I have owned my 99 Land Cruiser for 13+ years now, and now that my rig is 17 years old I have come to appreciate having a timing belt on it. I am somewhat anal about car maintenance, and I like that the old 4.7 is Designed to have its timing components serviced, vs being "lifetime". There's a sort of peace of mind knowing that the belt, tensioner, and various idler pulleys have been replaced.

Now for those of you who think I'm crazy, I had the unfortunate experience of owning a 2003 Range Rover. The single worst car I ever owned! I spent many thousands of $$$$$ getting everything in perfect order when the timing guides gave out on it. This caused the motor to be toast which made me sell the car at a big loss. I also own a 2008 Dodge Ram, which the original owner had to replace the motor at 60k due to a broken timing chain.

So it begs the question. For those of us who choose to own older vehicles (and plan to keep them long term), could a vehicle with a timing belt be a better choice? Yes, a timing chain is considered to be maintenance free, but can it be counted on to go 300-400,000 miles on the original chain? I know that timing chains can be replaced, but that seems to be rarely recommended if ever.

I'm not trying to say timing chains are a bad thing, just wondering if anyone else out there has considered that timing belts (which Toyota appears to have abandoned?) may not be altogether a bad thing.
 
IMHO chains are better. But, you need to follow FSM to check the chain so it's still in spec. Belt and chains can both go the same milage, but if the chain is in good shape you can reuse it. The belt you can't. Anything can fail and a range rover is just a s***ty vehicle to begin with. I like both chains and belts though and think it's more personally preference
 
It depends.

For the most part (at least in tge 80s and 90s) Toyota put chains on engines that are interference and belts on non-interference engines.

A chain isn't lifetime, doesn't matter what a dealer may tell you. They, and especially the guides, can wear/stretch and really should be changed. Some engines, like for SBC, you can do a chain to belt conversion... but I don't see the point considering a double roller is cheap and those don't use guides.

I wouldn't want oe of those three chain nightmare VW engines, though.
 
To me, for the 350 , this is better. Timing gears.
