I'm talking about the cleaning where the machine hooked up to your fuel rails. Is this a gimmick or a good idea? I have 114,000 miles on a 5.4. The person I bought the pickup from had the engine replaced under warranty at 66,000 miles. I have the original reciept from the dealership to prove it. It just calls it ENG ASSEMBLY 453112 Part # XL3Z-6006-ARM. Not sure what all would be replaced when this is done. I'm guessing new block, pistons, crank, and heads. I wonder if they reused the injectors. Anybody have any experience with this kind of injector cleaning service?

 

yes when the replace the motor its just the long block. the intake manifold and injectors are reused. so yes an injectors flush would help u out. there is a noticable gain in performance when u get the injectors flushed and they are gunked up

 

I just run a bottle of injector cleaner through the tank of gas immediately before my oil change and address it as kind of an ongoing preventative maintenance type thing.....

 

Yeah I've tried the cleaner in a bottle stuff. It doesn't seem to make any difference. After extensive searching and reading I think the motorvac injector cleaning is the way to go with as many miles as I have.

 

How much does the injector cleaning usually cost?

 

That's a good question. Anybody have this service done?

 

A friend who works the parts counter at a Ford dealership says if you use the Chevron injector cleaner twice a year, you'll be fine. Now if your truck sets around for a while without fresh gas it will go bad I believe but most gasolines now adays are the cleanest they ever have been and with the new detergents in them they keep the injectors in fair shape. If it was me, and I didn't know what the truck went thru its 1st 50K or so I'd probably spend the $$ to do it, and I'd also do the oil flush as well.

 

I'm pretty sure it got the equivalent of an oil flush when they put the new engine in it.

 

i think its 65 bucks...

 

I have found in the past that the type of cleaning where you hook up a can of solvent/cleaner to the fuel rail is far better than adding a can of anything to the fuel. I do my vehicles at about 60k. On my 01 at 60 I had used a can in the tank and still felt the engine was a bit sluggish. Had the fuel rail cleaning done, and it was like a new vehicle again. much better. I am not saying you shouldn't use the fuel additives, I do think they slow down the clogging process, but I don't think they are a cure all for dirty injectors.

 

A professional fuel injector service is worth it, especially in a higher mileage truck. I recommend a Motorvac engine decarboning service. They go in on the fuel line just in front of the filter and force a detergent (not solvent) solution into your fuel system. That not only cleans the injectors but soaks the cumbustion chambers and the tops of the pistons. After about half and hour (let it soak longer if you suspect a heavy carbon build up) they fire up the truck and a cloud of white of smoke blows out. After that, runs like new. Not cheap though, about $150. Motorvac has a website explaining the machine, chemicals used and proccess better than I can, just google it and read on. I plan on doing this every 50-60K but I also run a fuel injector cleaner in the gas tank at every oil change.

 

So is there a difference between getting your injectors professionally cleaned and the motorvac service? From what I could find I thought they were the same thing.

 

Im told I should run some injector cleaner in my truck 195k but I dont like adding all of that junk in the fuel. Ive seen people take four or five bottles of different things and pour them into their gas tank. Im a bit leary of these cleaners, have yall had success with these cleaners?

 

injector additive to the tank dont always mix properly with the fuel and will cause sputtering and whatnot.. for injector cleaning its best to have it done professionally

 

BG 44K has always worked well for me, I have used it in many vehicles.

$20 for a can
