Cleaning filthy intake and throttle body + Caligula's warm weather delete

Here's what i did today.

First took apart the intake, discovered how horribly dirty the back of the throttle body and the manifold is. I have a new PCV valve to keep this from getting worse, but anyone have a good way to clean the filth in the manifold without taking it apart?






In seeing the ICV having these coolant lines flowing through it, i decided to do the Warm Weather delete i did on my M3. It was much easier then bypassing the two coolant lines on an S50 engine, i just took one hose and plugged it into that round thing. BTW, what is that round thing?

 

If your going remove the intake there's a fuel filter under the manifold...I believe. Might try Amsoil power foam and see if that helps.

 

Just curious... what do you plan on gaining by doing this?

Thanks.

 

Cooler intake, about 0.2hp.

 

I did the same thing a few years ago. I had no change in performance. After I installed the Inchworm 4.7 lefty, I re-incorporated it and I noticed the IAC functions while crawling better than it did being disconnected. I do have an A340F it that makes a difference.

Thanks for the reply.

 

Honesty and true knowledge doth this man have!

 

In theory, if i ever needed to remove the intake manifold, i could also remove the round cut off valve and one of the hoses involved, as well as the vacuum tee. Right now i'm just recirculating coolant.

 

Soaked in Seafoam, then WD40. Nice and clean. I took the opportunity to spray seamfoam down all the intake runners. Huge smoke show after i started it up.

 

Me personally? I'm not taking all that stuff apart unless my truck starts running badly and I think that will cure it. I ran some Sea Foam through it when I first got it then ran some Sea Foam in the gas. After a few months I ran some Royal Purple gas treatment through it and then a few months later I switched to Amsoil P1 because I remembered using that in a car 15 years ago and it made a huge difference. I now run Amsoil P1 in a tank of gas about every 4 or 5000 miles and the truck does run better. My thought is that I won't have to take it apart if I keep it clean in the first place.
