  • This applys to sbc, bbc, and up to the 90's LT1 engine. This is not applicable to the LS engines.
    In this video I have already installed the hydraulic lifters, pushrods, and rockers. Now we are going to set the valves to zero lash, without having the engine set to any certain point. You can do this without having the valves, lifters or cam in a certain positition. Just keep checking for zero lash on all valves making a quarter turn between checks. You will need 2 full revolutions on the crank to make 1 revolution of the cam. Once done you can set your lifter preload to maufactuer specs, and lock them down depending on your set up. This is on 7/16 20 rocker studs. One full revolution on rocker nut = .050, so addtional half turn gave me .025 preload on hydraulic lifter.
    If you have 3/8 24 studs half a turn will equal .021
    If you are running solid lifters you will need a feeler guage set to set your valve lash. There is no preload on a solid lifter.

    Just watched another video by someone named Ken who taught the exact same technique. You're also making it W-A-Y too complicated. Most shop manuals will show that if you put the engine on #1 TDC, you can adjust half the valves, then rotate engine ONE turn to put sister piston (the one that comes to TDC at the same time as #1) on TDC and adjust the other half of the valves. On SBC engines, go to #1 TDC and adjust exhaust valves 1,3,4,8; intake valves 1,2,5,7. Rotate to #6 TDC and adjust remaining valves: exhaust 2,5,6,7 and intake 3,4,6,8. Also, as you reach zero lash, go ahead and turn down the rocker arm 1/2 to 3/4 turn (hydraulic lifters only) before going to the next valve. Should be able to do this in under 5 minutes. It doesn't get any simpler!

      Most “shop” manuals are not covering performance applications! The shop manual method does work for stock applications. A hardcore performance engine builder will adjust one valve at a time with a degree wheel with the cam lobe being 180 degrees of cam rotation from max lobe lift. This ensures you are in the middle if the cam lobe base circle. I prefer doing it the W A Y hard method to ensure it is done correctly. Performance cams have much longer durations and you want to be sure the lifter is on the base circle.

    I got a hydraulic lifter Puller and pulled them all first and took them apart and cleaned them first. My girlfriends Nova 1970 hasn't ran in a while so I noticed the lifter not compressing. After I cleaned them and reinstalled them I did this method. Thanks for this video.

  • @majoraslayer64
    @majoraslayer64 9 місяців тому +2

    I'm having trouble understanding what I'm feeling for in the pushrods. I think where I went wrong was feeling for up and down movement to see if both ends were making contact. It looks like you're making a point to only push up on the rod to see if it makes the rocker move, and I'm wondering if by applying very light pressure downward while jiggling it, I was messing myself up by slightly compressing the lifters. For some reason I'm not wrapping my mind around feeling for drag, because it feels like the more I spin the rod the looser it gets. I spun the motor over about 12 rotations and still got play in a rocker, so there has to be something I'm doing wrong in feeling for zero lash.

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  9 місяців тому +2

      Yes, I was lifting on the rod to see if the rocker moved, if it did, then I had more adjustment to make. The spinning is something, you've got to get a feel for. You can take up almost all of the travel out of the lifter and it will still spin freely, it's a very lite resistance, until you bottom out and have no where left to go. (something you want to avoid to prevent or you'll burn a valve from the valve not sealing completely during operation)
      The compressing of the lifter is where you make the preload adjustment after setting zero lash.
      As noted in the description below the video, set your preload according to the thread pitch of the studs.

    AWESOME VID ! Im changing out some leaky intake manifold gaskets on a Ford FE.. The rocker rail/roller rockers need to be removed because the pushrods run through the intake manifold. There is already oil in the motor and in the roller lifters. Can this method still be used on a motor that has already been started ,driven and ran? Can the oil in the roller lifters cause a valve to hang open once this method is used after new gaskets ,rocker rails, pushrods, roller rockers and intake are re installed ?

