In 2003 Ford launched the 6. Powerstroke to the environment. This is the identical engine that Worldwide calls the VT365. This engine has obtained a genuinely undesirable reputation in the diesel environment due to reliability troubles. We will tackle a single of the dilemma areas here these days, the EGR method. Prior to I go any farther, please fully grasp that the EGR method is an emissions machine. It is against Federal legislation to tamper, take away, or render an emissions method inoperable. Please comprehend that all the information in this post was collected from off-street only trucks and I do not endorse the removing or tampering with of any emissions system of a motor vehicle that is utilised on manifeste roads. All the info acquired for this post is from testing autos on our Superflow chassis dyno in the shop. It is up to you and your mechanic to decide what actions you want to take in modifying your truck. Use this information at your own danger.) 1. What is the EGR method and why do I require it? 1 of the most frequently asked concerns we receive is what is the EGR technique and why do I need to have it? We will not have to go into lengthy technical descriptions here. EGR stands for Exhaust Fuel Recirculation. To meet specific emissions expectations, it is required to reintroduce exhaust gases into the intake air in buy to provide particular components in the exhaust in amounts set for that 12 months of truck. Of training course you wouldn't want to dump scorching exhaust gas immediately into the intake manifold, so that is why there is an EGR cooler. The cooler has motor coolant working by way of it and appears very much like a typical radiator or heater core. The exhaust gas passes by means of this modest radiator and lowers the exhaust gasoline to a temperature that it is capable to be introduced into the consumption system at. On the six. Powerstroke motor, it is an incredibly basic program consisting only of a cooler and a valve. When the engine's personal computer decides the EGR valve should open under selected situations, the exhaust gasoline is permit out of the cooler and into the intake manifold. And right here we have the 1st hint of a difficulty the exhaust gasoline is constantly in the EGR cooler. 2. What goes improper with the EGR system and how can it hurt my engine? The big problem here is warmth. It is possible for a totally stock motor to create exhaust gasoline temperatures nicely in excessive of 1000 degrees. So envision taking 1000-1500 diploma air and constantly running it by means of your heater core day soon after day. How long do you believe it would very last? Next, set that heater core in an enclosed box that has to endure not only the large temperatures, but also 10-50 psi of exhaust backpressure that is constructed prior to the turbo it and the exhaust manifold. Even though the cooler is made out of components that are meant for greater temperatures, it is not a issue of if, but when your cooler will fall short. Greatest circumstance scenario is that the cooler just leaks a minor coolant into the exhaust program and it passes out the exhaust and you just discover some coolant loss. Worst situation situation, exhaust strain is ready to enter a break in the cooler and enter the coolant program which only runs at twelve or so psi max. The substantial strain will wreck head gaskets and oil coolers. They simply weren't created to withstand that considerably strain in the coolant program. Also, the coolant method are not able to maintain the truck calme with that much strain in the technique. This is why you will listen to about or may possibly have seasoned coolant puking out of the filler cap on the degas bottle following pulling a load up a extended hill. The cap is built to bleed off strain over 12-14 psi. The elevated coolant temp and added stress becoming pushed in from the exhaust will push coolant correct out the cap.We have a truck in the shop proper now with a blown EGR cooler and head gasket. The strain in the coolant program had gotten so higher that it blew 1 of the hoses proper off the coolant bottle. This truck was a bone stock operate truck. This blown cooler problem only gets worse when you set a programmer on the truck that raises exhaust fuel temperatures a number of hundred degrees. If you place your programmer on the greatest setting, hook to a large trailer, and then go tugging up a long quality, I advise you put your mechanic on speed dial. You will need his providers shortly. The other problem with the technique is that the EGR valve consistently gets coked up with exhaust soot. The dirty exhaust gas passing by it deposits soot on the valve surfaces. Quicker or later the valve will get adequate soot on it that it cannot near and work usually. Exhaust gasoline is continually pouring into the intake manifold now. This problem causes extreme drivability problems, inadequate fueleconomy, and low energy. If you have owned a six. Powerstroke for extremely prolonged, you have no doubt changed, cleaned, or had your EGR valve checked because of this dilemma. 