Honda Stream Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Honda Stream replacement engines. Whether addressing widespread D-series VTEC head gasket failures or L-series timing chain wear across all generations, we provide direct OEM-spec solutions for the entire Stream series.
Honda Stream Replacement Engines
The Honda Stream spanned two key generations: the first (RN1-RN5, 2000-2006) with D17 and H22 engines, and the second (RN6-RN9, 2006-2014) featuring L18 and L20 i-VTEC units. Across both generations, shared design traits led to consistent failure patterns: D17A engines suffered from head gasket breaches due to thermal stress in all trims, while L-series variants uniformly experienced premature timing chain tensioner wear. Honda Technical Bulletin 06-042 addressed head gasket sealing on early D17 engines across the RN1-RN5 chassis, and later L18Z1/L20Z1 units inherited oil pump-driven chain tensioner flaws affecting all Stream models regardless of drivetrain or trim.
Honda Stream Models & Engines Codes
Engine families are consistent across trims within each Stream generation, with shared components leading to uniform failure modes:
- D17A1/A2: 1.7L i-VTEC (RN1-RN5, 2000-2006) - Head gasket failure (OEM gasket P/N 12251-PNA-003) affects all variants due to aluminum block/iron head mismatch
- H22A8: 2.2L VTEC (RN3/RN4, 2003-2006) - Oil starvation in VTEC system common across all 2.2L Stream models
- L18Z1: 1.8L i-VTEC (RN6-RN9, 2006-2014) - Timing chain tensioner (P/N 14520-RB0-003) fails identically in all 1.8L trims
- L20Z1: 2.0L i-VTEC (RN7-RN9, 2006-2014) - Shared cylinder head casting (P/N 12200-RB0-305) prone to exhaust manifold stud pull-out across all 2.0L variants
All D17 and L-series engines are mechanically compatible within their respective generations, allowing interchangeability between Stream trims when matched to transmission and ECU specifications.
Buy Used and Second-Hand Honda Stream Engines
For Stream owners, used engines carry high risk due to shared D17 head gasket and L-series timing chain flaws. Reconditioned units with updated gaskets (P/N 12251-PNA-013) and revised tensioners (P/N 14520-RB0-013) are strongly recommended across all variants.
- Reconditioned D17 engines: Include multi-layer steel (MLS) head gasket upgrades and resurfaced heads
- Rebuilt L18/L20 engines: Feature updated chain guides, tensioners, and oil pump revisions per Honda service updates
All engines are sourced from UK vehicles with verified service histories and undergo pre-rebuild diagnostics to ensure compatibility with the entire Stream series.