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  9 місяців тому

      If you are talking about the FE manufactured from 58 to 76, then no, this method will not work unless the rockers were changed out for adjustable rockers.
      Make sure to drain your coolant beforehand because there are coolant ports on the intake manifold.
      When you pull the bolts that hold the rocker shaft in place, there is going to be one on each side that is different. Take note to which hole it came from because it allows oil to flow to the top end. Put it in the wrong hole and the top end gets starved for oil. The shank of the bolt will be a smaller diameter than the rest of the bolts on the same side. Remember, there will be one on each side like this.
      Also keep all rockers and pushrods in the position that they come out of. They are now married.
      You will get some antifreeze out of the intake that will get away and flow down into block, but it will sink to the bottom of the oil in the pan and will come out first when draining the oil after repair.
      use a shop-vac while cleaning, to prevent debris from falling down into block.
      That intake will be very heavy compared to regular intakes.
      Good luck on your repair,
      Dave

      @diymisfit_Mechanic_UDX404  6 років тому +1

      I hope it works out for him. It's best to find out from lifter manufaturer how much preload they suggest on their lifter. On this engine, we are using 7/16 20 studs. So an additional 1/2 turn on nut will give me .025 of preload after zero lash. Stock rocker stud size on this engine was 3/8 24. Which would be .021 per half turn.

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  2 роки тому

      Yes, you can Collapse it. While you're tightening you could jiggle up and down until the play is gone. I just like to feel for the slightest resistance.
      If the lifters are dry, you can push the rod down into lifter to make sure you still have the travel available.

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  2 роки тому +1

      It's not the spring pressure that will collapse it when new, it would be from drawing down on the rocker nut to much.
      The valve spring doesn't come into play until you preload it.
      It is designed to do a partial collapse and the oil pressure will keep it tight. As things wear, it will require more oil in the lifter to accommodate for the wear to keep it tight.
      That is the hydraulic action.
      Solid lifters are better for performance, but require you to go back in and do manual adjustments, where the hydraulic is automatic, until something fails or wears out.

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  4 роки тому +1

      You are changing a rocker?
      To me, this can be tricky. I like them to be empty because I can feel the spring pressure inside the lifter. You can compress air, you cannot compress liquid.
      Because we used NSA rockers I could leave rocker loose and turn engine over and pump the lifter up fully with oil, then put cam lobe on the base circle, adjust to zero lash + additional preload. It's just not knowing if the lifter is empty, partially filled, or totally filled that bothers me, LOL.
      Or you could run the engine and set it while idling, tighten until tapping noise stops plus an additional 1/2 turn

      No, it will be fine, I just prefer to have them empty , so I can feel the travel in the piston of the lifter.
      Just remember when they are pre-primed, when you apply the preload, it will open the corresponding valve and hold it open until the lifter bleeds off the excess oil inside.

    If I've already set my lash and found someone set the cam timing 180° out with top dead center correct. Can I just remove the timing chain and rotate the cam gear and cam around until I get it at correct alignment? It seems I ran into something so I stop and didn't want to force it. But I was hoping it was spring pressure and I could continue on through it.

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  3 роки тому +2

      Once the lash is set, it is set. Turning the cam will have no affect on that.
      If you are working on a SBC, chances are it was put together right, just didn't turn the crank one full revolution before stabbing the distributor in.
      When assembling a SBC setting the cam and crank on the marks with timing chain, it is out by 180°, so before installing distributor, you have to turn the crank 360° to put #1 on compression stroke. When timing marks are lined up it is not on compression stroke.

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  3 роки тому +1

      Both timing marks should be at 12 o'clock for the rotor to be at #1.
      Unlike during assembly,(installing chain) cam is 6 and crank is 12.
      Hope this makes sense to you.

      No to both, turn down until you have just a very slight drag. it should still spin freely with no lash. After that you make your additional adjustment depending on thread pitch and how much pre-load is required. I like to do mine without soaking the lifters, because I don't want to risk the lifter chamber being full oil when setting pre-load. They get filled when I prime the oil system with drill.

      With this technique, you can start and end anywhere as long as you make at least 2 full revolutions of the Crank which in turn relates to 1 full turn of the cam. Be careful when lifters are not primed like I do, you can easily start pushing into the preload area without knowing. To be safe you can just use the jiggle method, don't worry about side play, just the up and down.

