So I've found a nice car And the seller says the clutch is heavy so will need replacing. How can I check this as I'm new to diesels? Also it has had new camshaft shells and pulleys as he states it was noisy. Does this sound right, what would cause that? Im going to view it so what should I look out for? Oh also it's the 1.9tdi 115 engine. Would that be pd engine? Is that a good engine to buy.thank you.
