I don't have any Hot Texas sun here in Washington...just rain does that work? :lol:Best way would probably be pull it and take it the radiator repair shop for a hot dip. Otherwise, running simple green through it, flush it out and put it out in the Texas sun for a few hours to dry it out...
Now you tell me. After looking at the instructions on how to pull the intercooler I think it is just fine. :yesnod: Maybe I need to design a portable flushing system that hooks up to the intercooler and circulates hot water with a detergent through it until clean and then blows hot Texas air to dry it. :thumbsup: Or maybe when the wife isn't looking I'll hook up the washing machine to it and run a couple of cycles through it. :jester:Be careful, you don't want moss growing in it.
Do you feel it is really worth it? Could you notice any improvement in EGT cooling etc.?Its actually not that bad pulling it out.... The hardest part is probably moving the AC Condenser without breaking any lines.
If I were going to pull mine again, I would most certainly bring it to a repair shop, that way they can test for leaks as well.
When I pulled mine out to swap the engine, I cleaned it out with plain old gasoline, followed by alot of water.
Just my $0.02!

To be honest, I changed so many things with my old truck, there would have been NO way to figure out if that helped it any.... Or if the gasoline had eaten any seals and made it worse.Do you feel it is really worth it? Could you notice any improvement in EGT cooling etc.?
I'll probably hold off doing it at least for now. Spring time in Washington isn't conducive to air drying anything :icon_rolleyes: I might do it later during the warmer months or should I say weeks.To be honest, I changed so many things with my old truck, there would have been NO way to figure out if that helped it any....

Sorry I cant give any more information about that.... I only kept the truck for about 3 weeks after I did that before trading it in.
Interesting...I have no doubt there is oil inside the intercooler from the CCV system. I have added a decent CCV filter system that seems to be keeping the oil from getting into the intercooler now but how much is there...I don't have a clue. Like I said earlier when the weather warms up I'll take it out and clean the intercooler up. Doug, is there a method you would recommend to cleaning it up other than putting something like Purple Power in it and then rinsing with Hot Water and letting it dry afterwards?Here's what I have found.
For many years and many miles of driving, the intercooler gets full of oil from the PCV system. The vapors of the engine are routed back up and into the turbo inlet. These vapors condense in the intercooler and end up as oil in the bottom cores of the intercooler. With enough heavy throttle, the rushing air takes most of the oil out of the intercooler and up into the engine. What's left sits in the bottom of the intercooler and blocks the bottom cores of the intercooler. This makes the intercooler smaller and less efficient.
I have gone so far as to add a drain to the intercooler that allows the oil accumulation to exit the intercooler. This extra oil can be drained or routed back up and into the crank case. The point is to get the oil out of the intercooler and make room for charge air.
I take it you have never removed the intercooler and cleaned it? With the CCV filter system I have on now I am not concerned about getting more oil inside the intercooler just removing what is in there now.On my own truck, I took a 1/16th" drill bit in a drill bit extension and drilled a 1/16th" hole in the passengers' side tank. It took about 5min for the oil to find it's way out.
I left the hole open as there is NEVER a negative pressure there, only positive pressure and the boost pressure leak is inconsequential (1/16th" hole is tiny). The hole weeps and gives me a little oily stain on the radiator core support. I don't recommend this for everyone, but it is effective and easy. Whole job took about Min.
When I do it for a customer, I'll take an 1/8"NPT compression fitting and a length of 1/8th" capillary tube. The fitting goes into the bottom of the intercooler and the capillary tube comes up to the oil filler cap. As oil accumulates in the intercooler it is forced thru the capillary tube and back into the crank case.
