Cam Phasers on a 2005 4.6 3V
So this is just a very brief overview of what was either a bad cam phaser or timing chain guide tensioner. A few things I learned via trial and error and to say overall, it wasn't as bad as I thought it would be. In total, I think I had 20 hours in.
It all started with this faint nose I heard on the drivers side.
The car has 72k (KMs, not miles) and I since I didn't actually know what was the cause of the noise, I decided to do a full timing kit. I replaced the timing chains, guides, tensioners, cam phasers, VCT solenoids and front seal. Decided not to bother with an oil pump as I get 75lbs at cold start and around 35 at hot idle. Water pump wasn’t making noise and is easy to get to down the road
Tip 1 = Use a Chrysler harmonic balancer puller to get the crank off. A regular gear puller just couldn’t grab on.
When my car was new and under warranty, it had a cylinder head replaced when it was less than a year old and I don’t know if the timing cover was always missing a chunk or if it was damaged by the tech. There was also debris in the front seal.
Troubling but not fatal.
I rotated the engine a gazillion times trying to get the timing marks to line up, the links were very faint but eventually I got them to line up but the right bank was off by 1 tooth.
Car ran fine with no codes up until this point, it could have jumped a tooth when I was rotating the engine and there was no oil in the tensioners? Or maybe it was always off 1 tooth?
New parts all from the dealership, there was zero chain stretch between old and new. Timing chain guides looked good with minimal wear.
Got the new chain installed and marks all lined up.
Disaster struck when I was installing everything. Using my inch pound torque wrench to snug everything up and I guess the timing chain guide bolt was stretched, I kept tightening and tightening and then it snapped.
I was able to extract it, it is one expensive bolt! $13 plus $15 for shipping as they didn’t stock it locally.
After installing the timing cover, I forgot to reinstall a sensor that goes by the crank pulley so I had to drop the AC compressor a few inches to sneak it in. That was a PITA.
My valve covers looked terrible, so I sanded it and painted it Duplicolour Ford Blue
Was nervous as hell starting it up but it runs great now!
It isn't a terribly difficult job, just takes a bit of time!
