Several possabilities. One is a bad PCV valve if it leads to that bank of cyl. Another is the intake gasket for that side of the engine. Worst case, but not likely as it is affecting all of the cyl, is a failed head gasket. One question, are the plugs fouling with fuel or oil? If over fueling, it could also be an injector or injector wireing issue. Could it also be bad oxygen sensors? If there are four oxygen sensors on this van, and the one for the right bank of cylinders is giving the wrong reading, that could cause this problem. Seems unlikely, though.
Attempting to burn raw fuel Not running on all cylinders Check spark plugs plug wires Do a compression test to see if problem is internal (bad valve, piston)
No, that's usually water getting into cylinders.
remove the spark plugs and crank it without starting it and that should clear out the cylinders then clean the plugs with carb cleaner and install them .then start it . it may smoke for a few minutes.
Not running on all cylinders Check plugs, wires Do compression check
It sounds like you need to change your valve cover gasket.
head gasket lead Black Smoke is too much Fuel getting into cylinders, BLue Smoke is Oil leaking into cylinders and being burned, White Smoke is Coolant (or water) leaking into cylinders and is being converted to steam that gets blown out the exhaust pipe. TommyTrouble
you can use ngk or Bosch it will perform very good, but please don't change the spark plugs when the engine is still hot because it will smoke
Burning excessive oil in the cylinders is the culprit. Scored cylinders and broken rings will usually contribute to blue smoke. Once it turns black, the engine is toast!
Spark plugs don't smoke. A bad alternator would cause a dead battery.
is there blue smoke coming out of your exhaust? if there is then there is probably oil leaking into the cylinders.
Well, one has little to do with the other. If you have too much oil in your motor, drain it, change the filter and put the appropriate amount of oil in it. If the spark plugs have oil on them, or if the car blows blue smoke out the tail pipe when you step on the gas, you probably have worn piston rings on the cylinders and changing the plugs won't help, at least for long. Have a mechanic do a compression check on your cylinders. He will be able to tell you then how your piston rings are holding up. If they are bad, have them changed (not cheap at all) and then change your plugs.
White smoke is water getting into the cylinders. Blown head gasket, cracked block or other serious issue caused this. If it cranks and will not catch, they plugs may be fouled from the water. If it will not crank at all, you have a frozen engine. This is often terminal for the car.
Generally speaking, white smoke is a sign of a blown head gasket, cracked cylinder head or any defect allowing water to enter combustion chamber. Remove spark plugs and look for one that is noticeably cleaner than the rest. That's the problem cylinder or if 2 adjacent plugs are like that it is a crack in the head gasket between those 2 cylinders.
Depends on the color of the smoke:light blue/white sweet smelling smoke, a coolant leak into crankcase.dark black smoke, an oil leak into the cylinders.etc.Check with your mechanic.
Not all cylinders firing? Check spark plugs/ wires Do a compression test to determine which cylinder is not firing
Check the oil level, if you put to much oil in it can cause smoke. If that is the case then you have to drain some out untill you have the right level then let the truck idle untill it burns the oil out of the cylinders. Or you may have blown head gaskets
"white smoke" is steam, which means coolant is getting into cylinders. usually means cylinder head gasket or cylinder head is faulty
Not likely. Smoke from under the hood denotes a leak. Either your coolant or oil is leaking. White, thick smoke is oil. Could just be a gasket. Thinner hazy smoke is coolant. Check your hoses. Look for fluids/wet spots. Bad plugs can missfire, and make your exhaust smoke.
Not all of the glow plugs are working
Could have a head gasket problem. Need to know what color smoke is coming out of exhaust. If the smoke is white and has a sweet smell to it, you have a bad head gasket or a cracked head or both.
you will either see coolant around where the head sits on the block,or,white smoke coming out of the tailpipe. at that point coolant will be getting past the head gasket and leak into the cylinder or cylinders. also check your spark plugs and do a test to check for exhaust gases coming out of your radiator.
One reason that a lawn mower may begin to smoke is that the oil chamber is too full. Spark plugs that have burnt oil and are not cleaned can create smoke and other exhaust issues.
Try changing the spark plugs
Kinda vague huh? from the first impression it sounds like you blew a coolant hose and the smoke you saw was steam from the coolant hitting the manifold. But if you had to remove the spark plugs to see the water then you have blown a head gasket.
water on the cylinders from a blown head gasket or cracked head.
