I recently purchased a CAT turbo diesel generator. I checked the oil and it had water in it. After a good bit of clear water came out the oil started to drain. It could best be described as the color and consistency of a vanilla milk shake. I was told by a friend to mix some diesel with the oil and agitate it to mix it up, then to drain the oil. After the system was clear, i put fresh oil in until it reached the fill line. I started up the engine and let it run for about two hours. It was smoking white from the exhaust stack. I have also noticed that there is oil dripping from the exhaust stack. There also seems to be oil leaking from the turbo. Could this oil leak be causing the white smoke? I remained curious so i grabbed an infrared thermometer and started checking around. The exhaust manifold around the number 1 cylinder was about 100 degrees cooler than the other 3 cylinders. What the heck is going on? help would be much appreciated!
When the temp is less that means the cylinder is not firing as often as the others, I agree sounds like water getting into the cylinder one way another from the description of the white smoke, you already know that from white milk shake stuff in the oil. The oil leak from the turbo is probably the main seal for the turbo. The oil from the exhaust is probably blow by. Engine is pretty much toast and needs rebuilt (if possible) or replaced. Running it with a water leak can cause bearing/ ring failure is probably evident from the oil coming out the exhaust.
you have either a cracked cylinder sleeve or a blown head gasket. engine teardown in the forecast sorry to say.
i think you might have a cracked block in this one ,that's one of the faults to those,the blocks was thin,and if not maintained right they would freeze up,the reading you got on the one cylinder may be the cylinder the problem is in also,i bought one of these at a salvage sale,and never did get it to run right,sold it to a friend,and when he tore it down it had a crack in the head and the block,you need to check yours out real good,you may have more problems than its worth,those are expensive to work on also,parts are very high,so be careful,and don't get in too deep on it,good luck with it.
you are getting water in the combustion chamber you have a leaking head gasket or blown head gasket or a cracked head smoke coming from exhaust that is white is actual steam from 1 one cylinder there is where you problem lies and my be a bad turbo oil leaking from it and exhaust
as far as the water in the oil id say condensation,change out the turbo w/acat reman unit check valve adjustment this may cause your cylinder temp difference also could be a worn injector 100 degrees isnt al that much in all reality
