120 HP F.L. (2715E) No lubrication to the top of the motor. The front 4 rockers and pushrods are dry, dusty and rusty. No sign of flowing oil even at 2,000 rpm with the valve cover off. Good oil pressure (60) I had replaced the rocker shafts last year, they were plugged and worn from lack of lubrication. I had good oil flow for a short time after the new shafts were installed, Twenty hours run time found the front four valves TOTALLY out of adjustment, in fact the front pushrod had fallen out of place. I have the "SABRE LEHMAN POWER" operators manual with parts identification. It is missing page A11 which is also A12. does anyone have one?
The best advice I have received, including from Brian Smith, is that the bearing or bearings on the cam have slipped or turned and blocked oil passages. The engine has to come out! dang!!
By the way. When I had the valve cover off yesterday and found the problem with the front 4 valves. I removed the old adjusting screws as they were beat down and nearly flat on bottom (knob end). I used 4 new adjusters on those front 4 valves and tightening them down until the shoulder of the bold was right down tight to the rocker and the valve was still way out of adjustment and almost "floppy". This indicates to me that the cam or at least the lifter is also badly
worn.
Single engine , quite a bit of working room but the generator would have to be moved to pull the cam (Probably not possible). Brian Smith says that to get the lifters out, the engine most probably would have to be turned upside down. This would be almost as difficult as pulling the engine. Local diesel specialist (trusted) tells me that the new cam bearings are nearly impossible to install in the boat.
So this week the process begins. If there is any interest in the entire process, including pictures, commentary and cost figures I will document it for this forum,
otherwise I will just suffer in peace.
