Well, I'm baffled and relieved (sorta) at the same time. I picked my 80 from the stealership this morning, with a dreary breakdown of what was wrong in their opinion, written on an official Toyota form: injectors good for s****, HG blown and cylinder heads possibly eaten alive. To spice it up, compressions were also in the basement according to them. The service manager tells me I'd better "recycle" the rig. Remember, at first, I wanted them to fix a code 26 and a rough idle so I could smog it and renew my registration. No way with such a ****py motor they say.
Anyway. I give the Cruiser later this morning to a local mechanic for what I expect to be an open heart surgery as you fellow Mudders have convinced me I had jumped the gun by declaring the rig DOA and good for the junkyard. I expect him to charge me a couple grand for an HG job.
Tonight, phone call: the rig isn't only running flawlessly with its original HG, but it passed the smog inspection with flying colors! It gets better: the mechanic is positive nobody had checked the compressions in a long time on that truck. Indeed the compressions are excellent for a 127 k engine he states.
I'm now puzzled about Toyota's behavior and assessment: didn't they want to tackle anything on a 14 yo rig and make up the list to scare me off, did they simply rip me off, or are they utterly useless? I have another Toyota (DD) that I used to service there but they have lost my business for good.
Now, of course, the HG might still have a problem looming but the rig hadn't been drinking coolant nor overheating at all prior to last day's events. And last time I wheeled it seriously was at Joshua Tree in July, a/c at full power, 105 F outside. It worked great and didn't show any trouble.
So I will be keeping an eye on the coolant level, temperature indicator and exhaust fumes color in the next months, more carefully that I would normally have, that's all.
As for Toyota, I won't file a complaint, but I will shoot an e-mail to the manager, letting him know that my "recyclable" rig runs like a charm with a valid smog inspection certificate.
So it's a happy ending so far. Thanks all for helping me tackle the situation.
