Engine knocking and white smoke

If the smoke is white then you may have a blown head gasket. This is a common failure on this vehicle, especially if it has ever overheated. One of two conditions is responsible for white smoke blowing out of your exhaust. First is normal condition (so you don’t have to panic ) and the second is a not so normal condition which should be fixed as soon as possible.

The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector. The signs would be a loud knocking , like a loose piston rod that could break apart anytime and fly through the oil pan or engine block.

Other signs may be more subtle: a bad head gasket may cause a lot of white smoke out the exhaust-coolant is being burned in the cylinders. White smoke and knocking are symptoms of a failing head gasket. How many miles are on this engine ? It is possible that a small amount of coolant can seep into the combustion chamber through a leaky head gasket, and as the engine warms up, the small gap can close completely.

Have them do a pressure test on the cooling system when the engine is cold. Well, it could be that the radiator or cooling hose sprung a leak, esp if the white smoke was coming out of the engine compartment. When that happens, the coolant could overheat and cause the car to shut down. Since you stopped the vehicle before all of the coolant was lost, the vehicle did not overheat. Now that your engine went you.

As for the noise, I’m not sure. It has gotten progressively worse. When it first started doing it, I added some Howes diesel treatment and that seemed to clear it up. An FCA problem, so I thought.

I swapped out the FCA back in October. We took a 0mile trip, towing our fifth wheel. After a few days, the coolant reservoir was low again. Once there was no coolant, the engine overheated and started knocking and shut down. If that was the sequence, then the engine is probably shot.

If it started knocking and shutting down first or at the same time, still doesn’t sound good. If water is getting into the engine it could cause that knocking noise. The other issue with the knocking could be as serious as a rod through the engine block.

The white smoke is the result of normal condensation which builds up inside the exhaust system. If smoke is being release then this is indicative of a problem. HOWTO looks at all the possible reasons why white smoke is coming from your exhaust pipe. Other reasons for blue or white smoke from engines include: Exceeding the engine ’s oil capacity shown on dipstick. Engine oil capacity is dependent on your specific engine model and can be determined by checking the Oil Recommendation FAQ.

A cop thought my house is on fire when he saw the smoke coming from the backyard where I was parking in the garage to work on the engine. I know it has a headgasket problem and the. I just changed the oil went to start and this happened.

Could I have not enough. Is the white smoke steam or oil vapor? Same with the knocking. It could be timing or it could be a rod. One other possibility is coolant and oil mixed together internally causing a milky mess either in the oil pan or radiator.

The other day, it acted like an injector stuck, lots of white smoke out of the tail pipe and a bad engine knocking. Unburned diesel fuel will make its way through the exhaust completely unused. Be careful of white smoke as it will irritate your eyes and skin.

If white smoke occurs during a startup in freezing temperatures, then goes away, it usually indicates frozen deposits of soot which expanded around the rings then burned away once the engine warmed up. Last evening I saw white smoke coming out from the engine and heard a strange sound coming from it. Being that you have the lb get fixed as soon as possible.

Your injectors are under the valve cover and will leak fuel into the crank case destroying the oil and engine.
