SAI Flush
Posted before but got little response (two replies I think) .....unusual for this board....so am trying again.
I have had my car for nearly two years, average oil consumption is about 1 qt to 1500-2000 miles depending on use and ambient conditions.....leak down test is very good. But I have SAI clog and will need to sort before spring when it goes for its MD smog inspection......so I intend to take my car off the road for a few days over Christmas and do a "flush".......Kelly Kim was kind enough to send me his DIY kit so with that and a rented compressor I will hopefully cure the problem once and for all.......
QUESTION: What fluid have you guys used succesfully to perform this flush.....

A more aggrressive maneuver (which I've done myself) is to, using a plastic straw -- one end dipped into the can-of-whatever and the other end fitted to an intake manifold inlet, (is to) let the engine 'suck' in the cleaning-fluid "directly" (into the cylinders). Be prepared for LOTS of smoke out the exhaust and some severe "coughing" of your engine, even some misfiring too. But, by God, does it run smooth 'afterwards'.
An additional 'trick' is to let the engine suck in so much fluid (without letting it hydrolock!) so that it stalls. Then leave the engine off overnight to let the fluid REALLY do its job. Then start it (watch out for smoke!).
BTW, many do NOT endorse this method as they fear any carbon that's 'dislodged' or turned into goop, by the cleaning fluid, will clog up the cats. Sooooooooooooo --- I'm just offering this 'advice' as 'something you could try' (and it's a CHEAP 'try' too!!!) - before going down the 'put-the-mechanics-kids-thru'-college' routine.

I've used some very stinky Pennzoil stuff which was OK, but am planning to use some new carbon remover used for aircraft, called X-IT. It's not available at your local store, made by Pantheon Chemical. Some of the benefits I see are that it's water-based, non-flammable, effective enough to be used on aircraft without destroying anything

When do you intend to use ...
So, my current plan is to do it either in the next month or so (but I'm in Toronto and it's already getting too cold - it is water-based after all), or in the spring (I'm waiting right now to receive my 4-post lift so that's the priority). Sorry I don't have more info for you - but I researched this quite a bit and had a hard time accepting all of the solvents that were put out there. I used the Pennzoil stuff (I'm assuming it's similar to Techron - I can't get Techron up here) and it's just terrible to work with - and it was such a pain that I really didn't want to do the SAI flush again. The smell, flammability, etc. etc. - I went looking for an alternative

Love the smoke show tho'

I let the dealer do it. They normally charge 9 hours (@ $94/hr) for the job. I only had to pay for 6 hours as I was having a 90K service done. It worked except for #4 cylinder which only partially opened up.
