Mga sir. I just want to get an idea kung how much ang general overhaul ballpark figure with parts and labor.

2007 Toyota Altis 1.6G A/T

What happened:

I just had the unit serviced at Toyota Makati for 105k PMS bale change oil/filter (semi synthetic), brake pads and serpentine belt.

Knowing na naka condition talaga yung unit i brought it to baguio pag dating sa baguio biglang umilaw yung oil indicator so i stopped at the nearest gas station to check. I shut off the engine and check the oil. Ok and level ng oil sa dip stick. When i try to start it again ayun seized na. Ayaw na umikot yung crankshaft. All other things are intact naman. Nakakapagtataka talaga.

I had the unit towed from baguio to makati and upon checking Toyota Makati saw na luto ang ibabaw sa cam shaft. But final diagnosis is yet to be given until maibaba yung engine.

My question is nasa magkano kaya aabutin ang engine overhaul?

And saan ba mas ok ipagawa? Casa parin ba or sa trusted talyer?

TIA mga sir!
