A 1/2 hole in the cam tunnel?
Can you post a good picture of this?
Notch crank bearing oiling holes to match the bearings. These are the oil feed passages to the crank correct?
From the main feed, gotcha.
Possibly bigger for over 7K. Gotcha....
Can you post a picture of this area.
(Yes, oiling is a weak point with me.)
Thanks for helping me (and us the board) !
