Bad Head Gasket??

OK so today i noticed a rattling noise coming from my engine. At first i thought maybe it was a bad pulley, but after further investagation i found that my oil cap had a milky substance on it and the coolant in the resivior isnt as green as it should be. However i dont have any white smoke coming out the talepipe and i havent had any problems with it overheating. The truck only has 47,000 miles on it could it have blown a head gasket already.

White in the oil is water. Now look for some other clues.

Is the oil level higher than when you last checked it? If it is then that's not good.

Otherwise if a motor is started up and driven only a few minutes. That too can cause moisture.. but is normal.

I say change the oil and then keep an eagle eye on the fluid levels.

Oil level was the same.

As for my driving habits. My ride to and from work is only like 3 miles.

I plan on changing oil tomorrow. I will definately keep a close eye on it after the oil change.

what you can do just to see is make sure there's no pressure on your cooling system, and open the radiator/coolant jug cap. start the truck, and put your hand over the opening, if exhaust is being pushed in the cooling system, you should feel either a slight vacuum, or slight pressure. the way we do it at work is pressure the cooling system up with a press. tester and start the vehicle, if its a head gasket it will almost always make the pressure start going up on the tester... its worth a shot?

Yea, like Rich said.... Since you're only driving short distances, that could just be moisture. I doubt you have a blown head gasket already. You have like the cleanest, most well maintained vehicle on here. lol

Well i changed the oil today, there was no signs of coolant or water in the oil.

But the rattling noise still hasnt gone away, it seems the higher my rpms the worse the sound gets.

If the rattle is between 2300 & 3000 RPM's, it sounds like the timing chain tensioners to me! If you only drive 3 miles to work, the engine isn't getting hot enough to burn off the condensation.

I know it has the timing chain rattle, but i cant figure out where the other rattle is coming from I stays constant with the rpms and does it in idle, in gear, and with the clutch depressed. and it sounds like its coming from the bottom end of the motor.
