Copious blue grey blue smoke comes from the exhaust of my 1971 140. It's a real fogger, lightens a little after few minutes under load, but fogging resumes when idling.
It uses about 1/2 quart oil every couple hours and the plugs are wet with oil and grime. It runs really well mowing with a 6 ft woods mower going up and down hills with plenty of power. Oil pressure runs at the second mark left of 75 on the original gauge, which is the 1st mark right of vertical. I'm guessing at least 40 psig.
A Compression test shows all cylinders between 155 and 160 psig.
There is no water in the oil and the radiator water level stays constant.
I bought the tractor in 2004 in great shape and have put less than 500 hrs on it (<30 hrs/yr).
I would like to fix the oil burning problem and continue using this tractor, but I don't have a clue what to fix or look for. Any advice is greatly appreciated.
I was considering sending it to the local shop for an engine rebuild but maybe that's overkill.
