my car got 2 leakage problems which are master cylinder and oil .
was told by the workshop says that i got oill pressure problem need to change and oil pressure switch... anyone has idea or experience about it? or know the fair price for repair? or i can just do it myself???

 

#1: if the SHOP says you have a master cylinder leaking and they do not know what to do,then Get it OUT of that shop.
Needs another master..remove and replace.
#2: State what the Oil pressure problem is,maybe someone can give you advice on that.

 

i can see some leaking but just a little around my oil filter.. but the guy worked on the shop was telling me i need to change a oil pressure switch...

 

sounds like mr clueless to me,best $$ you can spend rt now is on a haynes manual,yes DIY all the way,if the car has been sitting along time and not driven,the clutch and brake m/c have a tendency to go bad,symptom i usually get is no pressure being created to activate brakes or clutch,again,the haynes manual has a breakdown on symptoms and poss. causes for all the diff. sys. of the car
