I know pretty much nothing about your particular vehicle or how well you maintain it , but I am compelled to sugest that you ensure that your engine oil is not low , and that the filter was changed a reasonable amount of time ago. Low oil flow or pressure could cause the taping.
Also , many chrysler products require mid grade or premium fuel or they will knock/ping.
I hope I have not insulted you with such a overly simplistic response , it's just that on this forum , it is very common to find problems from people who don't have much mechanical knowledge.
Just trying to help out.

I got an infinity 2005 g 35. I'm starting to hear a knocking noise. I don't know if its the engine, It sounds like it's coming from the side somewhere but definitely under the Hood.? Idk


if the knock speeds up with rpm increase then it definitely is the engine. if it is a solid sounding knock that would be bottom end. if it is more of a hollow knock or more like a tick then could be top end...lifters, exhaust leak or check to see if anything is hitting your cooling fan.

1999 3.0 ford ranger knocking at idle only


It sounds like a valve or valve lifter issue. First check and make sure the oil livel is where it needs to be. Then, I would let it idle for a few minutes and see if the knock goes away when it warms up a little (still idling). If not, its a bit more in the advanced stages of a valve or valve lifter going bad. Either way, I would change the oil with some high quality synthetic oil and get a filter with a non drainback valve (k&n or Mobil 1 has them for sure). Those attempt to keep the oil in the top half of the motor when you shut it off. I would always let your car run for a minute (longer in winter) before you drive it to get the oil pumped up and circulating.

What can cause a knocking at the right hand side valve cover


Hi , usually a knocking / pinging from the valve cover indicates a lifter tapping. Could be worn out or just worn. Do you change your oil every 3000 with high quality oil? (I always have used valvoline standard with outstanding results) Dirty oil and filter and or incorect weight oil and or using synthetic oil in older cars can result in lifters tapping. If your oil is under 2000 miles since last change and you used a high quality oil (watch who changes your oil, some places use inferior oil because its cheaper) you can buy a pint of oil treatment formula to quiet noisy lifters to coat the lifter and quiet it down. It is a sign of engine wear, but one lifter tapping a bit wont really hurt your engine mechanically. If they all get noisy, time for a valve job. Root cause is wear due to insufficient lubrication. The lifters on newer cars are all hydraulic and they self adjust. No manual adjustment is possible. Bottom line: keep your oil changed regularly using a high quality non-synthetic oil for your 1999 vehicle.
Please rate this answer! Thanks, Mike

MY 6L V8 makes a loud knocking noise only when it first starts for only about 30 seconds then you never hear any more knocking for the rest of the day Is this a valve problem?


In some oil filters they have anti drain back valves in them, what keeps oil in the filter when sitting for a long time. this helps get oil to ur top end quicker. If not i takes longer to get oil to ur rocker arms so you might hear a knocking or ticking for a while. Try when u do ur next oil change to get a filter it a anti drain back valve and that should help make that noise go away quicker.

It could very well be a valve or lifter. The low oil may also cause the lifters or rods to knock.
As long as you aren't loosing oil or coolant, jeep runs good, and the knocking is not extreme, than add oil and you should be ok.

Engine ticking


Yeah its a hydrolic lifter or the big end bearing (hopefully the hydrolic lifter as its much cheaper to fix) does the ticking go away after 5,000 rpm?

Valve knocks when running reaches 1500 rpm


First, nothing you have done has anything to do with valve tappet noise. What is your oil pressure? Have you positively identified the noise as a lifter (tappet), OR COULD IT BE AN ENGINE BERARING OR WRISTPIN? Other than tearing it down and replacing lifters, rockers or pushrods or possibly even the cam, if oil pressure is good, change the oil and put a quart of Marvel oil in there. If that does not clear it up in a few days, you will have to go inside the engine. You likely have over 160k on that engine...consider using a replacement. Get an older tech to listen to it...it takes years to be able to differentiate between different component noises with any accuracy.
Personally, without hearing it myself, I'm betting it's a rod knock.

valve lifters make a kind of rattly knocking noise! which sort of follow engine revs.if they are gone you may need a new camshaft as well, best to do itr all at the same time and are sold as a kit.are you sure there is a new noise or are you just listening harder?
