The problem this solves
Engine bays collect a baked-on film of oil mist, road dust, and grease — especially around the valve cover, intake manifold, and the back side of the radiator. Hand-cleaning is hours of work with rags and degreaser. Pressure-washing risks soaking the harness, the alternator, and the ignition system.
On a restoration project, the additional problem is preservation — original engine paint, factory inspection markings, vacuum-line routing tags, and decals all need to survive the cleaning.
Why dry ice blasting fits
Dry ice pellets are non-conductive and dry. We can blast within inches of live electrical without the moisture risk that comes with water-based methods. The harness, the sensors, and the ignition all stay dry.
On baked-on oil film, the thermal shock embrittles the contaminant layer; it flakes off the block, the intake, and the firewall cleanly. Factory paint and inspection markings survive at the right pressure setting.
Surfaces and equipment we clean
- Engine block, valve covers, intake manifold
- Firewall and inner fender wells
- Alternator, AC compressor, power steering housings
- Harness routing and connector blocks (with care)
- Underside of hood and hood insulation perimeter
- Radiator support and core support
Where this isn't the right method
- Running engines — work is done cold, ignition off, key out.
- Open intake manifolds — keep the intake sealed during the blast pass.
How the engagement runs
- 01Cool down + masking
Engine fully cool. We mask the intake, exposed connectors, and any sensitive sensors per the customer's spec.
- 02Blast pass with low-pressure first
Test on a hidden area, then work zone by zone.
- 03Wipe-down + photo handoff
Loose debris swept; before/after photos delivered.
- 04Optional: chassis combo
Most customers bundle engine bay + chassis for restoration work.
What drives the quote
- Engine size and bay complexity
- Buildup severity
- Preservation requirements (factory finishes intact vs. detail-only)
- Whether the chassis is in the same visit
What we bring, what we coordinate
- Ignition off, key out, battery disconnect for full-bay work.
- Intake openings sealed.
- CO₂ monitoring in enclosed shop bays.
Engine Bay Cleaning — questions buyers ask us
Yes. Most daily-driver bays are a 60–90 minute job depending on buildup. We don't disassemble; everything stays installed.
Not at the preservation pressure setting we use for restoration projects. If you want them removed, we can dial it up — tell us up front.
No. We mobilize to your shop or driveway. Need a flat, accessible workspace and 30 amp/220v if we're running the on-board compressor inside.
