Toyota 2tr-fe questions

[Doublehaul]

In a UOA of this engine...what should I be looking at for bearing wear. Iron is from the cylinders and valve train, aluminum from pistons etc...but are the bearings led and copper or what in this application

 

[ka9mnx]

Bearings are lead and copper but a UOA is a poor indicator of bearing wear.

 

[Doublehaul]

Don't some fords have aluminum bearings?

 

[ka9mnx]

Not just Ford's. Aluminum can be part of the bearing content.

I thought most if not all auto manufacturers had done away with lead in bearings and anywhere else ?

I rolled bearings into my bosses jeep about 6 years ago. I could not get lead Babbitt bearings. I could only get aluminum ones.