      To each their own. You can go either way. I did not soak them. I just gave them a quick submerge dip before installing turn.
      The lifters fill when I prime the system, before cranking. Once you have oil coming through every rocker, you're good.
      Oil has to go through the lifter to get to the rocker. If you are unable to get oil through some rockers, just rotate the engine a little and try again. At this point I still do not have plugs in the engine, so there is minimum pressure on any moving parts.

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  3 роки тому

      Yes, but some if not all lifters will be holding oil in them, I imagine you have hydraulic lifters. After you get to zero lash, the ones that are on the cam lobes will have more pressure when setting the preload. You will know when you feel it. BUT if you have a lifter that is collapsed or bottomed out, you could end up exceeding the pre load. Be very cautious when finding zero lash.
      Because you have already run the engine, I think it is best to go by cylinder like the manual suggest to make sure you are on a base circle, or you can set the valves while engine running, but you would need covers that have access to the rockers while running, to control the oil splash.

  • @pcrepairguys

    Every time I try this with used hydraulic roller lifters and roller rockers, I get a few valves that are open after 2 full revolutions. The lifters have been soaked in carb cleaner then left to dry for about a month. How do you fix that issue?

    • @diymisfit_Mechanic_UDX404
      @diymisfit_Mechanic_UDX404  4 роки тому +1

      When setting zero lash, keep twisting the push rod until you feel the SLIGHTEST bit of drag.
      Sounds like you are bottoming out the hydraulic portion of the lifter, leaving nothing left for for preload.
      There is about .060" usable for preload.
      You can also lift up and down on the push rod while tightening until you have no more lash.
      Once lash is gone then apply an additional half turn. That will put you approximately .030" of preload, depending on your rocker stud diameter and thread pitch.

      You will definitely feel the pressure when you go to set the preload with the ones that are on the lobe.

      As long as you are using a chevy style stud mount rocker on LT1 or older SBC or BBC. It will not work on LS.
      By making 1/4 turn increments while doing 2 full revolutions on crank, you will be making 8 stops on the cam. So you be guaranteed to hit the base circle a couple times throughout the process.

      They make a priming tool that you use with a drill. Some people have also modified an old distributor into a priming tool for user with a drill.
      But this was on a LT1, which required having the intake off to prime because of no distributor location on intake.
      It does sound like the lifters are not holding their fluid, or you have an oil supply problem too the lifter galley. When rebuilding did you make sure the check ball was in place above oil filter adapter housing. I'll see if I can find link for it.

      Sorry, I'm gonna say no. From what I can find is that engine has NON adjustable rockers.
      You would need a kit that converts the stock rockers to adjustable ones, and by replacing the bolts with studs

      @@James_the_Builder If your rockers are adjustable, (stud mounted - not pedestal mounted) then you are fine.
      If you are doing a 1/4 turn at a time with the crank, then you are making 8 stops on the cam. Remember there are two revolutions of the crank to one of the cam.
      So 8 stops stops should guarantee at least one stop was on a base circle.

      @@codered1691 are you sure you didn't drop the drop the distributor back in on TDC of exhaust stroke, instead of compression stroke. The TDC mark on balancer will be at pointer both times.
      The cam only makes one revolution to two revolutions of the crank.
      If you remove #1 plug and hold your finger over the hole, while turning the engine by hand, you will feel the high pressure building against your finger, then you know you're coming up on TDC of compression stroke.
      TDC at this point is when the dizzy gets dropped in with rotor resting on number 1 plug on cap.
      If you went too far with valve adjustment, the valves might not be seating, and you're not building enough compression.
      Use a compression test kit if you have one, and check all of your cylinders.

    If more people will use this simple 90 degree technique, they would not have as many problems with their valuetrain as they do. I think there's just been so many videos with people. Pulling out filler gages and all this other stuff. I think they're scared to try it. 0 lash is 0 lash all day long now on the preload. It's kinda to the individual but I would rather get the preload a little loose than I had to get it too tight. If I'm not sure about the technique i'using you can always go back. And Snug them up. But I've been using this technique for years, and I've never had a problem.

    For max power the only way to adjust valves is with the engine running. On hydraulic a small amount of tapper noise is desired. I tun in a quarter turn. The noise is gone and find reaction time to make more of a difference then a slight power loss. The engine has to be warmed up and running to adjust valves and achieve max power.
