I'm not sure about the D16. Never actually seen one. I assume if you have the same egr/egr cooler to intake set up, you probably can. I have heard of others doing it, but have not seen there system.

if you are still curious about blocking the egr's the solution is fairly easy to try and if it doesn't work it takes about 5 minutes to undo.
if you have a siliconized hose running between the egr cooler and the intake(located at the front of the engine..maybe green or maybe blue if the paint has flaked off) then you can probably block the egr system.
take the hose off and get a 1 1/4 inch galvanized steel pipe plug and a hose clamp two inch will work. stuff the plug into the hose(from the intake side of the hose as it is a tapered hose) as far as you can get it in there(as close to the egr cooler as you can) and apply the clamp to the plug. replace hose in proper position and resecure.
cost about 6$ at lowes for all the parts.
have been running my d12d for 45,000 miles and .7mpg better and pulls like you wouldn't believe.
good luckxiipercent Thanks this.

if you get through yakima, wa check into mobile fleet service. this is one of the only shops that touches my truck. great guys, that do good work. i have never once had an issue with their service, and they have always got me in the shop same day and don't usually have to order parts.
Let me throw my two cents worth in this as it relates to diesel and gasoline engines in general.
I use fuel additives in my vehicles on a regular basis.
The gasoline and diesel fuel coming thru the pumps today is not the quality it should be considering how much we pay for the #### stuff. A lot of it is crap and it has a lot of crap in it.
If your experiencing engine running problems, before you start emptying your wallet on parts and mechanics services, start running some good fuel conditioner/additive in your tanks every time you fill up.
Don't be chintzy with it either. Dump some good amounts of the stuff in the tanks.
You just might be amazed at the results. If it does not fix the problem, you haven't wasted much money to fine out.
I've had some amazing results from doing this myself. Solved some running problems and saved me a lot of loot and down time.
Would love to hear some of your guys feedback after you have done this. It would be helpful to others as well.
Often times, what normally might be considered the most obvious is not always the best place to start.
all other internal parts of injector unit are covered with W2C (HRC over 90), and Volvo injector units fail with bad dozing valve! it is destroyed with nocking, not with friction, so you cant save it with additives
Another often overlooked item is the "AIR CLEANER". Once of out-of-sight out-of-mind things.
The internal combustion engine is nothing but a great big air pump. It has to have air to function. Lots of air. It breaths air. It sucks air.
Anything that impedes that flow of air into the engine will create engine problems. The air filter starts getting dirty almost immediately. Drive thru some heavy rain and the moisture degrades the paper element of the filter. Combined with the dirt and dust, the filter begins to restrict the air flow.
Restricted air flow means loss of power, higher fuel consumption, the engine is being worked harder. This can lead to other problems.
OTR trucks should have their air filters changed at least once every 90 days especially if you running in dry dusty areas, thru rain and putting on a lot of miles weekly.
It can add an additional 1 to 3 mpg to your fuel economy.
Like I said in my other post......try the simple inexpensive things first. A smooth clean running engine will always have fewer problems.
unfortunately i have heard a lot of problems with the volvo second generation trucks 670's and 780's and i am suprised that no one has confronted volvo inc with these problems . it seams to me that the design of this perticular group of trucks had some bad design flaws that volvo is very aware of and is being very quiet about hoping it will go away because the fleet operators such as us express are simply selling off their problem children and going to a different truck manufacturing company such as peterbuilt and freightliner and cutting their losses leaving us as owner operators to take up the expense of trying to fix what we were duped into buying.I for one bought my 780 to cut my maintance expenses form the 95 volvo use to own only to wind up spending as much if not more on repairs.just the egr system is so expensive that to replace it would cost more that an engine inframe on my old truck,this is insane and unacptible but owners are doing it all the time and it is killing us slowly.when does this stop.when does the volvo manufacturing corp take responsibility for their screw up and do something about this.everyone i talk to that has a second generation volvo says they will never buy volvo agian.thats alot of owner operators volvo maybe you should listen up and do something about it before you put yourselves out of business here in the good old usa after all ther are alot of other truck makers that would love to have us as their customer.any one have anything else to add,speak up its your money!
