parang tunog taxi ang makina, may kumakatok pag umaarangkada..

Try using a higher octane fuel... see if it eliminates the engine knock or tope. Usually older cars require higher RONs.

Try mo muna ibang brand ng unleaded, or sa ibang gas station... baka lang naman. Kasi naalala ko yung Revo nung boss ko may tope nag try syang mag-Caltex Gold (instead of Silver) nawala.

yung air-fuel mixture po ba sa carb ang adjustments noon?
if yes, natune-up na po ang aking carb last sunday.

Try mong magpakarga ng same fuel sa ibang gas stations (preferably newly opened ones and not located in flood prone areas), kung di umubra, try higher octane gas. Also, nung nagtune up ka, nagcheck ba ng valve clearance?

[cocoy_01]

di po ako sigurado kung na-check yung valve clearance eh..ermat ko nagdala ng auto sa mechanic.. pano po ba ginagawa yun? is it as simple as checking/turning some screws o kailangan buksan makina to check/adjust valve clearance?

[nicolodeon]

Kung malapit ka ng magpa-tuneup ng kotse mo, ipasabay mo na yung valve timing, clearances at air fuel mix.

The EL should be able to take regular 93 octane AFAIK. As the others mentioned, try gassing up at good station (Caltex, Petron, Shell)...

Mura lang magpa-check ng IGNITION timing. Just look for a service station/mechanic with a timing light and make sure he knows what the stock setting of the Lancer is. If it still persists, then you try upping to 95 octane fuel.

TO check valve clearances, they open up the engine but this shouldnt result in detonation/tope really. Valve clearances that are off-spec usually results in more enging clatter, not "tope".

thanks! the tope is gone, hopefully.. feel ko, wrong shifting lang ang problema.. medyo kinakapa pa kasi ang tunog ng makina..napapaaga ata ang pag-segunda ko.. post na lang kung ano pa mangyayari..
