Couple years back on a hot summer drive north.I ran it for a short time at around 210 degrees before I noticed. I'm not sure if this may have caused the problem? We parked till the evening cooled down and continued our trip. Later I hosed the radiator area and washed out a lot of debris. I believe after that is when I first noticed it started to smoke on start up. At first it was for only a few seconds. Later it got worse and smoked longer. But only the first start of the day.(White unburned fuel I think?) While up north on that trip I had a mechanic replace the left injectors. It did not fix the smoking problem. I also found fuel in my oil on the way back south from that trip. I changed the oil twice on the way back to Fl. from Wi.I was concerned on the oil getting thinned too much and the level getting too high in the pan...After I got home I found cracked and broken fuel lines under the lft valve cover.(overtightened maybe or Old??) I put new ones on. After which I should of taken it for a good run to make sure everything got oiled up well. I made the mistake of letting it sit too long although I did change the oil again after I got home. After sitting so long and everything washed out so clean from the fuel in the oil on the way home it must not have had enough lube in the injectors so they were all stuck upon starting it last year. So I had to replace all the injectors this time. (rebuilt Detroits) Guess what Still smokes White upon start up left bank. now it smokes for a good 15 or 20 min., then its fine. I can run and stop all day and it will not smoke untill it sets all night. I would like to fix the problem. I started to disassemble and am ready to pull the left head. What should I look for? Sorry for such a long read! Alex |

Have you checked the antifreeze level. White smoke can be antifreeze as well as unburned fuel. See if the exhaust smells like diesel fuel or sweet smell like antifreeze. Does the engine run smooth or if it is a little rough on idle maybe you have a stuck ring or two. They will losen up with heat till next time. You said you replaced the injectors with rebuilt ones so they should be okay. Bill |

Bill, Thanks for your response. Best I can tell it smells like diesel fuel. I believe it does run just a little rough for just a short bit. I can't run it now,Ive' got it somewhat dissasembled right now. I'm in the process of taking the top of the gov. off so I can disconnect the linkage to the rack, so I can pull the head. Antifreeze level was right before I drained it. Alex |

The white smoke is probably telling you low compression in one or more cylinders. You could have pulled back the exhaust manifold on the smoking side and started it up to see which cylinder. Too late now. It's a good sign that the coolant is not going anywhere, if you are lucky you may not have a cracked head. I've always made it my personal policy to never take a 2 stroke over 200 deg. Any higer is a roll of the dice. You might or might not damage it. Good luck! |

"Later I hosed the radiator area and washed out a lot of debris.

On the older MCIs, the radiator compartment on the driver's side
contains the pick-up port for the air filter... Is that the same as on
the eagle? If so..... did the radiator compartment flush get too much
water into the air cleaner?
(I always like to rule out the easy, "no-brainers", before moving on
into the high buck zone$.....) |

John mc9, The radiator has an aftermarket (for dash air) ac condensor attatched to the face of the radiator. It tends to be a catchall area and I found out needs to be hosed out once in awile. I leave the condensor still hooked up I just unfasten it from the radiator and swing it away far enough to be able to run a hose in there. I'm sure I have not gotten close to the air cleaner inlet. Thank you for the precaution, I'll keep it mind. Alex |

Mark (Boomer), That's a great idea on starting it after the exhaust is off. Maybe I still can do that? I'll double check everything. I have the Thermostat housing off and lot of the water piping. I believe it wouldn't take all that much to start it for a few minutes and watch the exhaust. I also had a hunch about low compression.
It would be nice to know which cylinder to pull.
thanks for your response. Alex |

After you do the above and figure out which cylinder is causing the smoke, another thing you can do is pull the air box cover off for that hole, roll the engine over and with a good light take a look at the condition of the rings. It might be possible that you have a leaky injector too. If it dribbles fuel into the cylinder after sitting cold for a few hours, it will cause a lot of momentary smoke and misfiring on start up until that cylinder burns off the unburned fuel. If that's the case, you are in luck. I wouldn't pull the head until I knew for certain it was not an injector. If , by chance you installed DD Reliabilt injectors, they are prone to being no good. One time I installed a new engine with Reliabilts and 4 out of the 8 failed within 300 miles. Never used 'em again. |

If you are able to locate the cylinder causing the smoke try changing the injector to another cylinder and see if that cylinder smokes. If it does it is a faulty injector. Don't run the engine for more then a few seconds with no water in it. Bill |
