Gas Engine with Diesel sound!?

**arnielbenz** · February 13th, 2009 09:17 PM

I have a problem with the other car...

96 Ford fiesta 1.3 EFI, 68000km milage. Gamit lang in short distances 3X a week. Maingay ang makina running or idling no difference, sounds like passenger jeep. New wire and spark plugs(pinalitan 1 month pa lang), with regular change oil, air filter, never nag overheat. Nag start lang last December 2008 kaya pinalitan wires and plugs pero ganon pa din, at hindi naman mataas ang menor dahil check ng mekaniko at ramdam ko naman kung mataas menor. Okay pa naman tumakbo malakas pa humatak at matipid pa sa gas, I tried many times patakbuhin ng 135kph. Sabi mekaniko normal lang daw ung ingay kasi luma na car-huh!

.

May isa pa ako napansin may crack yung engine, so tumatagas ung coolant sa mismong engine(sa may tapat ng oil filler cap). Hindi naman malakas ang tagas kasi hindi nga halos nakakabawas ng coolant sa reservoir. Pero it's not related doon sa ingay ng Engine kasi last monday lang nangyari ung crack.

TIA mga sirs!

Sir ang tunog ay parang maliliit na bato sa loob ng engine.

Need more info on the characteristics of the sound. Does it change as you increase RPM? (ie. it disappears/gets louder/increases in pitch, etc.) The more specifics we have, the better we can help you.

About the coolant leak, unless you can really see the crack on the block itself, it may also be caused by a blown head gasket.

Sir it does not change the sound, as i mentioned no difference running or idling.

And the leak is in the block itself, not on the head gasket.

Thanks a lot sir

then kung sa block nga yan , possible engine na ang sira.

That crack worries me. The noise and the crack may be related. It's hard to be certain without actually looking at the engine.

Other noise sources off the top of my head that may match your description would be:

1. Loose timing belt or drive belt, flapping/vibrating
2. Related to #1, the tiiming cams may be altogether off. This can happen if the timing belt jumped a tooth. This may cause extensive damage, may be the reason for the crack
3. An exhaust leak

probably just noisy tappets, shims or lifters.

sir oj88, aga cruz, bambino and speedyfix,

thanks a lot, anyway now lang ulit ako nakpag reply because im too busy. Wala na yung car ko, binigay ko nalang sa relatives ko, kasi check nga mekaniko talaga may sira na yung engine block. Pero hindi naman daw gaano problem yun kasi maliit lang naman. At yung sound hindi ko na pinaayos. Ayun pinag tiyagaan nila. thanks a lot again mga sir.
