So I bought an 82 300SD that has a Lovecraft conversion ...yeah, I know

Anyway, I know the former owners, they bought the car without the conversion, had it put in, then hardly used it. When they did run WVO, they were meticulous about settling and filtering, so I'm not really worried about major damage. Also, it has the Davco 234+ filter which you can get good filter elements for, so I don't think I'll bother to remove the system - at this point, it just preheats my diesel.

Anyway, what I'm wondering about, is the quickest easiest way to set up a temporary water injection system to clean out the carbon from running cold veggie. I'm planning on a nozzle change sometime next spring, but I'd like to remove any buildup first. Not looking for horsepower, just a good steam cleaning...

I have searched a bit, but I keep getting distracted by talk of vnt's and oversized ip elements. I need to get it mechanically sound first!
