Timing belt OEM Toyota or OEM FORD

Just replaced the timing belt on a 25 year old Sienna with 150k miles. Almost pristine. No cracks, very little wear. I was surprised.

I own a 2006 Toyota Sequoia. Bought it brand new. We’ve had very little if any issues with it.

My 94 ranger had 230k on it on the original belt. Looked about like this too, sold the truck in 2018, still had the original belt on it.

My rangers belt was identical to this when I bought it at 210

Sold my 87 F150 Lariat, normal cab, 8 foot bed, 302 2 wheel drive, it had over 450,000 miles, sold it to a drummer, then he sold it to a pest exterminator company! Had 3 different radiators and 3 different alternators, timing belt replaced, otherwise pretty trouble free!

I recently changed a 22 year old timing belt with 230,000 miles from a Lexus gs 400

Pretty much all the newer Ford 4 and 3 cyl crap-box engines have what's called a wet belt for the timing. It's inside the engine as opposed to external like any sane normal or any moderately intelligent person would engineer.

Because of this, they require a VERY specific grade of oil, usually 0w-20 or 5w-20 full synthetic. If the wrong oil is used the belt will start to degrade and shred itself, this then starts plugging the oil pump pickup with rubber debris and starves the engine for oil. Or it just outright shreds and snaps, like yours did.

The newer Ford EcoBoost engines are notorious for their wet timing belts failing and clogging the oil pickup, thus killing the engine.

About 67k on the clock, 17 plate. Engine blew on a dual carriageway. Took it to a proper, full-fat Ford Dealer and Repairer to have a look and turns out, bad belt. They tried to replace the engine but they couldn't work out how to fit it, nor code it correctly. Ridiculous. Always had Fords, but this entire experience put us off them completely.

I have a lease 2020 transit, put it in for a new timing belt at 96k miles, drove a further 500miles after belt change and engine blew, found fault to be a bolt snapped on belt pulley, engine now scrap!\nThis van has full ford service history at every interval, and top-up oil was correct Castrol grade used everytime, garage told me they have three other vans in with same fault!
