well if you blew a head gasket save up for that new motor... you could also try car-part.com get a used motor... i did that when i got my 99 with a bad motor

well thanks all i am just about to go and start the troubleshooting process i have a couple buddies(they know what they are doing one is actually a mechanic) coming over and we are going to start work and if necessary the tear down

so first we are gonna do a compression test because i have a lot of pressure in my valve cover and gonna figure that out



why would i need a new motor? head gaskets are pretty much an every day fix and people dont need the new motor
and plus if i did throw something hopefully i can get the block bored and honed

that condensation is normal on the oil cap exspecailly during cold weather season it is caused by condendation before you go tearing things down you better do some diag i think you will find your head gaskets are fine. if the oil in the crancase is the same color as the cap then yes there is a problem but cap only this is normal....

Diagnosis will be your best bet...
let us know what you find???

I have to agree with mattd17 my 2004 FX4 with the 5.4 V8 , had the same problem because I only drove short distances. I noticed it more when I lived in Indiana and it was winter. I first noticed it when the truck only had 3,000 miles on it, I took it to a personal friend of mine who is a ford mechanic and he told me this is normal with the driving conditions. When I moved to Hawaii and had to driive father for work I never seen the goop again. Oh they said it was condensation.

Hi, How did you determine that the motor was building pressure in the valve covers?

and - as others have said, the goo in the filler cap ( and no doubt in the valve covers too ) is normal in winter...... even if you drive longer distances. I drive 45 min to work and don't do many short trips. I have the goo also.

Is anyone taking bets? I'll wage it's an induction problem. Maybe as simple as the blower drive belt slipping.

Me again,

I forgot to ask, was it pretty cold the day this happened ( well below freezing )?

Was the motor cold - as in first fire-up of the day?

and does the roush charger have an aluminum case?

I live in Kansas and we have had below freezing days all month. I too have the goo but I always drive atleast 20-30 minutes no super short trips. And like you my dipstick is clean. Probably not any help just my $.02 Hope you can save her!!

to answer a majority of the questions i do drive short distanced alot because my town is very small and no it isn't below freezing where i live

here is the update for today i began pulling the spark plugs to look to see if there was oil on them and there was a little oil on all of them and i put them back in and started the truck again and listened to the knocking again and i noticed it sounded like the supercharger so i pulled the supercharger off and apart and nothing at all looked or felt wrong so by discussion of me and 3 other very talented mechanics we decided that that 5.4 would have to come out because anything that is bent or broken would require the motor to be out to fix it to make things easier,so i began taking it out and i have alot to do i have all the cooling system and the intake off.. i took some pictures of my progress

well you loose the bet already lol ive already eliminated that problem
