Home brew injector cleaning - Toyota Nation Forum : Toyota Car and Truck Forums

Gear Dog · 05-24-2005, 01:37 PM

Geius Maniacal posted the question in anopther thread and I thought it would be better in it's own. I pulled this from another forum but never tried it. But I have some spare parts in the garage and I'm going to give it t try.

I made up an injector cleaning setup by taking an injector lead off of a scraped wiring harness (yeah, I know that doesn't help you much, right?) and wiring it to a momentary on type switch in series with a 9v battery lead. I got a cheap garden type pump sprayer and some fuel line that fits snuggly over the end of the injector. I fill the sprayer with injector cleaner, pump it up until I have a little bit of pressure on it, and then hit the switch for about 1-1.5 seconds at a time. You don't want to hold it open too long or you run the risk of burning the injector out. This will clean your injectors up nicely, and then just reseal them with a Rennbay kit, and put them back on the car. Don't forget to lube the seals and pintel caps with a bit of ATF first, before installing them.

For the faint at heart there is always witchhunter.com which a lot of guys on the Porsche forum use.

I heard amsoil is another good choice for injector cleaning.
What ever you choose run the tank real low then put the cleaner in before you fill up.

Geius Maniacal · 05-25-2005, 09:53 AM

when i put the stuff in, do i want to run it for a little while or should i fill up the tank right after?

Geius Maniacal · 05-25-2005, 09:54 AM

by the way, thanks for all the help guys

Gear Dog · 05-25-2005, 11:24 AM

The auto parts store is right down the road from the gas station that I go to.So I pick up the injector cleaner add it to the tank then drive to the gas station. I think the reason for doing that is to get some in the fuel lines before diluting it with more gas. Not real sure on that though.

on the seafoam web site it says that u can use it to clean the engine too. it only shows how to do it for carborated engines. how would i do it on the 22re? just add it with the oil?

burger · 05-25-2005, 05:53 PM

Yeah'a lot of people add it to there oil shortly before they do an oil change,and other people add it to a fresh oil change.

Toysrme · 05-25-2005, 06:00 PM

Add it with fresh oil so it has a chance to actually clean the engine.

Geius Maniacal if you read closer it tells you to use a vacuum line to suck/pour it into the intake tract.

Seafoam is great!

if i wanted to get the "best results" how much should i buy and how often should i use it. it says every 3000-5000 miles, but does anyone know from experience what is the best?

tcr22 · 05-25-2005, 11:18 PM

i take off the pcv line pour it into the pcv line slow

This setup may work for slightly dirty injectors. Ideally the filter should be removed from the inlet end of the injector and then reverse flush the injector. There is usually lots of crud & rust that builds in that area. Your method may break loose some of that stuff and it can get lodged down at the pintle.
Also, high concentrations of cleaners are hard on the internal seals and may cause them to fail sooner.
