I'm suspecting a large build-up of carbon in my intake manifold...and i want to clean it out...what do you guys think is the best method of doing this???

 

I took mine off and sprayed a whole bunch of cleaner through it.

 

the manifold on:
spray TB cleaner...run engine
OR
do that top engine cleaner thing where u dip a vacume hose into the cleaning solution..etc etc

the manifold off the engine:
simple green or castrol super clean
use a wire brush


best is to do it w/ the manifold off the engine.

 

thanks for the input guys...I think I found an easy way to clean it a little bit at least...I just pulled my PCV valve out of my valve cover..still attached to the little hose...and it was really oily and sooty..so I took it off the hose and sprayed it with TB cleaner and got all the gunk out of it...I then re-inserted it into the hose and turned on my engine...I had my friend rev my engine to two grand...and I sprayed TB cleaner through the PCV valve until the can of TB cleaner was gone. I'll have to go take it on a test run to see how it worked.

 

get a wet NOS kit that will lean out all that gunk.

 

Brian you want your top end back?
















































sell your UDP

 

d@mn you!

oh, I'll get my top end back...as soon as I clean my darn manifold all the way...

 

You need your top end AND low end back, so automagics dont pull on you from a standstill

 

OUCH

I usuaully just spray a full can into my TB but if you check that thread out, there is a better way. You will also clean out teh EGR valve and prevent any problems down the road.
