      All I ever done when it comes to adjusting lifters is just leave them as they are I never rotate or rock the engine or lifters all I do is just go down the line and tighten them until there is absolutely no slack at all in the lifters and leave it at that and so far out of all the years that I've been doing mechanic work I've never had any problems yet

    This man has a calling as an instructor: never condescending in tone or manner, well modulated voice and eye contact, make for a viewer-friendly tutorial. I was looking for a visual to explain this procedure to my nephew, as my attempts to explain it, via phone call, seemed to be falling on deaf ears. This is an excellent presentation for someone like my nephew, that needs a visual aid. I was really getting frustrated while looking for an example of this procedure, as every other video I watched, treated the details of this like its universal knowledge and skimmed over or left them out.

    I am a retired ASE Certified Volvo Master tech. The 'rocking' method is the only method that is completely accurate, and this instructor is the only video that I have seen that is doing it correctly. Nearly everyone else is adjusting lash on the 'overlap'. I guess doing it on the 'overlap' is close, but not as accurate as the 'rocking' method.
    Great job on this instructional video.

      Hey Jimmy, I’ve seen that method too, but the big concern is trying to hear that specific rocker while all of them are tapping and also just how much preload you’re really getting on the lifter cup. Thanks for the question and commenting! Nelson

    • @markemery49
      @markemery49 ปีที่แล้ว

      Carl, please understand that we are NOT adjusting valves. (that is a misnomer).
      With a mechanical camshaft, we set the clearance between the rocker arm tip and the valve stem.
      With a hydraulic camshaft, we set the depth of the cam follower's (aka lifter) plunger.
      As I mentioned earlier, once a valve has been installed, the spring fitted, retained and clipped, there is no valve adjustment that can be made.

    F______ finally! I have been looking for HOURS(!!!) for a video that showed that the guy doing it, understood the fact that at TDC, for each cylinder, WAS NOT where the valve should be adjusted(!!!!). I knew that was an issue when I adjusted my valves on my 99 Ranger ( 3.0 ), but I couldn't figure out where that would be correct in the cycle, and almost did it the same way I did it last time (which would have caused damage AGAIN, although I don't want to explain more than that). But let me just say thank you for such a clear and well articulated video, on such an important part of the assembly, that is, for some reason, left out of the other ones I watched. I will definitely be hitting the subscribe button in a few minutes, something I don't usually do on ANY videos I watch. Thanks again, and keep up the good work!

    I agree that this method is the best on TH-cam! I have been adjusting mechanical (Not Hydraulic) lash adjusters for decades on mostly 4 cylinder import engines. Now my son needs his lifters adjusted on a SBC V8 in an engine I built him 6 years ago. His buddies all have messed with them and they are all out of wack. (I hate those wing-nut rocker arm cover bolts, they scream, take me off! NO! Those are for mechanical lifters & feeler blades)They all had different ideas on how to set them. I have the clip set that keeps oil from spraying while at warm idle running, but this is not practical on all. Now several cylinders are misfiring. I can't begin to tell you how well you explained this, to help my son (37) understand and how much clearer this old tech can show or explain to him and his buddies . They all can take them apart, but putting together is a different thing. Thanks!

      Hey, first off, thanks for the view! Having the manifold on is no problem, you can just watch for the pushrods to fall and rise instead of watching the lifters. If you take your time and monitor the “lash” you will know when you are at zero lash and then do your 3/4 turn from there. You can have a friend tap the starter while you watch them but it takes a very slight tap of the starter to get to the next adjustment.

      Great! The older Dodge shaft type (non-adjustable) rocker system can be “adjusted” by changing the length of the pushrods instead to get a desired lifter preload if needed. This is also the common procedure on the newer LS engines. Thanks for viewing and subscribe. More videos on the way. Good luck on your project!

    Just finished adjusting my rockers, went awesome because of your video. Since I had poly locks & can turn the nut with fingers, was to watch the lifter cup move up & down as I turned it back & forth. That way I knew exactly where zero lash was at by feel & sight.

