No engine related common issues in the UZ engines but you have a timing belt that needs a $1,500 replacement every 90k miles

I don't disagree that it is expensive, or specifically needs a ton of time, but I've done it and I recall it was about 400-500'sh USD or so at an indy shop. I did that when I fixed the lower gasket oil pan leak, plus parts. I do recall the tech explaining that he used whatever standard software showing that the job takes so many hours. Of course it's more in today's dollars, but still....

Thats way cheaper than I've ever been quoted for it to be done. On my old ES300 I paid my independent $900 to do it and that was 15+ years ago.

That does include the water pump which they always do at the same time.

I could be wrong…that’s just what I recall. It was still more expensive service than most other cars at that time.

The OVS/RMS issues primarily happen on the ls2 variant of the m177. I believe the GLx series uses the ls1.
