sir, much better if you'll go to auto parts shop and check for the prices of your parts needed for your car. ang top overhaul kase eh sa pagkakaalam ko eh hindi hihigit for 5k. yung sa tropa ko meron syang sariling talyer, and the cost of their top overhaul for gas engines ranges from 3500-4k, depende pa ata sa model ng kotse. eniwei, many gurus here will inform you kung tinataga ka nila. buti na lang hindi ka pa nag-go signal, hehe..
