Question I officially have no memory! Does water kill O2 sensors??

I've been out of the automotive world for one week and already I can't remember if injesting water kills O2 sensors. WTH is wrong with me?? (Don;t answer that! )

Anyway, a couple weeks ago I posted another thread about injesting a serious amount of water and I am now getting some weird hesitation problems (intermitent) but it could just be in my mind.

So, to make a long story short, does water kill an O2 sensor? Thanks

Eric

H20 is a by-product of combustion. Water is already and always in the exhaust.

nope, but coolant does, so does any kind of solvent that ends up in the air vent holes.

p.s.: there's a list of things wrong with you

Water might hurt it if it was hot, then the tail pipe was flooded with water. Rapid contraction can hurt alot of things. Bearings have a problem with heat and water as well, but it is not directly related to the bearings themselves.

I don't think that you submerged your exhaust, if I remember correctly anyway....

cheeRS,

That's what I thought but I wanted to make sure a large amount of water won't harm it.

What kind of hesitation problems do you have? If its a suttle hesitation you can try a single piont ground set-up. Ive read that that helps some hesitation probelms. Or if your hesitation problem is like mine, really bad so you didn't accelerate, It won't help. Im still tring to figure out how to fix it.

I reset the ECU and it pretty much took care of the problem. Thanks

your's is prolly a dead cylinder, most likely a blown head gasket...phase 1 blocks seem to be famous for the head gasket issue.

eric-is it as you come on boost?? have you looked at the MAP values??

Map values are fine. Zenier diode is still working. Like my previous post says (read it you little bitch ) , I reset the ECU and it fixed everything. Car runs better than ever now! I think all the water I took in freaked the computer out and all it needed was a reset.

yeah... chrome plated muffler baring seem to work the best, especially considering their robust character...

anyway, on the original topic, let me run with this, and then please correct me if im wrong...

Combustion of fuel (primarily octane)

C8H18 + 12.5O2 ---> 8CO2 + 9H2O

therefore, water is a biproduct of combustion, as previously stated. Now, based solely on Lachattlier's (spelling?) principle, adding water to the intake gas mixture will inhibit this reaction, and ultimately limit power. Right? So it is likely that the best air is dry air for maximizing your power.

This said, why do some people use a water spray setup?! Obviously, there are more factors than general level chemistry dictating the efficiencly of this whole process. Can someone shed some light please?

Water spray is not for power, it's for protection. It deters detonation

Are you considering water injection into your exhaust manifold? I heard that's a good way to bring your exhaust temperatures down. J/K

Bearings, when hot, then quickly cooled in water will contract. I don't know exactly what happens, weather that squeezes out grease or what, but water will get into the bearings. Of course bearings with water in them instead of grease have lots of suck.

THis is a problem with boat trailers that have been towed for a few hours and have become hot, and people with little patients back their boat into the water right when they get where they were going. Then on the way home (maybe after a few trips) they have a bearing failure. This is the reason for the majority of vehicles on the side of the road with a boat attatched to them, or boats left unatteneded on the side of the road. Of course flats as well, most people don't have a spare for their trailers. ***

cheeRS,

Greg
