Babbitt in the Oil

As much as you drive your pickup it must run pretty good? I'm sure there are tons of As running around with too much wear in the thrust bearing that run fine but leak too much oil, what can you live with?

I am prepared to set a 5 gallon bucket of oil on the fender and set up a drip feed system if necessary to get me to the top of Mt. Baker. :rolleyes: All that oil will help keep the dust down...
 
I'd check the clearances on the mains and rods, See what you have left for shims. If you can get everything back to .0015, especially the rear main, you might stop/slow down the oil leak. Ever do a compression test on it?

I've got the same problem. I'm considering strapping a bucket under the rear main, stopping every 50 miles, and pouring the oil back into the engine. ;)
 
So, when I said there was no end play in the crank earlier, I was wrong. I only pushed on the crank. Today I pushed & pulled and as it turns out the end play is actually something like 0.045 (0.045, NOT 0.0045).

Additionally, I took a closer look that I had previously & noticed something new. Does the picture below mean the rear main bearing is cracked/disintegrating? If that is the case, I assume that means I really should get the engine rebuilt?

Link to very high res version of the picture.
 
Also a picture of the some of the crud on my rag after wiping out the pan a few days ago. The right kind of dull silver to be babbitt?

Thats the thrust surface. You'd have to remove the bearing cap to see the bearing surface. There are some brass inserts folks use when going to inserts, maybe that would work for you?

Yeah, but if the thrust surface is all messed up, I assume that doesn't bode well for the bearing surface (but like you say you don't know for sure until you look.)
