This forum has been an incredible resource. So with this beater now in my garage for past month and a half I figure it's time to start posting progress updates. I bought the truck as a project and have a steep learning curve ahead. I've already started a "4ZE1 tune up priorities" help request thread so I'll just pick up where I've off there.

I started out by trying to identify the source of the known fuel leak that the PO said, "happens after the truck sits a couple of days." It didn't leak when I test drove but dumped quite the puddle after it sat in my garage for 2.5 weeks. With help here the plan was to replace all fuel hoses and injector seals. More digging around and Shaggy's thread pointed me to Jim's Injector repair service. I'm glad I did! Jim let me know last night that one injector was bad. I'm replacing it and another reman injector (I believe/hope the source of the leak) with OEM remans from Car-ID.

I got the injectors on their way to Jim on 12/16. Jim will be sending them back to me today or tomorrow. I'm waiting to dig into anything else in the engine until I can start the truck again without a fuel leak. So the past couple weeks I've been focusing on the interior, collecting parts, learning about wiring, gauges, etc. Here's where I'm today on 1/1/21.

Finally got the truck back on the road! Last November it started burning oil into huge clouds that filled up the neighborhood. Got the head rebuilt but the problem persisted. Got the motor rebuilt by CBA in Chandler, AZ a couple of months ago and finally got it all back together and installed last week.
