So Temp1,

What about your oil usage? I refer to the above posts.

I believe the engine is only supposed to have holes to breathe and exhaust through, to put oil in and take it out of, and then eight of questionable strength to put sparkers in. If you have more than that (although they provide you with an indication you have oil pressure), I'd say Ford needs to see you.

Besides, if you get the oil leaks fixed, you can save your old u-trou for more important things.

 

Pushrod,

Its not really as bad as 6 quarts per 3000 miles but at least a couple of quarts per 3000 miles since I have gone to the synthetic Mobil one.

The truck leaked oil when I first bought it (brand new) and I went to a Ford authorized service center where they said they had a tsb about bad heads and would order one. I never heard back from them while my truck was still under warrenty. The service center said the head was on back order and that they would contact me when they could get it. A year went by and I never heard from the. I checked back with them and they said that they could not do anything for me since the truck was now out of warrenty. They said it would cost $1700 to replace the head. I told them I had been unemployed for over a year and could not afford it. I apologized to them for not checking back with them about the head that was supposed to be replaced under warranty when I first checked in with them.

So thats the story, Im screwed!

Thats what I get for only paying $42,000 for the truck...

 

Welllll,

If it were me, and I had some sort of proof that I'd complained about the leaking before the expiration of warranty, I'd go back to the dealer and raise sand!

If you have a service ticket where the leak was listed, you're in!

And, I was told there were bad BLOCKS, not heads in some '99s. You shouldn't be going through any oil, although one qt/1000miles is considered "Normal".

Also, although some will tell you synthetic will leak more than the dino-oil, the truth is that since the synthetic holds its viscosity better, it will resist finding holes longer. Assuming you are running 5W-20 or -30. If you are running 0W-20, you might lose oil.

 

I don't remember what I did or did not have as far as documentation. My wife wanted to move so we moved to a different house whereupon I was laid off and have been unemployed ever since. We were robbed shortly after moving in as we had our stuff stored in our garage. We got screwed over by the insurance company and the crime in this city sucks big time. I don't know where a lot of stuff is anymore since we moved. I kick myself because I figured these people at the Ford authorized service center would take care of me. I know better now. Lesson learned...


I can't remember if it was a head or block, but I think it was aluminum.

 

I just sucked some Seafoam into the brake booster vaccum line and let it set a few minutes. That line sucks it into the engine a lot better than the PCV line. The PCV line tended to kill the engine but the brake booster sucks it right down. I got lots of bluish smoke this time.

 

Ok, before I get too stupid with the seafoam, I sucked half a can which is 8 oz. into the vacuum line with the engine warmed up. I assume the intake manifold and the cylinders are hot and that the seafoam is boiling/bubbling/vaporizing as it is taking into the engine and being evenly distributed between the 8 cylinders (In a perfect world).

Now lets say my engine has not been warmed up and I start sucking in that 8 ounces of seafoam into the vacuum line and it does not pool anywhere in the throttle body or intake manifold and only finds it way into ONE cylinder. 8 ounces is a fair amount of fluid to be putting into ONE cylinder? Does anybody know what the cylinder volume is when the piston is at Top Dead Center? Not that I would suck Seafoam into a cold engine but I wonder how much liquid would cause hydrolock if it all went into ONE cylinder.

My question again is:

What is the volume of ONE cylinder in a 5.4L engine when the piston is at Top Dead Center?

Larry

 

Dunno. Higher math.

Besides, the point is moot. If you engine didn't suddenly start making horrific noises, you didn't hurt it.

Hydrolock usually occurs on a motor that is not runnning, when fuel (or coolant, I suppose) runs into a cylinder with an open intake valve.

Which is the problem they're having (or had) with the new Ford 6.0 L diesels. They've had to throw some of those motors away.

Hope this helps.

 

Lets see,
5.4liters = 5400cc; this is only the volume of the bore and stroke. The volume of the combusion chamber at TDC needs to be found.
1 cylinder volume = 5400/8 = 675cc
compression ratio is 9:1

so (675cc+X)/X = 9
where X is the volume at TDC
solving for X = 84.375cc at TDC.
sound right?

In any case, I agree with pushrod. Your not going to harm your motor as long as its running and your not dumping alot of seafoam in to it all at one time.

 

Your good Rocketir! I made the silly mistake of not asking for the result in ounces (US, liquid).

Is it 84.375 or 74?

Lets see, 84.375 cubic centimeter (cc) = 2.8530582 ounce [US, liquid].

74 cubic centimeter (cc) = 2.5022377 ounce [US, liquid]

2.85 ounces... or less... Ouch... I will definitely make sure the engine is warmed up!

Thanks!
