so recently, my car has been grinding on a cold start. I don’t know why, but when the car gets warm enough once you hit 5K RPMs, it starts misfiring, and I don’t know if these two are linked. I had a bad, spark, plug O-ring which I believed to be causing the misfire. since then I have replaced the bad old ring and remove all the oil. But on start up hear a strange, grinding noise I’m not sure what it is. Any ideas?

 

Can you take a video and send?

Did you change the spark plug or plugs that were in the leaking chamber? The oil usually messes them up permanently

 

No i haven’t changed the spark plug yet but im going to soon. also it is not letting me send the video do you have another platform i can send it too

 

can upload it to youtube then send us the link

 

Ok here you go
listen closely it sounds like a angle grinder but it only happens on cold start
