engine noise
i just recently purchased a 94 g20t . ive already replaced the distributor with the crank sensor built in, and the starter. but now its making a weird noise coming from the left side of the engine. sounds like metal pinging(when i am accelerating you hear it alot more, but at idle it is still noticeable) . i brought it over to the shop to have them take a look. ( i thought it was the water pump or pulley going, but it's not) even they dont have a clue what or where the sound is coming from. could it be the timing chain or belt tensioner? any help would be helpful
