RALZAOTO Oil Catch Can for Chevy Silverado / GMC Sierra 1500 2014-2018 — 5.3L & 6.2L Direct-Fit Anodized Aluminum Kit

RALZAOTO oil catch can is a bolt-on oil-air separator designed to trap crankcase oil vapor before it re-enters the intake on compatible GM V8/V6 engines.

This compact anodized-aluminum oil catch can kit replaces the factory PCV routing on select Chevy and GMC trucks and SUVs to reduce oil buildup in the intake tract. Engineered for 5.3L and 6.2L GM engines found in Silverado, Sierra, Tahoe, Yukon, Suburban and Escalade models, the unit installs with supplied hoses, brackets and fittings so you can finish most installs in about 30 minutes.

How does the oil separator work and what does it remove?

This catch can uses a fine aluminum mesh inside a sealed housing to condense and capture oil vapor and larger droplets carried by crankcase ventilation. It does not alter engine timing or emissions equipment; it simply intercepts oily vapor before it reaches the intake manifold.

• Fine mesh separates vapor into liquid that collects in the can.
• Sealed outlet returns cleaner air back through PCV routing.
• Removable canister for periodic draining and cleaning.

What materials and components are included in the kit?

The kit is constructed from anodized aluminum to withstand engine-bay temperatures and pressure. RALZAOTO supplies pre-formed hoses, custom mounting brackets and fittings to match factory connection points for a direct-replacement style install.

• Anodized aluminum catch can body and lid for corrosion resistance.
• Internal fine-mesh aluminum filter for vapor separation.
• Vehicle-specific hoses, brackets and fittings for bolt-on installation.

How often should the catch can be checked and maintained?

Inspect the catch can after the first 500–1,000 miles and then at regular service intervals. Frequency depends on driving style and engine condition; high-load and towing applications typically fill the can sooner.

• Check level at 500–1,000 miles initial period.
• Drain and clean the can when liquid reaches the removable sump.
• Reinstall securely and retorque fittings after maintenance.

Who is this for: RALZAOTO's oil catch can is aimed at owners of compatible Chevy, GMC and Cadillac trucks and SUVs who want to reduce oil contamination in the intake tract without altering factory sensors or emissions hardware. It suits DIY installers and professional shops needing a direct-fit oil separator that’s durable, serviceable, and designed for V8/V6 GM engines used in towing, performance or everyday driving.
