The 2022 718 Spyder with the 4.0L flat-six is among Porsche's most reliable modern sports cars, but early IMS-style concerns have been replaced by bore scoring risks on high-revving examples and typical flat-six oil consumption quirks that demand vigilant monitoring.
Bore Scoring / Cylinder Wall Wear
Rare · high severity
Typical onset: 40,000-80,000 mi
Symptoms: Excessive oil consumption beyond 1 qt per 1,000 mi, Cold-start smoke or blue exhaust under load, Metallic debris in oil analysis, Loss of compression in one or more cylinders
Fix: Full engine rebuild or short block replacement required. Expect 30-40 labor hours for teardown, machine work or new block, reassembly. This is the catastrophic failure that kills these motors when oil starvation or aggressive cold starts accelerate wear.
Estimated cost: $18,000-28,000
Transmission Oil Cooler Leaks
Occasional · medium severity
Typical onset: 30,000-60,000 mi
Symptoms: Transmission fluid pooling under car center-front, Burnt fluid smell after spirited driving, Low trans fluid warnings on dash, Cooler line seepage at crimp fittings
Fix: Replace oil cooler assembly and lines. 4-6 hours labor including fluid flush. PDK coolers prone to crimp failures at hard-line connections, especially on track-driven cars.
Estimated cost: $1,200-2,000
Transmission Mount Failure
Occasional · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Clunking on hard shifts or throttle lift, Vibration at idle in gear, Excessive drivetrain movement visible from below, Harsh engagement into reverse
Fix: Replace rear transmission mount. 2-3 hours labor. The rubber isolator tears from repeated launch control use or track abuse. OEM mount is the only option that lasts.
Estimated cost: $600-1,000
High Oil Consumption (Normal Characteristic)
Common · low severity
Symptoms: 1 quart consumed per 1,500-2,500 miles during break-in, Stabilizes to 1 qt per 2,000-3,000 mi after 10,000 mi, Increased consumption during track days or extended high-RPM use, Low oil light between service intervals
Fix: This is normal for the 4.0L flat-six with dry-sump oiling. No fix required unless consumption exceeds 1 qt per 1,000 mi after break-in, then suspect bore scoring. Monitor oil level every 500 miles religiously.
Fuel Filter Clogging (Ethanol-Related)
Occasional · medium severity
Typical onset: 20,000-50,000 mi
Symptoms: Hesitation or stumble under hard acceleration, Limp mode activation during WOT pulls, Fuel pressure fault codes (P0087, P0088), Rough idle after sitting for weeks
Fix: Replace in-tank fuel filter and pump assembly. 3-4 hours labor requiring fuel tank drop. E10 fuel degrades quickly in cars driven infrequently; compounds varnish in filter media.
Estimated cost: $800-1,400
Head Gasket Seepage (Track Cars)
Rare · medium severity
Typical onset: 30,000-70,000 mi
Symptoms: External oil weep at cylinder head-to-case junction, Persistent oil smell after heat cycles, Slight oil consumption increase, Visible oil residue on lower engine surfaces
Fix: Replace both head gaskets and resurface mating surfaces. 16-20 hours labor for engine removal, disassembly, and reinstallation. Mostly seen on cars with repeated heat-soak from track use or aggressive mountain driving.
Estimated cost: $6,500-9,500
Owner tips
Check oil level every 500 miles without fail — the dipstick is your best diagnostic tool for catching bore scoring early
Use Mobil 1 0W-40 or approved equivalent; cheap oil accelerates cylinder wear in high-revving flat-sixes
Let engine warm to 180°F coolant temp before exceeding 4,000 RPM to prevent bore glazing
Compression and leak-down test at pre-purchase is non-negotiable — costs $300 but saves $20k
Track-driven cars should get transmission fluid changed every 15,000 miles, not Porsche's 60k interval
Buy one if the PPI shows strong compression and oil analysis is clean — the 4.0L is exceptional when maintained, but catastrophic when neglected, so documentation matters more than mileage.
