I have a Brute Force 750, starts OK but runs rough after a few minutes, will start smoking a smelly black/gray smoke, and most recently some blue smoke.

When the head gasket fails on a liquid (water) cooled engine the typical smoke colour is white (steam) and that becomes rather underlined by the steady drop of the coolant level and often clear evidence combustion gas is leaking into the cooling system.

Smelly black/grey smoke tends to be produced by an over-fuelling condition such as a stuck choke or strangler or other cold starting aid or perhaps carburettor flooding.

Blue or blue/grey smoke is invariably engine oil burning but I suggest you ignore that until the black smoke problem is rectified and after a short time the blue smoke might also disappear. If it doesn't it could be related to the overheating but the black smoke probably wasn't caused by that...

If your after market turbo is blowing oil into the engine, best you have it removed. When you say that fuel may be leaking into the cylinders, it could be leaking fuel injectors. If the smoke out of the tail pipe, it's usually indicator of burning coolant. Blue smoke is indicator of fuel and black of oil.

I have true duels on my 1986 chevy pickup. It has a 305 motor. It only smokes on the passenger side of the tail pipe blue smoke only when the motoor gets hot. If im going down the road it stops. When I...

Bad news. Depending on what your mileage is, you can have a burnt valve, sticking lifter, bad piston ring all on the right side of the engine. The blue smoke is burning oil. Oil from the crank case is being compressed up into the cylinder and being burned. You will have to get a compression check on that side of the engine. You check the compression one sparkplug at a time while the engine idles. A loss in compression will tell you what cylinder is failing.

Good luck and thanks for your question and I hope my suggestions help. burdfrenzy
