The DC2 Integra Type R is one of Honda's finest high-revving naturally aspirated platforms, but 25+ years and hard driving have taken their toll. The B18C5 engine is bulletproof when maintained, but neglect kills valve trains and oil-starved bearings; the cable-actuated transmissions hold up well but mounts fail constantly.
Worn Valve Train Components (Lifters/Rocker Arms)
Common · high severityTypical onset: 100,000-150,000 mi
Symptoms: ticking/tapping noise at idle that increases with RPM, noise persists after engine warmup, VTEC engagement becomes noticeably rougher or delayed, eventually throws check engine light for cam position correlation
Fix: Requires valve cover removal, rocker arm shaft assembly disassembly, and replacement of worn lifters and rocker arms. Count on 6-8 hours labor for thorough job including valve lash adjustment. Many shops will recommend doing camshaft inspection and timing belt service simultaneously since you're already in there. OEM Honda parts are mandatory—aftermarket lifters fail quickly.
Estimated cost: $1,200-2,000
Collapsed Transmission Mounts
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: harsh clunking when shifting from reverse to drive, excessive drivetrain movement visible when revving in park, vibration through shifter and cabin at idle, difficulty getting into gear cleanly
Fix: Front and rear transmission mounts typically fail together on hard-driven cars. Front mount is straightforward, rear requires transmission support. 2-3 hours labor total. Upgraded polyurethane mounts add NVH but last longer—OEM rubber on a 1997 will fail again in 40-50k miles.
Estimated cost: $400-700
Oil Starvation and Spun Rod Bearings
Occasional · high severityTypical onset: 120,000+ mi
Symptoms: low oil pressure light flickers during hard cornering or high-RPM runs, metallic knocking from bottom end that increases with RPM, sudden loss of oil pressure accompanied by catastrophic engine noise, metal shavings in oil or on magnetic drain plug
Fix: These engines rely on 0W-20 or 5W-30 oil and frequent changes—neglect or using thicker oil kills bearings. High G-force cornering on track starves oil pickup. Once bearings spin, you're looking at bottom-end rebuild or replacement shortblock. Full teardown, machine work, new bearings, rings, gaskets: 25-35 hours labor depending on damage extent. Many owners opt for used JDM B18C replacement engines at 12-15 hours swap time.
Estimated cost: $3,500-6,500
Head Gasket Failure
Occasional · high severityTypical onset: 90,000-130,000 mi
Symptoms: white smoke from exhaust on cold start, coolant loss with no visible leaks, milky appearance to oil on dipstick or in valve cover, overheating under load or sustained high RPM, bubbles in coolant reservoir when running
Fix: Often caused by overheating from neglected cooling system or sustained high-RPM abuse. Requires cylinder head removal, resurfacing (common on these thin-deck B-series heads), new head gasket and head bolts, timing belt replacement while apart. 12-16 hours labor including machine shop time. Always check head for cracks and warpage—if warpage exceeds 0.002 inches, resurfacing is mandatory.
Estimated cost: $2,000-3,200
Failed Harmonic Balancer (Crankshaft Pulley)
Occasional · medium severityTypical onset: 80,000-120,000 mi
Symptoms: visible wobble in crankshaft pulley at idle, squealing belt noise that changes with engine speed, rough idle and increased vibration through chassis, check engine light for crank position sensor codes
Fix: Rubber damper layer separates from hub, causing pulley wobble that throws off accessory belt alignment and crank sensor readings. Requires pulley puller tool and reinstallation to proper torque spec (181 ft-lbs). Good time to do timing belt if it's due. 2-3 hours labor, OEM Honda part required—aftermarket fails quickly.
Estimated cost: $350-600
Worn Synchros (2nd and 3rd Gear)
Common · medium severityTypical onset: 100,000+ mi
Symptoms: grinding or crunching when shifting into 2nd gear under aggressive driving, difficulty engaging 3rd gear when cold, gear pop-out under deceleration in 2nd or 3rd, need to double-clutch to get clean shifts
Fix: Cable-actuated S80 transmission is strong but hard shifting kills synchros. Requires transmission removal, disassembly, synchro ring replacement. 8-12 hours labor. Smart shops replace all synchros and inspect shift forks while apart since you're paying the labor anyway. Honda MTF fluid helps but won't fix worn synchros.
Estimated cost: $1,800-2,800
Leaking Cam Seal and Valve Cover Gasket
Common · low severityTypical onset: 70,000+ mi
Symptoms: oil seepage visible around valve cover perimeter, burning oil smell from engine bay after hard driving, oil drips on exhaust manifold causing smoke, low oil level between changes
Fix: High-revving VTEC engines work gaskets hard. Valve cover gasket, spark plug tube seals, and cam seal all leak eventually. Simple job: 2-3 hours labor including cleanup. Do timing belt side cam seal during timing belt service. Use OEM Honda gaskets—aftermarket cork gaskets leak immediately.
Estimated cost: $300-500
Absolutely buy one if you find a stock example with complete records and no crash history—just budget $2,000-3,000 immediately for deferred maintenance on any 100k+ mile car.
