2000 Chrysler Grand Voyager 3.3L Engine Timing Chain
Hello all...
Recently, my mother's 2000 Chrysler Grand Voyager van (195,575 or so miles on the clock) seems to have jumped out of time. It was going down the highway at the time, probably about 45-50 miles per hour and it just quit. Subsequent examination shows that the engine is very clearly out of time but it will try to run, albeit very poorly. This experiment was only attempted once, and the engine only ran for about three seconds before stalling. The rhythm of the starter motor is also very clearly off. I read through some old posts here and it seems like the lifespan of the chain should be about 200,000 miles. Okay, fine. I won't argue with it over 5,000 or so piddly miles. Stuff happens. What nobody ever seems to say one way or another is whether or not the 3.3L V6 engine is an interference engine design or not. People have asked and the answer that comes out is "why does it matter, the chain is good up to 200,000 miles". Well, that's fine, but if it slips or fails at that magical point, one needs to know if the engine can simply be retimed, the chain replaced and everything goes on as it did before...or if repairs to bent valves and such may be required. That's why it matters! The van ran fine before this unfortunate incident. I'd also like to know how much of a job it is to change the timing chain. Is there anything in particular to watch out for? Things that should be done "while we were in there anyway"? Many thanks to anyone who can shed some light on this. William |

It's an external w/p driven by the FEAD belt. |

Hi!
> I don't know this engine at all, but is the water pump driven by > the timing chain, or is the w.p. accessory belt-driven? It's definitely driven by the accessory belt. My brother and I were on a pretty good roll replacing the Autozone remanufactured water pumps. After the first three (all the same failure--each one started weeping water out of the weep hole) went bad, we just got a new one and it's been fine ever since. William |

I went thru that with an alternator one time at Advance - after the third failure, I finally asked for my money back and got one that did cost more at NAPA, but it never gave any trouble. -- Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x') |

That's why it matters! That engine is not of interference design. It an old fashioned cam in the block with push rods design; not even overhead cam. I sure wouldn't run it with the timing off though. http://www.allpar.com/mopar/33.html http://forum.chryslerminivan.net/showthread.php?t=8817 |

According to http://en.allexperts.com/q/Chrysler-...intrepid-1.htm it is an interference design (though I've got no idea how much credence to give that site). -- As we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously.

I went through that with Pep Boys and an A/C compressor for my '84 Caravan. They went through three of their stock units, each failing within 2 weeks of install. I was fed up and complained to corporate. They went down to the dealer and got a MOPAR original part. Worked fine as long as I owned the car. No cost to me except the original job order and the aggravation. |

This is where I think NAPA does an infinitly better job in controlling the quality (parts and assembly) that comes out of their suppliers. I have developed a philosophy over the years on dealing with this: On critical items, I compare NAPA and the others (which all seem to use the same rebuilders, except NAPA may or may not use the same rebuilder). Where NAPA is clearly using a different supplier (which I now automatically assume is for quality reasons), in general it is worth the extra price they may charge. On an item for which NAPA is using the same rebuilder as the others, that is a sign to me to go with lower price - for example, *all* the chains use the same rebuilt brake booster part for 2nd gen LH cars. NAPA wants $105, Advance wants $85 for the same part, so that part I get at Advance (also, the booster being a critical safety/liability item, a rebuilder and re-seller would have to be insane to skimp on quality on that type of item). -- Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x') |

You say that as though it has ANYTHING to do with being an interference engine. It doesn't. In fact, I can tell you that *many* cam-in-block chain-timed engines are interference designs. There's little incentive to NOT make them interference engines and take advantage of the breathing and compression advantages it allows when the chain generally lasts as long as the rest of the engine, unlike a belt. No, it doesn't make you feel any better if you have a chain break and break a valve (and I've been there/done that), but from a design perspective very, very few of any given type of chain-timed engines built will ever jump time. Conversely, a huge fraction of belt-timed engines will jump time at *some* point in their lifespan because of owner neglect and the relatively short life of a timing belt compared to engine internals, so there's motivation to make them non-interference designs. Frequently the performance advantages win and belt-timed interference engines are built. But that, IMO, is still not a very wise choice. |
