May have radiator fluid in oil 2001 vw beetle


An oil leak mixing with coolant is an internal leak, which is usually the result of a faulty or damaged head gasket, or cracked head. This is a major repair job, because the entire top of the engine has to be removed to do the repair. You can't see the leak because it's inside the engine, not outside of it. White smoke (steam) should be coming out of the exhaust pipe if this is true.

Smoke smells when ac on nissan sentra


The speed control of your fan has resisters that are in the venting system to blow air on them to keep them cool. If they overheat and or burn you will lose your low and medium speeds of the fan. If you run the fan at full see if the smell goes away. Your engine could be burning oil on the outside of the engine block, make sure that the weatherstrip where your hood meets the fresh air intake grill is sealing tight.

Nissan maxima 2000. Oil dipstick level shows too high. Regular oil changes done and filter with proper amount added. White smoke alerted me to recheck things. Only thing I found was dipstick shows oil


If the oil level goes up, something has to be leaking into the engine oil pan.
That would either be gasoline from the injectors or coolant from the radiator. If you are not adding coolant, it could be a leaking injector.

MY 2001 ford escort se has oil in my radiator and water in my oil...No smoke but there is a little steam,A loud knocking is comming from under my valve cover.Please tell me i might not have to rebuild or...


There was a head gasket problem and some water goes to the piston head. It is wise to open the engine and let the machine shop engr. to do the total cost estimate to rebuild it. Cost including the parts and labor of the mechanic who assemble the engine. If the total cost of rebuilt is cheaper then let it be done by the mechanic. Option 2 is to find a second hand engine from surplus dealer and have a cost comparison.

The engine is making a really loud knocking noise and the oil light is on. it also smells like something is burning or running hot


Doesn't sound good. Check oil level. Also check for metal in the oil once you pull the dipstick. A loud knocking noise is a sign of a blown engine may be you spun a rod in which case you would need engine replacement or rebuild

Audi 1.8T sport Auto (2001) heavy smoke and engine buring smell


The engine could be shot, oil is being burnt off by the actions of being sucked into the bores via worn piston rings then ejected out of the exhaust

If you sent the car in for an MOT and a Service I would ask the garage what they did to it as the car would have failed on its emissions test if that much oil was coming out .

It could have been a fault on the oil pump or lack of oil in the first instance and maybe an overfill on the service

You paid your money now go back for redress

MY 2000 MAXIMA IS HAVING LOTS OF ISSUES


Your antifreese is leaking through the engine block The white smoke that you see coming out off the tail pipe is steam from heating up the antifreeze. This problem needs to be taken to a mechanic because your engine may have a blown head gasket or a cracked block. You keep having to fill it up with antifreeze because it is evaporating inside your engine block. Check your oil and see if the color is like a white milky liquid. If so then its definitely your head gasket. Try not to run the car to much like this because you will crack the engine. This is a pretty expensive job. You may want to consider a different vehicle because who knows what else will go wrong with this vehicle. I hope this helps you.
