Default Here's what happens to a timing belt when an idler pulley seizes up
Luckily, it's a 91, so the engine was fine, but it really made for a lot of cleaning when I took everything apart. Got the new belt and water pump in, and she runs as good as new. Also replaced the plugs, wires, caps & rotors while I was in there.

I'm assuming this service had never been done before at about 86k miles, but at 26 years old, it was well past due.

Wow, that looks like a mess. Glad it was a 91 to minimize the damage. Great job on the clean up and install. Look like you're on the road again...

A stunning mess. My 1990 silently came to dead stop in a snow storm on I-79 in West Virginia due to a frozen idler pulley that bisected the belt very cleanly. Yours looked like it fought to the bitter end.

Man that looks bad. Just to clarify, car only has 86k and it seized up?

Are 91's non-interference?
If so, when did interference start then? vvti/'98? Just curious...
Glad you got it back on the road!

Yep, 138k KM, so about 86k miles. And interference started in 95 I believe. They bumped the compression up a little bit that year.

Correct, '95 for the LS400 is the start of the Interference engines.

Man, that was a heck of a clean-up job. Looks great! Did you buy a timing belt kit, or just the belt and pump?

I used this kit.

Water pump was Aisin, pullies were Koyo & NSK, tensioner was NTN, belt was Mitsuboshi, so they were all quality Japanese made parts. Everything seemed to be equal to OEM in terms of quality.

Thanks for the info! I got my kit @ timingbeltkit.com. They shipped for free and all the parts were high-quality Japanese made.
