Duramax | Deer Park Diesel

6.6L

The 6.6L Duramax engine was introduced in GM pickups in 2001, in it’s first iteration- the LB7 engine. Since then, we have seen the LLY, LBZ, LMM, LML, and now the L5P. These engines are all built on the same basic block design, but have significant differences pretty much everywhere else. 


Common repairs include:

  • Fuel injectors
  • Water pump
  • Turbocharger replacement
  • Glow plugs
  • Emissions system failures (LML and newer)


We offer full services on all 6.6L Duramax engines.

Emissions Modifications

We do not modify or tamper with emissions components of any kind, for any reason, in such a way that would violate or prohibit the originially intended use and function.

Custom Tuning

We do not sell, install, or provide custom tuning/programming.

OEM Flash/Reprogramming

We do not flash or reprogram vehicle modules at this time. All re-flash or programming must be referred to a dealer.

Transmission Rebuilding

We do not rebuild automatic or manual transmissions; we perform the R&R, and sublet the rebuild to another supplier. We will perform transmission services and limited diagnostics, but will not perform repairs that go beyond the valve body. 

Engine Rebuilding

We do not rebuild engines. We will perform R&R, and purchase remanufactured long block and running complete engines from suppliers that offer a warranty. 

Body/Glass

We do not perform any auto body repairs or glass work. We will replace handles, mirrors, lights, etc and internal components such as switches, locks, etc

Fabrication

We do not provide custom fabrication services unless they are required to complete a repair that we otherwise would provide; this must be handled on a case-by-case basis and is billed by time and materials.
