Hey guys just found out that my upper timing covers are leaking when i got the air filters replaced along with an oil change.

I got the car a few months ago, 2 owner car, cert pre owned before me and everything but I feel like every time I start up in the morning theres a rattle, I posted the video.

Can you guys tell me what you guys hear, please I need an expert to listen to it as I want everything fixed so the car can last 300k miles. I am at 103,800 currently.

One other thing to note is once before (like 3 or 4 weeks ago) i tried to start the car and the car did not crank then when i took out the key and reinserted it, it started fine. although I had my old battery on at that time (original 10 year battery) when that happened but since then I changed the battery out a few days ago and not had it repeat or anything.

Your engine start-up sounds 100% good at this time.

Cold start rattle will begin under low pressure conditions when oil had enough time to drain out from engine heads.

Once rattling parts are worned out don't delay repairs to prevent additional expenses of replacing new camshafts.
