has any body delt with a timing chain isue on the 04 and newer 5.4when idiling it is real noisy, i had heard they havy junk tensioners, what do you guys know about this and geting it fixed.

 

Sure it isn't cam phaser noise?

 

yea i havent heard of any timing chain problems with any of the v8's, dont think that thats your problem. just my 2 cents

 

Some times the tensioner goes bad and the chain slaps. In some cases it wears a hole in the front cover. Replacing the tensioner will involve removing the front cover. Strangely enough the VCT valve body assembly has an internal filter and a passageway that feeds oil to the tensioner. If it is clogged you may not get enough oil pressure to the tensioner. I would check that first before removing the front cover.

Actually I noticed this has become a problem on these trucks..maninly the '04's. Mine is really bad. Be sure it is the timing chain. They are usually more pronounced at slower speeds then at idle. Use the search feature and you will find some topics about this. There has been alot of threads about this problem here latley.

 

thanks, i have heard about the cam phaser as well but on start up it sound more like a slopy chain but im not a ford tech i im a motor cycle tech, ime wondering if this is sumthing i want to tear into, pay to have fixed or let it be

 

All I know is that it is a whale of a job. Took mine to 2 different dealerships both said I was lookin at way over $2000. They said it is very labor intensive.........12 to 16 hour job. Right now, I'm still trying to find a good (and cheap) independent mechanic, cas I just cant afford 2 grand. What I dont understand about mine is it only starts when the engine is been ran at normal temps.

 

ya mine is way more noticble after i have let the truck warm up and its at idle but the other day i started it up after it had ben siting a week and for 2 sec at start up it sounded like the chain was hiting the cover i had a few budys over and they all turned to look it was so loud, i dont realy know any thing about this 5.4 but im hoping it dont skip timing and smack the valves with the piston
