ctc Posted July 15, 2009 Share Posted July 15, 2009 Hello, I'm looking to buy an Expedition from the 03-06 gen. I was wondering what the known/common issues for this truck are? Thanks in advance! Quote Link to comment Share on other sites More sharing options...

darrellblackmore Posted November 1, 2014 Share Posted November 1, 2014 My 2003 XLT 4X4 just turned 200,000 and it is running like a champ. I got 120,000 on my 2003 XLT 2X4 and running strong. I just replaced shocks al around, upper control arms and lower ball joints. Still happy with it and now riding smoother. Quote Link to comment Share on other sites More sharing options...
Mark Young Posted March 29, 2015 Share Posted March 29, 2015 Knowing what I do today I would run from this age range of expedition... About 7 months ago I bought a 2005 expy 5.4L 99K miles, I replaced the front end of the motor, cam-phasers, chains, tentioners the works now at 108K miles started with all the classic signs of cam-phaser failure (rough idle, stalling, sounds like a diesel). I attempted every fix possible to no avail, I took it to our Ford dealer and they said low oil pressure has caused cylinder wall damage= NEW ENGINE. I bought a re-manned engine from a local shop with upgraded oil pump and ratcheting tentioners to avoid chain slap and new VVT solenoids. I installed it and have the exact same problems. I get a P0012 for bank 1 over retarded. I'm sooo angry that I've spent $4500 and nothing was fixed. I think there is a PCM issue or wiring problem. However the dealership cannot diagnose it Quote Link to comment Share on other sites More sharing options...
fordtech1 Posted March 30, 2015 Share Posted March 30, 2015 (edited) Sounds like the chain is out of time. The issue with the timing chain tensioners is the gaskets would blow out and leak oil past the tensioner and give it a rattle until oil pressure over came the leak. In turn starve the head for a few seconds of oil every start. Does it still rattle? Edited March 30, 2015 by fordtech1 Quote Link to comment Share on other sites More sharing options...

The new motor has an upgraded oil pump and ratcheting tentioners instead of the hydraulic driven ones from ford. I'm trying to get rid of the diesel sound, I'm sure it cannot be good.
