hi all new to this forum
i was wondering if anyone has any advice regarding a problem i have with my engine on startup i'm getting a lot of rattling that eventually dies down to a constant ticking not being an expert with diesels i was wondering if this would be down to hydraulic valve lifters (are they even fitted to this car?) or something more hideous!! the engine has done around 260000 kms
any advice greatly appreciated
