Jon89le Posted September 15, 2002 Report Posted September 15, 2002 All along the runners of my lowering intake manifold i have black crap which looks like carbon buildup. What can i use to get rid of this stuff? I tried a degreaser and it didnt work. I also tried WD40 with no sucess. I would really hate to put the motor together with all that buildup on the runners. Thanks Quote
GnatGoSplat Posted September 16, 2002 Report Posted September 16, 2002 I think GM Top Engine Cleaner is designed for this purpose. But if you have the manifold out, lacquer thinner gets carbon out. However, it requires manual rubbing to get it off. Quote
91GranSport Posted September 16, 2002 Report Posted September 16, 2002 You can also try using kerosene or varsol. They work well in cleaning up all that carbon, dirt and grease in your engine bay. Just don't let that stuff touch the paint and you might have to let it sit for a while. Also try using a pressure washer. Quote
per0781 Posted September 16, 2002 Report Posted September 16, 2002 like shawn said GM top end engine cleaner is definitely the way to go. Paul Quote

per0781 Posted September 17, 2002 Report Posted September 17, 2002 procedure on how to use gm top engine cleaner http://www.60degreev6.com/index.php?p=pages&pid=38 Paul Quote
Jon89le Posted September 17, 2002 Author Report Posted September 17, 2002 Oh sweet. So i should just put the intake on now and then use this once the cars up and running? Quote
per0781 Posted September 17, 2002 Report Posted September 17, 2002 yeah put everything together on the engine, and then follow the procedure. the vacuum hose i used was the one in the middle on top of the throttle body. It has to be a vacuum hose that was constant vacuum. Paul Quote
MotorCityMike Posted December 4, 2002 Report Posted December 4, 2002 Clean it with BRAKE PARTS CLEANER. It will taks anything oil based off safely and cheap too Quote
DOHCRagtopguy Posted December 4, 2002 Report Posted December 4, 2002 If you still have it apart, try some CRC Clean-R-Carb or Brakleen, it'll clean it up nice as can be. Quote
RedZMonte Posted December 4, 2002 Report Posted December 4, 2002 Clean it with BRAKE PARTS CLEANER. It will taks anything oil based off safely and cheap too Thats exactly what i would recomend. then once its together then run the Top engine cleaner. RedZ Quote
