How did this end? Looks and sounds identical to my hole in valve cover issue

[IMG][/IMG]

I am dealing with what appears to be this same weird issue also.

2006 f150 150K 5.4 blew a hole out of the RF valve cover.

I could see where timing chain had etched marks on the piece it blew the hole out but engine still runs ok. Obviously I'm not driving it and caught it early.

Anyone know of this issue or how this one was resolved?



Here is a closer look at this mystery part found in the motor around my timing chain. Can anyone identify this thing?


so this appears to be part of the timing chain guide, as my buddies tried to tell me. i feel better about ordering, and this is a question for the forum gods, but i was thinking i need this kit. Any advice?

The other thing is, since this is going to all be torn apart, any performance upgrades or more importantly maintenance things like belts, hoses, stuff that's going to be torn apart anyway.

Swapped the motor

Swapping out the timing chain assembly was the plan going into the shop. Once he got in there though, turns out the motor was in pretty bad shape anyways (not by any fault of mine). So in my case, I swapped the motor out. $3333.33 was the price of my bill.

Might have same issue

Hey guys. Might have a familiar issue I have an 06 f150 5.4 triton. It's been having fuel and misfire issues and the other day I got under it and seen the timing chain cover had about a 2 1/2 inch hole in it right under the tensenior pulley(same shape). Any ideas? And what kind of problems would a hole in that area cause?? Thanks in advance...

So I have an 04 F150 and started it in my driveway today and heard a clunk so looked under hood and similar that it has hole in valve cover right at chain. Itís has had a tick that I put off clearly to long. It just sits in my drive way lately since I take a work vehicle home daily and use wifes suv for everything... to many kids to fit in truck. Wondering if I should attempt repair, never took anything apart engine wise, just plugs and simpler maintance. I repair appliances for a living so fairly handing. Itís starts right up just leaks oil all over. Iíll try to add pics, just joined forum.

You probably need a complete timing set. Chains, tensioners, guides, phasers, VCT solenoids, and a high volume oil pump.

Was that a used or rebuilt motor? $3333 sounds like you got a good deal for a motor and the labor.

What other kinds of problems did you find in the original motor?

Well obviously your timing chain isn't broken. But it probably either stretched or jumped one tooth and your valve timing is now incorrect and that's why the engine is running rough. Assuming that their aren't other problems, replacing the timing chain and the tensioners should fix that. But if you keep driving it the problem WILL get worse and will very likely damage the engine.
