hi, my girlfriend has a fiat grande punto 56 plate. she has a oil light that flashes and at the same time she gets a tapping sound coming from the engine, i topped it up with the correct oil but still doing the same thing. we took it to a mechanic and he said he couldnt find any leaks cracks etc. i spoke to a few people about this and they think the engine is on its way out (hope not). i googled the problem i got and think it could be hardened oil thats stuck somewhere and that it might just need flushing out. any advice please?
