Re: Lean Fuel Mixture: the Silent Killer
bondo... nope...
may or maynot be totally clean.. it all depends on the amount of water and the amount of time it's been running.
When 7 out of the 8 cylinders are all pretty much the same as far as carbon buildup goes you have to ask yourself "why is the 8th cyl CLEANER than the rest???"
And it's not running lean....
1.running lean will still add carbon... just not as much.
2. running a bit leaner will increase the combustion chamber temps... but that doesn't clean anything... it's an engine, not a self cleaning oven.
3. running even a bit leaner and you'll be burning a hole in the top of the piston, but not the top of the cylinder head....
4. hopefully you'll never get to 3, and move strait to 4 when your running too lean to a point that your preigniting and the engine running is all over the place or lean popping back through the intake.... in which case anybody would not run their motor.
detonation can be caused by preignition (they are NOT the same thing) but detonation can also occur for a dozen other reasons.
Injecting tiny amounts of water into a running engine can actually increase it's performance (as water artificially increases the octane of the fuel its running, and cools the combustion chamber)... injecting (or injesting) to much water, however, can and will strip the oil from cylinder walls, temper components etc....
answer on the other engine to follow soon!!! care to give it a shot bondo???
