90WLSP36 Smoke and heat - williamcharrison - 11-21-2005 06:40 Thanks to all who responded. One thing I notice is that there is no oil smoke after the engine warms up. Doesn't this say that the problem is not the rings? Chuck Harrison Akron, Ohio 90 WLSP 90WLSP36 Smoke and heat - pattypape - 11-21-2005 06:59 On our 88 FC the only switch is a circuit breaker in the 110 AC Load center panel. It is labeled Block Heater. Some BB's have an on/off switch in the co-pilot feet seat area on the floor. You probably know to plug into 110 AC shore power. Four hours is probably sufficient time. Many school district busses are plugged and warmed overnight Bill 88 FC Michigan --- In WanderlodgeForum@yahoogroups.com, "williamcharrison" > > Thanks George, > I tried an experiment, I kept the bird in our heated warehouse > over the weekend and when I started it this morning there was little > or no oil smoke.

There is no switch for it. You have to turn the breaker on for mine. Don 89 SP 36' Butler, PA Thanks George, I tried an experiment, I kept the bird in our heated warehouse over the weekend and when I started it this morning there was little or no oil smoke. By the way, how do you turn on the engine preheat? --- In WanderlodgeForum@yahoogroups.com, "mrdonut12" <mrdonut12@y...> wrote: > > > > Chuck, > Although the smoke is getting worse, the weather is also getting > colder.

The smoke most likely has a very strong diesel smell to it. Oil smoke would smell more like burning oil (duh). ;o) My results are the same--cold engine, lots of smoke, warm engine, very little smoke on startup. Happy I could help.

Diesel fuel is oil and it will have a oil smell but the prob is not burning oil it is unburned fuel oil. Modern diesels have computers to control the emissions but those engines would smoke untill warm up if the computers did not take actions to prevent this. If you notice diesel tractors on construction sites that do not have mandatory computer controlled emissions, they smoke alot untill warm. Piston rings are not the correct size untill the heat goes up to Mfg thermostat setting. That is why it is not a good idea to replace the Tstat with a colder one. The viscosity of fuel oil and lube oil is thicker and spray patterns are not correct untill the temp is up. Running the cold engine under a load causes the pistons to run ascew and ill lubed. If after warm up a emissions screening shows unburned fuel it may be time to have the injectors cleaned or the rack adjusted on the pump. You see more smoke for two reasons, 1- now you look back in horror 2- modern diesels dont smoke much and you compare. My advise is 'Dont look back' and have a cat dealer gyro test it warm befor you spend any money on needless repair.
