Watch out! Many Japanese products use timing belts with non-free running (interference) engines. When, not if, the belt skips or breaks, your engine and $8,000 is gone. Even if you get through the warranty period, the resale takes a big hit because the word has got around. |

Most members of the general public don't even know what a timing belt is. Suzuki is an exception. Their cars are okay. Yeah, like you know. Like it's not trolling to multiple post this in honda, toyota, nissan |
Kind of like the number of post mid 90's model 4 cyl. Nissans offered
for sale on web auctions here, where the owners claim that the timing
belt has just been replaced...

uninformed and never-the-less opinionated troll crap deleted ... ... double OHC engines are safe design. |
when does a timing chain solve the "problems" with belts? Ever heard of
timing chain chatter?

What happens with a stretched or broken timing chain? |
teeth get worn as well. The chain starts to chatter, and the valve timing
goes off a bit. Timing chains seldom if ever break unless the lubrication
system fails, at which point the chain gets REALLY noisy. If left long
enough, the lubrication failure may affect the cam bearings or even main or
big ends. I've never seen a chain break on the old BMC A and B series, Ford
Cortina 1500/1600 engines and an E-type Jag engine I worked on years ago.
Just about everything else let go, but not the chain ...
An severely overreved engine would sometimes stretch the chain and throw the
valve timing really off.

timing belts all in all, quieter, better valve timing. I've never seen
a chevy V8 that didn't have a lot of slack in the timing chain after 80K
miles.

forums I frequent are right around 200K miles and have not had timing chain
problems. There is no schedule for changing the chain, either. Disclaimer -
not enough data for a positive answer yet.

I prefer gears. My 1964 Studebaker P/U 289 has over 300K and the timing
is fine...

Newer timing chains appear to be much improved. Several people in the Prius forums I frequent are right around 200K miles and have not had timing chain problems. There is no schedule for changing the chain, either. Disclaimer - not enough data for a positive answer yet. Mike well, chains work, but belts are a better technical solution. particularly for high performance engines - less momentum and angular velocity fluctuation. don't forget, design criteria these days are all about life limitation and cheapness - chain wins on both counts. |
I guess it comes to how well built the motor is, belt or chain. Fact
is, Nissan VQ V6es are legendary, reliable timing chain motors. They
just don't die. Even the SR20s, KA24s and GAs seem to hold up quite
well. All timing chain motors. Honda and Toyota make great, long
lasting timing belt motors.
