    My car runs good at times and then I can run it for a longer distance.Turn off want start until cool.
    168,000mi New coil,plugs,wires,battery good.It runs better in cold weather. Had it checked showed code:P0322 Could it be the crank position sensor?

    What causes condensation in the oil and how do i get rid of and stop it?
    Gooey substance on oil cap and dip stick. Mechanics have found it on my crank sensor. I had the oil changed and the engine flushed about 2 months ago and it is back again.

      If the substance is a gooey, milky color - this should be condensation emulsification. The condition occurs when the engine regularly does not warm sufficiently to evaporate off initial condensation forming on cold internal surfaces - and previous condensation.
      It tends to form and remain on colder part of the engine not fully immersed in oil (like rocker covers and tops of reservoirs) sooner than in the circulating oil itself.

      A standard type automotive engine needs between 10 and 20 miles (close to continuous operation time) to get all parts to optimum working temperature - which evaporates the condensation from the internal engine surfaces.
      As example, this is one reason why highway miles are generally easier on an engine in terms of service life (longevity in years or time) than short distances - with all other factors equal, such as maintenance intervals, type, grade and quality of oil and filter.

      As long as the engine sealing integrity is OK - check the integrity with a cylinder head leakdown and comporession test. The condensation and oil condition noted now may be the early stage of a cylinder head gasket leak.

      Since I don't drive 10-20 miles a day, is there a oil additive that would help with the condensation?

    Why am I getting condensation in my oil and how do I stop it?
    Gooey build up on oil cap and dip stick. Mechanics have even found it on my crank sensor that went out recently.

    What does this plug go to?
    i have a plug right near my starter that has a white wire with a red line and a black line where does it go?

      If there are no symptoms you are trying to correct leave it be. There are often a few wires or connectors on cars not hooked up for other optional things that your car was not built with too numerous to mention.

      would crankshaft sensor make my car shutdown at 160 degrees and take a half hr to start back up?
    • HouseCallAuto
      4/5/2014 HouseCallAuto
      yes. as a matter of fact I have a client with a 2001 Jetta right now that needs a crank sensor. car stalled while driving no warning, no spark, no start. Different than what you have but still very likely. Plug in a code reader and see what fault codes are stored. You cannot skip checking for codes. My clients Jetta had a P0725 fault code which = "engine speed sensor" fault, which is a crank sensor with the European name.

      So this is a definite bad crank sensor.

      could it also be a faulty fuel pump or would the faulty fuel pump make it not start at all?
      AutoMD Member
      4/5/2014 HouseCallAuto
      There are certain rules and protocol to follow. When you have a no start ON ANY CAR and this is accompanied by a crankshaft position sensor fault code stored in memory, you do not do anything else except replace the crank sensor. Change the sensor, forget the fuel pump for now.

      well the end of the sensor broke off in my block what can i do to get it out? a self taper and pliers?
      AutoMD Member
      4/7/2014 HouseCallAuto
      That was not good at all to break off the sensor. If you cannot figure out a way to extract it then you will be removing the oil pan in order to get on the other side of the sensor and push it out from inside.

      will putting green antifreeze in my jetta affect it any?
      AutoMD Member

      Yes it will cause you to make Jello in your cooling system. Only use coolant that meets V W specs. the coolant is definitely not green.

    Theres excessive white smoke coming from my exhaust and a noise from under my hood whats wrong.
    i have 2003 VW jetta wolfsberg edition with 144x miles on it.i recently had my wheelbearings done& as i left the garage i noticed a noise coming from under the hood that was never there before.i had it looked at again &was told the oil just needed to be changed.once ...

