Ok if this is a V6 and you have no external leaks
and no coolant in your oil
then remove the PCV valve and see if there is a CREAMY WHITE color GOO if there is then the intake manifold is leaking internal
check that and i'm guessing this is a V6
hope this helps let me know

I have a Nissan Murano when starting it up some days a small amount of white smoke come out the tailpipe for 1 sec . but the coolant is green an no oil on the ground mileage 187258


White smoke is a sign that coolant could be leaking into your pistons and getting burned. I doubt that is the case hear as you say it only happens for like a second. I would think what you're seeing is condensate getting burned out of the exhaust which is normal. If you think you have a blown gasket causing coolant to get into the pistons, go have your system pressure tested. If there is a small leak, it's better to take care of it now than to wait until it's really big and then the engine could get destroyed.

Driving home last night my car was overheating and going in to limp mode. i also noticed a few days ago that the heaters only work while on the motorway doing 70 mph.


Sounds like you're low on coolant. That's not good, because it being a sealed system, you should never have to add coolant. The level should always stay full. If adding is necessary it is almost certainly leaking somewhere. If you can't see any external leaks on the engine or hoses or radiator, check your oil sump for coolant contamination: pull the oil dipstick and look carefully for milky brown swirls in the oil. That's the color the coolant gets in the oil. Take off the oil filler cap and check there too for a brown sludge. Just precautions because worst case scenario, if that's where your coolant went, it probably means a costly head gasket job.

If it turns out to be low just from neglect, you may be alright, but you need to keep watch on the coolant level for a good 2 weeks or more to be certain it is not losing coolant somewhere. Be sure and bleed the air out of it too, when refilling coolant. I don't think that was what happened, an air lock, as the cause of your overheating, though.

I have put on a water pump and belt and the car tell sat check cooliant


Check your antifreeze level to make sure it is at the correct level.

Also check to make sure your coolent level sensoe is properly connected.

If both of those are ok, it may be you need to replace the coolant level sensor.

Has anyone had a problem with excessive oil consumption?


just about everyone does with either an old car or a new car with high mileage.how excessive? is oil consumption.well first thing is to check for oil leaks either underneath the motor or any oil lines feed into the motor .any major leaks would be pretty noticeable.if none are present then one would assume that your motor is burning the oil through the exhaust system .check to see what color smoke is coming threw the tail pipe.blue or black smoke indicates oil burning white will indicate engine coolant burning.in any case some color smoke is normal just depends on how much.so lets say your exhaust smoke is normal still could be burning oil just not a noticeable amount.on average you shouldnt have to add anymore than 2 quarts a month or every 1000 miles .depending on your driving conditions if you are having to add more than this there would be a leak some where or heavy color smoke.keep up on oil changes and always add lucas oil usually 1 quart its alot thicker than conventional oil so it reduces engine wear and will handle any small leaks in the engine components like the pistons and rings.if problem still present get to a dealer or certified mechanic as soon as possible good luck.

Is there anything I could add to reduce oil burning in my 2009 Audi A4


A4 always requires adding oil before it is due for an oil change, but only a few hundred miles is excessive. I buy 5 qts when it is on sale. Do you notice any leaks in garage?

I have a 2005 Honda Civic coupe, i only have heat when accelerating and the car is running hot, I have replaced the thermostat, the car is still running hot, I had a test done on head gasket and the air...


there are only three places for coolant to leak.external leak to the outside of the motor,internal leak like a head gasket causing the motor to burn coolant(white smoke out the tailpipe),internal leak(coolant leak into the motor oil.)you say that the head gasket was tested and it was okay then this takes care of burning coolant,however it could be leaking into the motor oil.check the oil level and condition.I would think the tech would have checked this,but check it just in case.if the oil level is good and not thick or white or milky looking then this is not the problem.you could have a leak externally like a hose leaking a frost plug leaking,water pump leaking,this should be checked out by having the cooling system pressure tested a carefully inspected for leaks

Smell gas in oil, check engine light on, collant


Your brother is on to something I believe.

Your coolant is rusty or milkshake-like?

If you arent leaking coolant or oil I think the both being burned in the combustion chambers! Look for oily steam at the tailpipe!

The check engine light probably came on because your O2 sensors are both shot from the excessive oil and coolant baking onto them!

Overheating and grinding noises


First thing you need to do is zero in on where the coolant is leaking out,and where oil is going. Sure sounding like a head gasket, or worse. What engine& mileage?

I have a 2001 grand am v6 that I have to add coolant every few days. The engine is running a normal temp, and the cooling fans are working.


There are only 3 possibilities:
1) Coolant is leaking on the ground - puddle under the car.
2) Coolant is leaking into the engine crankcase - engine oil is "milky" looking.
3) Coolant is burned during combustion process - defective head gasket or intake gasket.
Let me know what you find and we will go from there.
