Where does the intake side carbon build up come from? I recently addressed a carbon build up problem on our 1998 Dodge Neon R/T with the 2.0 DOHC engine. The throttle plate was sticking after being p

Just got done pondering this question myself. Have concluded the "carbon"--which is downstream of the throttle plate--must be coming from various vacuum inputs to the intake manifold, probably 90% o

Well, that's what I always thought, but it seems that the crud I got from around the throttle body was upstream of where the pcv and egr gases come in. Does it blow backwards up the intake? Build up

I have the same problem with my '96 Ranger ... have to clean around the throttle plates every 15K miles or so to keep the throttle from getting sticky. I'm not a physicist, but from what I know abou

Correction: I think the cloud chamber experiments start by creating a vacuum in the chamber with some water present then when ambient air is admitted (rapidly) the cloud forms. At any rate, the rapid

The more I think about it, the more logical it seems the buildup is a of blowby gases and some of the activated charcoal (carbon) from the vapor recovery system. It ends up in the intake system since

IMO that's part of it, but also if it's an area that gets hot, the stuff gets 'cooked' until eventually (mostly) carbon is all that's left. It's possible some 'fines' are getting sucked out of the c

One great example of this is on VW TDI's. I've seen a TDI intake manifold that was ~2" stock restricted down to ~3/4" because it was full of carbon. In the TDI case basically soot from the combustion
