Isuzu Dmax Owners [continued]

*michaeltoks: While driving, I didn't notice if it was spewing or emitting black smoke. Pag nakiki convoy ako noon, I asked kung may nakikita silang black smoke, sabi nila sometimes paminsan minsan pero nawawala din daw.

Pina rev ko din, pag dahan dahan, normal smoke ang lumalabas, hindi naman ung super black. Pero pag binigla nung nagri rev, un, medyo maitim.

Ganyan din ang ginawa ng mechanic ng Central Diesel, Slowly stepping then biglang baon ng gas pedal, doon, medyo maitim. Pero pag slowly lang, wala naman.

For sure meron yan lalo pag nagchi change gear. Once the CEL/MIL lit up on your dash, you could feel that the engine is restricted. Restriction requires harder press on the gas pedal. So the harder you press, the higher the rpm goes and it will emit black smoke especially if suddenly change to a lower gear.

*rna800, sir thanks for the reply, The 2007 dmax 4x4 LS at 680k is 85,000kms old dmax with 4jh1 engine just 3.0 turbo intercooler, not yet crdi, the 2008 model is 4x2 LS 4jj1 engine crdi 700,000 with 100,000, kms mileage. pero parang gusto ko yung old model, hindi masyadong complicated ang engine kasi not yet crdi, tama ka feeling ko? pls help me also other dmax owners. Thanks.

*nabig8: Yes sir, 100k kms and 5 yrs nadin ang service sa amin ng Dmax namin. Sulit na sulit nga. Kung gusto ko ng speed, kaya niyang umabot ng 175 kph, kung may bubuhatin na mabigat, itapon ko lang sa bed regardless kung ano un, kung may mga steep climbs, kayang kayang akyatin regardless if it's loaded or unloaded. Yan ang gusto ko, walang arte.hehe

As to the sounds, annoying talaga yang mga unusual and weird sounds. Pag may weird sound kasi, ibig sabihin gagaan nanaman ang wallet mo dahil gastos nanaman.hehe

last oct 26 inakyat nmin sa banaue via sta fe nueva viscaya medyo gabi na may sinundan ako hilux punong puno sya pero lakas din umakyat... sya ginawa ko guide kasi di ko kabisado yung daan malamang 4x4 yun ang bilis eh kahit akyatan at zigzag yung daan, bumuntot lang talaga ako nag slow down nalang ako nung sa patag na he he he.

Malakas talaga ang Hilux, sir, lalo yung 4x4. Sa paper pa lang, talo na ang Dmax sa specs in both hp and torque kaya kahit loaded siya, matulin padin yan. Tulad din siya ng Dmax na maganda ang distribution ng torque so swabeng swabe din siyang patakbuhin sa akyatan. Pero per my experience, kung hindi lalagpas ng 185 kph ang takbo ng sinusundan mo, bubuntutan ka lang ng Dmax. Makiki alam na kasi ang speed limiter and ibababa niya ang speed kaya kahit anong gawin mo din, di mo siya mauunahan. Kung winding or rough road pa at reckless ung driver, baka maunahan ka pa ng Dmax. More than 185 kph, diyan lang mag uumpisang lalayo ung sinusundan mo. 200 kph+, tutuldok ka na sa rear view mirror niya.hehe

Meron din akong naka sabay ni Hilux 4x4 sa NLEX noon. After the Bocaue exit, walang cars masyado so I decided to punch the gas pedal. Nung 160+ kph na ako, meron vehicle na naka yellow light na palapit ng palapit na nakikita ko sa driver side mirror ko. 175 kph, my truck maxed out and tinabihan na ako and that's where I saw that it was a Hilux. Nauna siya pero siguro nag interfere nadin ung speed limiter niya kasi di na siya lumalayo. Mga 5 buses siguro ang gap namin. Feel ko din ang high speed nung time na un so I stayed in the 160 to 170 kph and siya din siguro, gusto niyang mag mabilis, so naka buntot lang ako sa kanya until we reached Cloverleaf in EDSA.

*elcapitan: Sir, wait for the reply of sir d_mac. He has a chip installed in his truck. But I think his is a RaceChip Pro.

*Uncle Nick: What do you mean by "your Isuzu dealer?" Did you mean all Isuzu Dealerships or Isuzu Commonwealth? But I am gonna inquire in Isuzu Commonwealth too. What I don't like is you know in dealerships, their prices are so exorbitant so as much as possible, I don't want to buy any accessories from them. But thanks for your input.

