SCV (Suction Control Valve)

[Avaris008]

di ako familiar sa SCV pero may na experience ako dati na parang sinisinok pagka shift ko sa segunda. parang di niya alam kung aarankada o mag memenor. parang yumuyugyog yung buong sasakyan. mga dalawa o tatlong beses lang nangyari saka pag cold start lang. pag uminit na, ok na. wala na yung problema ngayon, at baka rin kse shell v-power diesel na ako.

here's the same question i posted sa strada thread. pano mo madedetect yung problema sa SCV? may parang symptoms ba yan? salamat

Bro - did you feel there was a power problem kaya nireklamo mo ang SCV mo? Or nakita nila ito sa kanilang Computer?

Saan mo nakuha ang unit at saan ka nag pa-service?

TIA

red, minimal manifestation lang sir.

i experienced loss of power once or twice between 10 and 15K km odo. but nothing after. just asked the SA to check on my egr and scv during my 20k. technician said the scv was detected faulty afetr computer diagnostics while egr was ok. ayaw na nga pauwi sa akin coz there's no scv on stock, ordering and delivery will take 3-5 days. baka daw mag-stall, but i opted take it home. nagamit ko pa for a week before bringing it back to diamond marcos highway for the scv replacement.

hope this helps.

need your advise mga Sir...
We're planning to buy GLX Strada soon, reading this thread and the Strada Thread, it makes me think twice if we should by now or wait for the 2011 model. Hoping that they already fixed this problem on the 2011 model. Any advise from the current owners? TIA!

Sir i guess it will be the same. if i can recall matagal naring issue itong SCV na ito. pero upto now lumalabas parin. not unless they will have a new face lift after the 2010 model might as well you wait for it. but if not don't wait.

as long as its under warranty you should not worry about it. siguro kaya din di nila ito masydo binibigyan ng pansin dahil din siguro di ganun ka rampant yung trouble ng SCV.

I wonder kung ano kaya ang statistic sa atin na mga naka strada ang nag ka problem sa scv on their 20KM, 30KM,40KM and 50KM. kasi i know some who owns MS and strada na hindi wala namang problem at kung saan saan lang din naman nag papagas.

Sir I have a primary and secondary fuel filter. I make it a point to bleed it every 2 weeks just to see if any water got in. I always keep the tank full or close to full so there will be no space in the tank for condensation from water vapor in the air. IMO 10Tkm is the longest you can go before changing fuel filters with our diesel here. I've changed as early as every 5Tkm. As someone in this forum said, diesel contamination here has more to do with delivery and storage than the quality of the fuel itself from the plant.

My friend has the 2.5 tdci Ranger and had no SCV issues but the fuel pump itself conked out before 50Tkms. Dang.

i believed sir you're referring to the nissan navara which designed to have dual fuel filter. there is no such thing of fuel contamination from the plant, unless the station have old storage tank which caused the fuel contamination of foreign object like water or dirt. problem of our fuel here in the philippines is the quality. how come the europe don't have experienced on their scv problem like here in the philippines. the designed of the crdi cannot be blamed on the brand but to the manufacturer by denso crdi system which they did'nt anticipate the low quality of fuel here. i think that's were discussing of the fuel problem. quality!

Thank you sir for the advise.

I could'nt agree more - I have friends who at this stage are clueless on the SCV issue. Their ODO are already at the 50,000 km without any problem. I did not tell them directly the issues of Strada but I did mention the general problem on CRDI engines in regard to the bad fuel quality in the land. I would like to spare them sa kaka isip -- walang masama na mag ingat but kung isip tayo ng isip na baka tamaan tayo ng problema eh baka hindi tayo mag enjoy -- the best thing is to enjoy every kilometer of our rig. It's just me..

