is the 3.5L 6 cyl 1994 LHS an interference engine?
Hi
Does anyone know if the engine in a 1994 LHS is an interference engine (aka crash motor)? It's a 3.5L 6 cyl. Thanks |

The reason behind that is because if the cam rotates while installing the belt the valve could slam into the piston and cause damage. The marks were offset to prevent this. |

This is not a second-generation (aluminum block) 3.5 It is an IRON BLOCK first-gen 3.5- no interference. |

Just let folks that have broken their belts answer and that way there's no confusion. |

I may have read discussions on this in the past in which it was concluded (at least by some) that certain years were iterference, others were not (even though the Gates guide shows them all as interfeence).

The Gates book has its share of errors. (in this case, errors sell timing belts) I've replaced scores of these belts and not a one ever bent a valve. That is more than a coincidence. My Mitchell On Demand lists the 3.5 as a non-interference engine, it also lists the 3.2 as an interference engine. The Mitchell text is direct from ChryCo. The engine has been out what, 13 years now, yet I have yet to see anyone post a complaint of a 3.5 with bent valves in -any- appropriate newsgroup, plenty of incidences posted for other engines that -are- interference though. |
