Engine trouble is stressful, and the decision about what to do can be expensive. Our job is to find out exactly what's wrong and lay out your options clearly: repair the specific problem, rebuild, or replace the engine. Sometimes the honest answer is that the vehicle isn't worth a big engine repair, and we'll tell you that too.

Signs of engine trouble

  • Knocking, ticking or tapping that's getting worse
  • Oil consumption, blue smoke or oil leaks
  • Coolant loss, white smoke or milky oil (possible head gasket)
  • Low oil pressure warnings
  • Loss of compression, persistent misfires or lack of power
  • Overheating history

What we repair

  • Valve cover, oil pan, intake and timing cover gaskets
  • Front and rear main seals
  • Head gaskets and cylinder head repair
  • Timing belts, chains and guides
  • Oil coolers, water pumps and cooling-related engine damage
  • Internal engine repairs, and full rebuild or replacement engine options

How we approach big engine jobs

  1. Confirm the diagnosis with the right tests, such as compression, leak-down, oil analysis or a borescope look, before recommending major work.
  2. Lay out the options: targeted repair, rebuild, remanufactured or used engine, with the pros, cons and cost of each.
  3. Do the work and stand behind it. Qualifying repairs are covered by the NAPA Peace of Mind warranty.

Gas and diesel engines

We work on gas engines in cars, SUVs and trucks, and on diesel engines including Power Stroke and Cummins. Diesel engine work often involves head gaskets and head studs on the 6.0L Power Stroke, injector and injector cup work, and cooling-related damage. See diesel repair for more.

If you’re in the Oak Grove area Elite Diesel & Auto Works should be your go to for your automotive repair needs. I dropped my truck off with an issue beyond my capabilities and picked up a truck that runs better than it did new. They have great customer service and will keep you in the loop throughout the process. I could not recommend this place more.
