Quick question regarding an apparently common fault with the HR (2007, 86k miles). My oil pressure is reading quite low at hot idle - around 10-15psi - and I'm aware it could well be the oil gallery gasket needing to be replaced. My issue is with trying to get a garage to externally measure the oil pressure and/or replace the gasket. Does anyone know of a garage/specialist in the Southwest who would be able to do this? If all fails I'll have to take it to Horsham. Cheers.
