Had my car serviced today...question about "fuel induction system service"

[wuzzzer]

Well, my car rolled over 60k miles recently. When I took it in to the Ford dealership for an oil change, I decided to do a PS fluid flush and fill, and coolant flush and fill. They also replaced a turn signal light bulb.

While I was there, the service tech tried selling me on a service/product they call "BG 44k" which is part of a fuel induction system service/cleaning.
What's everyone's opinion on this? It sounds pretty invasive to the top end of the engine, as they open the upper intake plenum and hook up a machine to it and clean out the intake. Cost is $94.15. I told them I might do it at my next oil change. I do frequently use STP gas treatment and products like that every 5 tank fillups or so.
Let me hear what you all think!
On a side note, when they called me at work to tell me my car was finished, they said my car was too low to run through their automatic car wash. They had to wash it by hand. Hand washing=good thing. My car always looks semi-clean after they use their automatic washes. It looked GREAT after they hand washed it!

I'll run a 'dustbuster' over your air cleaner and manifold for $79.00. thumbs_u

Wuzzzer, I am taking my SHO in this week for 45000 mile routine maintenance. I will check to see what the deal is on it here in Memphis. I have known the Service Advisor for a few years..maybe he will shoot me the straight scoop.

What they are trying to do is to suck up the condensed liquid oil thatr hs pooled in the surge tank. This pooled oil really desn't do any harm other than reduce the volume of the surge tank. It is the oil that is vaporized and condenses on the valves and IRC butterflies that does the damage. IMHO no amount of $94.00 sucker jobs would do much good.

The carbon on the valves and butterflies should only be removed by disassembing the componets and then cleaning or you risk inhalation of hard carbon particles into the motor.

I have 3M's FI cleaning system which uses a pressurized can of solvent fed into the fuel rail. Won't do squat for anything before the FI as far as cleaning. The other thing they use is a solvent in a fogger type spray that is put in the TB while running. I can't imagine that it would mix with the oil and allow it to be burnt off if this is done with the motor running.

You might try to add a carb cleaner spray into the surge tank through the various ports when the nmotor is off. If a couple of cans were sprayed in and it was allowed to pool with the condensed oil for a couple of hours or overnight it would mix. Then start the car and spray some in the TB while running it. Change oil afterward.

The best way is to just remove the surge tank and manualy clean it. If you just tip it on end overnight then spray it out in the moring you will get it pretty clean.
