4G93 DOHC Problems

[drummydrew]

Adjustable Fuel Pressure Regulator. I read that standard pressure is around 2.7-2.9 bar at idle. Yours is a bit high tho.

its clear now, thank you! my engine was previously running lean so told my mech to keep it at that bar. running rich wouldn't give me problems ya? actually replaced both the fuel and vacuum hose and double checked it, i believe its time for a new regulator :bebored:

really hope that will remove the annoying gurgling noise

Depends from car to car, some set higher, some lower.....

Yeah. I'm still curious about his car 'gurgling' noise tho.. :hmmmm:

 

[drummydrew]

wish i could describe it to you... sounds like the car is breathing with phlegm down its throat, still cannot confirm if its fuel or air intake related yet.

now saving up for a new regulator and stepper motor then will send it in for a more proper checkup. i really hope any of you seniors can hear the sound for real :wavey:

If loud enough can try video it....

i will surely do it when get the chance! then can do web diagnosis already

hello there all sifus, i've only got time to surf back in here for and seems like alot has been going on! i enjoyed reading pages of feedback in the Satria 1.6 thread anyways im back with some update on the "gurgling" noise which was mentioned last time, which is NO update

sent my car to another supposed more trusted mechanic and he told me it has nothing to do with the fuel system so it could very much be a loose nut, he said. putting that aside, here's another recent starting problem which requires me to pack an extra battery in the trunk for emergency jump start - i have a fairly new battery considered its installed earlier this year to begin with, left the car untouched for 2 days, realized battery's dead/alternator lost charge so i jump started it, WORKED, let it run for 15 minutes with AC and lights all on, then realized that there's a power loss problem:

turned it off, then this happened when i tried starting it again:

Bro, your alternator ok condition? Stock grounding worn out? There's one grounding from battery negative to chassis and another from chassis to engine block (default). Perhaps those are worn out.

Yup, first check you alternator charging rate. If alternator problem, then no charge going into the battery.
If alternator ok, then check battery, because maybe battery is dead cannot store incoming charge.

 

[drummydrew]

will get it checked first things first tmr! thanks!

 

[vr2turbo]

Oh! if all okay and battery goes dead after a few days, check for parasitic current draw also

If your battery is not charging, then the battery light indicator should be on at your metre/instrument panel console. At least that is how i noticed that my alternator is dead few weeks ago. The light just doesn't go off even after i changed into a new battery.

Problem is sometimes it does not light up. Of course normally it does if alternator fails.....

I guess bringing it to the mechanic and mention the problem is the best solution then.

Yup, test with meter is the best.....

hello sifus all, i wanna ask if anyone has any idea what is the normal charging rate for 4G93's alternator?

recently fitted a new battery, FPR and stepper motor - the gurgling noise as mentioned before is gone, highly suspected that the old one was faulty causing inconsistent flow hence the noise. However now, a new noise has arose

as shown in video, with both AC on/off.

[vr2turbo]

Sound like the old style dial up modem sound.......hhahahhaha

Jokes aside, sound like scrapping on something, check the bearing also.

Battery charging rate normally 13.6 to 14.4v

Have u checked the pulleys bearings?

Jaring dial-up. Hehehe

that's what i thought when the sound came up! 56K modem from the past dialing up in my car lol!

which bearing exactly should i look into? AC compressor/cam/crank pulley?

All. Does it gets louder when you drive or just when idling? Mine had that before. Just weird noise when idle due to the tensioner pulley bearing worn out.
