Im putting a new gasket on the upper intake plenum on my VE. Its off right now and it looks like the lower and upper intake could use a little bit of cleaning. I was wondering if its safe to use intake/fuel injection cleaner and maybe a tooth brush or a lint free towel and scrub what i can reach clean? I don't want to remove the lower intake. Is it ok to spray intake cleaner into the lower intake with it bolted to motor? if so how much is safe?

I was thinking of spraying a lttle at a time and scrubbing with a lint free towel. If it is ok to do, anyone have any good methods or tips for me? Thanks

 

Throw it in the dishwasher..

 

im assuming your talking about the upper plenum, would that really work? or are you me

 

lol, really, the dishwasher will clean one out really nice, i would wait until the wife/gf is out of the house before sticking it in the dishwasher..

You can also use carb/throttle body cleaner also, get about 5-6 cans of the cheapo autozone carp cleaner, then spray the sheit out of it.

Brake parts cleaner will also cut the grease/grime nicely..

 

now what about the lower intake? I dont want to take that off because it looks like id have to pull the fuel rail which means i would new new injector o-rings, not too expensive, and a lower intake gasket which is around $40-50

i was hoping i could clean that while on the car as long as i dont overspray in it


Edit: nevermind, I wouldn't need new injector o-rings..new insulators would be a good idea tho.

 

Yes, you can clean out the lower intake without removing it, just use some carb/tb spray and an old toothbrush, i don't recommend it, too much crap will be washed down into the combustion chambers.


lastly, yes you will have to pull the injector rail to remove the lower tb.

 

thank you greeny. i will have to try that dishwasher trick if i ever have to pull the plenum again
