I was wondering if I put Tilley wicks saturated in meths around the injectors and lit them if it would warm up the injectors enough to vaporize the fuel better. Anybody ever try it? No but I have warmed a reluctant deisel with a blow lamp before now, heat inlet manifold and then crank. Another tip is to cover, if you can, the inlet port which can make the engine spin a lot faster, remove the blockage and inertia helps to start it. Usually easier and less likely to cause problems - pull the 'Engine Stop' decompressor for a second while the engine builds speed/inertia then release. This sometimes gets you going if the batteries are a bit low. A cautious squirt of ether can help too but mustn't be overdone.

baked-idea.co.uk: A cautious squirt of ether can help too but mustn't be overdone. Not enough can be said for NOT squirting explosives into the intake of a small, LIGHTLY MADE diesel engine. DON'T DO THIS! Notice it says not to do this right in the manual! Big, giant diesels that weigh tons can withstand the occasional blast of ether exploding BEFORE the piston reaches TDC, which tries to push the piston down in the direction it was coming from. Little light diesels, like the one in your sailboat CANNOT. Premature explosions from ether or "starting fluid" from auto stores in a spray can WILL, not may, detonate on the compression stroke. You'll hear a loud knock, if you get away with it. You'll hear a loud bang if it blows the head gasket or blows the head off or breaks the little aluminum piston. Diesels run on the heat of compression. There are two ways of artificially creating this SAFELY when they are cold.....preheat the cylinders, preferably with glow plugs...or preheat the air, preferably with an air pre-heater in the intake. HEATING THE FUEL DOES NOT MAKE THEM START! Diesel fuel explodes because it is finely sprayed into superheated compressed AIR caused by the heat of compression....22:1 or more compression. (Remember how hot the bicycle pump cylinder got pumping up the tire?) The heat gun is a great idea if you have a power source to run it from. Let's avoid lighting fires in the engine compartment fumes of fuel and battery hydrogen to crank them, ok? Thanks! The usual reason why they won't start is THE COMPRESSION IS TOO LOW or THE ENGINE DOESN'T SPIN FAST ENOUGH....both of which, of course, require corrections that cost $$$$. Gas engines will run with worn rings, poorly closing valves, leaky head gaskets.....diesels will NOT.... Larry -- We tried to tell you to change the oil every 100 hours or THREE MONTHS....(sigh) |

Larry -- We tried to tell you to change the oil every 100 hours or THREE MONTHS....(sigh) Another possibility is that the oil is too heavy for cold weather. Don't know how well multi-viscosity oils work in diesels, but maybe changing to a lighter weight would help. And removing 20 years of built-up sludge... ;-) While possibly not recommended, a friend with a diesel Mercedes of ancient vintage once had me spray WD-40 into his engine intake while he cranked the motor. Being essentially kerosene, this would be much safer than ether, I think. |

The manual suggests 5W40 when below -20F, but I live next to Salt Water, and it rarely gets down that cold, here. Much easier to keep one type of BaseOil in Stock, when you can't just go down to the store and buy what you need. For the Rolling Stock, (vehicals) I am using Delo 100 15W40. Snowmobiles are all 2Cycle, so they use their own YamaLube II. Bruce in alaska who got the WebCam up and running yesterday...... -- add a 2 before @ |

![]() Not enough can be said for NOT squirting explosives into the intake of a small, LIGHTLY MADE diesel engine. DON'T DO THIS! Notice it says not to do this right in the manual! I worked in a Detroit shop when I was a kid. Mostly fisking boats and logging equipment/trucks. Got to do basic rebuilds on 53, 71, 92 series. The head mechanic took me asides and showed me two 6-71 engines in for a rebuild. One operator used ether regularly caus it was cheeper than a new charging system and new batteries. The other operator never used the stuff. It was stunning to comapre the two during de assymble! The heat gun is a great idea if you have a power source to run it from. Let's avoid lighting fires in the engine compartment fumes of fuel and battery hydrogen to crank them, ok? Thanks! Concure............................ " ...flames on boat.......bad."
