No you can't clean it to cure it, any chemical that can eat sand would surely eat the aluminum quicker. Do what you have to do, do your egr cooer delte now and plan the oil cooler rebuild for a weekend or something, when they get clogged they can also rupture and dump oil into the coolant system. The hot oil is hard on injectors too so don't let it go on for too long before you rebuild it when you pull the intake to do the delete do yourself a huge favor and cut off the mounting flange that hold the cooler toward the back of intake, leave at least an 1/8th inch of meat on it outside of the normal shape of intake, you don't want to cut into the actual intake part and weaken it, that way when you go to do the oil cooler you don't have to remove the turbo to take the intake off, that little cast in mount is the only thing that prevents you from removing the inake past the turbo.

 

Wish I had a shop man. I do work on them on the side a little bit here and there, but where I'm living now I can't really do any major repairs. Oil cooler wouldn't really be a problem at all though. Looking at buying a house soon so I can hopefully do some more work on the side. I wouldn't mind doing some things though. Just shoot me a PM we can talk.

Where are you at?

Unfortunately there is no real good way that I've seen to clean the oil cooler. It seems even if they are flushed in both directions they still clog really quickly again. A coolant filter, a coolant flush, then a fresh oil cooler rebuild really seem to be the only trick that works.

 

So its now out had coolant inside was driping when i took camp off. Thanks for the tip on cutting off bracket. M dub just email me at bovillconstruction@yahoo.com im in Vt back to work. If coolant temp and oil temp is the same by a few degs should be fine ill test that late today at friends garage

Its all back together and seems to have no issues. Id like to know if there is a reason that the turbo has a small hole where they join together. I had to bolt the egr in and keep pluged in but i used block off plate. Oil cooler next

 

Small hole????? do you meen in the joint under a clamp? from the Ypipe to turbo? if so they can be a PITA to get lined up right.
