Disadvantages of the ESG engine
Not everyone will be able to handle this engine’s high fuel consumption, despite its extreme dependability.
Hydraulic lifters and MDS systems require 5W-20 type oil.
The EGR valve becomes dirty and sticks easily when low-quality fuel is used;
Furthermore, the studs holding the exhaust manifold in place could burst, and it might lead here. Hemi ticking is a term used to describe strange noises that are often heard underneath the hood.
