Anyone done this before, and how des it compare to the Motorvac fuel system carbon depletion service?

Chris

 

I will be willing to bet it is just something that they add to the tank. You could buy something better at a autoparts store or from amsoil..

The only one that I have seen that works is the ford fuel system cleaner. It hooks into your fuel rail (because the cleaner will eat away your tank) and you run the engine off of the machine for 15 minutes.

 

It's three parts:

1) Additive is added to the tank of gas
2) Throttle body cleaner is sprayed through intake tube and throttle body
3) Another cleaner is added as you mention that cleans the carbon out of the engine, which causes a lot of smoke to exit the exhaust.

This sounds identical to the Motorvac system to me, and it's cheaper.

Ok I see. When I worked at Firestone, we used the same thing make by wynns.

The throttle body you can do yourself as well as the fuel tank additive. The "carbon deposit" cleaner is just a bottle that they hook up to the vacuum line on the master brake booster. If you can find a place to order it, you will be able to do it yourself cheaper...

 

I would need to know exactly where do attach the bottle to be able to do it. Anyone know?

Chris

 

On the master brake booster (behind where you put the brake fluid) you will see a big vacuum line. If you take it off the truck will run very rough. You hook it to that line and it will suck it in. I believe that people do this with water and transmission fluid to clean out their engine. I personally wouldn't use those...
Here is a pic that I have on file

There is a vacuumm line to the left of the fluid tank (if you are facing the engine like in the pic)

 

Do you have any way of highlighting it, so I can tell which one?

Chris

 

I will take a pic of the hose when I get off work tonight..
You can't see it very well in that pic.

 

Thanks man!

 

Be very very very careful about using your vaccum hose to pull any type of fluid into the engine.
It has been discussed here before, and you can destroy your engine if you get too much fluid into any cylinder and cause it to hydrolock.

I would use a smaller vaccum line, or dont do it at all.

 

True, I'm mainly trying to find out who is better, Jiify Lubes Deal or Motorvac for almost double the price.

Chris

 

Well yes and no. It won't hydrolock your engine if you use something made for it. If you use the tranny fluid and water, it will increase the risk of hydrolocking the engine.
