I’m hearing this strange noise coming from the engine do any of you know what it may be???? (Not the injectors). I changed my oil 3k miles ago but recently the I noticed this noise I came to check my oil which I do occasionally and it’s always been in the half between both dots but when I went to check it recently it was at the first dot so it burned up some of the oil. I changed my pcv valve today it probably won’t solve the problem but the old pcv was still good still rattling.
