Kung complete overhaul ang makina na sinasabi mo Palit lahat piyesa ng makina at maayos naman ang pag kaka overhaul . Parang bago ulit makina mo at kailangan i break in dahil hindi pa naglalapat ng husto ang piston at valve. Kung maganda ang pagkaka break in ng sasakyan mo magiging maayos ito.

September 5th, 2009 05:26 PM #3there are 2 kinds of usual overahaul, major overhaul and minor overhaul. minor overhaul usually, the engine is not pulled out of the engine bay and only the cylinder head is taken out for inspection for parts to be replace or just recondition. also piston are pulled out and piston rings are only replaced. sometimes connecting rod bearing and main bearing is also replace or just re-installed again if still on its specifications.
major overhaul on the other hand,the whole engine is pulled out of the engine. a complete major overhaul usually replace all worn parts of the engine like piston ring, liner, valve, valve seat, valve guide, connecting rod bearing main bearing, all gasket or so called overhauling gasket set.
other mechanic just replace the piston rings, and if the cylinder liner is worn they just inverted it. others usually replace main bearings and use the old con bearings or replace con rod bearings and use old main bearings. others just grind the valves.
a complete replacements of all internal worn parts of the engine makes it a good overhaul and the engine good as new and ready for another brake-in.

Tama ang sinabi ni kapatid na Bennisiozo. Mine was a major OH. 3 days kong pinaandar sa garahe (well-ventilated naman) 5 hours/day then took it for a ride sa province (275kms) averaging 50kph only with the AC off. It was way back in 2001. Until now, walang usok or abnormal oil consumption. I guess it's back to new after the OH.
Aside from mausok at konsumo ng 1 liter of oil / 100 kms, pwede ding sintomas ng engine loose compression ang hirap i-start (considering the starter and battery are OK) esp. sa umaga.
