petrol and engine oil are mixing

The petrol and engine oil are mixing, what could be the cause of this? fuel is mixing whit the oil already change the fuel pump Your problem is going to be an injector(s) or injector O-rings. Fuel can leak out of the solenoid of the injector into the oil, or the injector o-rings can leak into the oil also.  You will need to bypass the fuel filter, add some clean fuel in a bucket, add some fuel/oil dye to the fuel, and run the truck off of the bucket of fuel. Take the return off of the back of the head, and also run this into the same bucket, let it run for a little while off of this fuel, remove the valve cover, jake housings(if equipped) and rocker arms, take a black light, the dye will glow where the fuel is coming from. I would not rule out an injector, I have seen it more than once, but the most common is injector O-rings. You should have 3 o-rings, they should be pretty close to the same size. It is also recommended that you replace the hold-down b...

2005 Nissan Murano where is the filler plug for transfer case?

Transfer case Filler Plug Location 2005 Nissan Murano sl 3.5 front wheel drive. where is the filler plug for transfer case? If it's front wheel drive only and not AWD, you need to add CVT fluid to the transmission. I strongly recommend you get the fluid at the dealer. Transmission fluid is added through the dipstick tube. the "drain plug is 10mm hex key, filler plug is 12mm box wrench".

OBD 1605

Nissan Altima OBD code 1605 P1605 NISSAN - Automatic Transmission Communication The 1605 code for your year Altima is either due to a weak battery or a bad AT control unit. Weak battery - Faulty Transmission Control Module (TCM) - Harness is open or shorted between TCM and Engine Control Module (ECM) - Poor circuit electrical connection between TCM and ECM Here is the steps to check the system out yourself. https://dl.dropboxusercontent.com/u/105565483/1d.pdf If the transmission seems to function fine,then it is more likely to be either a weak battery or an opened or shorted communication line between the ECM and the A/T control unit? Malfunction is detected when an incorrect signal from Transmission control module (TCM) is sent to Engine Control Module (ECM). I would start by clearing the code and see if it returns. If it does, I would check the battery and the charging system voltage before replacing a control unit or getting crazy about checking wiring. Thi...

coolant over flow

coolant over flow  I just filled  coolant over flow area all the way up, Now what to do? Solution: Its ok that you filled it up. If the engine is low it will take some of the antifreeze out of the overflow as needed. You may see some on the ground because when the engine cools it can put it back into the overflow. You aren't going to damage anything by doing this. If it still concerns you, you can adjust the level by using a turkey baster to pull some of the extra out of the overflow. Coolant Temperature Sensor Operation: This sensor monitors the temperature of the engine and sends that information to the engine control computer to regulate the amount of fuel needed. More fuel is needed if the engine is cold; less if it's hot. If the temperature is extreme, the signal will be sent to the temperature gauge as a visual indicator of overheating and imminent danger. Inspect the sensor's wires and connections. ECT (engine coolant temperature) sensor ...

Auto lock system / alarm going off, car wont start

Auto lock system / alarm going off, car wont start Nissan 02 altima Its the factory auto door lock & alarm system,when I use the key chain lock/unlock its stooped working so when I use the key to open the door, the alarm go's off. I somehow got the horn to stop but now it won't start at all I think that the car's computer has shut down the stater as It's anit-theft mec. The vehicle wiil not start ! The alarm was activated, And I tried to turn it off by starting the vehicle, and now it won't start ! Nissan did not come out with auto lock till 2010. So if your doors auto lock, then the after market alarm is keeping the truck from starting. Try this solution:---- Lets first do this and set the alarm and turn it off to make sure that isn't what is causing your problem. Do not use the remote, use the key. Open the drivers window. Lock all the doors from the out side using the key at the drivers door. The security light should turn solid for abou...

Ford lose power while driving uphills

car lose power while driving uphills If the engine is running on all cylinders, runs fairly good overall but loses power on inclines or hills. I really have to lean to a possible blocked cat converter or one becoming blocked. The " honeycomb" material inside will break down over time and when it does, its causes a partial blockage, engine cant breathe and normally noticed under load lik up a hill but in most cases run ok otherwise. There is a tool to check back-pressure on each side of the cat converter to confirm but without one, I can only lean to one becoming blocked. In your case one would have to remove the cat, road test and if ok, then replace the converter. Due to age and miles, this is very possible the problem. they do degrade over time. Another possibility bad gas can cause this, Most vehicles are hard to rid of old gas but I am fairly sure yours has a drain plug on the fuel tank. I would drain it, add good gas, maybe an additive and run it for a bit. It ...
