2nd EGR repair...

[haymaker]

Just blew my second EGR yesterday on my '04 6.0, the first went about 20k miles ago, of course now I'm over 100k miles and out of warranty.
Dealership is telling me that ford recommends on the 2nd repair of the EGR to also replace the oil cooler, an extra $900
Is the replacement of the oil cooler necessary? or can I get by by just replacing the EGR again, please advise...

Did you meen egr cooler? Yes we replace the egr cooler and the oil cooler at the same time. 9 times out of 10 the oil cooler is what makes the egr cooler go out.

How are the two coolers related by failure?

I posted this in another thread, but the coolant feeds both the oil cooler and EGR cooler. While I'm not convinced that the oil cooler causes 90% of EGR cooler failures, Jon's a PSD tech and has seen a BUNCH of these things.

Could you just do the EGR delete and never have to worry about it again? Just an idea.

Ive heard it both ways and cant get a straight answer. I have heard the oil cooler gets a restriction and cuts water to the egr cooler and that melts the egr cooler which makes sense to me and i've heard that the egr cooler gets hot and takes the oil cooler out, either way its a problem. I lean to the egr cooler taking the oil cooler out.

what exactly is the EGR delete? is that the mod that I read on another thread here? I wouldn't know where to start. This all happened when I was pulling about 12k of trailer and tow mode downshift kicked in, boom! white smoke everywhere, second time in 20k miles the first time they didn't replace the oil cooler.

My 04 is going in on Tue. for the egr cooler replacement. Its been leaking for a few weeks now, but the dealership never said anything about the oil cooler. Should I ask them to check the oil cooler too while they have everything apart?

EGR delete is where you unplug your EGR valve or have it added to your SCT custom tunes. It will keep your EGR valve closed and prevent common problems associated with the EGR, but won't prevent the EGR cooler problems, like coolant puking and worse - hydro-locking your engine.

Absolutely!!! It's more difficult to determine if the oil cooler is bad, unless you have oil in your coolant or coolant in your oil, but Jon (or one of the other techs) might be able to give some pointers.

If the oil cooler is bad you'll have high engine oil temps. The engine oil temp shouldn't be more than 20* over the engine coolant temp. The truck can be hooked up to IDS which can read both temps and make a determination. Also, the oil cooler gets stopped up with casting sand from the inside of the engine block. Adding a coolant filter can help this immensly. You'd be amazed at what comes out of the coolant filter after about 500 or 1000 miles, even on older trucks that have already had the coolant changed.
