2.3L ('83-'97) EGR bypass? More power good idea? 96 HO 2.3L 4 CYLINDER XLT 5 SPEED MANUAL REAR WHEEL DRIVE

[Rooster Red Fixall]

I got a 1996 model XLT single cab HO 2.3 l 4 cylinder 5 speed manual transmission rear wheel drive last time I got it stuck in the mud the engine torqued hard enough to slam the EGR valve into the firewall crushing it so I'm thinking of deleting it and I've also heard that I can gain a little more horsepower which would be a major plus considering it doesn't have a lot of horsepower any ideas opinions possibly someone who has done this mod what the outcome was any benefits pros and cons any help is appreciated please and thank you have a wonderful day and God bless

I don't have any answers for you... but i moved this to the appropriate engine forum. You will likely get better looks here.

Feel free to post another introduction and show us some pictures of your truck.

Sounds like you should inspect your motor and/or trans mounts before you do anything else..

Welcome.

I don't see how deleting EGR will give you added horsepower. It's a myth regurgitated from people who don't understand what it does. Deleting EGR is actually not great on your engine. EGR only comes into play when you're cruising down the highway. The second you put the engine under load, it gets cut out by the vacuum actuated valve. EGR puts exhaust gases into your combustion chamber when the engine isn't under load. This serves two purposes. First is it burns the remaining fuel in the exhaust for a cleaner burn. Second, and this is the important one, it cools the combustion temperatures by displacing some of the oxygen, extending the life of your engine. So unless your EGR isn't working properly, it won't rob a single horsepower while doing it's job. There's just a lot of "emissions bad!" sentiment among the car enthusiast world. Catalytic converters are another long held myth. Any modern high-flow catalytic converter robs little if any power from an engine. The ones introduced in the 70's didn't flow nearly as well. The benefits are immense, though.

Ultimately, you do you. But I want you to at least understand that you're not going to see a power increase.

Yeah, that... this of course assumes the EGR system was operating properly

Eh, it's not like it's hard to fix if something's wrong. It's a metal tube and a vacuum operated valve. Of all the things that can cause an engine to run poorly, it's probably one of the easiest to diagnose. Use a vacuum pump on the EGR valve to test the diaphragm holds vacuum, and check the vacuum line for cuts or cracks. Plus it's pretty obvious when it's not working. Your truck will have a really hard time idling. It doesn't rob power, it pretty much takes away the ability to idle at all.

But again, if you don't want to have to worry about it, I get it. Blocking it off won't make the engine run poorly. But it's not going to add horsepower and you're losing the cooling effect on the combustion components, so you risk increased wear.

It is a great mod if your engine does not ping enough.

This guy is a diesel nut, so it comes from a diesel perspective, but if I remember right it is all spot on for either gas or diesel.
