Re: fuel injectors

Injectors are usually very reliable..Can get spray patten/ flo rates checked...
But generally imo you are putting money in some one elses pocket...
Can take out and clean pindle etc yourself...

Re: fuel injectors

Many years ago, when I was a lad, and computers had not been invented yet, there used to be such a thing as a "technical pen". These things used to be used to do engineering drawings and such stuff, and used to run on Indian ink. When you left the pens for a week or so without the tops on the ink would dry out and gum up the pen. We then used what was called an "ultrasonic pen cleaner" that ultrasonicaly (der) broke up the ink and refreshed the pens. Guess what? It also used to work really well on injectores, especialy Jaguar ones. It was a bit slow though, cos you usualy could only do one or two at a time, and on a V12 that took FOREVER! I don't know if these cleaners are still available. I do know that Ultra-Tune have an injector cleaning system that seems to work. Pour - in injector cleaners really only get rid of the looser stuff, and not the varnish. I would probably say if your engine has done over 160k you need to have a good think about the efficiency of them. A crowd in Ringwood (Vic) called Powerflow have reasonably priced replacements.
Anyway, thats my 2c worth

Re: fuel injectors

Can injectors physically wear out?

Re: fuel injectors

You can still get the ultrasonic cleaners, $200 - $400 or so (sometimes cheaper).
By using one of these, with cleaners, you can do an ok job on them . . . Although I think you really need a pressure bench to do it 100% (i.e. able to hook em up and check flows / patterns etc).

Depending on where you go, you can pay a fortune for remanufactured ones ( I was actually quoted $300 *each* for OEM Ford ones at one place). You can get them much cheaper from the USA (US$220 should get a set of 8 FMS injectors).

Re: fuel injectors

I'd only get them cleaned and tested when there is something noticably wrong with the car.

I was told to run a tank of PULP and see if that improved things, as my first EB had a range of 300kms a tank. It didn't improve, so I had the injectors pulled out and sent them off to be cleaned and checked. 2 were okay, 4 would not come good. The 4 duds were replaced and my fuel economy went from 300 around town to 500 around town.

'67 Mustang V8 4sp... what fun to drive!

Re: fuel injectors

^^^ Lol, thats probably the best point :)

Unless you've been using bodge fuels, or have been unlucky, its unlikely they should be clogged already. You can also give one of the injector fuel additives a go... (something I should give a shot myself )
