Doesn't Techron work to clean off engine deposits ?

Chevron Techron is supposedly the best fuel system cleaner. Meaning it will clean any place where fuel touches. The problem in DFI engines is that the fuel is spraying directly into the combustion chamber,thus never reaching the valves.

Bummer thanks ...

Please take my money, where do I sign up.

That's why you perform a cleaning through the throttle body/intake manifold, and it cleans valves. Several companies offer the product/kit. It works.

Literally, spray into throttle body/intake manifold, takes usually 10 minutes, then let car idle for about 10-15 minutes. Easy peasy.

For non-DFI, it's not really needed, normal BG-44K/techron works fine. DFI needs this additional step.

I'm looking forward to taking mine apart to see how to reach the engine and throttle body... How often would we need to do this work?

Alex,as BGB has mentioned,we should probably not be concerned with this at the moment. It remains to be seen if this becomes a problem in the future.

thanks

Sorry I couldn't resist. I know it was just a simple typo.

Apologies not needed, it was funny. Thank you for all the work on the Database.

BG or the similar Seafoam won't be able to remove the baked on carbon that builds up on the back of the intake valves and surrounding area, only mechanical action (walnut shell blasting, or tie wraps in a drill chuck) can do that.
This is done with the valves shut to the particular cylinder that is being cleaned, so none of this diamond hard debris can enter the piston area to cause scoring.

Reputations are made and destroyed in the blink of an eye. Now introduce internet hyperbole....

We should allow this vendor thread to remain on topic and you gents can take the DFI discussion to the appropriate forum.

I had typed a reply 3 times that said the same thing but I didn't want to get OT. I think I do want to add that Nick became one of my new favorite forum guys given how he handled this whole thing and I will always be available to answer any inquiries for him. At the end of the day I'm concerned about a photo that came from me that preceded a bunch of concerns over DFI technology when I do everything I can to maintain my positive relationships that have allowed me to source engines and parts. That's all. Reputations may not be ruined in a day but once something is online, if read out of context, it can snowball. Forums allow the snowball to get bigger and bigger and no one knows how far it will actually roll. (Pardon my terrible analogy but you get my point.)

NOW, to get us back on topic, I had a nice long conversation with a longtime friend and tuner last night about my goals of reaching 475 crank HP and he was offended by my low expectations as to what can be really be possible. I sent him a set of 997.2 cylinder heads a year ago to have done and the results are staggering. The more time I spend on things like the X51 and the stroker the more great ideas are hatched for things like cutting edge head porting and having him make me a proprietary manifold that will allow us to fit the x51 with zero modification. With the addition of the cams he wants to make, he told me that BEFORE the displacement bump from the crank, 480 is easily possible. I honestly can't even type what he really quoted me because I don't believe it myself and you won't either.

I'm going to get some scratch off tickets with the hope of winning enough money to take off work for 30 days with no additional responsibilities BUT building a 500HP GT4. I realize I'm never going to win the power ball but i just need to pause long enough to move back to the front of Cayman HotRodding 101.
