Tht is the most likely cause. To find out which cylinder it might be,Take out your spark plugs one by one. If one is super clean then that is the cylinder that is loosing coolant. you can then try to seal this cylinder using heavy duty sealant. You can get this at an auto supply depot. You drain all antifreeze, refill with water, run with spark plug from that cylinder removed. Just follow instructions on sealant.

TODAY I GOT P0302 , P0202 fixed and also replaced all plugs in this 06 DTS..It blowing white smoke and smells like gas..What's the fix for this?


One injector (#2) is not working properly causing misfires. This can be because the injector has failed, the ignition control model driver for that injector has failed, or there is a wiring problem between the module and the injector. Most frequently, it's the injector and you could start by replacing it, but it's complicated and if it were me, I'd take it to a GM dealer for diagnosis and repair.

Coolant not staying, smoke and smell for the exhaust jeep liberty 2002


Borrow a radiator test kit from autozone or buy one fro harbor freight. Pump it up to around 18psi to See if it holds for about an hour. If not you probably have a blown headgasket. If its white smoke...its your coolant being burned in the cylinder and vaped out your exhoust..

White SWEET smelling smoke, or white OILY smelling smoke? If it's white thick SWEET smelling smoke, you have a blown head gasket - that's the smell of antifreeze burning in the engine, which it should NEVER do. If it's white OILY smelling smoke (smells a lot like diesel), then you're getting too much fuel into the cylinders.

If it's sweet-smelling smoke (antifreeze), pull the oil dipstick & check the oil level. If the oil level is HIGH and the oil looks like a mocha milkshake, that's absolutely conclusive - that's what happens when antifreeze gets into your oil, and it's nasty corrosive to engine parts.

I'm not at all surprised that the oil light is on if it won't start - you won't get much oil pressure until the engine is running.

White smoke coming from exhaust, smells like gas


Check the fuel pressure regulator. It should have a vacuum line attached to it - disconnect the vacuum line and turn the ignition on - if fuel come out then that's your problem. DON"T do this while the engine is hot or you could start a fire!

94 COUGAR GETTING TOO MUCH FUEL WONT START


my guess would be a defective fuel pressure regulator, not 100% but i have seen that before ,usually a bad regulator will usually produce a rich (gas) smell and or very white thick exhaust smoke(raw unburned gas),almost the same appearance as smoke from a blown headgasket, and also usually if you hold the thottle to the floor,and crank it for several secs it sould start,if not another alteritive to getting it to start(as to check for white smoke) is to pull the fuel pump relay to stop fuel flow long enough to get it to fire,once it does replace fuel relay,and crank holding it to floor tiil it starts,hopefully this will help you ,good luck
