Replace Donut
Well it's getting cold again and my coolant leak came back, I was hoping it would somehow fix itself over the summer.
Last winter I had it narrowed down to the donut, I actually bought one and a couple other orings for upfront. I really don't feel like fixing it but I'm tired of loosening the cap and releasing the pressure. It only leaks after it cools down and gets cold.
Anyone ever just replaced the donut? I've read it may be possible to just loosen the intake and lift it up enough to replace it. If I can just loosen it up any idea what else has to be removed? Turbo? It's been 15 years since I pulled the intake, I just can't remember, maybe someone has done it recently can give me heads up.
I need to buy me an odawg so at least I can get some satisfaction out of the job.

You don't need odawg.
I'm not a friend of the "quick solution" only loosen bolts and put new donut in. Clean everything on top of engine, remove manifold and clean it inside, and re-install everything with new gaskets.
Install EGR delete if you still have EGR cooler running.

If you're thinking delete or not to delete:
2006, 62k (original) mls., babied and super clean:
Now she needs complete rebuild, here in Germany: 25000$ includes injectors, Turbo, and all the upgrades.

As far as the delete,, I did all that over 15 years ago, man, I couldn't believe how bad the intake was. I tell people that fight the idea to wait till they see the inside of the intake, that might change your mind.
You posting that video are you saying there could be a chance of the donut leaking into the intake, or you think it will always just leak to the atmosphere.
Thinking about it now,, I got to go let the pressure off,, I'm wearing out my hood shocks.

I just wanted to show with the video what damage an EGR cooler can cause. Important in my eyes is also that the engine does not suck exhaust gases and gets only clean air. A CCV reroute serves only to ensure that the intake system is not oily. The oil "mist" has in principle no negative influence in the engine.

I certainly don't want to say the "quick fix" doesn't work, but in my eyes it's not a good fix. Dirt also gets collected at this point and should be removed. No matter what you do to these engines: if you do it right, there are no problems with it and the engines run inconspicuously.

I replace the donut on my first truck when I had to
take the intake off due to a broken bolt in the oil cooler
assembly. While I was there I install the Bullet Proof
Diesel EGR cooler and clean the intake.what a nasty
mess the water was that I used to clean it. The chemical
I use was precision clean simple green. It is
not harmful to aluminum like regular simple
green is.

Man your pictures, you should collect them all up and publish them (maybe get Jack to help), they are so helpful, it really puts it in perspective regarding the "quick fix". I will definitely pull the intake now. Thanks

I will be removing and disassembling an engine next month with severe damage from a 500mls ride with a leaking EGR- cooler. A lot of water got into the whole engine. I will post the results:

They are stainless, softer, so highly pitted. I need to change the exhaust valves and ended up replacing them all.
