Simply the best: PHC Rolls-Royce & Bentley V8 Cylinder Head Gasket now with a 3-year warranty




Manufactured to the highest standard and designed to solve recognised issues with the original equipment (OE) part, the Peter Hepworth Components (PHC) V8 Rolls-Royce & Bentley Cylinder Head Gasket is distributed exclusively by Flying Spares.

Reports of V8 Rolls-Royce & Bentley head gasket failures first surfaced in 2015, frequently due to blistering of the red bead which allowed coolant to escape. In 2019, further failures were reported, this time of engines leaking immediately following head gasket replacement.

Suitable for most 1959-2004 models (notably excluding the 4.4 litre Bentley Arnage), the PHC V8 Rolls-Royce & Bentley Cylinder Head Gasket now comes with a three-year warranty.

The modified PHC gasket, slightly thicker than the OE part, uses the very latest manufacturing techniques to include copper in the fire ring and coolant and lubrication channels. This allows the gasket to compress more easily, giving a better seal between the crankcase and cylinder head, especially when the surfaces are not perfectly flat. The body is made from a composite material based on graphite and aramid fibres, giving high compressibility, stress resistance, and flexibility.

Head of Quality Control at Flying Spares, Malcolm Crane, said: “The V8 Rolls-Royce & Bentley head gasket is a recognised industry issue which has caused problems for dealers and enthusiasts around the world. Unfortunately, unless the cylinder head was pristine, the OE part was simply not fit for purpose. We, therefore, tasked PHC with designing a top-quality aftermarket solution.

“On a personal note, my thanks go to metallurgist John Smith, sadly no longer with us, for his expertise and commitment to the product development. The results speak for themselves; we’ve supplied over 1,000 of the PHC units now with zero fitment issues reported and zero warranty claims.

“It’s a great example of the UK aftermarket stepping up to meet a global service and repair requirement. As so often, PHC exceeded the OE specification, solving a long-standing issue and delivering peace of mind for customers on a previously tricky job. Our confidence in the quality is reflected in the decision to increase the warranty from one to three years.”

Supplying OEM quality into the automotive aftermarket for 50 years, with roots going back to 1907, ISO 9001 certified PHC parts have been distributed exclusively by Flying Spares since 2018.

Please note: The V8 Rolls-Royce & Bentley Cylinder Head Gasket is not designed to work with sealant.
