Okay,I'll need confirmation for the questions listed below:
1:Is 180000km on a 4age considered a high mileage engine?How many km will it last before it requires a full overhaul?Hope i can get a rough quote from experienced owners from this thread.By rebuilding I'll do it all at once with valvetrain and cams when all things are set(cooling,drivetrain,footwork on par)which is a long way to go.For now I will steer clear from power upgrades.
2:Any recommendation workshops in or within KL?
3:Any known issues with the 4age blacktop(engine wise,aside from chassis),what to watch out for and to be aware of.
hope I can get my answers so I'm able to make my next move.waiting for the green light.thanks Pardon me if I misled
visitors cause of the word.I'll be more careful next time.
6yrs back when i was in corolla scene, there were so many 4age sifu in Zth. I think most toyota enthusiasts here had gone in the wind. Back to your question, if engine still not eating oil, plug is clean no oil, valve cover no oil leaking, whp still around 130-145 basically can ignore overhaul.
4age is just like any NA engine. if you din't go for track, as long as use full sync oil is fine. Owned the car for 2yrs and it was my daily drive to work, family outing, travel ipoh kl multiple times. So far no major issue. Mine was 6spd and it got synchro problem from gear 1 to 2 during cold drive. Swapped another 6spd. That's common issue. If i still recall minor issue like map sensor kaput, O2 sensor kaput, and ecu component fried(common issue). One Zth toyota taiko know how to repair instead of buying from halfcut.
As for workshop, famous one like kegani and trial tuning(if not mistaken very less 4age kaki go there anymore). Mine always service at puchong ah wai. Also specialist in all sort of toyota.
