I have the same sound but I've been told that its a gasket leak from either in front or behind the exhaust manifold

    i tried to check it out but don't have the tools or money to take the exhaust system off

    If it is knocking it is not a gasket. Take valve cover off and see if the any rocker arms came loose.

Carried my 2005 free star to local shop and they said they thought it was a lifter or a rocker arm problem it makes a loud knocking sound..


Takes about 1 1/2 hours to figure it out. I can remove both valve covers in about an hour. 15 to 20 minutes to see which one is bad, if one of them are bad. Lifters and rockers arms usually make a ticking sound. Knocking is usually the piston rod. could be bearings at the crank or the wrist pin at the top of the rod. I've seen valve springs broken and only cause a ticking noise.

Knocking noise dodge ram


Pull valve cover off and look for any bad lifters. Or could be piston rod. Sounds like sticky lifter. Not good.

Lifter knocking in my 89 ford ranger


A lifter problem can only be fixed by changing the lifter. You might as well change all of them because it is just as easy since you have already had to take the heads off to get at the noisy lifter. While you are at it, get the heads reconditioned or a valve job. More than likely the oil was not changed as often as it should have been. Dirty oil works like sand paper on the valve stems.

How do you no if your lifters are going bad


Bad lifters will make a loud "ticking" sound. This noise can be isolated from other engine noises by putting a section of rubber hose (like a heater hose) up to your ear and using it like a stethescope. Lifter noise will be coming from the valve cover area.

2009 Ford Flex when started first thing on a cold morning it ticks/knocs really really loud, once it warms up the ticking goes away to a very light tick. The dealership ruled out an exhaust manifold leak....


It does sound like a valve lifter problem to me also. It should be covered under warranty. It's a mechanical failure of a component of the drivetrain. Ask them to show you the specific exclusion if they say it's not a warranty problem.Powertrain warranty is 60 months/60,000 miles ( which ever comes first).

There is a loud knocking noise under the right valve cover, what could be the cause?


It could be a collapsed lifter, a bent pushrod or a bad rocker arm. It could also be a bad piston wrist pin or rod bearing, and the noise sounds like it's up top.

I have a loud knocking noise coming from Under my valve cover. How can I preform a valve test to find where the knocking is coming from


It is generally just a noisy lifter. This happens to about every 3.2 liter isuzu I have ever seen and didn't really hurt the performance.

Have a 1990 Z71 4wd that with loud engine knock.


I'd consider some fresh, clean oil & filter change first of all, if it hasn't been done . drive it for a while providing it isn't too bad, & see if it goes away, if not get back to us.

My friend just got a 1988 ford ranger  v6 2.9L and has a valve tap and was wondering what different kind of ways he could fix this


if its an ohv type the most common fault is that the oil ways to the rocker shafts become blocked
so get some flushing oil drain the oil and replace with the flushing oil and run for the time stayed on the can then Change to good quality oil and new filter
then remove the rocker covers and check and adjust the valve clearances
if its an ohc type its all hydraulic adjustment
you could try flushing as above but apart from that the only other way is to change the lifters and followers
hope this helps
