Dont take this the wrong way but the truth is often frowned upon. Im talking about the bearing caps. If your really not sure as to what im talking about then this isnt the job for you. You said you already found metal in the oil....that a sure sign this engine is on its way out and on its last leg. Metal shards/shavings is a sure sign of oil starvation which leads to bearing failure, thus spun bearings.Should I start by getting a new pick up tube and do new oil and filter? I found small metal shards in the bottom of the pan when i pulled it off. What caps do i have to pop off? What else can i check for before calling the engine broke. The car ran and drove fine, it just had that clanking sound. Which direction would you go in with the car?
This kind of stuff has been covered a thousand times over the years here. If you dont believe me then you can search around for yourself. This is not just a "simple knock" This is very serious and borderline catastrophic engine failure. That is the next step which will result in the engine not running at all. Like ive been saying, the car needs an engine rebuild
