Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
Hello. My name is ***** ***** I will be helping you today.
Why would you assume that a part that you cant even say for sure exists is causing a noise?
Can you better describe the noise?
Is there any other symptoms?
Is the check engine light on?
Can you try to narrow down where on the engine the noise is coming from?
I can assure you you didnt hear anything with the heads off ;) You mean the valve covers Im sure.
Are you able to check the codes right now? Are you certain you didnt lose anything in one of the spark plug holes while you had them out?
If its going through a quart and a half of oil in 4000 miles you are probably best off putting your money towards a lower mileage salvage engine. Especially if you are capable of putting it in yourself. That engines seen better days and the knock sounds pretty serious from what you describe though without hearing it myself I could be off base on that one.
No problem. Just reply if you need anything further and please be sure to rate my service so I get credit for helping you today. Thanks
