Stock Injectors Destroying Engines?

[number5]

So how do you tell if one injector is going bad?

So WHO makes stainless steel injector internals, and WILL they last much longer than OEM Bosch injectors?

Is there a big difference between Bosch vs non-Bosch rebuilt injectors?

I am looking to make my next engine last a little longer than 109k.

Is it foolish NOT to put extra filtration BEFORE the under-hood fuel canister?

Should I install a FASS or some other filter pack on the frame rails? I suggested a Walbro and a couple of filters between it and the engine (a 10 micron and a 2 micron) and the tech said Walbro is junk and won't last 40,000mi, and said Air Dog or FASS are the only ones worth having.

I am now dumping MORE than the book value of the truck into these repairs*, and want a reliable truck that will last the max miles I can get!

Informed opinions please.

BTW, the inside of my engine looked like NEW except for a gouge in the front of #1 cyl and the back of #6 cylinder. No evidence of overheating or stress. Pistons w/ slight black carbon deposits (just enough to color them). Truck was never used hard, and had NO mods at all. Engine ran like a Swiss watch except for blow-by.

They make stainless steel bodies....not internals. Stainless steel is less prone to cracking which is what happens to Bosch bodies under high pressures. People that cap their rails and run pressure boxes will reach upwards of 29,000 psi and I'm pretty sure that combined with a sediment in the fuel is what causes cracked bodies. Brown's Diesel and Wicked Diesel sell stainless bodies I believe. They're in the vendor forums here.

Last I heard Don @ F1 was the only one that could rebuild Bosch injectors? Something about a patent problem and not being able to order parts from Bosch due to their exchange only program. That's just what I heard, not 100% sure on that subject.

I plan on running as much filtration as I can possibly run. If you want to build your own fuel system, a Walbro isn't your only choice. From what I've been reading lately, Walbro's quality has gone way down and I have read complaints from people who have ran them. There are several electric pumps available as well as some mechanical pumps.

If you don't want to build your own system, then go with an Air Dog or FASS. There are many happy Air Dog users on here and their prices are very reasonable.

geeez man, you're really being feed some bad info.

All Cummins injectors are now SS. All 6.7's have them from the factory and if you were to buy new, that's what you'd get. As far as I know, there's only one person actually rebuilding Bosch injectors and that's DonM @ F1 diesel. There's not a lot of working parts in a injector so there's really only so much that can be done to them. Custom tips is the biggest thing most aftermarket shops are doing.

Yes, it is foolish to not have extra filtration. The stock filter is a 5 micron filter and having something extra like a inline 2 micron is smart. Like mentioned earlier, the smartest thing though is to be vigilante on filter changes.

The Walbro is a great pump... very strong and known to last a long time. My truck ran at 700hp with this set up for almost 2 years. You can also see the 2 micron inline. I changed it to go to a Airdog ( second pic ) for even more filtration.





Stick to these forums for better info. It's not always the best but, you'll surely get better info than you have !!

If you have one that is leaking bad you will start "making oil". It will leak the fuel into the crankcase and raise the total level. Most people also see hard starting issues. I've heard some people say their trucks have ran great with bad injectors though. Some people say they misfire like crazy.

What is this?


Why a fuel cooler? Feel free to talk to me like I'm stupid.

If you insist.... it's a trans cooler

I removed my auxiliary cooler and replaced it with that

correct me but the stock filter is 7 micron at best it may even be 10

the stock filters used to be 7 but, changed a while back to a 5 micron.

Ummm...no. Dynomite Diesel rebuilds them, Performance Car & Truck, PDR or an affiliate shop also that I can think of quick. Rebuildign them is easy, testing them is another story and thats a $30k machine to do it correctly.

All you need is $$ and a Bosch Blessing.

I think Garmons just bought a flow bench for CR injectors also.


Now, doing cusotm tips is another realm entirely..........

Dude, you better recheck your info. NO ONE gets blessings from Bosch which is why none rebuild injectors. The most any can do is pull them apart ( and only so far ) for cleaning. Those companies you mentioned are doing custom tips and minor cleanings.

The only way to flow test a injector is to NOT be a authorized Bosch service center. Garmons machine is cool and will do so much but, that's only because he's not a Bosch service center as the others aren't.
