guys, ano pla mangyyare kung may guhit n ung bore boar hindi ko alam tamang spelling. Un kinakabitan ng piston na cylindrical shape na parang tubo. nadamage kasi nung piston ring sabi nung mekaniko namen.


Kung totoo sami ng mekaniko mo... That means the piston rings have gouged/damaged the cylinder walls. Your options may be:

Kaya siguro mausok, too much oil gets into the cylinders, dumadaan dun sa "guhit"

1. Have your cylinder honed sa machine shop kung di naman kalaliman yung guhit, they would know kung kaya pa. Lalaki ng konti yung cylinder, just a tiny bit to take out the "guhit". Then you might need slightly oversized pistons and piston rings, or just over sized piston rings.

2. Kung malalim na talaga, the machine shop will slightly oversize the cylnder and put sleeves inside the cylinder. Para kumapal ulit yung cylinder to stock size. Then palit ka ng piston rings, regular size na lang.

Bad news lang eh, you should have done these before the top overhaul and oil change. Parang overhaul narin to dude, kung gusto mong maayos yung "guhit" ng cylinder wall mo.

I hope these were of help to your problem.