*dreamgame: 4JH1 or 4JJ1, kahit anong engine pa siya, kung di mo siya aalagaan, same lang na magiging sirain siya. Mas ok para sa akin ung 4JJ1 kasi commonrail na siya so that means, mas refined na ang takbo niya.

Hindi naman sobrang complicated ang DDI Iteq. If I would based it on my experience, 100k kms ung natakbo ng truck ko and more than 5 yrs na, wala namang complicated parts na napalitan. Bushings, brake pads, belts, SCV, EGR, water pump, timing gear, etc. Yang mga yan. Meron bang complicated diyan? Ang complicated ay ung price kasi medyo mahal.hehe Pero sa parts, madami naman pwedeng bilhan. And sa mga solutions, andito ang Tsikot where the members are very helpful in giving pieces of advice kung saan shop, DIY, etc.

Ang medyo complicated lang ay where you gas up and what type of oil you use. Pero kahit luma or bago naman ang model ng auto mo, hindi ka naman siguro magpapa fill up sa gas station na binabaha. Siyempre pipiliin mo pa din kung saan ok. Ganyan din sa oil, mas ok kung fully synthetic ang gagamitin kaysa sa mineral oil lang.

Always choose what's best for your car so that it will serve you well too. Kaya kung ang dilemma mo ay ung complicated sa di masyadong complicated, don't dwell on it too much. Ang isipin mo ay kung paano mo siya aalagaan when the time comes that it will be in your possession already.

I live in the Provinces and only deal with Isuzu Cabanatuan. I became friends with the Parts Manager and he gave me an Isuzu Accessories Catalogue issued by Isuzu Motors Japan. My assumption is that this is available to all Isuzu dealers for their customers....it is a sales tool for them.

From the catalogue, I purchased an Isuzu Clino Meter as comes standard on the Boondock Dmax, and had it installed by the dealer so as not to affect my warranty.

Ask at an official dealer for this free catalogue. It contains many other interesting accessories.

Of course they are expensive because they are quality built....just like Isuzu vehicles.

Ciao!

Uncle Nick.

Pano nilinis egr mo? Ung tubo lang ba nilinis o pati ung pinag dugtungan ng egr? No idea kasi ko... balak ko palinis egr ko pero di pa naman nag uusok dmax ko! Sasama ko lang sa pms ko!

**rna800** · November 5th, 2013 02:57 PM

Thanks, Uncle Nick!

*michaeltoks: Hindi ako ang naglinis and wala akong idea kung paano linisin. Kaya dinala ko siya sa Central Diesel kasi naglilinis sila ng EGR. Meron pang isang shop sa Banawe that does that service, naipost ko na dito un and I forgot the name, Isearch mo nalang.

Sorry to say but Isuzu dealerships don't offer EGR cleaning. Palit lang ang alam nilang solution. Nakakatawa nga kasi after kung pinalinis ung akin, nag inquire ako sa mga dealerships kung naglilinis sila. Sa Isuzu EDSA/Balintawak, sabi nung naka usap ko, di daw pwedeng linisin. I asked what will happen pag nilinis, sabi naka ilaw pa din daw and sira pa din. Ok nalang ung sinabi. Di niya alam na pinalinis ko ung akin and bumalik naman sa normal.

Hirap talaga pag papaniwalaan mo lahat ng sinasabi ng dealership. 19k+ din kaya ang price ng EGR.

Sir rna800, you mentioned that may hinigpitan lang sa may belt area at nawala na ung squeeking sound? Do you have a picture or a description of how it looked like and where located? May squeeking sound kasi yung dmax, tingin ko belt or tensioner bearing pero baka makuha din sa tightening.

Gusto ko din i pa check up sana ung under chassis, kasi may naririnig akong mahinang kalampag on road patches and small uneven roads, pero everytime pa check ko sa suking shop, puro wala, okay pa etc., plus meron din nanggagaling sa likod pero i cant pinpoint it kasi when fast turning left lang sya may tunog. Can you recommend a good under chassis specialist? Preferably south area pero kung mahusay tlga kahit dumayo ako okay lang.

Thanks.

**rna800** · November 6th, 2013 09:22 AM

Hindi ako sure kung anong belt doon ang hinigpitan nila. May A/C belt din kasi doon. So either one of those belts or all those belts. Yes, they just tightened it and nawala na ung swishing sound on startup and when turning off the engine. Nasa front part ng engine ung mga belts na sinasabi ko, ung malapit sa radiator.

I don't have any recommended under chassis specialist that I have personally tried for my Dmax. Everything is done in the dealership. Ipa check mo nalang sa dealership. Pwede din baka hindi sa under chassis. Baka there are parts of your truck that need re-tightening like doors, hood, etc.
