I'm replacing my motor in my truck 420 000 miles never been apart never had injectors. Uses oil now blowby 1 gallon in 2000 miles but has good power and fuel economy. I'm going with a reman with 18 month unlimited mileage warranty and new injectors from diesel logic 2 year unlimited mileage warranty. Any thoughts or experiences with this company. Ebngine is long block from South Houston engines.
