Got the chocolate milk in my oil, 2000 F150, with a 5.4 Liter. head gaskets or intake gaskets?
And what is the best way to determine what is leaking? Thanks
And is there a good product for flushing the engine?

 

Its always best to start with the cheap stuff first so I recommend the intake manifold gasket before the head gasket job, and as for Oil System Flush I recommend VS7 oil system cleaner, all you have to do is add it into the oil, start the engine for 5 minutes, leave it idling then shut it off and change the oil. I'm not a certified mechanic but yeah I tried to give the best advice possible lol.

 

Head gasket or a cracked block.

 

First off a couple of questions. Did you see this on the inside of the oil filler cap or dipstick? or, Did you do an oil change and it came out milky?
If you did an oil change and it came out milky, then you definitely have a leak, if it is just on the oil filler cap or dipstick, it could be simply condensation considering the time of year it is. Do an oil change and if the oil is fine, then you know its condensation.

 

Good point!

 

Thanks

 

It was on the dipstick, and my thoughts are to change oil and filter and see what comes out, and keep an eye on it for a few miles.
I never thought of the weather change issue.
Thanks for a ray of hope!

 

I would think a compression check would confirm a blown head gasket. No?

 

Not really.....A compression test tells you that you have a problem with that particular cylinder but does not tell you why. It could be a bad head gasket, a bad valve or it could be bad rings. There are two things that can tell you if it is the head gasket, one way is to apply compressed air to each cylinder, with both valves closed, if you hear air escape from the intake means bad intake valve, from the exhaust pipe means bad exhaust valve if it bubbles the coolant then bad head gasket, the other way is to buy the test kit that checks for exhaust gasses in the cooling system.
