I have a 2005 EB with 130k or so on it, the cam phaser, oil pump, or timing chains have went out on it. will any other motors/years besides the 3v 5.4l motor bolt in this with out a ton of fabrication or retro fitting? I may just replace it but don't want to put the same ol junk in it.
If you're handy with a wrench go for the timing job. I did it myself over a weekend and it was a gratifying job. I had just under 100K on my 05 and it was starting to sound like a diesel. I never had the stumble, misses, or CEL. I did it as a preventative correction. If you do it, make sure that you replace the timing chain tensioners... The seals on the back of the tensioners are really the smoking gun for these issues. The o-ring seals from the factory fail and lead to oil pressure bleed-off. The pressure doesn't make it up to the phasers, and all hell starts to break lose.
From the top of my head the parts changed were as follows:
Phasers, chains, guides, tensioners, (I changed the solenoids too, but it wasn't mandatory). I also changed the oil pump as there has been significant research that proved the flexing of the back plate of the pump above 3,000 RPM. This lead to some bleed-off as well, similar to the tensionser issue. I used a Mellings high volume pump with a billet back plate. The pump is on the crank snout and you do not need to drop the pan in order to change.
While I had it apart, I did a power steering pump ,a water pump, and the serpentine belt as they were easily accessible.
Big job, but when you hit the key and hear nothing but injectors and exhaust, it restores a lot of confidence in your ride.
