SOURCE: engine blowing oil from oil filler cap

I had the same problem. I changed the pcv valve and checked the hose. It still did the same thing. Then I checked the metal tubing that the hose connects to and found it was full of hardened gunk. I sprayed PB Blaster into the tube let it soak for awhile. Then took an old choke cable, put it on a drill and ran it into the tube like a drain snake. It took a while of doing this over and over but eventually got it cleared out. Now, no more oil all over the engine and hood compartment.

SOURCE: trouble code po456 evap small leak ? could it be the gas cap ?

Can't say 100% obviously, but quite often that is the cure, but try to take some time to make sure all your hoses , in the system are in good shape & tight.

SOURCE: my camry's check engine light came on and the

The EVAP system on OBD-II equipped vehicles is monitored by the computer. When the gas cap is bad, or if there is a break in the system somewhere, this alerts the computer (ECU) of a problem and the ECU will turn on the check engine light to alert you of a problem. Although not normal, it is something that can happen and need replacement. You can inspect the filler neck yourself for visible damage (it is the flexible/ribbed hose going into your fuel tank from the filler) and replace the gas cap yourself. i might suggest replacing the gas cap and then having an Auto Zone or Napa reset your computer to see if the cap was the extent of the problem before i paid a shop to replace the filler neck. If the cap was specified as a problem, you really have nothing to lose on pursuing this fix first. Also, if you can order the filler neck, this is a relatively easy replacement and requires only shadetree mechanic skills.

i hope this helps,
matthew

white smoke out the tailpipe and the smell of anti-freeze in the exhaust gas. an engine that over heats either only at highway speeds or town driving, when all other things like, rad cooling fan working properly, thermostat is working properly, no external coolant leaks. the spark plugs may show signs of coolant on them. just some things that are indicators.

Smog check hc


check the cat. and the sensor/s on the exhaust pipe. change air filter and plugs clean out the intake. and check the EGR valve. there the main problems with an emissions fail. failing that check oil and water look for water in the oil (filler cap has white film on the inside). water look for a shiny oil mark. in still water. if any of them or both then that could be you problem head gasket has failed.

Oil coming from bottom of 1996 ford contour. No leak from the motor


If you have recently had your oil changed,the oil filter may be loose or cross threaded.Also if you have had an oil change recently it could just be spilled oil. Make sure your oil filler cap is on tight and the dipstick is on tight. While you are at it check to see how much oil you have actually lost.If it`s not coming from the engine,i would inspect the oil pan gasket and the oil pan itself may have a hole in it.

2007 subaru forester: why is check engine light on?


The CEL and Cruise blinking is the error indication. Could be any of several issues.
1. The gas cap is loose, or leaking. This is a VERY common error and is written up in the owners manual. The fuel filler neck could have a leak or rust hole.

2. A small exhaust leak on the "donut" gasket in front of the catalytic converter can cause a"cat inefficiency error", fixable by replacing the donut. For an '07, it unlike that the $200+ fuel/air O2 sensor or the cat needs replacing.

1990 regal starts, runs for 2 to 3 min then dies, changed fuel filter, crank sensor, coil packs, it has 45 pounds of prs. to rail. im stumped


hi, please check you oil level, ( on level ground). when the car is running place an old rag in front of you and take off the oil filler cap (be careful not to get near the fan, fan belt) if no oil comes out of the filler hole possible fault: oil pick-up pipe (in sump partial block), / oil filter in sump ( blocked), oil pump worn, oil relief valve (returning oil back into the sump), spring weak / broken. the (E C U) ENGINE CONTROL UNIT has many sensors that can stop the engine: but try cleaning the (EGR) ENGINE GAS RECIRCLING VALVE, this valve recycles gas back in to the engine, ( must be CLEANED with BRAKE FLUID) this is a VERY DIRTY job, as this gets block with carbon (EXHAUST PARTICULES). the E C U will detect all of these sensors: the (ECT), TOP OF ENGINE engine coolant temperature sensor rough tick over, (HO2), EXHAUST DOWN PIPE, heated oxygen sensor checks mixture of fuel, can adjust air / fuel, it tries to keep car going / may flood engine. (M A F) mass air flow, adjusts fuel / air retio this sensor can so much fuel to the engine it may flood it. flooded engine mean WET spark plugs. i would put it on dianostic machine to check these out before paying for extra sensors. gerry
