Hi.

The replacement OEM's are no longer problematic - by now, all of the suspect injectors from that specific supplier that made the bad lot in 2005 are out of the supply chain.

Yes - injectors are expensive - but they are crucial, so it's best to get quality. And the correct size, of course.

I do not trust anything with the Accel label on it. Or Dorman. You however can do what you wish - it is your truck.

It's the whole "leading a horse to water" schtick .

good luck

When I found out how many lbs stock was. I'm now looking at smp and motorcraft. To replace faulted ones and clean others and rail.

MGD

At least do a leak test.

Not replacing all of them is just false economy, in my view. All it takes is one original unit to leak and you can kiss yer cats - and possibly yer engine - goodbye.

You really cannot clean them effectively - yer wasting yer time trying to do that yerself.

I've told you my recommendation for replacements.

BTW - if the gas was 'black' only on the inlet side of the filter yer fine.

It was clear (or color of gas) going into filter but exit towards motor is where it dumped black.

I figured id replace the injectors. And clean the rail. Thanks.

Anything else should be checked while its all off. Oh yeah to disconnect the gas line from rail is it same tool you use for gas filter?

IMO I would run the original injectors right up to the time/mileage limit of the extended warranty. Ford chose not to recall these, knowing their potential for catastrophic engine damage. Even if you have one bad injector, Ford will not replace the rest- only the one that is bad. Ford is taking a chance that the injectors will not fail and hydrolock your engine. I won't pay to correct Ford's faulty part when there is an extended warranty that will get you a new engine if the injector fails stuck open. As soon as the extended warranty is up via time or miles, I would be replacing all the injectors before I drove the truck again. Of course, if you have some driveability problems, then it's best to replace them (assuming they are the cause). Still, take it to Ford and see if they will test and replace the problem injector(s) under the extended warranty first. I had my #5 injector replaced this way @79K miles. It had not yet caused any engine damage. The dealer determined the rest of the injectors were fine. So, if one of them fails while still under warranty.... the injector and any damage, up to and including a new engine, is on Ford's dime.

Why is yours no longer covered? Mileage? In that case, I wouldn't drive it again until I got them replaced. Replacement engines are expensive, and new injectors are cheap insurance by comparison.

Yeah mileage is why on mine. Warranty was good till 120k and I'm at 182k

I would advise not to drive the truck only if you are having issues with the injectors. If the truck is running fine then there is no reason to assume the sky is falling with regards to the injectors.. I do agree with changing injectors when necessary, and proactively getting rid of the recall injectors. But I would not consider injectors an extreme necessity when it comes to regular maintenance. A bottle of techron every 2-3k should keep them working good, alongside fuel filter changes.

Injectors are solenoids, they either work or they don't. Open and closed is their only operation in conjunction with a spring. If the integral injector filter gets dirty then it needs to be cleaned. This can be done with fuel system cleaners like techron or seafoam. Or on the bench with household items.. Like demonstrated here:
There are slight improvements in modern injectors where atomizing fuel is more "complete".

The injectors I pictured previously with the 6 holes vs the stock 2 hole injectors will likely aid in an even smoother idle, for my specific "supercharged" application. So yes there are benefits and improvements to be gained, but they aren't drastic.

As far as OEM injectors.. I've heard 19# , 22#, and even 24# are the sizes as far as stock goes. I'd go with MGD's answer on the stock injector because I've never truly known which injector the stock 5.4 3v has officially used. To be honest, I still don't know. I'm sure variances in flex fuel models may call for a different injector as well.

Hope this helps..

The only reason I suggest replacing them immediately when the warranty is up is because you never know when one will fail. It could fail stuck open when you shut the engine off. The next time you start it you could end up with a bent rod and need a rebuild. It could fail the same way driving down the road. I'll take the chance as long as it's on Ford's dime. Once the warranty is up, they are getting replaced.

MGD

The problem is, one injector may initially fail and 'only' take out a cat on one side. No other effects other than dumping raw fuel into the crankcase and some cylinder wall-washing.

So - you wave yer letter in the Service Manager's face while logging yer drivability concern - Ford replaces that injector and the cat and you get a free oil change.

No new engine - and that sword (well actually seven l'il swords) is still hanging over yer head. It could happen again. And yet again. No hydrolock - just random failures. Meanwhile all that repeated raw fuel-diluted oil is extracting it's own unique pound of flesh from yer engine. At what point do you say 'enough'?

As you say - replacing them proactively is cheap insurance. I would not count on a hydrolock. Besides - this forum and others have their share of unfulfilled hydrolock events where Ford has refused to remediate the terms of the Letter. Leaving the owner holding the bag. Totally avoidable. Heaven forbid you DO get a rod through the block - in the middle of bumfek-nowhere, towing yer depleted camper, with a truck full of kids and one pissed-off DW. Will showing HER that Letter save yer life?

Side note on injectors:

I called my local SVT dealer - the 5.4 3V's use a 24# injector. As for FF vehicles, the injectors have different part numbers & the fuel pump is bigger (e85 requires higher flow rates than E10).
