Well, still monitoring the fuel consumption but so fa so bad... O2 sensor did swing up and down, the voltage fall below 0.1V but not over 0.9V  (the good sensor should between 0.1-0.9V right?) full tank goes only 400KM or less as of now still.... its could be coz of my exzos leak (few small holes at the bottom exzos (the fat part), wondering can do repair or need to change the said piece???

Yet to have time to jack up my bold to inspect the bottom to see what's leak, will do it soon. The oil seals u mean its attached with the engine bloc? How much would cost to get it replace? Any recommend foremen in Penang that u usually go for ur bold repair? Previously the OCV leak and I DIY to change the O-ring.

Hose oil feed is the smaller one, right?

Anyone managed to changed the hose by diy?

Viewed one video, the mechanic took out the alternator first before changing the hose..

are you planning to look for something dirt cheap?

cause i see in lazada it's pretty cheap buy from this stall and go to his workshop to have it installed.

tam turbo available at ipoh, penang i dont know... but prepare at least rm3k (mine 2.6k all in), after changing to new turbo, my crank sensor fault. just make sure the pomen install crank sensor cable within its laluan. if not mesti rosak because cable akan koyak.

mine 2.6k including new turbo unit, new engine oil, new turbo hose and labor for cleaning oil sump and upper engine parts as the engine already tersumbat. i replace at tam turbo because they can settled for 1 day. other place need 3-4 days to settle

remote battery weak

After u pull out key, notice the dash, quite likely there's an indicator for remote low battery like blinking.
