hindi po, It's a Townace 2.2 TD. there are few Townys that are 3C-T, most of them are utility types, some are passenger types. my father's towny is a utility type 5-door.
---hmmm... kinda rare...

I decided to take the problem to my own handsand looked on other 2C-T townys here and copied the lines. and I learned that the #3 or the vacuum pump located on the top, is the same with 2C-T's located on the side. #3 has also has a connection on the side which cannot be seen on the picture.
---located at the side= the back of the alternator

ang papa ko kasi ang nagpa service dun and the peeps there ain't friendly. they just charged him 2400K. I also decided to adjust it by myself by 1/4 of 1 whole rotation and increased the Idle. and realized mababa pa pala ang Idle screw niya compared to the picture and the towny's I saw here.
---2.4th lang? baka may minor stuffs lang ginawa. major injection pump repairs cost around 10th. sorry pero i am not expert regarding injection pumps. you can bring it to denso banawe in front of childrens hospital to have it checked. staff and crew are ok...

I'm still evaluating the changes and the noticable change is, now I can hear the soft whistle sound when engines reaches 1500rpm. I assumed it's the turbo but i can't be sure since my dashboard doesn't have the turbo indicator like other townys. before kasi, i will only hear the whistle randomly and really soft that I can barely hear it. still observing the fuel consumption...
sa ginawa ko, I'm hoping walang mangyaring masama sa sasakyan ng papa ko.
---wala naman siguro. symptoms will arise kung may mali kang ginawa. kaya observe mo...

anyway, maraming salamat po sir! may natutunan po ako sa inyo
---no problem. marami dito taga tsikot ay matulungin. salamat.
