Porsche Engine Repair in Vantaa
Every sound matters — and we know them all.
Porsche engines demand precision: M96/M97 flat-sixes, 9A1 DFI, Cayenne V8s and PDK dual-clutch gearboxes. We know IMS bearings, AOS separators and cylinder scoring — we fix the root cause, not the symptom.

Porsche — known engine faults we repair
Every brand has weak spots. These are the Porsche faults we know best — diagnosed, documented and repaired with OE-quality parts.
IMS bearing failure on M96/M97
Symptom
Metal shavings in the oil filter, vague hum at idle — at worst, total engine failure without warning.
Our fix
We replace the IMS bearing with the updated LN Engineering unit. Recommended preventively on M96/M97 engines before 150,000 km.
AOS (air-oil separator) failure
Symptom
Bluish smoke from the exhaust under acceleration, oil in the airbox, increased oil consumption.
Our fix
We replace the AOS with an OE unit and inspect the intake gaskets, cleaning as needed — prevents costlier downstream faults.
Cylinder scoring on 9A1 3.4/3.8 DFI
Symptom
Knocking noise from cold start, compression loss, sharp rise in oil consumption.
Our fix
We diagnose with a borescope and compression test. Mild scoring is corrected with Nikasil resurfacing; serious cases need cylinder replacement or a block rebuild.
Rear main seal leak on M96
Symptom
Oil drops where gearbox meets engine, dropping oil level with no visible upper leaks.
Our fix
We replace the RMS seal and inspect the IMS bearing at the same time — two jobs in one saves significantly.

Diagnostics
How we diagnose Porsche engine faults
First we isolate the root cause, then we choose the repair. That avoids unnecessary parts and makes the estimate reliable.
Brand-specific fault-code and live-data check
We start with diagnostics matched to M96/M97 3.4/3.6/3.8 boxer, 9A1 3.4/3.8 DFI, M48 4.5/4.8 V8, MA1 3.0/3.6 boxer engines. Fault codes and live data are compared against the symptom so we separate an electrical issue from mechanical damage before ordering parts.
Compression, leak-down and pressure tests
If the symptom points to a fault such as ims bearing failure on m96/m97, we measure compression, leak-down and coolant or boost pressure. That confirms whether the fault is in the head, timing system, piston rings or an ancillary component.
Endoscope and visual inspection
When needed, we inspect the cylinders with an endoscope, check leaks, carbon build-up and crankcase ventilation, then document the findings before you approve the repair.
Repair scope
Porsche engine repair from small faults to full rebuilds
Timing system and valve-train repairs
We repair faults such as aos (air-oil separator) failure by replacing chains, belts, tensioners, guides and required seals as one controlled package.
Oil consumption, smoke and compression repairs
When the fault is in piston rings, valve-stem seals or the head gasket, the repair follows the root cause. We do not mask symptoms with additives; worn parts are repaired or renewed.
Ancillaries, turbochargers and emissions systems
We also diagnose faults such as cylinder scoring on 9a1 3.4/3.8 dfi, EGR, DPF, water pump, turbo and fuel-system issues before recommending an unnecessarily large engine repair.
Repair or replacement engine
Repair is often safer than an unknown replacement engine
A repaired engine is known inside out
A used replacement engine can carry the same model-specific fault as the failed one. In a repair, wear parts, seals and risk points are inspected and documented.
Lower risk when the damage is scoped correctly
After diagnosis we compare repair, partial repair and replacement-engine costs. If an engine swap is the better route, we say so directly.
Warranty on labour and installed parts
The repair uses OE-quality parts and a written estimate. You get a clear repair scope, not just an unknown used component.
Price and scope
Porsche engine repair pricing depends on diagnosis
The starting price is a baseline, not a guess
A full engine rebuild starts from EUR 1,999 on common four-cylinder engines. The final price depends on engine code, damage scope and parts availability.
Individual jobs are priced separately
If a full rebuild is not needed, the cards below show typical engine jobs such as timing belt, head gasket, EGR, turbo and water pump work.
Work starts only after approval
After diagnosis you receive a written estimate. We start only once scope, price and schedule are clear to you.

FAQ
Porsche engine repair — frequently asked
Is preventive IMS bearing replacement really necessary?
For 1997–2008 M96/M97 engines — absolutely yes. A bearing failure destroys the whole engine. The updated LN Engineering bearing is far more durable than the original.
How often should Porsche engine oil be changed?
We recommend every 10,000 km or annually — shorter than the manufacturer's 20,000 km interval. Quality oil protects the engine, especially on drives dominated by low-rpm city running.
Can you repair our Porsche's PDK gearbox or does it need the main dealer?
We handle PDK oil changes, mechatronic repairs and most fault codes. Only rare internal damage requires opening the gearbox.
