Oliver 1755 White smoke from cylinder #2

Bkreiser · Oct 10, 2023

I pulled the exhaust manifold yesterday and found that cylinder 2 is puffing white smoke. I went ahead and pulled all of the injectors and took them to the local injector shop and had them cleaned, tested and set to the same psi. After re-install the tractor still smoked from cylinder 2. I also swapped injectors from 2 and 6. After that exercise I pulled the valve cover and adjusted all of the valves. Most of them were at .028 and I adjusted them all to .030. Still the same results. I would like to do a compression test but I am not sure where to get the correct fittings? I have heard of people gutting an old injector to make it work. Does anyone have info on what to use. Also any other ideas to help a cylinder out? I am guessing it is a compression issue.

if the tractor had been sitting the rings could be stuck in that piston. went through the same thing on my 1755. let it sit a week with atf
in the cylinders. just try the thumb test on that cylinder for now comparing it to the rest of them.

Remove injector and with valves closed pressurize the cylinder with shop air and a blow gun with a rubber tip. You'll be able to find where the air is going. You may want to remove the
push tubes so the rockers don't hold the valves open depending on engine position.

White smoke usually means water doesn't it?

Usually yes, unless diesel, then light blue (diesel) is sometimes mistaken for white smoke, which could be the case here. I'd check coolant levels before and after running a while, or pressurize the cylinder and see where the air is going.

Thanks for all the help. I am going to be using it some this weekend and then I will pull it back in and try the pressure test with the air hose. I did end up finding a compression tester that I can use so I
will check it with that as well.

Thanks
