Hey i just bought a used drag turbo kit from my friend, he blew his gsr motor but the turbo kit seems fine. I was just wondering if thier should be any oil inside my front mount intercooler? Or do you guys think its there because he blew his motor, maybe thats why there is oil in there. If so how could i clean the inside of the cooler then? Any anything else that could be useful or any help would be great. thanks
