Really, really, sorry to suggest that the head gasket may not have oil passages lined up. Always lay the oil gasket over the new gasket to see if each and every hole is punched out and lines up to the old gasket.

Also, each lifter needs to go back to its original spot. The Cam lobes are worn for that lifter and a mismatch can be possible. A mismatch could mean extra play in a badly worn lifter face mated to a badly worn Cam lobe.

If that is what you did then get new or rebuilt lifters. Check out Compcams.com for a detailed description of each engine scheme. Your engine may have a thrust plate for the lifters and it may be incorrectly installed creating noise.

SOURCE: lifter noise

If the engine runs good and has high mileage, it might be the timing chain guides that are worn out

SOURCE: misses when hot also lifters become noisy

The camshaft may be worn or the lifters .that explains the missing when you run it at operating temp.By the description of the oil. the reasomn the canmshaft wore out and the valve lifters is because the oil was not changed on a regular basis.

SOURCE: replacing lifters on a 79 pontiac firebird

Remove valve covers, remove rocker arms and push rods, remove intake manifold, remove lifters, (special lifter tool may be required). Reverse steps to reassemble. Make sure to use new gaskets.

SOURCE: noisy lifters?

some anti freze may have entered the oil when repairs wrer done, check oil first, but the 3.1 has solid lifters and is a comon problem to make ticking noise, the lifters are about $60 each x 12, my friends olds 3.1 has made that noise for 10,000kms now, wreckers may be an option

more than likely you will need new lifters but i have gotten away with substituting 1 quart of atf for one quart of oil on an oil change that seems to work good and make sure you don't use any thick oil treatments and are running 5w30w oil..

Stop noisy engine lifters


You are probably running low on oil unless you have been dogging the engine from red light to red light then you probably stretched the push rods you can also tighten the lifters

Hi. I can give you a simple, but time consuming test to do to check your intermittent compression problem. New hydraulic lifters cause a lot of problems until its settled. Remove the camshafts and the hydraulic lifters. Take each hydraulic lifter and put it in a vice(becarefull not to damage them) and squeeze out all the oil in the lifters. Then put them back and replace camshaft and allign timing marks. Check compression ratio. What happens sometimes is that the oil pressure is too high(stuck oil pressure release valve or cold thick oil) and this causes the oil pressure to put so much pressure on the hydraulic lifters, that it slightly forces the valve open. That will cause your low compression as well as backfire through the intake.

Why doesnt my 2006 dodge ram show codes for faulty lifter or or oil pressure. My truck makes a loud ticking sound coming from passenger side. sounds as if the lifters are knocking. took it in to the shop...


Most mechanical problems, such as noisy lifters or bearings, can't be detected by the engine controller and thus there won't be any codes set UNLESS the problem is causing a misfire or emission related concern. The ticking noise may well be a lifter even though none of them appear to be collapsed as the spring inside them will keep the lifter expanded but isnt' strong enough to keep them from being noisy when the lifter can no longer keep oil under pressure trapped inside. You may have to have someone do some further testing and inspecting to figure out exactly where the noise is coming from. Good luck, hope this helps!

Where are the lifters & how do you change them


The are inside the head. Best way to access them is to remove the valve cover and you will seem the cams, rocker arms, and under the rocker arms are the hydraulic lifters. Just a fyi if you remove a lifter make sure you put it back in the same spot. Label everything you take apart!!!

Oil leak from rocker box on 1996jeep cherokee2.5td


Get you a new gasket for the rocker cover, make sure you clean the mating surface good,and all traces of old gasket, and silicon etc. make sure you dont overtighten the bolts to the rocker cover. the torque for the rocker cover is 35 in lbs (4nm). as far as vavle clearance it is none adjustable. A clicking valve can indicate worn lifters, sometimes an oil change will quiet down noisy lifters. If noisy lifters persist you would have to service the heads. If you decide to do that yourself you can ask for a procedure on that too later on. Removal of the head is very difficult, because you need to remove a lot of things, and require you to do a timing on the engine.

Noisy lifters?


Did anyone leave any rags under the intake?
I had a client have this happen to him and it caused some real problems.Check the oil level to see that it's not low. If you have an oil pump problem, the light should have come on. Hope this helps a little.
