honestly im new to mechanical terms, still learning in college. i dont know what a blow by is, i think its related to high pressure tho. and yeah im thinking of rebuilding the 2.5, and no i wont be looking for a 4.0, cause im gonna drop in a 5.9 in the future, why have to do 2 engine swaps?
the 2.5 is an okay engine, gets me where i need to go and pulls just fine for the truck, hell i pulled robins fishing boat with it
the entire truck needs to be worked on i know that, which is why i bought it ;D
