we got the neon salvaged at 28k I used to push it to the limit alot and it started leaking oil from the head,.... the head gasket was swapped but im wondering if the timing belt got swapped too ?? i know the water pump did though,... well one day on the free way i floored the pedal and soon after like a reving noise noise is heard kinda like an after market intake when its just in park or being driven,... could a loose or faulty timing belt cause this? any suggestions? the person who swapped the head is not around... so i cant ask him if he swapped the timing belt
