Check for a vacuum leak. If no leak prob. a bad O2 sensor. (Gas in my oil)?

 

My oil is very thin and smells like straight gas.. thing that posses me off just changed my.oil yesterday

 

check and see is a rock or something went thru your intercooler. or your map sensor could be bad.

 

Found this on the net. Take it to the dealer might have a major problem


If a large amount of gasoline does get into the engine oil, change the oil immediately upon fixing the problem that has allowed this to happen.

Excessive Fuel
When a fuel injector is stuck open, the fuel will flood out. Gasoline will definitely get into the oil when this is the case.

If the fuel pressure in your car is too high that may cause gasoline to get into the engine oil

An inoperative injector system can also cause this problem, because if the engine is not firing appropriately, the gasoline will end up running down the walls of the cylinders.

Check to see if the float in the gas tank is rising the way it should be rising or if it needs an adjustment. You will not be able to look at your gas gauge and get an accurate reading If the float is not functioning properly.

Your engine may be running rich, with too much gas going into the engine and too little air.

Check to see if the oil level might be really high. This can also cause trouble.

Check Piston Rings First
Any time you realize that too much gas is getting into your engine oil, you should replace the piston rings and then replace the oil. See if this helps the problem, and if it does not, then investigate the many other possibilities as to why the fuel is leaking into the oil.

Perhaps at this point do a compression test. Otherwise you can try getting your fuel injectors tested. Also check your spark plugs to see if they are good or if they might be misfiring.

 

if your oil smells like gas do a compression test, you got a ring that let go dude sorry

 

Well oil will smell like gas naturally. I'd say find what's causing the lean condition first then go from there

 

ehh, you could always send a sample to blackstone

 

It's turbo charged and also there is natural blowby occurring at all times. Go smell your oil real quick

 

moot point my car has very low miles, he said it was "thin" and smelled like straight gas after one day, I still maintain a compression test is in order, I've been wrong before but its easy to compression test
EDIT: you do have a valid point though; if his O2 is bad and his ECU is dumping fuel you could be right

 

Just saying that to assume piston rings immediately is absurd especially with a lean code. It may be adding fuel to compensate for the lean condition. Is it multiplicative? When is the condition being recognized as lean? Lots of variables

 

Thanks guys headed to the dealer tonight... I'll let everyone know...

 

If I had a vacuum leak wouldn't that mean it should not build full boost. That's why it had me stumped good oil pressure and temp perfect boost. And still lean code.. I was lost. Thanks for the ideas.

 

If it's a leak on the pressure side causing lean condition you might see less boost or hear an audible leak but it will probably just keep te gate actuated to spool more to meet requested boost values. Vaccum is not on the boost side as it's called vacuum . It could be a hose anywhere on the engine which an engine is a vaccum pump and our car probably has a cam driven vacuum pump. Not familiar enough to be for sure but I bet it does.

 

Fuel injector pump is what ford is saying

 

This is the third HPFP that I've read about is this correct?
