Cooling problem....Oil problem?
What's up all? this happened to me this weekend, is very interesting and part frustrating... i drove about 350 miles to my friends house to spend the weekend there, the last day there i went to get the oil changed, i did it all my-self (no brainer) and i fould that the oil inside of the oil filter was a bit mixed with fuel! is this ok or what's the big picture? that did not have me as much intrigued as what happened later. I was driving to my friends home and the coolant light when on. I stopped by auto zone bought a gallon of antifreeze and added some... the reservior was good, it was not low, i waited for the car to coold and then proceeded to add some through the radiator. I thougth that was it, but it wasn't. As i started my journey back (305mi), the buzzard went of again and it was indicating that i needed to add more coolant to the car!... i pulled over and opened the radiator cap and it was pressured and everything seemed ok. I turned around as a precaution and went back to my buddy hoome and we were trying to figure out what could be the problem.
1.-The water pump could not have been it because the car did not over heat at any time.
2.-There were not any visible leaks anywhere around the engine and after we moved the car we inspected to see any antifreezed on the floor and there was none.
3.- What he found was that on the top of the radiator, the sensor that starts the buzzard when the radiator is lown on coolant was a little loose, we carfully tightened it back and thought that was going to be it.
That did not solve the problem and the thing is till going off. My car is not over heating, and this morning i might have added less than a half-cup of coolant, but still that should not be a reason why it should be going off... any suggestions comments...

flow problem with the thermostat? I changed the thermostat in my wife's beamer and the thing was broken, the thermostat sping was sticking out the side and the therm was about half open. Who knows how long that could have been that way. Its worth replacing if its been awhile. Cheap right?

Perhaps the sensor in the radiator is defective, or you've got a little air in the system. Have you removed the air bleed plug? (while the engine is cold, of course.) It's the little black plastic plug on the passenger's side of the rad, near the top radiator hose connection.

You're loosing coolant somewhere, you just have not found it yet.
When you stop the engine, smell for coolant steam at the cowl near the hood hinge.
If you have an external leak, it will tend to concentrate the steam there.
One common leak that's hard to find is the 3/8" coolant hose that runs from the back of the TB, down under the UIM and into the top of the rear iron.

By the way how do you know if the cap of the radiator is messed up?

You can tell if the cap is fucked if the seal is chewed or worn in any way. this is only really applicable if you have the style in wich the return hose is connected to your filler neck. If there is no seal, when coolant is pressurized, it will just leak right out the return pipe back into the resevoir.
Fuel in your oil is ok actually. Its blowby from the engine itself. During the compression stroke, small amounts of fuel seap past the seals into the channeling oil, over time it collects I suppose. Thats another reason for the PCV system I believe, to vent that extra gas out so it doesn't collect and build pressure in the oil pan, causing a leak on the gasket supposedly.

i bought a cap and that didn't solve the problem, what i did next was that while the engine was cold i added coolant to satisfy the need, then i started the engine and saw the coolant go inside the hose, i added some more and then the radiator was full... i accelerated the engine and as the coolant went in i added more and as the engine slowed down some of it was coming back so i accelerated more, added more coolant and put the radiator cap in place... this my friends solve the problem... what i think i had was the thermostat i think? what do you guys think?
