same with me, when i started loosing quite a few engine oil and a few blue smoke sa exaust(My Xe is now at 210,000kms), i had my 2e engine checked sa CASA then told me na overhaul na daw. 50k estimate. hindi ako naninawala. i accidentally met ang isang mekaniko na nag hohome service, sabi nya, normal problem ng 2e are just the valve seals. And, totoo nga. when we opened the engine ok pa pala yung piston rings ko. i only spent 5k for the parts and labor. 6 hours lang nya ginawa. look for a trusted mechanic. enjoy driving...
