'98 Civic engine knock after alternator dies?! Need Help!	Sign In

I have a '98 civic EX coupe with around 160,000 miles. The car was mechanically running perfectly fine ever since I have had it, only issues were minor such as window motors, etc.

The oil was changed with it's usual 5-30 full synthetic and a mobil 1 oil filter less than 200 miles ago. It was completely full of oil this whole time.

I was driving at about 45 mph when the car suddenly dies and I was barely able to coast into a safe spot off of the road. Now that I think about it, the car engine did seem to start running substantially louder (kinda like you are really low on oil when the engine just seems a little bit "ticky"), but this was only for a few seconds before the car died.

The car wouldn't even try to start. I tried hitting the alternator with a metal rod I had in the back. This made the car start to turn over or almost start, but not quite.

Last night I had the alternator changed. The car cranked right up. The engine makes a horrible knocking noise like there is metal in the engine synced perfectly to the RPM's. At low RPM's it is a knock, at high RPM's it is a grind.

What could it be and why???

The car has no check engine codes

We can't tell you what the noises are or where they are coming from through our computer. Someone is going to have to inspect it "on site" to give us some idea what happened before we can have any idea why.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

You could also record or video the noise and upload it into a video hosting site such as Youtube. Then send us the link.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Why would you hit the alternator with a rod? I can understand tapping the starter, is that what you meant?
