Cleaning intakes???

kdog_x · Aug 11, 2004

I just pulled my upper intake so I could install new fuel injectors and I noticed that the upper and lower runners are covered in oily black carbon crud. What works best for removing this stuff, will it just come back on me anyway? Also, I'm doing this to pass an emissions test, so should I do the extra work and remove the lower intake and clean it out as well?

thanks

Clean the upper with Carb/intake cleaner...lots of it...then you can rinse it clean with water and air dry/compressed air. Spray a rag and scrub the lower runs as far down them as you can...it will help alot...swear I picked up a few pounds of torque when I did it to mine...plus thats less crap getting into the combustion chambers and intot he exhuast. It should help with emmissions (BUT it will come back) best way to slow/stop it is to add a clear fuel filter between the PCV and intake...thats where the oil is coming from. Then just change out the fuel filter every 3 months. Dont remove the lower..you can get enough of it out through the top.

Where did you get the filter you used between the PCV and intake, also did you mean between the PCV and the hose that connects to it? I think I'm gonna do like you said though, I really don't feel like pulling the lower intake cause then I'd have to go burrow a timing light.

I always screw that up...PCV...just get one of those little clear plastic ones at Auto Zone...make sure it will connect to the hose and get 2 little clamps.

They put Teflon in frying pans to keep stuff from sticking, so why hasn't some smart guy figured out a way to Teflon coat intake passages? Just think no deposits stuck to the walls...

Sounds like a million dollar idea to me...

Joe, arent the TB's coated in teflon (hence why people are not to use carb cleaner on them)? you got a great idea, BTW. another job for porting guys: "would you like me to teflon-line your intake?"
