Is one injector spraying way too much fuel and causing it to leak into sump past piston rings?

Posted on Dec 09, 2014

Testimonial: "there is no excessive smoke from it is there any seals in injector pump that could put fuel into oil"

  • Bryan Smith Dec 10, 2014

    The file pump is normally inside of the fuel tank. Even if not, the pump can't leak fuel into the oil sump. If you didn't have fuel injection, and had a mechanical pump, then yes, a manual fuel pump can leak fuel into the oil.

I have a 2000 hyundai grandeurmy car idle rough, had duel injecters cleaned but it's still the same. now its sluggish when you take off and they say its a problem with a one cylinder is not working they...

If it is not firing on one cylinder, check and eventually replace distributor rotor, or electronic injection module.
Check also for camshaft problems.

Blue smoke coming out of exhaust

Colors are usually as follows.
White = water/steam, often indicating a blown head gasket.
Black = fuel (gasoline) rare these days because of fuel injection. ( Also black) can be worn diesel engine
Blue = oil smoke. Old days often was worn oil ring on the pistons; today, more often worn valve stem oil seals. Many cars can have those seals changed without removing the cylinder heads.
God bless your efforts.

My 3406b caterpillar engine is having excessively high oil levels

Time to find out why your oil level is going up.
Either coolant in the oil, or fuel in the oil.
Which ever it is the cat engine is not happy. My suggestion would be to get an oil sample test.
Any major diesel repair place will help. Just a little oil in a sterile jar to be analyzed for contaminants.
Coolant is the worst as it will scour the bearings.
Good thing you are concerned.

Won't idle properly, smokes, does not shift right

Black smoke is usually too much fuel to the engine. Check main computer that controls fuel injection and timing.
Blue smoke is usually oil getting sucked past worn piston rings or valve seals.
White smoke = water getting into cylinders, bad head or intake manafold gasket, or cracked cylinder head or engine block.

2003 GMC Duramax Diesel won't start

I see that you had the injectors replaced 20,000 miles ago. I would still check the oil to make sure it is not overfull. The new injectors could be bad. If the oil level is not overfull then get a paper towel and touch the dip stick tip on the paper towel while oil is on the dip stick. If it's only oil it will not spread. If it has diesel in the oil the oil with spread. If this test doesn't show the injectors to be bad then you have three other possibilities. The FICM (fuel injection control module), the fuel pressure regulator, or the injection pump. It's hard to pinpoint what the problem is without running more tests and the only way to run those tests is with the computer the dealership has. Just so you know your injectors are still under warranty until 100,000 miles. Most likely you will have to take it to the dealership to get you truck fixed. I hope this helps you some.
