Services

Three areas.One standard.

The focus is engines and gearboxes. The rest of the workshop runs with the same care. Where a price is shown, you pick your make, model and year next — and see the price for your car. Every other service opens its own page.

Prices

Porsche911 air- and water-cooled, Boxster, Cayman, Cayenne, Panamera and MacanRebuild from 8.500 €

Engine & gearbox

The core of the business: Porsche flat-sixes and their gearboxes up to a full rebuild, timing chains and engine repair on Audi, BMW and Mercedes-Benz too.

Servicing & inspection

Planned appointments for whatever falls due at intervals — from an oil change to servicing on the manufacturer's schedule.

Workshop service

Clutch, suspension and everything else a car needs — for all common marques, not only Porsche.

Method

Six steps to handover

The same route for every unit — an air-cooled flat-six or the gearbox out of a 991.

The engine in detail
  1. Split crankcase of a boxer engine with the crankshaft, connecting rods and twin timing chain drive still in place, standing on the workshop floor.
    01

    Diagnosis

    Fault memory, compression and leak-down tests, borescope inspection of the cylinders, oil and filter checked for wear debris. Only once the picture is clear do we talk about scope and cost.

  2. Top-down view of the crankcase of an air-cooled Porsche 964 flat-six with three cylinders and pistons fitted and the timing chain hanging over the case.
    02

    Removal and strip-down

    Engine and gearbox come out of the car and onto the stand. The strip is complete: crankcase, crank assembly and cylinder heads end up in front of us as cleaned individual parts.

  3. Open crankcase with bolted main bearing caps, new plain bearing shells coated in assembly lube and a fresh bead of sealant along the parting face.
    03

    Measurement

    Crankshaft and connecting rods for size and runout, bearing clearances, cylinder bores, flatness of the mating faces, valve guides and seats. Every figure is written down and compared against the manufacturer's specification.

  4. Opened manual gearbox with the gear set, synchroniser rings, selector forks and shift rails exposed inside the housing.
    04

    Repair and parts

    Bores honed, mating faces skimmed, valve seats recut, plus bearings, piston rings, chains, tensioners and gaskets renewed as complete sets. What goes in is what the measurements call for, not what happens to be on the shelf.

  5. Largely assembled air-cooled six-cylinder boxer engine with its cooling ducting fitted; the intake openings on the cylinder heads are still open.
    05

    Assembly

    Assembly in clean surroundings, every fastener to torque and angle, the clearances checked a second time before anything is closed up. Valve timing is set with the specified locking tools.

  6. Silver Porsche 911 Turbo (991) seen from the rear three-quarter, with raised rear wing, centre-lock wheels and red brake calipers in a bright workshop hall.
    06

    Test run and handover

    Once refitted, oil pressure and leak checks, warm-up and a road test. You receive the documentation of the work and a clear word on the running-in period, including the first oil change.

Fault reported, cause to be found

Describe the fault.
We will tell you what to do.

Rattling on a cold start, swarf in the filter, a crunch going into gear — the more precise the description, the more useful the first assessment.
