Blown Head Gasket?

stic-o · #1 10-28-2009, 11:56 PM

This is relation to my 2005 F150 w/5.4 3v. 59k miles

On the way home from off-roading (towing the off-roader) we started getting a chugging sound from the engine on the passenger side of the truck. It could also be a exhuast leak, but you only here it under load, or when the truck is in gear moving. We were pushing it a bit hard coming home on a hill ( blowing past all the diesels

) but I didn't think that bad. I'm also running a edge Programer so the good thing is it records all the tempeture peaks.

I don't think these are high enough temp to cause this problem. These are all peaks. So they were not there very long.

ECT 212* (Coolant)
EOT 243* (Oil)
CHT 224* (Head)
Trans 214* (it stays under 200* most of the time)

I have no power loss, and the oil looks fine, although a bit dirty already for just being changed 1000 miles ago. Also the no dummy lights or codes were triggered.

Thoughts?

CEL ever come on? Engine oil level stay relatively constant? Was that the only time it made the noise? If you've got no loss of power, no codes and everything else seems fine, no idea what that 'chugging' sound could be.

You sure it wasn't a pinging from pre-detonation?

Probably NOT a head gasket.Could be exhaust leak or a valve train problem..

Can't pin down the problem, So I'm going to take it over to Ford and let them figure it out for $100 bucks

Other wise I could just replace part till the end of time.

really have no idea sense it dosn't throw any codes. If you had the stereo on, you would not even know there was a problem.

I hope you didn't accidently have a performance program running with mostly low octane fuel.

Im having the same problem, how much did it cost to fix? Ford dealer told me 500 just to tear it apart and look at the problem.....but he said it was the valves being starved for oil and to see if I have burned the valves.....

I describe exactly the same issue....can that be a major problem?
