Factory MOPAR/Jeep ones are best, so I have heard.

 

Here she sits...



I have one bolt welded to the flexplate , that needs to be removed, then I can disconnect the transmission and yank her out.

 

Upgrading to the 99+ intake manifold and power steering pump... What's the right way to route the belt? Do I remove the old idler pulley?

 

This engine swap is getting really old. We should/could have been done over the weekend. But, that didn't happen. Then we were supposed to do it all last night. That didn't happen. We did finally take the motor out last night. Thank gawd I snagged a new flex plate and bolts. The old ones bolts were tac welded in place. I finally managed to break them loose and found a circumferential crack around the flex to crank bolts. Anyway, hopefully we can get the other motor put in tonight.

 

So, here's the old flex plate. Nice crack aye?




And here's as far as we have gotten...

 

Nice. You almost make me want to tear into mine. Almost.

 

Due to the cracked flex plate, loose flexplate bolts and welded flex plate bolt, I may have a perfectly good spare motor, after all. My only concern is a few spots on the block, head and freeze plug, looks to have some kind of plug in them... Like its filled with silicone and has a metal tag stamped in to it. The metal tag saysGAURANTEE ..... DO NOT REMOVE. I know the original motor, when I bought the jeep, was from a junkyard.

 

Those aren't plugs. They're temperature-sensitive discs so the salvage yard can tell if the motor or head was overheated so they'll know if they should honor the warranty or not.

 

So it's nothing I should worry about if I were to rebuild it for aback up?

 

Not at all. I'm sure it's well outta the salvage yard's warranty period, and you're just using it for a rebuildable core, anyway. You can scrape 'em off if you want.

 

The salvage yard engine would have been warranted to the original purchaser only. Probably for 90 days-6 months or so.

 

Now, all that's left is wire starter, connect battery, install alternator, wrap belt, attach downpipe and o2 sensor, install fuel injectors and rail, install air box, install radiator, fans and fluid... Then attach everything forward of the radiator and hope and pray she starts. On the initial start up, should I be expecting a high idle for a bit?

 

My junkyard motor idled within 10 seconds after startup.

 

Before we install the radiator, we wanted to do a test fire. I turn the key, now fuel is going everywhere, from the fuel pressure regulator; didn't leak before, but it sure does now... Strange! One thing after another, I tell us'... Haha. Hopefully today tells a happy ending story.

 

Test fire.... Success!
