Welcome to the forum,
Take some time out to research the forum rules and follow them by introducing yourself in the "newbie section"
I notice if you filled the vehicle description out correctly on your profile correctly; you drive an ST understandably its not a modern diesel engine so your personal concern over egr blanking of your own vehicle is non existent.
Moving on from this mate; ford didn't design the modern diesel engines which they have fittted to there cars which half of your life did you spend being the mechanic ?
My guess is; youve spent the first half
And now spending the second half being an arrogant !Removed! hole
The diesel engines ford now use with the exemption of the 1.8tdci are. Citroen Peugeot engines,
Ford head puffin a cigar got on the phone too gas monkey "gimmie cheap diesel engine that's economical, we'll sort the body just gimme something cheap with high mpg" they don't care about long term reliability that doesn't make money as I'm sure you as a mechanic yourself are well aware; fix it right the first time they won't be back motto.
Take a seat for this one; your ST engine.. its a Volvo mate, not a ford designs engine neither, has the inlet penillum split on you yet? Due at around 25,000 research that as it applies to your motor directly.
Aswell as the headlight washer jet covers known to depart from the body at 5,000 upwards,
Now on diesel engines the egr valve recirculates waste gasses in to the induction system instead of 100% clean air, this is in a bid to create an engine that wins stars on the European sales market for fuel efficiency and lowest in class emissions,
They want to sell, sell, sell, they no longer care about reliability.
The recirculation of waste gases is proven to contaminate the oil with excessive levels of carbon thus blocking oil feed pipes to the turbo causing turbo failure and excessive engine wear,
If I was a car manufacturer or a mechanic Id be all in favour of the egr and agents blanking it,
Because as a car manufacturer or a mechanic Id be making more money replacing blown turbos, blocked oil feed pipes, contaminated induction systems and carbon caked oil sumps.
But since I'm not either, as an independent road user and daily driver of an egr equipped vehicle I have done my research and decided the best option for me with my car is to blank the egr valve and prolong the life of my 32,000euro four wheeled investment.
I'm speaking from experience with diesel engine and from my experience buddy when it comes to egr blanking and understanding its functionality your speaking from your anal passage.
Typical mechanic too,
Opting to change the glow plugs when in discussion about working on a completely different part of the car
Any chance your a ford mechanic?
They changed my whole pollen filter housing when changing the pollen filter,
I'm not here to convince anyone to do anything,
I'm talking from personal experience and sharing that with others.
The ford mechanics don't design the cars, the he ford mechanic agreed with me on banking the egr,
He doesn't drive a ford body or Peugeot engine, he drove a Daewoo,
Again his personal experience added to my own personal experience and research after all he's servicing the things every day, he doesn't design them but he sees the wear and tare and with that knowledge he agreed yes blanking egr is most certainly the thing to do for lower carbon contamination.