      Hello my friend, I want to adjust my engine rocker arm, the reason because I hear a clicking sound in my valve covers, also one of the gasket valve covers is leaking oil so I want to take that opportunity to adjust my valves all because I'm going to be there around the valves so why not try to fix the problem, hopefully you can help me, I have a 1997 mercury mountaineer AWD 5.0L/302 it belongs to the Ford family, it's a V8 engine, do you think it is possible to adjust it myself I just do not have the specifications on how to adjust it properly but like you say by feel and sight it can be done. Would you please explain this method if it works on my car, thanks in advance for your help, if it's possible my friend. Thanks..

    • @mitchnelsonperformance
      @mitchnelsonperformance  2 ปีที่แล้ว

      Hey Scooter, You don’t necessarily have to view the lifters when doing the process, if the intake is on. You can also watch the movement of the pushrod/rocker arms if the intake is installed. You will see them move into overlap (the ROCK position). I’ve adjusted many engines that way. Just keep track of your cylinder locations to keep you on track. You can also use the ignition/starter to rotate the engine through the process but remember it only takes a slight bump of the key to turn the crankshaft the needed 90 deg. It helps to have a friend bump the key while you pay attention to the rockers. Good Luck with the project. Thanks for the comment and please like and subscribe

  • @terryking6266
    @terryking6266 ปีที่แล้ว

    Thank you Mitch!!! Seriously, you are a great teacher, even for us old motor heads that really only know the basics. I was gonna pull my plugs to make the turning over easier, pull valve covers. Just not sure if I should release the existing preload so that I can start fresh? Should I back them off a turn the eyeball each push rods movement?
    Thank you for answering, it means a lot to me, I love this truck👍

    • @mitchnelsonperformance
      @mitchnelsonperformance  ปีที่แล้ว

      Hey Terry, you can just back them off and then readjust them as you go through the process (I.e. you don’t need to back them all off first). Yes, a slight up and down feel of the free play will be felt in the pushrod or you can gently lift up and down on the rocker to valve tip until -0- lash is met. You may need to use a 5/8 spark plug or other thin wall socket because I’ve seen thicker wall sockets push against the rocker giving a false feel, or just pull the socket out and check free play then reinsert it as you adjust. Pulling plugs are optional. Once you get it in position (rotation) to begin, the rotations are only 90 deg so it’s fairly easy to rotate between adjustments. If you have a friend that can just feather bump the key, the starter will work great to run through it. Or you could bump it 60 deg and wrench it the other 30 😁Good Luck! 👍

    • @mitchnelsonperformance
      @mitchnelsonperformance  ปีที่แล้ว

      Also, you can still use the 3/4 turn and do the adjustment with lifters that already have oil pressure in them. The valve springs have enough pressure to “bleed” the lifter back under full valve lift during the adjustment process since there is no oil pressure until the engine is started up. You just won’t get that spongy preload feel that I show in the video when I’m rechecking my work due to them being full of oil.

    This is a seriously wonderful deep-dive. Question - when you are removing the slack or lash from the rocket, is there a precise way to determine when that slack is actually gone - such as using a feeler gauge? Same goes for after the 3/4 turn, how do you precisely tell if it's where you want it to be?

    • @mitchnelsonperformance
      @mitchnelsonperformance  10 หลายเดือนก่อน

      Hey Cory, first off thank you for viewing and the comment! If you can see the lifter you can use a flashlight to view the lifter plunger retaining clip. When the slack/lash is out it will begin to push down that plunger. Otherwise it’s not as crucial as you may think. Anywhere from 1/2 to 1 full turn is the range. The Go-No Go for lash/pre-load between the rocker and tip of the valve after the adjustment is made is .080 min to .180 maximum plunger travel when the lifter is on the base circle of the cam. Many engines do not even have adjustable rockers so you kind of get what you get. Good luck on your projects! Nelson

  • @holmgrown

    • @mitchnelsonperformance
      @mitchnelsonperformance  2 ปีที่แล้ว +1

      Hey Mark, The valve springs will bleed the oil out of the lifters as you turn the engine over as the rocker pushes the valve spring down. This will get the plunger off the wire clip in the lifter. The valve spring pressure has enough force to push the pushrod into the lifter bleeding the oil back slightly since the oil pump is not producing oil pressure unless the engine is running. You don’t necessarily have to view the lifters when doing the process, if the intake is on. You can also watch the movement of the pushrod/rocker arms if the intake is installed. You will see them move into overlap (the ROCK position). I’ve adjusted many engines that way. Just keep track of your cylinder locations to keep you on track. You can also use the ignition/starter to rotate the engine through the process but remember it only takes a slight bump of the key to turn the crankshaft the needed 90 deg. It helps to have a friend bump the key while you pay attention to the rockers. New lifters on a used cam is fine. Old lifters on a new cam or swapping used lifters from hole to hole on a cam is a bad idea. Good Luck with the project

