long story short, i am in the process of doing an oil cooler and a egr delete. (fun job on its own) I have the intake manifold off and it is filled with black junky tar. Just a complete mess. I am waiting for the new parts to get here and am wondering what the best way to clean this is. I was thinks of just letting it sit in some simple green for a few days until the parts came in and then pressure washing it all out. Will giving it a good soak hurt anything or am i better off spraying it down quick scrub and repeating until it's clean.


Also gonna clean the turbo while it's off so any tips on that would be of great help but i am looking for answers to that currently.
