The 2022 718 Cayman is largely reliable in its first 50k miles, but the 2.0L turbo four (base model) has documented cylinder scoring issues that can appear shockingly early. The 2.7L flat-six in the S/GTS is mechanically more robust but shares some oiling concerns under track use.
2.0L Turbo Cylinder Scoring / Bore Wear
Occasional · high severityTypical onset: 20,000-60,000 mi
Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Cold-start smoke from exhaust (blue-ish tint), Loss of compression on cylinders 2 or 4, Metallic rattling at idle once advanced
Fix: Requires full engine rebuild or short block replacement. Pistons, rings, cylinder liners, sometimes crank polishing if debris circulated. 25-35 hours labor depending on teardown extent and machine shop work.
Estimated cost: $12,000-18,000
Transmission Oil Cooler Line Leaks
Common · medium severitySymptoms: Small puddle of red/pink ATF under center of car, Transmission overheat warning on track or spirited drives, Low fluid level on dipstick (PDK models)
Fix: Oil cooler lines run along tunnel and are prone to chafing or stone damage. Lines themselves are not expensive but labor is 4-6 hours due to access—must drop undertray, exhaust sections, sometimes subframe for clean routing. Refill and bleed PDK system afterward.
Estimated cost: $800-1,400
PDK Transmission Mounts Deterioration
Common · low severityTypical onset: 40,000-70,000 mi
Symptoms: Clunk when shifting from reverse to drive, Vibration through cabin at idle in gear, Excessive drivetrain movement visible on hard launches
Fix: Upper and lower transmission mounts crack or separate. Porsche revised mounts once already; use latest part numbers. 3-4 hours labor, requires lift and some underbody disassembly.
Estimated cost: $700-1,100
Fuel Filter Clogging (Both Engines)
Occasional · medium severityTypical onset: 30,000-50,000 mi
Symptoms: Hesitation or stumble under wide-open throttle above 5,000 RPM, Lean fuel trim codes (P0171/P0174), Rough idle after hot soak, Stalling on deceleration
Fix: In-tank fuel filter on these models can clog prematurely, especially with lower-quality fuel. Requires fuel tank drop, 5-6 hours labor. Porsche recommends replacement only at 60k mi, but real-world fouling happens earlier.
Estimated cost: $900-1,300
Connecting Rod Bearing Wear (2.7L Flat-Six, Track Use)
Rare · high severitySymptoms: Metallic knocking from engine bay under load, especially hot, Low oil pressure at idle when fully warmed, Metal flakes in oil filter or drain plug magnet
Fix: Hard track driving or missed oil changes can accelerate bearing wear. Requires engine-out, case split, bearing inspection, and crank polishing/replacement. 30-40 hours labor if crank needs grinding. Often discovered during proactive inspection by track drivers.
Estimated cost: $10,000-16,000
Head Gasket Seepage (2.0L Turbo)
Occasional · low severityTypical onset: 50,000-80,000 mi
Symptoms: Slight coolant smell from engine bay, Minor oil weeping at cylinder head mating surface, Coolant level drops slowly (not catastrophic leak), No overheating, no mixing of fluids
Fix: The 2.0T can develop minor head gasket seepage at high mileage. Not an emergency but requires engine-out service to replace head gaskets properly. 18-22 hours labor. Often done alongside IMS or other preventive work.
Estimated cost: $4,500-6,500
The 2.7L S/GTS models are solid buys used; avoid 2.0L turbos unless you have documentation of a clean borescope and low oil consumption—cylinder scoring is the career-ender here.
