Same here had my 160 in the garage last week to have a pipe replaced and got them to check the engine. They told me it was normal for a VVC engine and worse when cold. I just drown out the sound with my Xpower exhaust anyway :up:Mitchy said:Hydraulic tappets are supposed to be noisy. After a spirited drive mines would be very noisy, in the morning when first starting up they would be a lot quieter.
Garage said it was completely normal, although im unsure of the 1.4 engine, its completely normal on the 1.8vvc.
If a piston goes, you'll know about it.
