2003 ford ranger 4.0 2 wd has raw fuel leaking from exhaust


This is usually due to a defective fuel injector. If the injector stays open, once the vehicle is shut off, all the remaining pressure in the fuel system will drain fuel through the injector, fill the cylinder, and overflow through the exhaust valve into the exhaust lines. The downside is that this injector could also be causing fuel to get into the engine oil by leaking around the piston rings. This will greatly reduce the oil's ability to lubricate and increase engine wear immensely. This issue needs repaired ASAP. Have the injectors checked, and any defective ones replaced. Have the oil and oil filter changed as a precaution as well.

2001 izuzu tropper 3000 wont start... Injectors replaced, 12V ok on the injectors, Can it be anything related with the oil pressure on the rail (injectors)?


oil viscosity is very important, and yes if the rail oil pressure sensor is not reading correctly at least 3 to 5 Mpa while cranking the injectors will not be turned on by the engine ecu. if you can get a scan tool look at rail oil pressure sensor reading just after cranking it should drop to 0 to 0.5 Mpa if any different its no good, also check for oil leaking out of main injector harness connector near engine oil dip stick if oil leaking out of connector this pressure switch which is in oil rail under rocker cover is no good and injector harness needs replacing this is very common.

Would a quart extra of oil fowl the plugs or plug the injectors


I am not certain that an extra quart of oil would give you the problems that you are asking about, but overfilling your crankcase does increase the pressure inside the crankcase and may force oil where it shouldn't be going. In particular, your EGR system might start sucking up much more oil vapor or even liquid oil and mixing it back into the fuel stream going into your engine. I have had carbureted vehicles with tired engines (i.e., a lot of blow-by and oil vapor in the head) where the plugs have fouled because I have drawn too much oil vapor into the fuel system--in those systems, the EGR valve fed back into the air box, so the air being drawn in to mix with gasoline was laden with a lot of oil vapor. That fouled the spark plugs quite nicely, and I'd have to change or at least clean the plugs after a while to keep the engine running properly.

I am less persuaded that excess oil vapor can plug your fuel injectors. The injectors are designed to squirt a precise amount of gasoline into the air that's being drawn into the engine. The "oily air" would never be on the high pressure side of the fuel injectors. I suppose it's possible that oil could be deposited on the outside of the fuel injector in such quantities that the injector wouldn't spray in a proper pattern, reducing engine performance. However, the fix for that would be pretty simple: remove the fuel injector and carefully clean the outside of the injector with a serious gum-cutter like Berkebile 2+2 (which is much more potent than standard carb cleaner). That fix would be both faster and cheaper than disassembling the injectors to clean their internal parts.

There is oil in the number one fuel injecter, what could be causing this?


A number of reasons can cause this. worn piston rings, bad valve seal or oil coming from outside injector with bad o-ring. The fuel injector is not your problem because oil does not flow through your injectors. how do you know you have oil in your injector? Talk to me need more info
