Ticking from engine, possible fix.

yearight · 03-11-2007, 04:04 PM

I have the ticking in my engine just like everyone else. Fuel injectors. I think it is what I read it is.

Anyway I think I am part way to a fix. I needed gas last night. I noticed when I got out of my car the ticking from the engine was very loud. I left my car running and once I opened the gas cap the ticking stopped immediately.

Could there be not enough ventilation from the gas tank that would cause a vacuum and affect the fuel injectors, thus causing the ticking?

Just thinking out loud.

im sure honda would have noticed if there were a problem.

but all i can say is i know you shouldnt leave your car running while filling up. and two that you shouldnt leave your gas cap off

running your car while your adding gas is almost as bad as someone smoking while doing it.

SIcBoy · 03-11-2007, 05:24 PM

electric in the air

static electricity

Ok, anyway! You don't actually think the car will blow up do you? Your car is an internal combustion engine. The engine running will not ignite you filling up the gas. You however could go back into your car, create enough static energy and create a spark when you go to hang up the fuel nozzle, thus creating a fire of the fumes.

Fire needs 3 things, (Heat, Fuel and oxygen) A gas tank will not just blow up, because there is not enough oxygen inside the tank for combustion to happen. The fumes on the outside may ignite if there was a source, but then again there could be too much oxygen and not enough fuel. Does it happen? Yes. Does the engine running cause it. NO!

Back to the subject, was it just chance that the ticking stoped when I opened the gas cap?

Static electricity + Gas + You touching the wrong thing= BOOM!!!!!!!!

SIcBoy · 03-11-2007, 05:28 PM

it happens in the movies

i guess its a safety precaution

you havent seen the vids with the people just pumping gas and all of a sudden a flame ignites. static electricity has a lot to do with it.

Exactly! You do not get static electricity from your car running. They get the static electricity from getting out of there car or going back in while pumping to get their cash, wallet or purse then back to hang up nozzle and kaboom.

I always make sure I ground myself on something metal before I go to pump my gas. ALWAYS! The side of the car, the side of the pump housing.

Take natural gas for instance. When the vapor mixes with air, it is only flammable when the mixture is between 5-15 percent natural gas. When the mixture is less than 5 percent natural gas it doesn't burn (not enough fuel). When the mixture is more than 15 percent natural gas in air, there is not enough oxygen for it to burn.

It is called a google search.

And talking on a cell phone will probabbly not cause and explosion. Gasoline is 4 to 5 times heavier than air (again google search) so unless you are sitting on the ground under you pump than yes it could cause a spark and ignite.

Look just educate your self, don't beleive everything you see on TV or read on a forum.:)

Cell phones do however cause brain cancer.

SIcBoy · 03-11-2007, 06:18 PM

back to the subject....
what is causing the ticking?

SiCali · 03-11-2007, 06:19 PM

wow a bit sensitive aren't we? it's just a precaution. freak accidents could happen. *shrugs*

as for your original post, i'm not exactly sure what ticking you're referring to. when the engine is off, there is a "ticking" noise that does occur. from what i've been told, this could be the result of the exhaust pipe cooling and contracting. i personally don't hear any "ticking" while the engine is running. could you elaborate on the sound a bit? other than that, it could be a vaccuum issue when you opened up the gas cap.
