  1. Install the pushrods in their original location, making sure they seat in the lifter sockets.
  2. Install the rocker arms and ball, then tighten the nuts to 14-20 ft. lbs. (19-27 Nm).

1994 dodge 3.9l v6 what direction (up or down) do I put the oil hole on my lifters?

Hi Franklin:
All of the engines I've played with that had hydraulic lifters also had hollow push rods. The lifters act like little pumps and oil comes up through the push rods to lubricate the end of the rocker arms.
My answer:
flat end down onto the cam
hole end up for the push rod to sit in.

If ticking sound don't go away after flushing oil change is there a need to repair engine

Ticking sound is typical of slack in the valve train. Try using a wood dowell "stethescope" and touch it to the rocker arm cover over each cylinder. If a rocker arm adjustment is too slack, you'll hear a clicking sound rather than a muted murmur. If you find the noisy lifter you will need to remove the rocker arm cover and adjust it. CAUTION NOTE - It is possible that a hydraulic lifter may have some grit in the internal valve. That would stop the lifter from functioning properly.

Tikking noise coming from engine

Yes, you're right, those could be the cause. Also, possible it's a collapsed hydraulic valve lifter, if your car has hydraulic operated (from engine oil) valve lifters. At any rate, it sounds like something loose in the valve train-valve lifter with push rod engines; or cam followers {rocker arms) with overhead cam engines that push on the top of valve stems .
Check a repair manual to see if your engine has valves that can be and need adjusting. Engines with valve lifters do not require periodic adjustment for proper valve clearance. Engines with rocker arms do require checking the valve clearance every couple of years or so.

There is no valve adjustment on that engine. Your rocker arms are on a single shaft that us bolted to the head. The lifters are hydraulic and will take up any normal slack unless there is damage to the cam, lifter, push rod or rocker.

Can noisy Hydraulic roller lifters eventually turn into a loud knock. 4.0 motor

Possible. I have replaced the roller rocker arms and push rods because they get clogged and wear out both parts. I guess if left to long they would punch a hole threw the arms and knock alot louder.

Why rocker arms wont pick up oil in 1969 357 chevrolet

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.

I have a lifter that it ticking on a 1989 Mazda 323 Se with a 1.6 liter engine . . . Can it be adusted?

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.
