Anyone have any experience with Cat 3126 diesel engine . This one has 150,000 miles in a 1998 .I have heard good and very bad about this engine. Should I run away ?
The 3126 engine is a very good engine. When new they had a 500 thousand mile or five year warranty. If properly maintained, this engine will last you a long time. The 3126-B has a deep oil pan and holds a lot more oil then the shallow pan on the 3126-E or the C-7 which all have the same block.
Lot of RVer's claim that these engines can not be sleeved, but that is not true. There are kits for installing sleeves if so desired.
