Hello,
Hope you are well!
We are just finishing to install the bolt ons on the car: lower pulley 15%, big gulp, headers catless and x-pipe with stock mufler.
Doing the lower work, we changed the oil pump and the two tensioners for the belt. The car did her first miles with the new mods fine, but today started with a very noticeable and annoying whine at idle.
Has someone any idea what is the cause of it?
Thank you!
