cooler.
