Can't really offer follow-up on the cc treatment, as I did it only those few times. That the result was so great, in retrospect, should have made me nervous. I've stuck with the water trick since then, and haven't yet noticed anything that would make me not want to continue using it...

 

im probably going to get flamed for bringing up an old post- but ive always been a fan of these engine cleaning threads.

so far, the consensus seems to be that seafoam is better than water, atf, etc.


well, ladies and gents, i have something that is MUCH better than any above.


IF you have a jonhson/evinrude outboard motors dealer in your town, do yourself a favour and buy a can, or a CASE of "engine tuner"

my shop uses this exclusively to clean carbs, etc- its non corrosive, doesnt hurt seals, but somehow, it cleans ALL junk out of the carb- and itll even take carb jets and remove the tarnish from them and make them look new....some how..


we did a cleaning solution test between carb cleaner, BRP (johnson/evinrude) engine tuner, seafoam, ATF, and solvent, and the BRP engine tuner came out on top.


ironic that the directions say to spray it into the engine, like seafoam, but we use it like carb cleaner. the product foams ALOT and sticks very well. the next RX7 i buy, i am going to use a can of this 'engine tuner'.

i suspect after running 1 can through the engine, that the rotors might actually be CLEAN, like......professionally, mechanically cleaned clean. this stuff just works that well....

..thought id share..

 

so what is it called exactly? Engine Tuner?

 

hmmm . . . . i dont know . . . lolz . . . lets try it and change oil after . . . need a rebuild anyway . . . lolz

 

only issue I could view is the vac line breaking down...

 

i may have to look into trying this...

 

I am oing to try it tomorrow

 

(going) sorry

 

ATF is fine for building compression.

It's for the parts of automatic transmissions, leaving oil in our engines is great for the seals and brings the engines back to life.

I've done the water treatment on a few rx7s and the results were great, a 79SA went from not revving past 5k or so and after it'd rev much higher, idle smoother and didn't smell as nasty (exhaust) my FC seemed to also enjoy the treatment revving smoother

 

Johnson Engine Tuner.

need to get it from a marine supply place, or somwhere that sells bombardier, jonhson/evinrude stuff.

 

tell me more about this engine tuner... simple as spraying it into a vacuum line with the engine running? the entire can?

can it really be that simple?

 

By doing the H2O trick-was there any need to change the oil? (for me, regardless of what is happening, I always change the oil after one of these treatments). I read earlier on that some people used a 1 gallon jug of water, put both vacuum plugs from the oil jets (the plugs right under the secondary fuel rail) or used one hose that connected all 4 hoses (the 4 to 1 plastic looking piece), have a second "wheel man" control the throttle and let the engine suck (vacuum) the water until the entire amount of water is gone...In my case (I'll be doing the water treatment) but there is a problem, all that carbon being loosened has to go somewhere (out the exhaust); Will this cause damage to my Garrett T-61 turbo? if so couldn't I just take off the turbo manifold and then run the treatment?

 

its the same idea as sea-foam, but its in an aerosol can.





.....and it works like 432X better.. seriously. we use it to clean carbs and make them look brand new. it's seal friendly, but it managed to take off any sort of grime or gum, as well as metal tarnish on brass/copper jets, etc.

 

There was, one time. I chose to let the engine drink as much water as it could, as fast as it could without stalling. It turned the oil into the milkshake. The key to a successful water trick is patience. It can take ten minutes or more, depending on how much water you have, standing or crouching beside the hot engine with the fan blasting you the whole while. It's not at all comfortable, but it's the only way to get it done.


I can't answer turbo questions. I first learned of the trick from Rotary Resurrection (who learned of it from someone else.) If there is a concern about the trick and turbos, I haven't seen it yet. You might drop him a line to follow up the question, tho.

So are there anymore negative results from these treatments?
