I'm not aware of a 357 engine in a '69 Chevy. I'll assume it's a 327. The rocker arms in that engine get their oil from the lifter through a hollow push rod. Make sure you can see through the push rod and the hole in rocker arm is clear. If everything looks OK you probably have a problem with the lifters.
hold up rod bearings were did you get that?lets take it from the top.camshaft lobs move lifters on rotation,which lifters move push rods,push rods push valves up and down,which other side of valves push up and down valve stems,which open and close exhaust and intake stems.ok now were clear on that to see your push rods.take off your valve covers on side with tick.1.check for valve loosness.need a feeler gauge for this and specs for you truck to do this.because ticking is mostly associated with valve loosness or to tight.2.if rod is bad loosin valves but not off and inspect the rods for bends.on a flat surface.replace if bend.also make sure they to go back in same place.and repeat step 1.finally noise continues need to take in and checked possible internal damage.
Where did it go?? Just wore through? You have to get the lifter out of there and replace it with a new one, or a used one. For some reason, it is not getting oil. You might be finding more damage as you go. One of these days you are going to have to fix that engine right, new cam, lifters, etc. You can make a hook out of 1/4 inch rod, grind a flat spot in it with a small shelf left at the bottom for the hook, it will grab the edge of the lifter and pull it out. Hope this helps.
The 1.6 has hydraulic non adjustable lifters and that lifter tick has been a thorn in their side ever since the 1.6's inception.
The way to eliminate the noise is of course replace the lifter/lifters use a cam lube on the lifters bottom and let the new lifters soak in an oil can overnight.
Check for bent push rods when you have it opened up, R&R valve cover,R&R rockers R&R pushrods, Remove and Replace the lifters.
Hello, my name is Ben. Sorry to inform you, but when you turned the crank it turned the camshaft which is why the lifters are in the wrong place now. You will need to set the camshaft timing and re-install your rockers and push rods. You should also check the push rods to make sure none of them are bent. I hope this helps you to get your engine running properly, Ben.
push rods dont knock?? they are hollow rods that the lifters push up and pump oil thru to rocker arm that then pushes down on a valve and opens it if u bent the push rods or any other part of the head valve train most auto parts stores or on line parts sell them including dealer
If it has push rods, you will find them under the rocker cover on the top of the engine, they are hiding under the rockers. The rods ride on a lifter that rides on the cam and then they push the valves down, and squirt oil all over everything, a spring brings them back up. The overhead cam eliminated all these extra parts. Lifters, rods, rockers. Hope this helps.
Since you already have had it apart, you know at what point you can see the lifter. Lifter pulls straight up out of its bore, new one drops right in. If cam contact surface is worn concave, you need to replace cam as well. Always use assembly lube on lifter/cam contact surface when installing.
