OE Hydraulic cam follower to fit the Rover V8 as fitted to TVRs. This is the OE hydraulic cam follower from Delphi and is probably the best quality cam follower currently available for all Rover V8 engines. The cam followers must be replaced when the camshaft is renewed. See TVR E0274 SET for full engine set at a great price. These hydraulic followers should be soaked in engine oil overnight to help prime them for the initial start up. Dont be tempted to fit cheaper non OE parts for this application. These lifters have been fully tested by the OE camshaft suppliers and confirmed as the best available. See the TVR E0274 SET in linked parts for an even better price for 16 for an engine set if you are replacing your camshaft.
