and still do the italian tune-up. it clears carbon deposits marvelously. full throttle, steepest fastest longest uphill you can find. several times. hondas love that. i did some head work on my civic a couple of years ago. i'd been flogging the poor thing to los angeles and las vegas from san francisco at high speed for a year. it was so clean inside, you could see the metal of the piston tops! |
The main reason I want to get rid off the carbon build-up is the pinging in
the pistons when the engine runs hot and hard. What you are suggesting would
make the pinging probably intolerable during the "Italian tune-up".
Besides, wouldn't that also damage the catalytic converter (CC)? How about
any dark exhaust coming out of the muffler during the process? That might
almost invite the cops to pull me over, no? Back in '80s I once tried one
of those cleaning additives by pouring it in a 4-barrel carburator and boy,
what a smoke that created for a while behind my Cutlass! (That was before
CC.) I would not want to go through that experience again.
By the way, I usually fill up with Chevron gas that does contain the Techron
additive but I don't see any noticeable reduction in pinging. So what gives?

In the old days of carbureted vehicles, you could use water injection
which literally "steam cleans" the combustion chamber. I have no idea
whether you could do so in a modern fuel injected computerized engine
though.

if you're getting detonation, for a honda, the most likely cause is excessive carbon build-up, the plugs are the wrong grade, or the timing is out. it could be an excessively skimmed head if the head's been off, but that's not so likely. |
expected after that much use, even with Chevron gas and proper tune-up.

check timing, [with the timing reset jumper in place], make sure the plugs are good, i.e. just change them anyway, use ngk or denso, then do the italian thing. don't worry about the catalyst - it's made to withstand that kind of treatment. |

various additives but I don't know if one could trust their claims. None approved by AAA ? Is Redex 1 of these ? |
