    sir...
    tanong ko lang sana kung ok pa yung engine ng Hi-ace(japanese 2nd hand 1KZ-TE engine)) ko...

    ang nangyari kasi pauwe kame kahapon galing sa Ilocos going to manila may nadaan ako na malaking bato hindi ko alam kung sinong hudas ang naglagay nun doon...ang nangyari ay tinamaan yung water line papunta ng heater...ngayong tumutulo yung tubig(itibabi ko agad para makita kung anuman ang naging problem ng sasakyan) kaya ang ginawa ko ay sinarado ko yung line tapos nagdagdag ako ng tubig sa radiator(about 4liters) then takbo ako from la union onwards(going home) about 30 mins tapos huminto ako sa may gasoline station...

    check ko yung tubig at pagbukas ko nun radiator cap ay bumulwak yung tubig(sa init siguro ng makina pero nakikita ko yung temp guage ko nasa normal pa rin)...nabahala ako kasi alam ko na hindi normal yung ganun kaya nagtanong ako ng mekaniko sa gasoline station...

    ang ginawa ng mekaniko ay nilagyan ng hose na pangtubig muna yung broken line para mag-circulate ulet yung water, temporary yung ginawa niya...tinanong ko siya kung may damage kaya sa engine ang sabi niya ay may konting damage na raw sa cylinder head gasket kasi raw nag-overheat...

    1) ngayon...totoo kaya na may tama na yung cylinder head gasket ng engine ko?
    2) nakita ko na may tama yung lower suspension at yung kinakabitan ng caster arm at sabi ng mekaniko ay kailangan na raw palitan yung lower susupension...totoo ba ito???

    pasensya na po kayo sa mahaba kong inquiry huh...maraming salamat po sana ay matulungan nyo ako...

    sir...
    tanong ko lang sana kung ok pa yung engine ng Hi-ace(japanese 2nd hand 1KZ-TE engine)) ko...

    ...ang nangyari ay tinamaan yung water line papunta ng heater... tumulo yung tubig,....kaya ang ginawa ko ay nagdagdag ako ng tibig,...then takbo ako from la union onwards.... about 30 mins tapos huminto ako sa may gasoline station...

    check ko yung tubig at pagbukas ko nun radiator cap ay bumulwak yung tubig (sa init siguro ng makina pero nakikita ko yung temp guage ko nasa normal pa rin)... nabahala ako kasi alam ko na hindi normal yung ganun kaya nagtanong ako ng mekaniko sa gasoline station... Talagang nag overheat ka. Pero normal yung temp indication dahil mababa na ang coolant level mo. Hindi nakita ng temp sensor ang true temperature dahil hindi na ito nakatutok sa coolant. Steam nalang ang nakita nya. Hindi magandang temperature conductor ang steam.

    ang ginawa ng mekaniko ay nilagyan ng hose na pangtubig muna yung broken line para mag-circulate ulet yung water, temporary yung ginawa niya...tinanong ko siya kung may damage kaya sa engine ang sabi niya ay may konting damage na raw sa cylinder head gasket kasi raw nag-overheat... Pwedeng meron damage, or pwede rin wala. Depende ito kung gaano kataas inabot ang temp, at kung gaano katagal. Masama kung tumigil ang makina nang sarili, na hindi mo pa ito pinapatay sa susian. Kung ganito ang nangyari, sobra na ang thermal expansion ng pistons at sumikip na sila sa liners. Kumayod na ang pistons sa liners. Hindi sana.

    1) ngayon...totoo kaya na may tama na yung cylinder head gasket ng engine ko? Malalaman mo yan kung bumubulwak ang coolant. Mag lea-leak ang compression gasses papunta sa cooling system. Dadaan ito sa damaged cylinder head gasket.....
    2) nakita ko na may tama yung lower suspension at yung kinakabitan ng caster arm at sabi ng mekaniko ay kailangan na raw palitan yung lower susupension...totoo ba ito??? Madali malaman ito, silipin mo nang mabuti ang pangilalim...

    pasensya na po kayo sa mahaba kong inquiry huh...maraming salamat po sana ay matulungan nyo ako... YOU ARE WELCOME....HAPPY EASTER, GODBLESS

Steam nalang ang nakita nya. Hindi magandang temperature conductor ang steam. (sir,,,about doon sa mababa yung coolant level parang hindi naman kasi nilagyan ko naman ulet ng tubig at pinuno yung radiator...)

