1967 CHEVROLET CAMARO

Symptoms: Sagging front end or misaligned doors, Visible rust perforation in front subframe rails, Cracking paint near firewall-to-floor transitions, Steering wander or vague handling

Fix: Torque boxes and front subframe rails rust from inside out due to poor drainage design. Proper repair requires cutting out affected metal, welding in AMD or Dynacorn replacement panels, plus floor pan patches. Expect 20-30 hours labor if both sides need attention. Half-measures with fiberglass or pop-riveted patches fail within a year.

Estimated cost: $3,500-7,000

Typical onset: 60,000-100,000 mi

Symptoms: Excessive driveline clunk on throttle tip-in, Vibration at idle that worsens with A/C or load, Transmission hitting crossmember on hard acceleration, Visible cracking or separation in rubber mount pads

Fix: Original rubber mounts last 10-15 years maximum; most '67s are on third or fourth set. Collapsed mounts cause driveline angles to shift, accelerating U-joint and tailshaft bushing wear. Replace all three engine mounts and transmission mount as a set. 3-4 hours labor. Polyurethane mounts reduce service life but improve performance feel.

Estimated cost: $400-750

Typical onset: 80,000-120,000 mi

Symptoms: Harsh or delayed 1-2 shift, Transmission slipping under load, White smoke from exhaust (ATF sucked into intake), Transmission dipstick shows low fluid with no visible leaks

Fix: Vacuum modulator diaphragm ruptures, allowing ATF into intake manifold via vacuum line. Replace modulator ($30 part) and check transmission fluid level—if low, internal damage may have occurred from running dry. If fluid is full, it's a 1-hour job. If transmission slips after refill, expect rebuild due to clutch/band damage. Check modulator annually on high-mileage units.

Estimated cost: $80-150 for modulator only; $1,800-2,800 if rebuild needed

Typical onset: 100,000-150,000 mi

Symptoms: Low oil pressure at hot idle (under 10 psi), Metallic knocking that worsens with RPM, Rod knock audible on cold start that quiets slightly when warm, Oil consumption above 1 qt per 500 miles

Fix: High-mileage 283/327/350 engines with unknown maintenance history develop bearing clearance issues, especially if run low on oil or with extended drain intervals. Requires engine removal, full teardown, crank inspection, and bearing replacement. If crank needs grinding, add machine shop time. Budget 18-25 hours for removal, bearing replacement, and reinstall. Confirms the need for documented maintenance history when buying.

Estimated cost: $2,500-4,200

Symptoms: Fuel gauge reads empty or full regardless of level, Hard starting after sitting more than a week, Fuel starvation or stumbling at quarter-tank or below, Visible rust flakes in fuel filter

Fix: Tanks sit for years with stale fuel, creating varnish that clogs pickup sock and corrodes sending unit float arm. Drop tank (2 hours), inspect for rust-through. If solid, clean with hot tank or electrolysis, replace sending unit and hoses. If rusted through, aftermarket replacement tanks run $250-400. In-tank fuel filters help but aren't a substitute for cleaning.

Estimated cost: $400-900

Symptoms: Brake pedal goes to floor with no warning, Complete loss of braking with any hydraulic leak, Fluid weeping from master cylinder rear seal

Fix: 1967 models came with single-circuit master cylinders—any leak means total brake loss. Upgrade to 1968+ dual-circuit master with proportioning valve and distribution block. Requires new brake lines and master cylinder mount modification on some early cars. 4-6 hours including line fabrication and bleeding. This is a mandatory safety upgrade, not optional. Factor this into purchase price if not already done.

Estimated cost: $600-1,200

Symptoms: Water dripping onto passenger feet from HVAC vents, Musty smell from heater, Rust bubbling below windshield corners, Wet carpet that never fully dries

Fix: Leaves and debris clog cowl drains, water backs up into plenum chamber and seeps through firewall seams or rusts floor pans from inside. Clearing drains is 1-hour preventive job; if plenum is rusted, windshield comes out and metal replacement is 12+ hours. Run a coat hanger through cowl drains twice a year. If buying, pull back carpet and check for rust staining.

Estimated cost: $100-200 for drain cleaning; $2,000-3,500 for plenum replacement
