Help needed. I think someone put mine up side down. Need info.
You need to remove the oil filter then the cooler to inspect the seal. When installed properly, the seal is sandwiched between the oil cooler and the engine block. The seal attaches to two tangs on the oil cooler to keep it in place when you are installing the oil cooler to the engine block.
To remove the oil and oily residue from your engine's cooling system, you need to fill the system with water and add a cleaning agent. I've been trying Simple Green in my system. However, you may use any type of detergent as long as it is low sudsing.
Currently, I'm using two cups of Simple Green in my system.
New problem changed the oil cooler and put some dawn soap. But now there's black smoke when its too lean and white smoke when its on the rich side. Is this normal? I was thinking its burning the old milky oil. And for some reason my blow off valve has I long high pitch now. Lmk thanka
Now would be a good time to post up a complete mod list, as well as your definition of "rich", "lean", and a better description of the amount of smoke.

I can't describe what I got internally cause I got it used. All I know is that there's a Turbo system and a computer w/LCD programmer inside the car and there is also another a switch to control the gas and air mixture. Other then that Idk. I wish I built the motor so I had more understanding.
