kakatapos lang po ma top overhaul iyong XL 92 Corolla ko. Napalitan iyong exhaust/intake valves, valve guides, piston ring, timing belt, tensioner bearing/balancer. Break-in process po siya ngayon (for 4 months then I am required to bring it back where I had it overhauled).

Ang question ko po, what are the things to observe and monitor that indicate there is a problem sa pagka-overhaul?

thanks for the replies. have a good day.
