I have an 08 with the 3.8l. On the back of the block, passenger side there is what appears to be an EGR valve. There is a hard line coming out of the valve going up to the top of the intake. The EGR valve itself is broke and seems to be causing an annoying tick. Like an exhaust leak. I can’t seem to find any EGR delete kits for the 3.8. Does anyone have any options or have done this?

 

why not put a new valve in it?

 

I could. That wouldn’t be a problem but if there is a delete option I would rather do that than putting my exhaust back into my intake and building up more deposits than necessary.

 

EGR= Exhaust GAS Recirculation where its intent is to put gas back into the intake which didn't burn and not exhaust.

 

Not quite.
EGR isn't meant to introduce gasses that didn't burn. It's meant to introduce gases from the exhaust that won't burn. Net result is lowered peak cylinder temperature, which reduces production of nitrogen oxides.

I agree with the OP in that it's not a clean system. However, if the valve is working properly, it's not dirty enough to cause a problem.
I think the pcv system puts more crap into the intake than the the egr system.

 

You are probably right about the PCV. I just know when I took the upper intake off and looked inside there was a lot of build up. If I can eliminate some of that by a delete I wanted to. This if my first Jeep and I couldn’t find a whole lot on if the EGR delete helps with fuel economy or anything like it does on diesels and some other gas engines. Thanks for the input though. Would like to know if anyone has done a delete and it actually help or if I’m better off just replacing the valve.

 

In addition to lowering Nox emmisions, EGR also increases MPG by reducing pumping losses in the engine -- Essentially raising the manifold pressure with a little inert exhaust gas. If the pressure is higher in the intake manifold, it takes less energy from the crank during the intake stroke.

For a street-able JK, deleting kills ~1mpg in hwy cruising. When the EGR is opened, the spark is also advanced further to compensate for the slower burn rate. Proper deletion is done in software. Just blocking the damn thing off will rattle the engine to an early death with over-advanced timing. Any rumors of better MPG from deletion is absolute bull$hit (on a gasoline engine like the 3.8L).

Also note that EGR is only used at mid-power. It would rob power at the high end, and any EGR at idle makes it run rough. Bottom line, fix it.

 

Already fixed. I bought a new EGR valve for $85 and replaced it in about 30 minutes. 👍

 

30 minutes? You're one of the lucky ones then.

 

It was surprisingly simple. I used a ratcheting wrench and just pried the trans dipstick tube back a little and the bolts came right out and went right back with no issues. That’s definitely not the case normally though.
