EGR Delete in progress
For the past few days I've been working on this after dumping a great deal of oil and coolant on my driveway. Instead of making a hanfull of threads with questions in each, I've decided to consolidate into a single thread.
So far, I've got the the turbo off, intake off, turbo to cat unbolted but still in place. Tonight I'll be working on the up-pipe from exhaust manifolds to the turbo. I forget which kit I bought, it was a few years ago and I'm just getting around to it now. Any future issues I run into I'll drop into this thread.
To date the only thing that really gave me an issue was the drivers side turbo mounting bolt, but when I bought the proper pieces to remove it, it came out fairly easily.
Can't wait to have my truck back, driving my shop car everywhere is getting old, it feels like I'm no longer king of the road in a 91 volvo wagon...

The up-pipes to the Y pipe were really annoying. The bolts were near impossible to get to. The top rear bolt to the passenger side up-pipe to Y pipe I ended up getting from the bottom with a 2ft extension, while wedging a 10mm wrench on the top to keep the bolt from turning. I tried from 15 different angles to get that sob off up top but it just wasn't happening. But, it's off.
Only the exhaust from the passenger side goes to the egr and not the drivers side? That seems bizaar, like they completely half-assed their egr install just to meet some government compliance.
I got the passenger intake manifold bolts loosened, I got a bit lazy over the 4th of july 4 day weekend, so it's taking a bit longer than expected. I am looking for a diagram on the bolts for the intake manifold and egr so I don't fight myself to death because i missed one. The metal gasket from the up-pipe to the Y pipe fell down the back and landed somewhere on top of hte transmission bell housing, where it's now sitting along with 3-4 sockets and a wrench, so I'll have to go down and grab all that stuff before I'm done.

I pulled the turbo already, leaving hte drivers side up-pipe in place so I don't have to deal with putting that together again. I'm finally seeing hte light at hte end of hte tunnel. About to pull the egr cooler off.
Question is, do I need to replace the oil cooler? How can I check?

Did you have temp spread issues before?
Do you have a filter? Have you flushed it out well?
Common sense says since you are that far in, do it. But there are other factors too.

I haven't flushed anything yet. The temp has always been consistant and with-in normal range. The other concern is time, and how much is it. Truck has to be ready to go by sunday afternoon. Is it difficult to replace? I thought it was up by the radiator.

The oil cooler is under the oil filter. I wouldn't try it if you have to have your truck on Sunday as slow as you're going. I think it's about 3-4 more hours and $300.

I'll tear it apart again later hwen I have more time. I'll have 2-3 hours a night through friday, and all day saturday and sunday.
Would the coolant have gotten into my oil, or just oil into the coolant? I just changed hte oil a couple months ago and it's still registering on the dipstick as being only down a small amount.
I had to take a hiatus from the work as I got married on the 30th, if i spent hte honeymoon under hte truck it'd be the worlds shortest marriage.

Usually EGR Cooler failures are caused by a failed oil cooler. The oil cooler is another hour job with the intake off. Just remove the cover on top of the motor at the front. It's pretty easy...
If you have oil in your coolant, that is not a EGR cooler failure.
