Interference engines? - Toyota Tundra Forums : Tundra Solutions Forum

I am wondering.... are the I-6 engines in the 1991 to around- 1997 Land Cruisers "non-interference" engines? Meaning- if the timing belt breaks, will it not cause engine damage? Did a search, without results.

Thanks.

91-97 I6 engine in L/C's have a TIMING CHAIN not a t-belt.
If the chain breaks, yes it will bend valves along with alot more damage.

Thanks. I was unsure if it was a belt or a chain. Bad news about being an interference engine though. Sounds scary. I will double check to see if the one I am considering has been changed or not. I think I am going with Tundra anyway. Thanks again!

Timing chain breakage is very rare in these rigs. Even at 300k+ the problems usually seem to be either headgasket, PHH (heater hose at the back of the head) and birfield/cv joints.

You'd be better off checking on the headgaskets and the heater hoses. Go to IH8MUD.com - "The Truth is in the Rocks" and search the 80 forum for "phh"

You can check the cv joints by driving forward with the wheels turned left then right. If they clunk-clunk-clunk turned either way they could use some attention (but you'll probably be okay if you're going to keep the truck on-road all the time).
