Toyota Innova Gas Tank woes

Innova '07, Gas.

Butas na. nung isang araw, gas was dripping.

Twice a week lang kung magamit ang innova kaya umabot ng 63k bago lumabas ito.
Symptoms, so a few months ago, everytime I start driving, after around 5 minutes, you would hear a faint 'lagutok' sound. I thought there was something loose, pero laging once lang, at kung first 5 minutes. So now, that explains the sound, the negative pressure warps the whole tank and the 'lagutok' is the tank warping.

So I had this problem around friday kasi amoy gas daw sa paligid, when I looked below, I saw signes na parang may dried salts trail. So ok, i thought pinhole leak. But Friday, I had to fetch someone from the airport. Passed by Rapide, pasara na sila. so no use. That was really stressful since gas was draining fast, and Fort to Airport traffic is... ^&%$##$^&*.

Saturday, no leak. used it manila to cubao and back.
Sunday, no leak, pero parang biglang nabawasan gas.

So Monday, I was planning to go to servitek before noon, my brother gave me a call that the leak was really strong. So i opened the cap, then walked to ACE hardware to get epoxy putty (buti malapit SM)
1. for water, can be stuck to anything even when whet
2. epoxy putty steel filled

then went to the nearest servitek. I had it lifted, and ayun nga, it is leaking just beside the metal strap. exactly as in the picture shown in an earlier post. so we tried to put the 'water' putty, made it stick. then after, i put the steel filled putty over it. so sabi ko temporary lang ito until I can get a new tank.
Monday whole day, it seemed to work kasi walang leak.
Then Tuesday, leaked again while parked. So I opened the cap, kasi I thought it was the expanding gases inside the tank that pushes the gasoline out of any pinholes. Also, finally decided to get a new tank, Called Aerodynamic, 2 months pa raw ang tank. out of stock sa planta. So next option is 'surplusan' as bulacan.

Wednesday, lo and behold, I saw this thread because of 'is it ok to keep gasoline tank uncapped'. So tank is still not tightly capped until now.
Am on page 30 already of the thread. just compiled all I read.

Pag nasa US siguro tayo, bilis makahanap ng lawyer na magrerepresent sa atin to file a lawsuit.

Kung insured pa sasakyan mo, you can claim that sa insurance. Pwede ka magclaim na nasabitan or what, kasi di naman accepted ng Toyota na at fault sila dyan.

Mukhang 2007 below ata ang nadale ng sakit na ito.

Ano ba yung filling habit mo ng Innova?

Para mabawasan ang negative pressure everytime na uuwi ako, buksan ko sandali ang gas cap para ma release ang pressure. Twing bukas ko nga. Parang sliding door ng startrek ang tunog, swoosh!

just cleaned the tank cap now.
analyzing the cap function, mabilis lang makakapasok ang hangin to relieve the negative pressure kung di barado ang cap. and yes, the filter of my cap is full of soot.
upon testing, it needs more pressure to move the valve on the cap when letting expanding gases out than when letting air in.
maganda siguro matest mo shibby if you still get that swoosh after you clean the filter on the cap. medyo mahirap alisin yung white plastic from the black housing, you have to align the notches. pag naihiwalay mo na sila, that's when you find the filter.

Change your charcoal canister bro.

ito din ginagawa ko sa innova namin lately. 2005 model sa amin pero so far ok pa naman.

tama lang naman na may pressure lalabas every time i open the gas cap after use right?

The easiest and quick solution was have your mechanic pull down the tank and bring it to radiator repairman near your area. Radiator repairman can patch over metal sheet on top of the torn portion. Epoxy is only a stop gap solution and usually will wear out in 5-7 days.

If your Toyota Innova is already out of warranty.

1. Fix the gas tank via radiator repairman.
2. Replace Filler Cap
3. Replace Charcoal Canister

Try looking for jb-weld cold weld upoxy, very strong and is very resistant to gasoline. I am using this on the tank of my vintage bikes. I even used this on crack manifolds..

Will be having the tank replaced. Owner wants the tank replaced instead, mas mabilis din na trabaho siguro.
to Kristine, paano mo nabuksan yung filler cap at nabawasan ang spring? nung sinubukan ko sa akin kasi, parang nakadikit talaga yung parts nung cap. was able to separate the black housing from the white part lang.

Anyway, the cap was also designed to let the tank breathe. it lets air in, and lets expanding gases out.

medyo masakit talaga yung gastos sa tank ano, pag naalis ito, ipaaayos ko na lang, tapos tingnan na lang natin kung may ibang papasahan. para at least, replacement lang ng part agad.

So you guys were saying not to have the tank filled up full? why? or full tank na hanggang automatic lang?
