Top Overhaul or Full Overhaul

[1D4LV]

question lang. sa utol ko ito (hindi ito sa akin....)
car is Mazda Familia 96 GLXi.

the car kasi excessively emits black smoke. Tapos parang wala na syang power in acceleration. In fact, parang namamatay yung engine at 2nd gear pag umaahon sa humps.

i am not knowledgable in engines (suspension is my forte...hehehe).
ano ba kailangan dito? top overhaul lang o total overhaul? i've texted Manny (of Cruven) yesterday to inquire about top overhaul. Nasa 5k lang ang expense and one day to complete. Pag total overhaul ba magkano? Tsaka gano kahabang babanatan?

would it be worth it yung total overhaul? or an engine swap will be more cost effective?

sa pagkaka-describe mo sa kotse mukhang total overhaul na yan.

pero kung kulang sa budget, "dukot" na lang. basta mapalitan ang piston ring.

yun din yung una kong inisip, pero ano naman magiging effect nun? tatagal ba yung ganun?

antay natin comment ni speedyfix. as much as possible, gusto ni utol eh yung best bang for the back, be it a dukot, a complete overhaul or engine swap. ibebenta na din nya ata kasi yung oto next year, and knowing yung resale ng mazda, hindi na nya mababawi yung ginastos nya.

Basing on experience bro, mas maigi na total overhaul na nga lang bro. Approximate turn around time nito is around a week to two weeks dahil may mga machining involved. Costs range around P15k (the cheapest) to P25k bro.

Oist Vlad,

Pwede na kitang tawagan this afternoon?

OT: pwede bro, mga 4PM. may meeting lang ako ng 2-4 pm.

[mazingerZ]

okay bro ot na tayo hehehe

Maraming possible causes yung mga sintomas na iprinisinta. kelangan nyan ng mekanikong marunong din sa On Board Computer/Electronic Car Control, tapat, at matyaga.

Kung sa Casa, syempre Computer scan muna para malaman kung sa ignition o sa fueling (sensor side)yung problema, tapos maaring sumunod na yung sa mga compression test atbp for actuator or mechanical problems.

Yung mga veteran mechanics sa casa konteng kwentuhan pa lang, pwede na nilang mahulaan with high accuracy kung ano problema.

Pero minsan, sabi sa kin ng tekno casa, kung dito raw sa pinas, kung due for general overhaul na yung makina ay buti pang straight engine replacement na lang gawin.

Ewan ko lang ha, but pansin ko rin dito sa pinas, pag sinabing na-overhaul na makina ay parang mababa na ang resale value o madalas inaayawan ng mga buyer, unless sinabi mong casa restored o maintained.

Marami kaya talagang mga siraniko dito. Ingat po.

Dukot is BS. If you are going to fix anything, fix it right.

[youngrider]

.......Pero may magagaling din dumukot...Pero pag ganyan kalaki gagastusin mo, hirap mag-ala tsamba

[basti08]

pag usok and mejo kapos ng power ang usapan... pwede na dyan top overhaul. Sa mausok naming Corolla ganun lang ang ginawa OK na.

[speedyfix]

mahirap magsabi kung ano kelangan dyan unless you show it to your mechanic. its not necessarily the engine itself, baka naman sensor na nagmimissread kaya mausok and mahina hatak. having it estimated here sa forum or via text without actually showing the car is a sure fire way to confuse yourself. bring it to 1-3 mechanics and get different opinions so you know how you should go about the repair.

Going back to Engine Basics: We know that in order to produce Power, the engine needs 5 things:

1. Air
2. Fuel (correct quality and quantity)
3. Spark/Ignition (Diesels: Crank speed, Heat, and Pressure)
4. Timing
5. Compression/Sealing

Defects in these five areas = Power and Torque Shortage, Bad Smoke, and Driveability problems.

Engine Diagnostic Tests will try to identify errors in these areas in an attempt to restore the car muscle, or pass the emission test.

Overhauling involves a pretty amout of pure mechanical work and largely because the engine is 'may singaw' (Leaking) or 'basyo' has a weak compression. Obviously to confirm, Leak test and compression test will be performed.

Computer scan of OBD II equipped cars, from 1996 and newer cars, is capable of identifying the misfiring cylinder and to tell if it is due to errors in 'Air', 'Fuel', 'Spark', or Timing.

For Leak and Compression tests to be helpful, the person that will perform these must know well what he is doing, the procedure as well as the interpretation. I have seen these test performed by a 'nobody novice garage helper', kakatakot.

So, you are now convinced that you need a 'Top Overhaul' or..... are you really sure it is not a 'Full Overhaul'?

To be continued, by anybody.

to answer your question... i am not convinced. because its not my car. if its me, madali lang yan. i would go to speedyfix for a test. and if he recommends a total overhaul, papa-overhaul ko na....

kaya lang, di ako ang may ari ng kotse. kaya hindi ako ma-convince.

[[archie]]

para sakin, isa lang solution diyan... go to speedyfix and have it diagnosed. kahit 1 year or 6 months lang gagamitin tapos benta, mas ok na nasa condition pa rin oto kasi gagamitin pa din naman eh.

tama si 1d4lv, hindi niya hawak yung decision kaya nagtatanong lang para sa kapatid niya.

kaya if your sister is viewing this thread now... speedyfix is the place to be for car repairs... peace of mind kahit hindi pinakamura.. pinakasure naman.

good luck!
