Recently acquired case 70 xt skid steer w/cummins 3.9. has heavy black smoke under load when cold and is hard to start..?


Run a compression test for the hard start problem. Heavy black smoke indicates unburned fuel. Have the injectors flow tested.

Black smoke comes from exaust when I start. Could it overfuel and how can I fix it if its a new carb on my 88 2e 12valve


assuning there is nothing major wrong, get some forte injector and use it as recommended. I once had a renault laguna diesel fail an MOT test, a roadworthiness test that is, on emissions...it was absolutely chucking out black smoke but the engine ran well. I put 2 bottles of injector cleaner in the half full tank and went out for an eighty mile drive revving the engine in the lower gears. I returned to the testing station an hour and a half later and the engine was running perfectly.
Alternatively, assuming the engine runs well but is just a little smokey, have it terracleaned, this will remove most of the carbon deposits from the engine/exhaust and should increase the life of your engine simultaneously improving fuel economy

Engine check light keeps burning


Black smoke is to much fuel. Have the codes read. Driving it like this will burn out the catalyst system. Not a cheap fix.

2001 chevy prizm jerks when in gear heavy smoke out of exghuast


It will help Matt if you would have said what color the smoke is thats coming out the tailpipe. White heavy smoke will be antifreeze getting in the combustion chamber.Could be head gasket,cracked or warped head.Black smoke would be fuel system pumping gas in making it run rich,And not able to burn the fuel completly.

I am experiencing problems with my BMW 320i - 2004 model. It does not start easily. When it starts, a blue fuel smoke comes from the exhaust. this causes the car also to be heavy on fuel consumptio


Blue smoke is caused by oil. Rich running causes black smoke and will set the check engine light. Rich running (black smoke) on startup could be caused by a leaking injector. The blue smoke puff at startup is likely valve stem seals leaking or a bad crank case vent malfunction and sucking oil into the manifold at high vacuum conditions.

Heavy black smoke under load


Sounds like your Mixture needs to be ajusted. To much gas getting to your engine would cause heavy black smoke. I recommend you have someone give it a good tune-up.

Good Luck

Engine light on, heavy smoke and engine burning smell (Audi 1.8T)


First off, how the Hell did they issue a DOT Cetificate, if the Emissions are known to be off the clock. Without causing stress, do you have, or can obtain the Emission Test Result Print Out from the Testing Station test Equipment. This is something they cannot refuse. DO NOT AUTHORISE ANY REPAIRS Come back TO ME with your story.

Black smoke from exhaust


hi nishga
im dave; hope i can help

First you need to determine if it is actually black smoke or if it is blue smoke. There are three colors of smoke that can come from the tailpipe. It is not white smoke obviously because that is easily differentiated from blue or black and generally indicates water or antifreeze leaking past the head gasket and into the compression area of the motor. White smoke is the steam of the water/antifreeze being emitted

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles. The car has many seals, gaskets, and o-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plugs, it will cause a misfire(engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Black smoke is caused by excess fuel that has entered the cylinder area and cannot be completely burned. Another term for excess fuel is "running rich". Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a heavy fuel odour in the engine compartment. Some of the causes of excess fuel are a carburetor that is out of adjustment which is not likely unless you have installed an aftermarket carburated system on your non-carburated car, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or emissions sensor. If black smoke is present, check the engine oil to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Check the above mentioned systems and after detecting the trouble replace the faulty parts and then the engine oil and filter.
