Diesel Engine Repair & Maintenance

Diesel engine repairs and maintenance, from diagnosis through overhaul, on most major heavy-duty engine manufacturers.

What to expect

George has been diagnosing diesel engines since before most shops had the software to do it, and that is still what customers come here for — the hard one, the intermittent one, the one another shop has already thrown parts at.

We do repairs and maintenance across most major heavy-duty engine manufacturers, from diagnosis and sensor work through to complete overhauls. Most, not all — if your engine is outside what we can properly support, we would rather say so up front than learn it with your truck in pieces.

Straight Answers

Diesel Engine Repair & Maintenance — common questions

Another shop could not find my problem. Will you take it?

That is the work George is known for. Bring what the other shop told you and any codes they pulled — knowing what has already been ruled out and what parts have already been replaced saves you money on our diagnostic time.

Do you work on my engine make?

We cover most major heavy-duty manufacturers — International, PACCAR, Mack, Isuzu, Detroit, Caterpillar, Cummins, Volvo, Ford, GM and Hino among them. Most, not all. Call with your engine and we will tell you straight whether it is one we can properly support.

Is it worth rebuilding an old engine?

Sometimes, and sometimes it is not. It depends on the condition of the rest of the truck, what the rebuild will cost against what the unit is worth, and how long you plan to keep running it. We will give you the numbers and let you decide — we do not sell repairs customers do not need.

Where We Work

Diesel Engine Repair & Maintenance across East County and San Diego County

The shop is on Riverside Drive in Lakeside, so the tow is short from most of East County — and a short tow is real money on a truck that will not roll. We take work from across San Diego County.
