I have a 2002 Nissan Altima 2.5L. When i drive more than 11 miles, it sound like the timing chain is rattlling inside the engine. But if i stop and shut the car off for like ten minutes then the rattling...


Hello this issue could be caused by a number of things I know on the 3.5 engine there is a timing chain tensioner that sometimes slips down and the rod that makes tenison on the chain gets fully extended and the chain will be sloppy.Also on the 2.5 the catalytic converter
can come apart and cause problems for the engine.This rattle can be as simple as a loose exhaust heat shield hard to say with out hearing the noise.One other problem I have read about with those 2.5s is sometimes the butterfly valve screws come loose and could get sucked into the motor.You can go to Youtube and see all these things that I have mentioned good luck.

Oil light keeps flashing, car full of oil


Low oil pressure could be the reason the oil light in your car will come on. Test your oil pressure. Without enough pressure, the oil will not reach necessary areas of the engine. The oil pressure sensor itself may sometimes become clogged with sludge from the engine, especially if the engine has not been properly maintained. A clogged oil sensor can give a false reading of low oil pressure, which will illuminate your oil light. So, check the oil pressure sensor light.

I have a 97 Plymouth Voyager 3.0 engine the oil light comes on and keeps dinging for about an hour first thing in the morning and sometimes later would like to know how to fix or at the very least dis


first of all check the oil level in your engine. If is ok,then check whether the oil filter is a correct one . Change the oil filter with the correct filter and follow it for a day and if the problem gone means that the filter was not keeping the oil in a correct quantity and pressure.Also check if the oil pressure is a good one and it keeps working accurately. A simple try as a test but not for long is to disconnect the cable and follow it if there is not any warning comes on then change the oil switch.

1999 Mercury Cougar Starts and then Shuts down. In the beginning the car had a rattle in the TimingChain cover and was checked and it was fine, just that the Oil pressure was low and then the lifters...


Most engines have a low pressure shut-off OR the lifters no longer work with lack of oil.
Have someone check the REAL oil pressure with a gauge.They can thread a gauge into the Oil pressure sensor hole.
Since the oil pressure sender COULD be bad,you need this true reading.
It should run just long enough to give a reading,I hope.
I don't know if the OBD II codes would show the oil pressure.UIt doesn't on my Focus.I hope you get `er going,but the engine must have at least 25 psi oil pressure.Have you replaced the oil filter? don-ohio

Check if the engine is over heating, such as the thermostat. But don't forget to check that the heat riser opens on the exhaust manifold. In general, popping is either too lean or bad timing. Check for vacuum buildup in gas tank by listening for whoosh when you open cap. Check for vacuum leak with vacuum gauge attached to manifold. Check for plugged catalytic converter if the old motor was dumping oil, by attaching pressure gauge to oxygen sensor port. Check timing. See if power loss is all cylinders or just one, by removing plug wires one at a time. Finally, check oxygen sensor with ohmmeter (sorry I don't know the expected reading.)
