Need Advise....MAZDA 3 hardstart then TOK TOK TOK Engine Sound

[ch0k0y]

Hello TSikoteers,

Need inputs po for possible trouble ng Mazda 3 ko.

Almost 1 month na di ko siya nagamit tapos kahapon drive ko siya ng aroung 10 kilometers with no sign of any problem.

Attend sana kami ng church sana kagabi eh hard start na siya kaya di ko na ginamit. This morning check ko ulit - check battery (OK naman). Start ko ulit siya talagang pilit then nagstart pero iba yung tunug ..... parang tok tok tok sound ng engine... di ko na tinuloy.

pwede ba pa chek sa mga mechanics jan sa mga talyer o kelangan talaga itawag pa sa CASA? ANo kaya possible na sira?

17Kkms pa lang, last maintenance niya is 15kms december 2008pa.

Car is 2006 Mazda 3.

Looking forward po sa mga inputs nyo.

Salamat.

if its still within Warranty. better bring it to CASA. actually have no idea what could be causing the tok tok sound. can u find out more by listening to it and describe to us once again where its originating fm.?

unfortunately last month expiration ng warranty niya.
Yung tok tok tok sound ay yun na mismo ang sound nung engine.

sir if i were you, mas mabuting sa CASA mo na lang dalhin even out of warranty.. Slightly expensive nga ung mga parts nila doon pero tiwala ka sa kanila kasi lahat my warranty doon, at siguradong alam nila ang gagawin dyan sa unit nyo.. sa mga talyer kasi sasabihn ito may problema, ayun may problema.... haggang lahat na lang e sabihing may problema syempre mapapamahal ka din sa gastos... RIGHT?... and sometimes sa talyer kasi kinakahoy ung mga original spare parts or plugs ng auto...

May be some water settled in your fuel tank... what is the current fuel level?

[ch0k0y]

Fuel level indicator is 1/4.
OKey lang ba piliting start ?

thanks for the reply.

Not unless you're sure about what's causing the sound.

If it's "knocking" or something similar, running it could be potential disastrous for the engine. If it's something like a loose fan belt or engine mount, then not so... not hearing the sound myself, I can't say what it might be.

1/4th tank might be low enough to allow condensation of water inside... but it'd have to be pretty bad gas to begin with... personally, I'd call a mechanic for a home consult, or tow it to the dealership or a good garage instead of running it that way.

Have you opened your hood? check for unusual stuffs like dead animals etc.

[ch0k0y]

Niky; not really sure if this is a "knocking" sound.
HorsePower; Yes, Sir! Opened up the hood and check for any unusaul stuffs but nothing is abnormal.

Anyway, here's the latest update. I left again the car in the garage and for usual activity of my wife is to start it every wednesday. She said she started it successfully in one attemp but she noticed that it's bit unusual white smoke from the tail pipe but went normal after a while. THis morning, it started as normal as before, one click and no smoke.

Could this be the first speculation of Niky; about condensed water inside the fuel tank?
