PLEASE HELP - 1997 LX450 208k Miles - MAGNETIC METAL IN OIL

[Fj80oregon]

I replaced the 2 rear most main bearings in situ late last year on my daughters LX450.

Dropped both pans, loosened all main caps a wee bit and pushed the old bearing out with the new bearing. I have a 2 post lift which made it a bit easier.

I did find out the "different size" main and rod bearings are a thing of the past. Standard or regrind sizes only.

The project ended up a failure as the #5 rod journal was a bit undersized from damage and knocks even with 20W50 oil.

If I had to do it over again I would have sourced a good used engine and gone to town.

What do you mean different size bearings are a thing of the past?
