I like inline 6 designs. That particular Ford had/has a great reputation.
I think the problem with 'em was they lasted too long !

+1 Once they put FI on that engine you could hardly kill it. I'll take a belt drive or gear drive any day over chain. We just replaced a belt on a CRV that had just shy of 190k on it and it was still in good shape. I have replaced more timing chains than I can count. I can't remember the newer dodge engine in a pickup that has chains driving overhead cams but I will never touch another one of them. CJ

What year CR-V did you replace the timing belt? My friend has a 2005 model with a timing chain and it is still humming along at 280k+.
I think some of the newer direct injected vehicles wear out timing chains due to oil dilution/lack of lubrication.

After about 11 years and over 130k I finally did my Tundra. To be honest, I'll never change it again. The belt looked fine. I really only did it because I was worried about the water pump (driven off of the T-Belt). I was expecting to see cracks in the rubber but it had none. A coworker had his done on his 2003 Tundra when they changed the frame. It had over 200k on it. The dealer was trying to hustle up extra work. Since the belt was going to be easy to get at they could offer to replace it and the water pump they were offering discounts to do the work. I would say replace the belt with a high quality one, I bought the oem. The only timing belt I have broken was on a 1990 Celica. The AC compressor locked up under warranty and the accessory belt snapped and broke through the T-Belt cover.
My new Toyota has a timing chain that's designed to last the life of the engine. I think it's about 250k. Of course it also uses synthetic oil which should help prevent wear.

Otherwise known as before or after the belt breaks.
Like buying a generator.
B4 or after a power failure.

I changed my V8 2005 Tundra at around 93,000 and noticed it ran and idled much better after the change. I used a Toyota belt and changed the water pumps at the same time.
T-belt driven water pumps can seize. So can Idlers, Tensioners.
Can we possibly load more chambers, in this mechanical version of Russian Roulette ?
Some manuf. do seem to over-design / under-stress their Tbelt applications.
While I do like chains, I much prefer them short - modern OEM practices of wrapping the chain half-way around the engine compartment, then beating the heck out of your supplier on price don't impress me. GM was getting enough chain-stretch on the Torrent class V6s that they had to do an emission recall.
Aside from bad oil, or DI contamination, another problem source for chains is cheap or defective oil filters. A faulty Anti Drain Back Valve can take too long to build oil pressure at start-up. Bad news, esp. if the cam-chain is hydraulically tensioned.

Chains are fine...if they are short. All makers are having problems with those LONG DOHC timing chains and their tensioners, some at less miles than belts last.

I had one where the tensioner pulley came apart and walked out through the front of the timing cover. The worst part was that it was 2 miles from the shop where it was going to get a timing belt and headgasket change.T-belt driven water pumps can seize. So can Idlers, Tensioners.

(Knock wood) I can have that kind of luck.... :duh: that's part of why I don't buy lottery tickets.
A couple of Winters back, I heard a request for assistance on one of our local 2m repeaters. A local ham was heading down our version of an interstate, when his not-that-old TDI died.
Even for Feb. , it was a pretty good cold snap - so when I couldn't raise anyone at his house, I got a tow truck on it's way to him. Not a night you would want to be sitting in a car with a dead engine for long.
(For those of you who don't know older ham radio guys...... they are infamous for not spending money; possible exceptions being 2 way radios, and sometimes vehicles. The dead-TDI owner didn't own a cell phone).
On the radio, he said he thought the engine computer had died, from the way the car shut down.
Saw him a few months later........ as you may have guessed (a few paragraphs ago :laughing
, it was the timing belt that broke.He hadn't considered that possibility when sitting on the side of the road, as he was something like 700 km below the mileage where the change interval allegedly was.
When you come across incidents like this, it sheds some light on why Honda derates my Civic belt for harsh climates.
