Vitara 1991 brake booster replacement

[fixkick]

Hello,



Oh that was a lot of information. I will definitely go trough all those steps to find the leaks. Ofc when I return to civilization I first need to order all the TB gaskets + new brake booster.



Anyhow today I hiked to the car and took some pictures. I am parking it VERY far away from the farm yard as it might still be dripping some oil either from engine or transmission. Recently head gasket replaced, transmission seals replaced, front and back differential seals changed. I don't want the oil to go to ground and get into our water well as this place depends on it for drinking water.



Anyhow here is a picture about the broken off "knob". If its really a filter, then I guess I need to either find replacement for it, or try to make some self-patented-filter over the broken one to stop dirt getting in.









Also I am fairly certain the booster leak is blocked now. The rubber tube from booster to TB looks to be in very good condition considering its age. Also other hoses still "look" ok. I am guessing they degrade lot slower here as Finland has lot less air pollution than USA (in general, Alaska might be the odd one ). And my car has spent most of its life in northern finland where its cold like in Alaska and population density is very very low.







I put the ODB in diagnostics and got CEL code 12. All OK.


Also the car was sucking oil a bit when I bought it last year. I was thinking that in addition to leaking it from broken head gasket it would be burning some of it, but after replacing head gasket I have not been able to see any oil missing after about 700 miles. So I guess internally the engine is in quite good condition. (Considering it has ran 152000 miles already). Ie the km based meter has turned around/over 2 times.





Thank you for all the information. Do you have some crypto currency wallet I could donate a bit of currency for all the information and maintaining this forum. Its like a gold mine for suz info

ps. That movie is a good example of vacuum, though I understand vacuum (and pressure without the example). Had to took quite many physics courses when I studies Msc. Information technology, even tho I have never actually needed physics in my work.

for sure forgive me telling about vacuum. to you, I understand about that.
for sure vacuum leaks are hard to  find, as  are oil leaks (due to wind-age, effects)

yes, customs fobar, sure avoid this.... thanks for heads up.!

that  CAP is only the filter broken off if the casing below is no cracked,
it is a filter so when the valve cycles  it sucks  in clean air only.


that booster hose plugged up , ends all brake diaphragm leakage for  tests sure does.

the IAC can leak too hot.  this old easy. (thermal IAC)

and molested screws, too.  4 of them. TV/DP/Bleed/ISC 5mm)
best is not touch those screws. but sadly get that way, this old ,for sure any CARB guys touching EFI. (oldskool screw fiddlers)

good code 12.  means no sensors dead.
good luck to you !!!
I too love physics, and is why I went the electronics career.  (still learning , endless)
