Cleaning Your Injectors?

How hard is to to remove and clean my injectors? I'm running on WVO and I'm interested to see if I'm getting any coking on the injectors, just wondering if this is something I can do on my own, or if I need to seek professional help (let the insults begin :-) )

Adam I'll like if we could be down the for the 19th in Nanaimo. Our plans to go to Denman and Island Restores were blown for this week/weekend. Missing out on the Hornby/Manitoba Delica install.

Do you add anything to your processed veggie? I added like 1 to 1/2 liters of acetone for the first two years to a barrel, and maybe an ounce to a full tank of diesel. Last spring my mechanic had Randi's injectors off and said they looked perfect. BUT, over 6 plus times this winter someone left her van on veggie overnight, and that 10 minutes to purge and start likely builds deposits on injectors equal to 20000km's. And I haven't added acetone for a year plus, it was only available in town in 500ml containers. Now her Delica has the occasional puff of black smoke. I want them cleaned also, like to try that sonic method CVI does. Rarely Cambodian tire has 1l bottles, so I just stick to diesel conditioner. Good experiment is try different solvents on something that burns WVO often deposits, I used my little metal camp stove harden soot; acetone was even better then xylene.

Removing the injectors look easy but we used a mechanic; didn't have the right deep metric socket.

I guess I best know what I'm talking about then :shock:

I haven't been adding anything to me WVO. I was adding a bit of biocide on Noel's advice, but I'm a bit concerns about the enviro implications and I'm not sure how much of a problem a biological infection is after reading a bit more.

Acetone looks like a good idea, I'll give it a shot, thanks.

Injectors are stupidly simple to disassemble. There is even a diagram on the wiki in one of the manuals in case you dont remember how to put it together. The only thing I would do though is get the seal that goes between the head and the injector. Did my buddies Pajero and the stupid things would not stop leaking there (ok it was leaking there in the first place but still, not a bad idea to change).

This is what I wanted to hear, thanks Eric. Had they just been pretty simple, I would have had second thoughts, but stupidly simple is right at my skill level. Can you get the seals at Lordco?

I do not believe so (we tried). My buddy ended up just dumping it at CVI because he wanted to get the injectors all setup properly and I didnt have the time or inclination to make a tester. Keep in mind his were leaking past for a while. There was a thick buildup of junk so bad that you couldnt even find the hex part of the injector. I would bet if yours arent leaking now, they would probably be ok to reuse.

I've often wondered if perhaps those Ultrasonic Jewelry cleaners may not to the job?

The one pictured above for example costs about $45.00 http://www.sterlingtime.com/uljeclcdcdpr.html

Cool idea, may clean the outside but not sure if it will clean inside the nozzle/spray pattern. Still like the idea though! Someone's wife must have one of those... Just don't let her know why it went missing!

I have access to a heated ultrasonic cleaner if anyone in calgary is doing theirs.
