You've inspired me. I am 62, not retired (I do not have permission from my wife yet). I have all the requisite tools, less taller jack stands but I can make something tall and stable enough. My current motor has 171+k miles on it, so it probably is tired. I don't want to let go of this car, so I might give it a whirl. There is more than likely enough folks here that can bail me out via this forum if I find my self in trouble. I became one with my 912 the first time I did a complete rebuild on its motor, so why not have the same experience with this one. Thanks for the encouragement. I'm going for it. BTW where did you source your engine from?

Before tracking down a replacement engine, are you sure your current motor is really toast? There have been plenty of instances where the mechanic said to replace when all that was needed was an AOS. Think I'd be absolutely, positively sure before dropping a bunch of money on something you might not need.
2nd, if you do need to replace the motor, the Bentley manual has plenty of info on how to remove / replace an engine.
3rd, is there a back story to your current engine? Were there issues when you replaced your IMS, like possible metal shavings floating around? I don't have the best memory anymore, but seem to recall something like this with a member a few yrs back. Would be good info for the community.

Good sentiment. But his engine does have 171k miles or so--which is like 500,000 in Toyota miles. Or 250,000 in 96 Dodge Dakota miles. Probably past it's pull date.

Guess I missed that leading 1.

911, 911, 911,911 motor
How inspired can you get?
You did pretty well at 170k+ miles. And it may not be a toasted motor but something that could be fixed
But spending $$$ on a 18-19 year old 170k+ mile motor doesn't make much sense either
So it just hit me , you replaced the IMSB at 161k miles. How much did that cost?
At what point mileage wise(110k, 120k) is it just not worth replacing the bearing. I would think at 161k it's not worth disturbing it especially since it is a dual row bearing
If it was my car I would want to know it wasn't the replacement IMSB after 10k miles

Regarding the IMS replacement, I had it done at 163K miles while the clutch was being replaced. Did not have a thorough history of the car so I took the safe route.

Good! I did mine completely by myself, btw, no one helped me.
Here's the source of my engine. My experience with him (so far) is that he's pretty much on the up & up. I got a used top (w/ frame) from him, too. I picked mine up at the Fedex LTL dock so it was pretty reasonable shipping.

BTW, the air jack & the tall jackstands (6 ton) are available at Harbor Freight and are definitely worth having.

He's done right by me.
Did you find anything about your old engine? A blasted AOS wouldn't provide enough oil to hydrolock the engine while it was running down the road--and there would be a huge cloud of smoke out the tail pipe.
