How we clean and test our gasoline injectors before we reinstall them in our engines

[@gracepeschel3894]

Seeing the porter in the background using the floor cleaning machine tells me that you have a 1st class operation. If you take care of your physical building like that, then your customers know that they will be treated just as well if not better. The automotive repair industry needs more owner operators like you!

[@Jerryattrickliverspottedhands]

That’s how it was at the Cummins I worked for. Every bay had the exact same layout. Trashcan, mop, fan, main toolbox, roll cart, engine table (made to hold cams, pistons, head, etc), parts wash machine. You were expected to arrive to a clean bay with everything in place and expected to return it at end of shift with a floor scrub session at end of shift. Place was immaculate. The doors were roll up glass/window doors, every quarter the shop would spend a day washing them. Good times. Only thing I miss about the place was the work environment.

Indeed. I worked at a local shop, that didn't have one. It suuuuuucked cleaning the floor by elbow grease. Only to see a mechanic make a colossal mess on the floor. Worked at a dealership and had a larger floor cleaner. They likely are using a Tenant floor cleaner. The one I used I see my local mall using. Which is a Tenant T7.

[@benlondon8467]

I’m surprised you didn’t flow test the injectors before you Ultrasonic cleaned them, personally I like to do it that way, then I know if the injectors have been bad flow rate, bad spray patterns etc, Then clean and see if Injectors are now the same flow rates across the lot. I enjoy your program 👍

[@2nickles647]

Really doesn't matter sir. It's the end product that's important. I few millimeters off is not good enough. He wants them to be equal. That's quality. I've owned my truck for over 21 years now. Still has the same old injectors. I don't know why people buy new injectors. Their vehicles develope an engine miss. They start shooting the parts cannon to no end. Some guy says. It maybe this?. So they try it. They spend $$$$...but they don't want to spend time and money for a proper diagnosis. An excellent Tech who knows what and how to diagnose is hard to come by.

[@benlondon8467]

@@2nickles647 it does matter, because as quality Tech, then I know if the injectors were indeed bad, real bad etc, if they flow perfect based on my saved data from previous vehicles I also know the injectors possibly are not at fault. I’ve been an Automotive Elec/Mech, EFI Tech for 36years, still do it every day. I agree with diagnosing problems, not just fitting parts till the problem go away. Keeps my customers richer & me happy. I like to know the reasons why, and I’ll put in serious time & effort to get the best results possible.

This is great and I wish the shop I used had an injector setup but I ended up sending my off for flow matching and balancing. The oscillating sound of injectors makes people thing their engine is failing but you get used to the sound after a while.

[@danielrose-tt7os]

This is a "fit" when performed on injectors that are to be used on an engine that is being sold complete with injectors. Try selling this job to a customer as a "fix" for a problem (and then try and selling further work when this step does not fix the problem.) Injector cleanings seem to be easier to sell as maintenance rather than a fix. None of the Dealerships I have worked at ever had such a machine. The closest thing I can recall was a simple pump and gauge type tool intended to be used on full mechanical (is mechanical the correct word?) injectors used with the Bosch CIS injection system. I know that some people like the CIS injection technology but I was pretty glad to see its use discontinued.

Is there an upgraded version of that machine that can precisely measure the amount of liquid per cylinder during the draining phase? It seems that would be more accurate than eyeballing it, and allows the tech to automate the entire test cycle and read the results at the end.

Dave u think two injectors can throw more fuel then two drilled jets nitrous nozzle or no jets for CNC 30 liter V8 roller bearings in cam n crank ceramic on solid block

[@MasterX767]

In a BMW, the fuel injectors are a serious issue. If one cannot properly clean and service them, your going to spend over $1,200 minimum. Not to mention, you'll need to code them too. I used an ultrasonic cleaner with Heavy Duty Sea Foam for over 2 hours each. Allesun makes an inexpensive injector pulse and tester that you want to activate while they are in the ultrasonic bath. Saved me over $1,000.

I’d be curious to know if you moved injector 5 and 7 to say 1 and 2 and checked if the problem went away. If it did, the cleaning stations for 5 and 7 might need recalibrating or something.

[@99APB77]

Dave, I want to take your suggestion to change the oil in my vehicle twice as often as a manufacturer recommends. I have a 2013 Porsche GTS with 125,000 miles; the manufacturer recommends changing the oil every 10,000 miles. Assuming I go forward with changing the oil every 5,000 miles, do I need to change the oil filter at the same 5,000 mile interval? I have a Fumoto oil drain valve installed, so it’s very easy to change the oil. It’s a lot more work for me to swap out the filter. But if you changing both the oil and the filter. Every 5000 miles is the best way to extend the life of my vehicle and avoid maintenance/repair catastrophes, I will take your advice. Thanks, Austin in Nashville, TN

Just a simple question. With the labor cost of all that testing would it be cheaper to simply replace them all. I'm assuming that piece of equipment is very expensive.
