Engine Repair in Twin Falls, ID — S&D Automotive
Engine problems range from a misfiring cylinder to a blown head gasket to a complete engine replacement — and the difference between a manageable repair and a major one is often how quickly it gets diagnosed.

We start with the right tests to understand what's actually wrong, we show you what we're seeing, and we give you a clear picture of your options before any work begins.

Signs Your Engine Needs Attention
Engines give warnings before they fail. These are the signs to take seriously:
Check engine light — especially if accompanied by rough running or loss of power
Oil consumption between changes — burning a quart or more every 1,000 miles warrants investigation
Blue smoke from the exhaust — oil burning in the combustion chamber
White smoke or sweet smell from the exhaust — coolant entering the combustion chamber; possible head gasket
Knocking or ticking from the engine — can indicate low oil pressure, rod bearing wear, or valve train issues
Significant loss of power — engine feels weak, struggles under load, or hesitates under acceleration
Engine overheating — any overheating event can cause head gasket or cylinder head damage
Oil in the coolant or coolant in the oil — milky oil or a chocolate-milkshake appearance in the coolant reservoir
That last one is important. If your oil looks milky or your coolant has a brown, oily layer, stop driving the vehicle immediately. Coolant mixing with oil is a sign of a compromised head gasket, and continuing to drive causes cascading internal damage.
Head Gasket & Water Pump — Often Done Together
The head gasket seals the cylinder head to the engine block, keeping combustion gases, coolant, and oil in their respective chambers. When it fails — usually from overheating or high mileage — coolant can enter the combustion chamber, oil passages can cross-contaminate, or compression can leak between cylinders.
The water pump is driven by the timing belt on many engines. Since accessing either component requires significant disassembly, it often makes sense to service both at the same time. We'll advise you on this when it's relevant to your repair.
Engine Replacement — When It Makes Sense
Not every engine problem is worth repairing in place. If an engine has extensive internal damage, high mileage, or multiple failing systems, a remanufactured engine installation is sometimes the better value. We'll give you an honest side-by-side: what an in-place repair costs, what a remanufactured engine costs, and what the vehicle is realistically worth after each option. You make the call with full information.
Why S&D Automotive for Engine Repair
Engine work requires proper diagnosis before any disassembly. We use compression testing and leak-down testing to confirm what's actually failed before recommending major engine work — that approach protects you from paying for repairs that don't solve the real problem. We've been doing this in Twin Falls since 1990, and we take the time to walk you through what we find before asking for a decision.
All engine repairs at S&D are backed by the NAPA AutoCare 24-month/24,000-mile nationwide warranty. Remanufactured engine installations include manufacturer warranty as well — we'll detail coverage when that option applies.

Engine Repair FAQ
-
It depends on what's failed and the condition of the rest of the engine. A head gasket failure on a well-maintained engine with 80,000 miles is usually worth repairing. The same repair on a high-mileage engine with other issues may not be. We assess the whole picture and give you options, not just one path.
-
It varies enormously by what needs to be done. A valve cover gasket is minor. A head gasket replacement is a significant job. A full engine replacement is larger still. We diagnose first, then give you a written estimate. Call (208) 543-8000 if you want to describe your symptoms and get a general range.
-
Not necessarily. The severity of a knock matters. A light tick at startup that goes away with oil pressure may be a minor issue. A deep, rhythmic knock under load is more serious — typically rod bearing wear, which needs immediate attention. Have it diagnosed now rather than waiting.
-
Yes. We've worked on classic vehicles and can handle older engine designs that differ from modern configurations. Call ahead to discuss your specific vehicle.
