need torque specs for everything from the head up. I'm blowing oil out on exhaust manifold side , not sure if its the head or coming from exhaust manifold as it also looks like its leaking oil in fitting going up to muffler.. maybe seal on valve or something and I will be able to repair only pulling valve cover.I'm have never worked on any diesel motor. this motor has never run hot, I don't do much more with it than mow pulling a 5' finish mower only mowing about 2 acer now days , used to mow around 5, tractor is really over kill, drag the drive once a month with a 4ft box ( about 1400ft) but its all level and I don't really put a strain on tractor.
I have no power lose, no excessive smoke, no over heating but getting a black oil mark on side shield. I have taken real good care of this tractor since I have had it with all the regular filter and fluid changes, has just over 900 hr on it now
