1967 Chevrolet Camaro Problems: 7 Known Issues

On the 1967-1969 Chevrolet Camaro, the cowl plenum under the vent grille collects leaves and debris, and its drains plug; trapped water then rots the cowl from the inside out and rots the lower corners where the cowl meets the A-pillar and the firewall. The rain-gutter and A-pillar seams are sealed only with seam sealer that cracks with age, letting moisture in behind the A-pillar post. The corner where the hood meets the cowl is a known rot point, made worse when the hood-to-cowl seal is missing so rain and debris hit the outer firewall directly. Because the rot starts inside the double-walled cowl, it is often advanced before it shows, and water leaks into the footwells are an early warning.

On the 1967-1969 Chevrolet Camaro, first-gen Camaros were never dipped in a chemical rust-proofing tank before paint at the factory, so the unibody corrodes badly when neglected or driven in salt. The classic rot spots all stem from trapped water: the rear-window channel has no proper drain so water pools under the glass and rots the lower window lip and package tray; that water then runs straight into the trunk and eats the trunk pan and drop-offs; and the rear quarters rust in front of and behind the tire where the factory lapped two panels together in the wheelhouse, trapping dirt and tire-thrown water between them. Visible holes typically represent only about 10% of the actual rust, so adjoining floor pans, frame rails and the package tray are usually involved too.

On the 1967-1969 Chevrolet Camaro, the vast majority of first-gen Camaros left the factory with four-wheel drum brakes that fade badly with repeated or hard stops, pull when the shoes glaze, and feel wooden — dangerously under-braked for the V8 power many of these cars make, especially after upgrades. The optional front discs (RPO J52) used a four-piston caliper on 1967-68 cars and a single-piston caliper for 1969. 50-year-old drum hardware (wheel cylinders, springs, self-adjusters) is usually seized or leaking on a restoration candidate.

On the 1967-1968 Chevrolet Camaro, early first-gen Camaros used a single mono-leaf rear spring that lacks the rate to control V8 torque. Under hard acceleration the spring wraps into an S-shape (spring wrap), the axle rotates, the tire momentarily lifts and unloads, then the spring snaps back — the classic, violent and unsafe wheel hop that can break U-joints, axles and spring eyes. Early 1967 cars also located both rear shocks ahead of the axle on the same arc, which did nothing to damp the hop. Chevrolet's mid-1967 band-aid (a radius/traction bar) and the 1968 switch to staggered shocks plus optional multi-leaf springs reduced it, but mono-leaf V8 cars remain notorious for it.

On the 1967-1969 Chevrolet Camaro, the tight first-gen engine bay leaves little room for radiator and fan, and the original copper/brass core struggles to shed the heat of a 396 big-block (and a hot 350) in stop-and-go traffic, at idle, or with A/C. Decades of scale and a tired clutch fan or a missing/incorrect fan shroud make it worse, so these cars routinely creep toward the top of the gauge in summer traffic — a real concern for a freshly rebuilt engine.

On the 1967-1969 Chevrolet Camaro, the factory breaker-point distributor needs constant maintenance: points pit and close up, dwell and timing drift, and a 50-plus-year-old distributor usually has worn shaft bushings that let the timing 'walk,' causing hard starting, stumble and inconsistent idle. Compounding it, the factory runs a resistance wire that feeds the coil only ~9-10 volts, so spark energy is weak — fine for a stock low-compression engine but marginal for any cam/compression upgrade a restorer adds.

On the 1967-1969 Chevrolet Camaro, even when new the first-gen Camaro's slow-ratio recirculating-ball steering box felt vague by modern standards; after 50-plus years of wear the box and linkage develop noticeable on-center slop, so the driver saws at the wheel to track straight. Worn box internals, a worn Pitman/idler arm and tired rag joint all stack up — a safety and drivability weak point that a fresh suspension rebuild alone won't cure if the box is worn out.