Dadaan ito sa damaged cylinder head gasket.....(paano ko ba matetesting kung nasira nga talaga yung cylinder head gasket??? kasi kanina tinidnan ko ulet pag nakaminor wala namang motion yung tubig sa may radiator cap,,,pag nirev ko ayun gumagalaw,,,normal lang ba yung ganun pag nirev mo kasi diba aandar yung water pump nun???)
    2) nakita ko na may tama yung lower suspension at yung kinakabitan ng caster arm at sabi ng mekaniko ay kailangan na raw palitan yung lower susupension...totoo ba ito??? Madali malaman ito, silipin mo nang mabuti ang pangilalim... (ayun pinacheck up ko nga sa gumagawa ng suspension may tama nga at kailangan palitan yung lower suspension tapos yung cross member na nakawelding sa body ay kailangan daw painitan at idederetso at papalitan yung lower suspension...totoo ba talaga ito???)

    pasensya na po kayo sa mahaba kong inquiry huh...maraming salamat po sana ay matulungan nyo ako... YOU ARE WELCOME....HAPPY EASTER, GODBLESS

    Pwede. Plug up mo yung supply and return hoses.

    mga boss at sir,

    i need your help. i'm now in a situation wherein nakababa na yung old crack cylinder head nung sasakyan at nakabili na ako ng new replacement cylinder head. the problem is, yung mekaniko na originally gumagawa nung sasakyan di na sumulpot. i've tried calling and texting him but haven't got any reply.

    can you please recommend a good and honest toyota revo diesel engine mechanic that has tools and willing to go at my place and can install the new cylinder head.

    my exact address is e. rodriguez st. malibay, pasay city. (in between philtranco and evangelista, just few meters away lang po sa edsa)

    exact make of the car: 2004 toyota revo sport runner (diesel)

    thanks in advance!

    sir dieseldude, could you share your knowledge about commonrail fuel injection, I just installed a plug and play gizmo that connects to the fuel rail sensor. and this gizmo is supposed to extract more power from the engine. it claims that it will not increase the pressure but just add more fuel.

    My question is do you see any problems that could arise from my modification. One thing I observed that im very happy with is after I installed the gizmo is its less noisy than before. its for a mitsubishi 4m41 commonrail engine,

Since your gizmo is wired to the rail pressure sensor, it probably alters the pressure signal to the ECU, fooling the ECU that rail prssure is lower than required. The ECU compensates either by increasing fuel pressure or by increasing injector metering time.

    My question is do you see any problems that could arise from my modification. Yes, more fuel = more power, but with higher combustion pressures and heat. Another thing, your vehicle warranty may be void if Mitubishi sees this.

    One thing I observed that im very happy with is after I installed the gizmo is its less noisy than before. its for a mitsubishi 4m41 commonrail engine, I'm glad you're happy with this device.

    You're welcome.


    Fyi, this gizmo may not cause any significant harm to your engine. Automotive applications engines mostly operate at idle or part throttle while cruising. It is rare that the accelerator pedal is floored for extended durations. Your gizmo functions very briefly during acceleration, and this is a nice feeling... good engine response. Gizmo can however operate continuously when car is fully loaded during long uphill climbs.

    I have a Nissan Terrano TD27 Turbo

    Medyo hina hatak and mausok

    I went to a calibration center

    Calibrated then linis yung Nozzles - Tangal usok

    Pero humina hatak, todo na apak sa pedal pero hangang 75-80 nlng spped unlike before napaptakbo ko ng 130 km/h sa hiway

    Adjust adjust, then may pagkakataon naman na parang pigil makina

    Ngayon medyo ok naman ung takbo after ilan days ng adjustment at pabalik balik

    Problem ko naman ngayon may naririnig akon tok pg apak ko sa pedal and when it reaches the 2.5K rpm mark, may tok so di ko na pinapaabot ng 2.5 rpm pataas.. Dati naman wala to

    Could it be the calibration? The timing in the calibration?

    Please help

    Ayaw ko na kasi ibalik doon e, almost one wekk na ko pabalik balik. Hanap na lng ako ibang gagawa pero please i need your opinion first.

    Ayaw ko naman kasi tangapin na kumatok na bigla makina ng Terrano ko, dati naman hindi ganito, nung nagpacalibrate ako, may tunog na


    Please help kung ano dapat gawin and Thanks