    I have always made sure they were all pretty loose on install, and then did each cylinder individually. I rotate until one valve is fairly open and take the play out of the other. Rotate again to open the other valve and close the gap on the second valve. Repeat for all cylinders. Then I adjust with the engine running, backing off each rocker until I get a tick, waiting a few seconds for the lifter to pump clear up.. Then I close it down just enough to remove the tick & go 1/2 turn more. Some guys like 3/4. It's easier to me and never fails.

    Hi Mitch. I had to replace spring retainer and a pivot retainer on a 1998 dodge ram 1500 5.2L so I had some lifters that had bled down and some that didn't. Both intake and exhaust lifters on the #7 cylinder were still rock hard after sitting several days so I used a washer etaped to the top of the push rods to "convice them" to bleed down, but they're still "firm". I wanted all of them to be approximately the same before making the adjustments. What should I do?

    • @mitchnelsonperformance
      @mitchnelsonperformance  6 หลายเดือนก่อน

      Hello, sorry for the late reply, usually if the engine sits for a little time with that lifter/rocker at full valve lift, the valve spring will have enough pressure to bleed the oil back in that lifter. It’s a slow bleed down time so it may take some time. Then rotate to the next lifter/rocker that needs bled. You would need to do this by hand because using the starter can at times run the oil pump fast enough to produce oil pressure back in the lifters. Hope that helps and thanks for the kind words and viewing, Nelson.

    Definitely informative for those of us getting ready for the ASE A1 test! Now I'm able to visualize the concept of hydraulic lifter preloading. Thank you so much for such a great information!

      Hello, I’ve taken all 8 myself as well. Good Luck on your test and thank you for the comment! Perhaps our channel should think about possibly doing some ASE test review info videos? Thanks for the thought. Nelson

      @@mitchnelsonperformance buddy, just took my test and passed!! The very complex exam did contain several questions regarding push rod engines including pre-loading and your video definitely helped on my test. I wanted to thank you once more for taking the time to explain this! 🙂

    so if you have the timing marks lined up & adjust # 1 cyl, could you just turn the engine 360 degrees so both timing marks are @ 12 o'clock to adjust # 6 cyl ?, thanks for an excellent video

    I agree with everyone below! Clear and concise description of how to adjust hydraulic lifters. Thank you! I adjusted mine in a 304 V8 this afternoon. Small wrinkle compared to the video: some of the adjustments would not permit a full 3/4 turn. The nuts were too tight. Some felt deceptively loose after 3/4 turn. Are the lifters worn and that's the reason for the increase in force felt during adjustment? Thanks in advance!

      Hey John, it’s been a while since I’ve done an AMC but I was thinking they were non-adjustable? Does yours have adjustable lock style jam nuts and studs? Also wanted to point out that AMC heads had some really good flow potential on our flow bench back in the day. Go Underdogs! 😁 p.s some lifters may bleed back easier when turning the engine over making them seem easier to preload.

      @@mitchnelsonperformance GM MItch. Thx for the reply. I've learned that the bolts only have a torque spec not a 3/4 turn as do the stud based system in the video. My lifters are primed so I may need to keep some pressure on them to bleed them out for proper preload. I will torque them on the combustion part of the cycle (TDC) as is described in your informative video. I believe this should do it. Thoughts? Thanks!

    • @mitchnelsonperformance
      @mitchnelsonperformance  3 ปีที่แล้ว

      Hey John, yes that sounds correct. The valve springs will bleed the oil out of the lifters as you turn the engine over as the rocker pushes the valve spring down. This will get the plunger off the wire clip in the lifter. The valve spring pressure has enough force to push the pushrod into the lifter bleeding the oil back slightly since the oil pump is not producing oil pressure unless the engine is running. Good luck on the project!
