Linky won't stick.

That's it! The links I had were evidently secure one's. Or my phone is about full of data.
The clear path of motor oil to the cam phasers is critical to good driveability. So, using cheap or unknown quality of oils or change intervals go beyond what they should be. Will be the death of the VCT system. Just one cam phaser component is several hundred dollars. Add labor and even the most expensive oil starts looking pretty cheap in comparison.

Thanks for this link. I used to own a Scion xA with their version using VVT-I - so this was informative as well as insightful into how other Makers worked their magic in their efforts to get more out of these motors.

Again thank you...

One question though - in the Scion version, they use a screen filter - a lot like that of an Transmission Oil screen pre-filter to keep the oil channels around that solenoid clean. They only used one solenoid and since this was a simpler design of advance and retard, (2004 version year) only one solenoid was used to divide the cams as advance or retard their timing - but at one time simultaneously.

I used to have to take a Torx bit #40 to remove a spring and this pre-filter about every 100,000 miles - and was done during an oil change you can see this filter kept out dirt and metal bits from entering into this system and the Service manual even alerted you to the possibly of premature failure caused by lack of maintenance of this pre-filter.

​

Does Ford also provide any pre-filter or a method to purge the system to "flush out" dirt that may have reached further up into the piping as well as the chambers? Why, it is my fear - some of this simply cannot be avoided because of coking that oil can exhibit due to the age of the motor and the conditions it will be used in that dirt or coke can flake off the channel path and flow into other areas before it falls into the Engine Oil catch drain-pan..

How is this done on a Duratech motor, is there a pre-filter or screen that can be removed and cleaned to keep the system from plugging or otherwise a premature failure caused by dirty oil? OR is there a procedure someone would like to share in which to purge and remove debris that may have collected during the service life of the motor?

Inquiring minds would like to know!

I'm unaware of any screen or pre-filter on the Fiesta engine. I would think that something like that would be as much problem as a preventative area. It's just better to use high quality oil and filters. My 2000 Ford ZX2 has an early version of VCT . Routine service has been an effective way to prevent issues.
These cars really impress me. They are mostly well engineered.(DPS6 excepted) run consistantly well for many miles with only the most simple service required

My last Ford was a 93 Tempo 2 door, the car was reliable except for the fact that I couldn't keep count of how many inner and outer tie rod ends I went through in 4 years. It handled like crap until I put a rear sway bar from a V6 on it. Still, it doesn't even compare one bit to a Fiesta.

Yup. I had a 85 Tempo diesel. The Tempo went through tie rods because the steering rack was originally designed for the 81 Escort! The rear brakes on the Tempo were the same as an Escort station wagon. The engine block was a 3.3 lliter straight six from the Fairmont with two of the cylinders loped off and a more modern head design! I wrenched at a Ford dealership in that era. I'm not being critical of it. It worked and Ford sold lots of them.

Yikes. At least mine had over 100hp, I couldn't imagine how slow that diesel must have been, but at least you had a stick (I think all diesels were manual), I had the extremely lame 3 speed auto.

Maybe the combustion chamber design was more modern, but they didn't even bother to make it a crossflow head. I would still like to own another one (an 86-87 model with a 91 Taurus 2.5L and 5 speed manual though).

Here's a pic of it, in all of its converted to a Mercury glory. Got rid of the black lines on the tail light lenses too.

oh yeah. The gasoline engine Tempo was a hotrod compared to the 66 h.p. diesel version! But I liked it for what it was, an insanely fuel efficient way to get around. The Tempo has the distinction of being the only Ford passenger car to be sold in North America that was available in four cylinder or V6 gasoline models
, Diesel four cylinder and also was available with all wheel drive ( 4cyl/at only) and also was the first Ford sold in America with a driver's side airbag (1985). Several of us in the dealership openly wondered what Ford was planning to do with that humble chassis next! Ford really worked the living shit outta that car in terms of variation.
