I am in the process of replacing my fuel injectors and cleaning around them is relatively hard. They are hard to get at and get completely clean around, so far i have used degreaser, citrus cleaner, and air pressure and now I have it fairly clean around them but all the dirt,oil, etc is basically mud now, not pretty and still too close for comfort. What's the best way to get rid of all that junk? i dont' want any of it falling in when i take the fuel rail off. I dont' really think using the hose on it is a good idea but it seems like the only option.

Use a garden hose to spray your motor down,
but instead of using cold water,hook up the hose to a hot water source.Cover the intake
(throttle body) and distr. and spray it down.
The hot water REALLY HELPS get all the grease and grim off.

Here's another thought, but for after the rail's out. When I did my injectors, I blew the area out under/around the rail with compressed air. When the rail was out, I cut up a rag into 6 (I have the V6, heh) little lonnnng pieces, and wedged them into the holes for the injector. Then I used a toothbrush to loosen the rest of the dirt, and blew it out with compressed air. Then I yanked the rag pieces out. Just don't let the pieces fall in!

Try using some pipe cleaners or Q-tips to get in those hard to reach places.

 

Thanks for the ideas I was a little hesitant to take the garden hose to it but I figured as long as i kept it out of the engine and off the distributor i would be ok, hot water duh I never would have thought about it. Thanks again should have that sucker squeaky clean!

You can get the diesel fuel in a spray can type cleaner, like Gunk Engine Bright or Auto Zone brand; drive it to the quarter car wash; wait a while for it to cool down some; soak the engine down with the cleaner and let it soak, then wash it with the car wash. You should be able to get it looking nearly like new.

The garden hose works too, but the car wash works better. The diesel fuel is the key.

No don't use diesel fuel to loosen any gunk on your engine. The effects are extremely harmful. All your wiring looms and wires will harden and up crack. It ruins plastic by completely drying it out. I know this from experience - I used to have my jeep's undercarriage and engine bay steam washed and the attendants there would spray it with a mixture of diesel and detergent to loosen the gunk. it basically ruined all the wiring and fuel lines by hardening them.

Interesting... I've been doing exactly as I describe for decades, no problems.

You could carefully spray carburetor, or brake cleaner around the injectors and very quickly spray it off with compressed air to keep it from causing any harm to anything. You typically won't hurt anything under the hood, but some plastics are sensitive to the stuff. WD-40 also works, and I use it to track down vacuum leaks.

I hook up my hose to the hot water heater and let the water get good and hot almost like steam then adjust nozzle. I have never used any cleaners on it since I am original owner of car I have always done this every once in awhile to keep it clean.
