Street Reeper

Alright I did a search and did come up with some ideas. I want to clean the carbon out of the intake manifold. A lot of people say just to take the manifold off but I really don't have 6 hours to do that. It seems the chemicals most reccomended were BG which a whole sale supplier is right near me. What I have heard to clean the manifold is to route a hose into the intake (after the MAFS) and spray the chemical while gunning the motor (via the throttle cable) and expect to see a lot of black smoke coming out of the exhaust (the carbon that has been broken up.)
I also saw that some people reccomened changing the oil right after doing this, what are your thoughts? I was thinking about re-installing my midpipe, disconnecting the crank case ventilator hose (where a breather filter could go) sticking the hose connected to the BG checmical in that hole in the midpipe and cleaning as per the instructions above.

So really my questions boil down to

1. Is it worth using a chemical treatment to clean the intake manifold, and if you can't take it off you shouldn't bother no matter how bad the carbon build up (87,000 miles.)

2. Do you reccomend BG products or is there somthing better?

3. Should I wait to do this when I need to change my oil, and change it as soon as I'm done?

Thanks in advance.

1. Its not worth it.

2. Its not worth it.

3. Its not worth it.

You only have 87,000 miles on your car why would you want to do that. I never heard anyone having problems with the VQ due to a build up of carbon in the intake manifold. What you can do is rev the enginge to red line a couple of times and that will help to clear up any build up carbon if any.

I had 90K miles when I put on my VI. There was a bunch of build up in there.

To tell you the truth, when I took my manifold off and looked inside, that stuff won't come out with just a spray of throttlebody cleaner. I sprayed what I could out of mine and took a screwdriver to the EGR valve. That was just nasty.

Thats what I was afraid of, did any of the carbon seem to come out with the chemical treatment. Do you think that it would have loosened it up enough that increasing the throttle would have sucked some of it out? I heard that when you do this right a ton of black smoke poors out of your exhaust, so I would think it would be helpful.

Take it off and clean it up real good. Then keep it clean by spraying it with TB cleaner while the car is running every 6 months.

..............and don't wear white sneakers like i did.


Street: The cleaner will loosen up the crap lining the EGR inlet on the manifold (I didn't even bother touching the EGR valve itself because I didn't want the crap to fall inside of the valve) but that stuff is oily and sticky. As long as it sticks to the manifold, I don't see any worry.
