R5 Turbo Gasket set

Cylinder head gasket & specific features of the Cléon type 840-730 Renault 5 Turbo engine

The Cléon type 840 engine, fitted notably to the Renault 5 Turbo, has several specific features. Metrology checks must be carried out and must comply with the required specifications, but that is not enough.

Essential points to check

• Camshaft clearance in the engine block: many Renault 5 Turbo engines suffer from low oil pressure due to excessive clearance.
• Do not install a solid steel camshaft: for physical reasons — Hertzian contact pressure and gear resilience — this does not work properly. Prefer an original camshaft, whether with the original profile or reground, or our camshaft.
• Tappet inspection: check their condition and material. Our tappets are compliant, manufactured from the Renault drawing and according to the manufacturer’s specifications.
• Avoid oil pump rebuild kits: they do not work reliably. So-called “high-flow” pumps offer no real benefit; please refer to our video on this subject.
• End float & distributor drive gear: camshaft end float is essential. Only fit original cast iron distributor drive gears.
• Liner protrusion height: this is a key factor for proper cylinder head gasket sealing, both between cylinders and against external leaks.
