Lose your timing belt, lose your engine
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. Auto makers, heed this warning. The public knows gear, shaft, or chain driven single or double OHC engines are are safe design. Timing belt driven setups are not. Suzuki is an exception. Their cars are okay. |

Nissans offered for sale on web auctions here, where the owners claim that the timing belt has just been replaced... |

Since when does a DOHC engine HAVE be a non-interferance design? Also since when does a timing chain solve the "problems" with belts? Ever heard of timing chain chatter? SD |
Re: Lose your timing belt, lose your engine
What happens with a stretched or broken timing chain? I have 110k miles on 2002 K20A3 and I had belted Honda before this. Still runs great and I guess it was kinda cool I didn't have to do or pay for the timing belt service. What's the downside and eventual maintenance of timing chain? |

First the chain wears ie gets slightly longer, and the cam + drive gear 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. SD |

I kinda prefer the 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. |

Most Toyotas now have DOHC engines, and I believe they are all chains now. |

Word has gotten around about what? Most Japanese Import cars out values their Big3 counterparts by THOUSANDS of dollars for similar model type and year. > Auto makers, heed this warning.

A lot of single OHC engines are interference, Japanese or American. My Chrysler LHS 3.5l was an interference engine. Come back when you actually know something...

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.

My 1964 Studebaker P/U 289 has over 300K and the timing is fine... JT |

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. CD |
