Hello everyone! I experienced a drop in oil pressure on my 1998 Expedition 4WD. I pulled the oil pan and found pieces of the timing chain guides. This engine has 195,000 miles on it. I am trying to decide if I want to tackle replacing chains, guides and tensioners. I would appreciate any suggestions from those of you who have done this before. Is there a detailed guide for people like me who don't do this work all the time?

 

There are many threads floating around here covering the repair.

Here is a 6 page one that has a lot of information throughout.

Any recommendations on where to get parts? (quality/price) I would want to spend as little as possible but not end up with junk.

 

Go here: RockAuto Parts Catalog and look in the engine section for the timing chain items.

 

I did it on my 99 expedition, it's not that difficult, just time consuming. Just be absolutely sure you lock the timing chain, if it slips you will bend a valve, don't ask me how I know...

 

That just sucks big time.

 

Two years later, I finally tackled this job! I parked this Expedition and debated whether I should try to make the repairs or just let it go. About a month ago I finally made my mind up to try do do it myself. After much internet research, I gathered the parts and tools and I'm happy to report that my efforts paid off! The engine runs smooth and quiet now. I spent the better part of three weekends but I think it was worth it.

 

Congrats, i did this about a year ago on a 2001 Navigator 5.4L DOHC. What a pain! Had to take the big ol intake off, valve covers, and most of the front of the engine to get the timing cover off. Got the parts from Amazon for about $200 and took the better part of 2 weeks to do after work. Shops wanted $700-2500 to do this.
