i notice in one of the previous threads that there are recalls about the ebt sensor for 6.0 engines up to 05. my vehicle has one of the symptoms that one of the other posts had mentioned. my vehicle has developed a romp romp sound,
a noticable difference in sound, at idle and even when driving. could this also be the ebt sensor even though it's an 06. I have had the compression checked and it's perfect and there are no misses at all. please advise

 

Check this list and pick another acronym .

EBP. Not FBI... Sounds to me like turbo chatter. Or prob with the turbo

 

I have been told by two different mechanics that my issue is valve related but there is no evidence. had more tests done today by ford and they found nothing. the sound is on the drivers side and sound like its coming from the breather compartment. there is definately exhaust or what appears to be exhaust doming back through the intake.

 

check the CAC tube connection make sure there not cracked tighten the clamps up It may be hard to see but the up pipe towards the back fire wall look for soot on fire wall

 

That is turbo chatter....turbo fart. IT IS AN ISSUE WITH YOUR TURBO SON... Take it to 1 of them mechanics u mentioned,tell them to run a turbo test...if they are good techs they will have a scanner that will test the vgt. Now if they dont,....??? RUN!

Trust me,i deal with all sorts of turbos.....all day....even turbos for sea doos! So trust me/us/FTE....test the turbo!

 

I hope your romp romp is not like my thump thump...

I'm $2,300.00 into making the thump thump go away.

 

i checked your link you had posted and your truck is doing exactly what mine is doing. Have you not found your problem yet . and what have you been told

 

Did you read my thread that I started?

There's 12 pages of what I found and what I had to do to locate the problem.

Read through it. I found a bad lifter on the #6 cyl. exhaust side.

My truck stopped running all together prompting me to dig in.

The lifter fell apart spilling the needle bearings everywhere including in the lpop. Took the pump out causing the engine to quit.

Pull the drivers side valve cover off. Turn the crank over by hand and observe the rocker arms. My rocker for the #6 exh. valve was real loose almost like ready to fall off.

There should be pressure on the pushrods in the combustion stroke to hold the pushrod securly against the rocker arm. My rod was loose to the point where I could grab it and move it in and out about 1/4".

The rocker should be fairly secured on their pivots. Mine was real wobbly when in the combustion stroke when there was nominal lobe pressure on the lifter/pushrod linkage.

The bad lifter was not opening the valves enough during the exhaust stroke leaving some of the combustion to be expelled during the intake stroke hence the thump, thump noise I had.

I also noticed that the rocker was missing the pad that rides on the bridge for the two exhaust valves.

If I were you I would not run the engine until the valve cover is removed and an inspection done as mentioned. If you continue to run it this way you could risk a damaged lpop, front cover and seal, plus oil cooler, and cam damage. Once the cam is damaged then the whole engine will need to be pulled and disassembled.

It may need to be removed even still if one of the lifters in the last four rearward locations is damaged as you can't get to those lifters with out pulling the engine.

Look at my thread completely. You'll see pictures of what I found.

I'm just now starting to put together my engine after the cam was repaired, and new parts replacing damaged ones..

With yours still running you may still have a chance to save the engine from getting damaged further. So you may at this point be ahead of the game.

Let us know what you find..

Also a compression test will show good. No problem with the valves sealing.

 

that is really good input for not running or trying to statrt,this problem could be catistrofic, spelling notited

 

I"M OUT good nite .

 

king air.. I went to the link you had with your post and it basically just described your problem but didn't go into the fix. could you send me a link to the 12 page conversation, it would be very helpful.. thanks for all your input.

 

Tinky, that is the link to my 12 page thread. In there you'll see what I found with pictures I took and where I'm at with the rebuild. I update it as I go also.

 

thanks for the link.. i'll keep everyone posted
