So last week i brought my car to the dealership and had my timing tensioners and guides replaced as well as all 3 chains. I wasnt going to replace the primary until the tech found out that my problem was on the primary. Anyway $1080 later i picked up my car and everything sounded great until later that night i kept hearing this loud screeching sound coming from under the hood. Thought it might have just been a belt at first until i started my car last night and it was worse than ever and didnt stop till i reved the engine a bit. Any ideas and could it be related to timing work??? It only usually does it when you get on the throttle like into passing gear or tach it out in park
