well really it depends if its a top end knock or a bottom end knock either way it is a tear down and a internal issue you can try risilone engine treatment but @90 k i would learn to deal with it because 1 its usually not cheap and 2 if you did fix it it still has 90 k on the rest of the engine you also can try stuff like lucas oil stabilizers but its just sounds like wear and tear i could be wrong but engine knocks are usually internal and in most cases not cheap to fix
ZACK, YOU are responsible for this problem IF you are getting el cheapo oil changes. Your engine was DESIGNED to use SYNTHETIC oil that protects engine bearings and timing chain tensioners. HOPEFULLY, the knock is just a noisy valve lifter. If not you are in BIG EXPENSIVE TROUBLE!!! NEVER use conventional $20 oil changes unless you like expensive sensor and engine failure!!! If this is just PING< then here is your ANSWER!!! Your engine has a REMOVABLE idle air control valve. (IAC) This thing regulates fuel mixture by adjusting incoming AIR amounts, not fuel. It is EASILY cleaned with solvents, and returned to operational shape. CLEAN your THROTTLE BODY as well. MOTOR FLUSH your engine and use ONLY Mobil One 0W-30 or better 100% synthetic oil. Change it once a year, The pay-off is better power, economy, lower emissions, and oil changes that last for an entire YEAR or even longer!!! Total cost for this repair is about $20 for the cleaning, and the cost of the flush and GOOD motor oil. STAY AWAY from wax based engine oils that MAKE th sludge that RUINS engine sensors. TRUST ME! It's the TRUTH, ruth!
Please don’t SHOUT with all capital letters. It detracts from your message.
Most likely a rod bearing. Better get them all replaced now before you need a complete rebuild (or tiny a rod out the side of tug block). Change oil pump & clean/replace pick up screen. Low oil pressure and worn crank bearings will starve the rod bearings for oil.