      When someone says there is white smoke coming from the tailpipe of the exhaust system (confirm this is where it is coming out of) this always means a head gasket problem but something tells me that you might not have white smoke coming out the tailpipe, but more like "smoke" coming from under the car because of some liquid leaking on to the hot exhaust pipe someplace - (burning smell) or maybe you are right and if indeed there is white smoke coming out the tailpipe and you have a power loss then maybe the head gasket is no good. To notice this on the way home after a wheel bearing rplacement is kind of odd. Need more info.

      i thought it could be the head gasket too but theres none of the other norms like the sweet smell or milky oil. so im not sure if thats it. but the smoke is definitely coming from the tailpipe and is worse when i stop at stop signs or lights and then go again. but i also noticed the car getting hotter faster then normal but there is no coolant leaking from reservoir or anywhere else that i can see. so im stumped and dont want to take it back to the garage since i think they might have caused it

    Best synthetic oil brand for a 2007 Jetta (SAE 5W-40, 30)?
    Looking to learn more about cars, mine in particular for maintenance and understanding.
     
    • Jimm

      No real clear cut 'best' in terms of brands - any quality name brand engine oil of the recommended viscosity and grade with the current API (American Petroleum Institute) letter SN, SQ etc. designation. Reference the vehicle owners manual as the first step for the oil recommendation.
      The formulation of engine oil may be either synthetic, semi-synthetic, or mineral based - each type has its benefits and drawbacks. There is not a one-size-fits all oil on the market for all engines or vehicles.

      There are many on-line and free automotive basics for maintenance and understanding; www.AutoMD.com and the 'How-To-Guides' feature, the website www.autozone.com, www.carbibles.com, www.bobistheoilguy.com - to list only a few resources.

      Certainly, the local public library in your area and the auto reference materials section - all these are good places to start. Remember, every master technician has gone through the basics at some point. No one is born an expert.

    188,000 miles I start to take out AC compressor. I loose 2 pipes and the 5 inch long bolt. The compressor is not loose. Only the belt holds it tight? Have other bolts that hold it?

      The issue seems to be related to the low fuel pressure - faulty fuel pressure regulator, faulty fuel pump.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the fuel pump from around $35.00 and the fuel pressure regulator from around $33.00 for your vehicle.

    65,000 miles. Firsti was told there was carbon build up in the intake valves and it needed cleaning ($650). Then another shop said I only needed a tune up and tochange the spark plugs and ignition coils ($550). Did the spark plug/coil change and light is still ...

      Taken for a ride? Possibly. How is it these different repair shops are allowed to throw money (yours) at the problem without your understanding of the issue and the specific fault code definition?

      Try this as the next step - free of charge. Have the specific fault codes scanned - for free - at any local auto parts store. Then post a reply with these codes for further assistance. Do this step before spending one more penny.

    Is there any way to extend the life of valve cover gaskets, cam shaft gaskets, etc. on the 2002 VW Passat?
    The car has 177,000 miles on it and I've had new valve cover gasket kits installed 4 times (since new) and now am being told I'll need them replaced again soon. Is that excessive or about the norm?
     
    • Jimm
      3/11/2014 Jimm
      No real method to determine nor extend the gaskets service life. Many factors dictate the gasket replacement intervals; underhood temperature, previous installation procedure, gasket tightening torque (too tight can drastically reduce gasket effectiveness) and exposure to chemicals.

      Generally, as long as the gaskets are OEM (original) quality or better and have been installed correctly - proper torque and not overtightened - then you can expect maximum life.

      Always use the correct and best gaskets affordable for the application. Stick with proven brand names; Victor, Fel-Pro, Beck Arnley. The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the valve cover gasket set from around $27.00 for your vehicle.

    I am not getting gas
    154000 miles the fuel pump will not run how do ii check it and replace it
     
    • Jimm
      3/9/2014 Jimm
      The fuel pump should run as soon as the ignition key switch is turned 'on'. The fuel pump energizes to pressureize the fuel system in order to feed fuel to the engine.

      If this initial pump sound is not heard - suspect the following; faulty fuel pump relay, faulty fuel pump wiring / connection, faulty fuel pump.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the fuel pump (in tank) from around $27.00 for your vehicle - depending upon the build date.
      The fuel pump is removed from the top of the fuel tank - accessed through the trunk inner panel underneath the trunk floor. A round, sheet metal plate beneath the trunk floor carpet on the passenger side provides the access point for the fuel pump. It is secured with three Phillips-head screws.

      If you need directions / instructions for the replacement, use these websites; www.autozone.com, www.pelicanparts.com, or www.AutoMD.com and the 'How-To-Guides' feature.