3. What can we do to fix this dilemma? There are a few of fixes to this problem. The initial and most evident is to basically eliminate the cooler. Unfortunately, that would be in opposition to the law. We do market an EGR delete kit to do just that if you are likely to use your truck for off street only. This kit completely removes the cooler from the truck. There is a line that bypasses the coolant from wherever it will come out of the oil cooler right to exactly where it when came out of the EGR cooler into the intake manifold. There is also a pipe that replaces the factory up-pipe in between the exhaust manifold and the turbocompresseur. Some many years have a scoop in the factory pipe to help immediate exhaust fuel into the cooler. Because the cooler isn't really going to be there any longer, we need to have to substitute that pipe with 1 that won't have the flange for the cooler nor the scoop. There is some discussion on how significantly variation in functionality replacing the up-pipe in fact tends to make, but I personally would just like the stupid scoop out of there if it was my truck. Also, we are taking away 1 more area to have an exhaust leak by not leaving the factory cooler flange with some type of block off in it. The other repair is to exchange the cooler with a "overall performance" one that is not suppose to rupture. I have in no way personally set up a single of these myself. I truly will not believe in them. Even if the cooler will never ever pop with a far better unit in there, you would still be finding exhaust gas into the intake technique. If you have at any time torn down a 6. Powerstroke, you would be astonished at the volume of soot that collects on the consumption passages and intake valves. Letting dirty exhaust gas into theintake manifold is just a undesirable concept the total way around. If you are on a restricted finances, even now underneath warranty, or anxious about not having the cooler in there for emissions, you could just block the stock cooler off. The quickest and ideal lower finances repair is to put a freeze plug in possibly stop of the cooler and weld it sound. This way no exhaust gasoline can enter the cooler nor can any coolant exit if the cooler ever ruptured. You even now have the dilemma of the scoop in the exhaust pipe, but this lower buck repair will perform ok if you can not afford the delete kit to do it right. With this becoming mentioned, I would still set up the bypass kit on my own personal truck just to be rid of the entire mess for good. four. Will deleting the cooler have an effect on the way my truck runs? Will I get a check out motor mild? The answer to the 1st query is yes. You should see an increase in fuel mileage, a minor quicker spool upof the turbo, and normally a small decrease EGT's. There are no adverse overall performance results from getting rid of the cooler no issue what your pleasant Ford technician tells you. It looks like a misuse of your money to install a high movement air filter or cold air consumption technique if you have sizzling, dirty exhaust gas pouring into the program just previous it. As for the check engine mild, you should not get 1 at all as prolonged as you leave the EGR valve in the manifold and plugged in. There is absolutely no explanation to get rid of it from the method the moment you have eliminated the cooler. The laptop or computer can open up and shut it as numerous times as it wishes. There is no feedback loop that lets the pc know no matter whether or not the exhaust gasoline built it into the intake manifold when the valve is open. The laptop or computer will remain pleased just opening and closing the valve at will and no check motor mild will be lit. There are some delete kitsout there that have a block off plate for the port where the EGR valve goes. I never recommend setting up them. For starters, there is no purpose to block it off if you have the cooler deleted given that no exhaust can get by means of the valve. 2nd, you will have to leave the valve plugged in and laying on the motor to stave off check motor lights which is kind of amateurish at very best. 5. Is there anything I can do to extend my EGR cooler lifestyle if I want to depart it in? If you do not want to eliminate your cooler for fear of black helicopters and jail time for tampering with Federal emissions products, there are a couple of items you can do. 1st off, the decrease you can keep your exhaust gasoline temperatures the far better. Installing a high flow exhaust will help reduced your EGTS substantially. A larger a lot more successful intercooler like the Banking institutions Technicooler or the Spearco upgrade will also assist. Putting in a turbocompresseur that moves a lot more air like the Garrett Stage 1 will also support reduce EGTS. And lastly, setting up a pyrometer to maintain on eye on exhaust fuel temps will permit you to again out of the throttle when they get as well high. Also making sure you operate oil that has the right certification for your motor will support keep soot down a minor. In summary, I firmly believe all the horror stories of multiple blown head gaskets can be blamed on two items: 1st is really higher timing in some of the first functionality programmers that were introduced. They simply did not know correct absent that the six. would puke the gaskets if more than twelve degrees of timing was used for the actually scorching plans. The seven.3's would stand up to that a lot timing and more no dilemma. Secondly, I think blown EGR coolers contributed to then and even now are triggering blown head gaskets these days. I realize the need for cleaner emissions, but at what value? Many thanks for reading, John Anderson
