Are the big end bearings on the 1HD-T just like the head on the 2LT-E...that is they are just waiting to fail? And is there anything that can be done to prolong their life such as different oils or more frequent oil changes?
what are the BEB like in a 3b?
when should they be replaced in a 3b?
any one know im just curious?
3Bs don't have the bearing problem. It's generally rings (low compression)that result in a rebuild being required between 400,000 and a million km. You do bearings because you're in there not because they really need to be replaced.
