sabi sa akin ng mechanic pag naka-overhead cam sigurado timing chain or belt ang gamit...
pag hindi naka-overhead cam, timing gear ang gamit, me push rod at rocker arm...
tama ba ito?

They usually are but it's not a given. Some more modern pushrods use a timing chain... but the pushrods we have locally are typically timing gear driven.

May 26th, 2011 03:49 AM #34hi tnx to all reply to this thread,, as im reading all your reply, chain or belt doesnt much concern while chosing a car if you are aware of your maintenance. any of the two can fail anytime..? cost of changing a belt is not too much, unless pag naputol na saka mo lang papalitan at may kasama ng ibang parts na papalitan.. tama po ba?...

Chain is better, naputulan nako ng belt sa L300, hindi biro ang gastos...
Gear is king, old isuzus use this, sabi nung isang naka isuzu na kilala ko, nasisira din daw, pero sigurado mas mauuna masira yung sasakyan bago yung Gear.hehe

Both could fail at any time, but you're talking a 1 in 1,000,000,000,000,000 chance (chain) versus a 1 in 1,000,000 chance (belt) within the first 40,000 kilometers. Chain failures are such freak occurences that you can usually get it replaced under warranty if it happens. (Tensioners, no. Chain, yes)
If you change your belt around 10,000 kms before the change interval, you're okay. Those belts are designed to last a long time... I know some people who've gone 20,000 or 40,000 kms extra before changing, but I don't suggest you do this... as it's dangerous.
Safest is a timing chain engine that's non-interference. Which means the valves and piston will never make contact, even if the chain breaks.
Ultra-safest is a rotary... which has no valves. You can rev them to kingdom come and nothing will break... at least not until the oil rips itself to shreds and the whole thing overheats. Of course, the apex seals are a pain in the butt and fuel economy sucks... which is why only one company uses rotaries, nowadays.

May 26th, 2011 10:58 PM #39rotaries are actually a misnomer. technically the rotors rotate at an eccentric path, not a real circle so there is still some side loading that will ultimately limit RPMs but yes you are correct that before that happens it's usually the apex seals or engine ancillaries that give up the ghost first.
