Is there any way to clean oil and gunk out of the intercooler?

[h1gg1n5]

So I have done my CCV mod, EGR is removed and deleted the DPF as well. When all this was being done I noticed the huge amount of sludge and oil in the intercooler lines and intake etc. Is there any way to get all this out? It seems to me that it would function better if i took the time to clean it out but I have not seen any threads at all of people cleaning it out.

I'm thinking remove the intercooler, plug the ends and dump brake kleen in there and shake it around for awhile then empty it out and let it dry. I would also like to clean the pipes and everything else as well.

Or is it fine the way it is? Now that all my deleting is done I want it to run as best as it can and for as long as it can.

Here's a few goggle searches I came across:

I was just about to ask the same question!

Since you have the CCV mod done, just drive, get on it some and eventually all the oil will just blow thru.

I will let it sit for a bit and run it and see if it cleans it out and open it back up in a few months. I almost want to dismantle all the parts and clean them all out it's so gross in there. That can't be too good for the cooling properties and long life of the parts.

Is it really that bad. I took my Intercooler hoses off and found some oil residue but very little soot and that was before the EGR delete. Do you idle the truck often and for long periods of time????

My intercooler pipers and intake elbow are coated very thick in soot and a coating of oil on top. I bought the truck with 142k and it was bone stock.. I'm pulling everything and soaking in a mild solvent tank I use for gun parts.

Wow, yea I would definitely clean what you can. The only concerns I ever had with cleaning intakes and other air exchange systems was to be sure that what ever I use to clean doesn't leave a residue and any loose debris should be removed. I've used carb and choke cleaner and my fancy air operated vacuum from snap on to clean up debris. My intake had some soot and oil in it before the EGR swap at 83,000. But the truck is at the shop getting a new trans so I cant tell you if there are any changes with the EGR delete

Soot can be good and bad. They probably didn't beat the piss out of the truck "the truck ran cool" but all of that incomplete combustion has left a mark on some parts.

There shouldn't be soot in the intercooler. The EGR cycles from the exhaust straight into the intake manifold. Shouldn't go thru anything else...

Brake clean cost to much... Mineral spirits is cheaper I'd just use that. Or acetone, that won't leave any kind if residue! I don't have the ccv mod done, thought about talking my intercooler off and tilting it over to see how much oil is in there. Dark horse diesel in Alabama makes a great ccv kit that can be either Closed, or routed to vent through the exhaust.
