Hey man, I think I'm about to jump forward with rebuilding my engine from my 89. These videos have been a huge life saving reassurance for me because I honestly have no idea what im getting myself into. But, I figure these are helpful enough that I probably could rebuild the thing myself instead of spending the money on a swap. Thanks a bunch
I really enjoyed the video, exact process i followed in the BMW E30 and works pretty nice! I would add the use of a nylon hammer, cleaning the inside of inyectors when open (connector wire jumped) with carburetor cleaner and check the injector resistance to avoid repairing a faulty one.
Glad you liked the video. I actually had them professionally cleaned and tested before, and did the rebuild just because all the rubber was old and brittle. Definitely worth doing a check and clean before rebuilding, I agree with you on that.
Thanks for Sharing! Gotta do this on my Old Toyota Pickup Truck. Was lazy and didnt have a o ring kit when I rebuilt it. Try and get it done this summer :)
You forgot to mention the important part,Clean the internal mechanism that deteriorates due to heat soak and separates the fuel into waxes,parafins and olefin.
Wouldn't you also want to give the injector especially the nozzles a good cleanout with a Carby Cleaner or similar whilst you have the injector out and easily accessible? I intend rebuilding my injectors and will be cleaning them thoroughly - many people recommend backflushing which seems reasonable particularly when the microfilter is removed.
Maybe yah if they look gummy but every injector I've ever rebuilt was clean already. As long as its been running clean gas the majority of injectors are pretty clean. I mean it is gas going through after all Haha but yeah just look at them and if they appear to be clogged or gummy then give them a gentle cleaning😊
Fantastic, great tutorial. Any risk from light wipe with wd40 or cleaner alcohol fluid to wipe over the whole injector,around tip and inside filter section on injector? All the best.
Got a kit coming for my 85 Celica, I was going to order a kit to rebuild my distributor but found some brand new dizzys at a great price on RockAuto so went with that option. I will keep the OEM dizzy though and might rebuild it at some point
Hi. I have an 03 cadillac deville. I was following these steps best I could with what I had based off my injectors. I could not remove my pintle caps. But even worse I tried to remove my filter baskets using the screw method. DID NOT WORK! I destroyed my injector because part of the filter is still stuck inside. Not sure if any debris fell inside injector. Do I just replace the one injector or replace all? Also do you have any suggestions on removing the fuel baskets on my 03 cadillac deville. Thanks
Yes, if your injectors are good. You can also clean the injectors. One main reason injectors do not function correctly is the filter becomes clogged or the injector's spray becomes compromised from clogged ports. If the injector isn't spraying properly the fuel does not get atomized correctly thus reducing performance or may not spray much at all. You can clean the injectors using carb/choke cleaner. There are videos of people showing tips on how to do it at home or you can take them to a shop for cleaning. If you are doing it at home you can remove the fuel rail and test them. The easiest way to verify if they need to be cleaned is after removing the fuel rail, connect the fuel rail to the car's fuel line and insert each fuel injector into the fuel rail. Connect each wire connector to the fuel injectors. Now place the whole fuel rail in a position to keep the angle of the spray away from being directed towards you, possibly spraying into a cardboard box. Have an assistant crank over the engine while you watch the fuel injectors spray, maybe record them spraying. You will be able to see if the injectors are clogged at all. If your vehicle hasn't had the injectors serviced, buying the kit above isn't very expensive and is a good service to perform especially on an older vehicle. My son and I just did this on a 1986 Honda Accord. It only has 50,000 original miles on it but when we removed the injectors to test their spray, the o rings were crumbling in our hands and we noticed some of the o ring material has crumbled down inside the injector so we blew it out. We mainly wanted to check the spray because the fuel in the car had been in it for three years and may have gummed up the spray nozzle. If you can, if your car is running, try buying a quality brand fuel injector cleaner that you add to your fuel tank at the same time you get at least half a tank of gas. Pour the additive in the tank then fill up with gas to mix it up well. Drive the car until your low on fuel again so the additive has time to clean your injectors. Then try the method above. If they are still clogged, google some simple ways to directly connect the carb/choke cleaner can to your fuel system to clean the injectors. It isn't hard and basic tools are sufficient.
Matthew Barry I had mine ultrasonically cleaned. It's great for getting gunk out. Probably better than a DIY flush. But any sort of flush is definitely a good idea.
My car has done 125,000 miles and I did this to my injectors but I regret doing it because the filters were completely spotless no dirt in them at all if aint broke dont fix it.
I got a kit from www.theinjectorshop.com mine was for the 22re but I’m sure they have one for the aw11 as well or whatever engine you need. I paid $12.95 usd and the kit includes 4 micro filters, two styles of pentle caps, and the o-rings grommets and spacers. I’m ditching the aftermarket orings in favor of OEM ones but the micro screens and pentle caps aren’t available through Toyota so gotta go aftermarket for them.
its been sitting for 3 years but started first kick and ran well till I put my foot down and started to piss fuel on the rear injector seal so I have to pull I down and re do the set. thanks for your video it has helped a lot

thanks dude, I just installed mine and they fit perfectly. Best way to install those caps is push injector and cap against table it pops to in place. No need to warm up.
Hi! Im roger from the philippines and i have a honda crv 2003 model. Can u put a video on how to dismantle its fuel injector and what is the specs of the honda crv fuel injector? Tnx.
Except these are 30 year old cars with 30 years worth of crud in the gas tank and the fuel filter only Does so much to keep particulates out. Since it’s a pain in the ass to get at the injectors on my 22re Toyota I wouldn’t risk that ... most Toyota’s that use these old Injectors have an upper Intake plenum that wraps around the fuel rail with a load of vacuum hoses and coolant lines blocking access to the injectors and blocking access to the fuel rail bolts so personally I’d just do it right once and forget about it rather than risk having to disassemble and buy a new gasket for the intake which costs as much as the entire rebuild kit for the injectors with new micro screens :)
