When I first start the car it sounds like a bucket of bolts flying around inside the engine...it then settles down and just does its job. I'm guessing its time for rebuild but how do I know for sure? Would bad bearings cause that noise? There is also a good bit of oil dripping from the tube that hangs down near the oil filter canister....not sure what that is or what its for. Just today finished the interior of car and would like to enjoy driving it awhile but don't want to break down either. Drove it around neighborhood and had no problem but afraid to take it on highway.
