Re: Detroit diesel 353
First of all lets get the facts straight. It is a 2 cycle engine, Yes it has liner seals above the airbox area, yes it is possible to get coolant in the oil from either top or bottom. Does it have coolant in the oil??? Check the dipstick for white colored oil or moisture/rust on the dipstick. Maybe from the 'o' rings from the liner but most times not. You would have to have the airbox drain tube[slobber tube] plugged before the coolant enters the oil pan. Possibe though. Remove the rocker cover, pressureize the cooling system to 10 psi and watch for coolant leaking around the injectors. Keep in mind the injectors do NOT have 'o'rings on them. NOT. you are looking at the copper's just around the injectors. If they did the job properly the coppers will not leak. Next is to watch the air box drain while you do this pressure test. If the coolant drains out the air box tube then your liner seals might be fried or leaking. Also if the injector copper install was improperly done the injector tube can leak inside the combustion area and cause white smoke from the engine while running. Bar the engine over while watching the drain tube. Next is to remove the oil pan from the engine. Watch where it comes from. [I am assuming you have coolant in the oil pan]. remember it is possibe to get coolant in the oil pan from the air compressor as well.
Are you sure that the white smoke is not from air in the fuel system?? install a pressure guage on the OUTLET of the secondary filter or on either fuel rail on the head. You want about 15 psi at idle and 55+ at no load speed. Watch for this one...... YOU need a restricted fuel fitting on the return rail before the fuel goes to the fuel tank. The fitting will be either a 'R70 or R80 stamped on it. either will do. This keeps the fuel pressure in the head while running. Also try this, run the return line into an empty bucket, watch for about 30 seconds and then place the fuel line down in the fuel. You are watching for bubbles. There should be NO bubbles in the return line. Also get your watch out and measure the flow of the fuel. You should have .9/g/min @ 1200 rpm. Let me know how you do. BTW, these are the tests I do when trouble shooting white smoke complaints

It is said if you sit by the river and watch the water flow by long enough, your enemies will pass by. This I believe to be true. It is also possible to watch your loved ones pass by as well.
