Brought my old car (singkit 4g15 efi) to a shop. It is releasing white smoke upon cold starts, diminishes when engine is warm, billows smoke when engine is revved up or when AC on. The oil on the pan diminishes when checked but no sign of leaks. Smoke smells of burnt oil and brownish burnt cooking oil like deposit on the tailpipe is present. But gas consumption is still ok at 11-13 km/li considering the car is 18 yr old. No big problem really with performance but more concerned with the embarassment of the blanket of white smoke upon start-ups, or idle and the hassle of having the hassle of checking and topping oil every so often.
A mechanic quickly suggested a top overhaul with the following quotation: labor 3800, seals 1250, head gasket 2500, machining 9500, valve guides 1500 totalling almost to a whopping P18,000!
I was thinking more that it might require only a valve seal replacement.
1. How will I know if only valve replacement is needed and not TOH? should i give in to this price?
2. How much will valve replacement cost?
TIA