Yes sir, highlighted in red is what I meant by my post. From what I've heard the fuels come from the plant relatively clean and gets contaminated at the retailers' lorries and tanks. That's why I said contamination has to do with "delivery and storage". Fuel quality has more to do with emissions. If you mean by fuel quality the ppm of sulfur in the diesel then how come a lot of Stradas never encountered the same problem? AFAIK they fill up the with the same brands of diesel, albeit at different locations.

Thank you Sir!
Actually decided na talaga ako to buy a Strada.
It just happen na nag back read ako ng mga thread and this SCV issue just keep on poping out. I don't know this issue before.
I guess back reading the thread has a positive and negative effect! hehehe. Anyway I think the Strada is the best truck currently available in our market. I'm looking forward to owning one and joining the club.

Isuzu din ba me issue regarding sa scv?

Thank you sir for posting!

+1 I think that's what every new car owner wants

I'm looking forward to owning one and joining the club.

TSCP really helps in softening out the issues of the Strada, parang customer care group hehe

My 4 year old GLS 4x4 is still running fine. It was one of the first releases still with the 2.5L 4D56 crdi engine. The scv problem seems to be plaguing mostly units with the supposedly newer 3.2L engine which was introduced later. This is the same engine in the current Pajero and Montero Sport SE as well. The delay in the intro of the 3.2L engine was reportedly due to incompatibility of local diesel with the engine at the time.

yup, i agree on that sir.

no idea regarding the isuzu d-max sir.

Dang, sounds like D4D.. I hope he gets warrenty for that.

Yes Navara's Euro3 engine(even the older D22) comes in with dual fuel-filters and i havent heared of SCV failure yet locally. Similar cases of SCV failure in CRDI,s can be found from Australia. There are also SCV failures in Europe even if they are using EuroV diesel, that goes to show higher Euro rating is not a guarantee for SCV not to fail. AFAIK SCV are so sensitive to dirt/ rust. If contamination seized the valve, it deprives the fuel-rail of the correct pressure causing the inconsistent power..

no idea regarding the isuzu d-max sir.

Read the 1st page 2nd post, 2010 Global DMAX SCV replaced twice.

[javee]

Isuzu din ba me issue regarding sa scv?

bro, isuzu dmax user here..nagkaron din ako issue sa scv ko. twice na napalitan, last year and nito lang september. naeexperience ko xa dun sa gas station lapit samin. dun lang ako ngpagas and then ganun na nangyari.kaya now e tyagaan ako magpagas sa west gate alabang and sa sta rosa lapit office ko. biñan area ako.

Re: 2010 Mitsubishi Montero Sport [continued]
Just to share to our MS brods, i have a triton 3.2 the big bro os MS. just today is change the SCV to an after market denso SCV. The 3.2 can not handle dirt in the deisel and even a bio deisel, but with it all is possible. After they install in i had a full tank of B5 (5% bio) so far it runs the same and i dont have a feeling of any problem.

This is the pic of the SCV, flesh color is the stock/standard SCV. Now the blue one is the after market denso.

do you the oem part number of the denso scv that you replaced the stock 3.2L strada scv with??

[dadz]

MGA sir the after market SCV is released in thailand. I been talking to them and dont get me wrong im not selling this product because Denso have a distributor in Philippines. I been talking to them and they say that this after market is only for thailand but the 2009 models of toyota fortuner is using this SCV already yun nga lang we dont know kung kasama diyan sa atin.

I will go back there tom to try to get the parts number so you guys can look kung available na diyan sa atin.

[Ry_Tower]

maybe we should replace our fuel filter every 10-15 K kms.. Fuel filter is the first line of defense against dirty fuel.. I know someone who already replaced his twice SCV twice on his montero sport..nasira ulit because hindi pinalitan fuel filter niya after the first SCV replacement.. also mag pa gas tayo sa mas bago, maraming nagpapagas, o sa mas matataas na mga gas stations..

IMO much better to replace the fuel filter every 10K or every other change oil. Ganito ginagawa ng mga truckers dito sa amin because of the problem with dirty fuels. Mas mura ito kesa sa SCV replacement at hassle.
