      Yes I totally agree with you. When the engine is upside down is it? It is hard to keep track of the left and right side very difficult. Sometimes if you have to it may seem silly but take a punch and a hammer and mark it on the block or do something as simple as using. Maybe a little bit of spray paint. Maybe green for the left side and red for the right side or or whatever. Or maybe even a couple of pieces of tape or even some marks with a permanent marker. Whatever you got to do. I've had to make myself notes plenty of times so don't feel bad keep me up to date if you could on your your 360 how you're going to build it sounds like it'd be cool

    In '70, I bought a new AAR. Because the carbs were so lean, it burned a couple of valves. So I had it repaired, under warranty, at a Plymouth dealer in Lynnwood, Wa. Well, they completely butchered the repair. Long story short, they re-installed the shafts upside down and galled most of the rockers & shafts. The galled pieces damaged the cam, lifters, bearings, crank, and oil pump. So people pay attention. Simply not following explicit directions on how to install the rocker shafts correctly can have HUGE negative implications for any rocker shaft Mopar engine.

    Some replacement rocker shafts don't have the notch so you have to make sure that the oiling holes for the Rockers are properly located

    • @slantfish65sd
      @slantfish65sd  Рік тому

      First of all, thank you very much for watching the video. I really do seriously appreciate it. And these replacement rocker sheds you're talking about. I've never seen them and maybe that was something there for a while when people were using. Maybe the wrong wall or something I don't know but those rocker shafts are pretty thick material. They're not 10 material at all. Honestly it would take quite a bit to break one. They're really super thick so they're not made cheaply and I've never seen one broken. Maybe that was a just a regional thing and some certain region or something I don't know. And the replacement rocker shafts may have been gotten from a dealership that got them from some manufacturer who just grabbed up a piece of pipe that was the same size and said okay. Here we go! Here's our rocker shaft anyway. But yes, the oil holes do need to be lined up correctly. That's the reason why those notches in the ends of the rocker shafter there. But if the replacement rocker shift doesn't have them those notches. And yes, you do have to line up the oil holes correctly

    On the rockers you said there is no left and right rocker. Do you mean as far as left and right side head? I’m the video you point out that the rocker tip must be centered on the valve stem. And that the side by side rocker arms are stamped different such that if you install them in the wrong order they won’t be centered on the valve stem. Which would indicate there is an intake and exhaust rocker? But they will work on left or right heads the same? I’m learning. Just trying to make sure.

    • @slantfish65sd
      @slantfish65sd  18 днів тому

      Hey, Neil, first of all, I want to say, thank you very much for watching, and thank you for your comment. I would also like to say, don't overthink this. Okay, the main things you want to make sure of are that the valve stem tip is centered on the rocker arm tip, okay and the rocker arm. Has enough clearance for its movement throughout its entire travel. Same goes for the push rod. You want to make sure that push rod is not binding? It's not rubbing up against anything, do its entire travels. Also, you want to make sure that you have room for the other rock arm? That's right beside it to do the same thing. Okay. Furthermore, there is no left or right side head. They will interchange easily, so there are stamps and markings on the rock arms. However, these are not always consistent, and they're not always correct, so again. Focus on the valve tip being centered in the rocker arm tip. Movement of travel of the rock arm throughout its entire range. Make sure it's not rubbing or binding up against anything. Same goes for the push rod.
      Make sure that push rod is centered in its cup. In the rocker arm. Also, make sure that the rock arm wrap side. It has enough room for its travels as well. It's operation if you have any further questions, feel free to ask. I don't mind people asking questions when they are venturing into the world of mopars, and I have a lot of questions about this stuff. A lot of people look at the shaft rock arm system, like it's some sort of voodoo or black science for black arts or something.
      Believe me It's not that hard, it's not that complex. Don't overthink it, okay. Furthermore, let me also recommend if you don't have a service manual. Get one okay. I always keep you a good service manual. Around hell, even a haynes, service manual, they're not great, but they're better than nothing i talk about a lot of this in a lot of the videos, so anyway, all right, thank you again, and I'd love to see that engine running

    Can you change the cam in a Mopar 273 without taking the heads off and just removing the rocker arm assembly to pull the push rods and the lifters out of the way???

    • @slantfish65sd
      @slantfish65sd  5 місяців тому +1

      Hello Randall, I just saw your comment. I want to thank you for that and also thank you for watching. As to your comment, you do not have to remove the heads on an LA Mopar or a Magnum Mopar small block, which both of those are very closely related. So any of those 273 318 340 360 and yes, even the 239 V6 all of those do not have to have the heads removed in order to change out a cam. You do have to remove the intake manifold so remove the intake manifold. You can leave the distributor in place. You do not have to remove that either. Drain the coolant. Remove the intake, manifold and carburetor assembly and the lifters will be right there available to you. You will have to remove the valve covers and the rocker shafts and rock arm assemblies. Then you can remove the pushrods and then the lifters. Then of course you have to move everything on the front of the engine. All your water pump alternator, power steering pump, all of that stuff and timing cover if you have any further questions feel free to ask

    Video on how to set the rocker arms any suggestions

    • @slantfish65sd
      @slantfish65sd  2 місяці тому

      I have several videos on installing the rocker arms and all of the rocker shafts and push rods. There's really not much to it. Everybody wants to know how to adjust them and how to set them up and all of this really. It boils down to this. Check everything out, inspect it very carefully and thoroughly make sure everything's nice and clean. That way you're getting oil through it and make sure that is happening too. Because the Mopar engines they all threw the rocker shaft. They don't oil through the push rods. Also. Make sure that you have everything in line. Make sure that all of the rock arms are in their correct location. Make sure they are centered over the push rods and that the push rods aren't binding or scraping or rubbing up against anything like any part of the cylinder head. Also make sure that the rocker arm is in line with the valve tip. Okay this is very important. If they're not then you will have some problems and you probably will not get it fully assembled. If you have any further questions on this, feel free to ask, but you can search through my my channel and I've got several videos installing and setting up the rocker shafts and rocker arms

    Amazing Information when you read a book and get the proper shaft assembly correctly. Well here is my story, I have a 66 plymouth wagon that my beloved brother left me it has a 318 with a mild cam. A friend of ours built it when it was running the rockers chattered to much so he suggested some lash caps we put them on and they fell off pist man so pist so when i removed the steel valve covers there was milky oil on the valve covers so i went to check the dipstick and behold more milkshake any suggestions will help and thank you for the information on how to properly assemble the rocker shaft

    • @slantfish65sd

      First of all, thank you for watching the video and thank you for your comment as for your problem there with your engine. When you're getting that much milkshake in there, that means you're getting water in with the oil. Which you probably already knew that an easy way to determine where the water is getting in to the engine oil is drain. What's in the engine out? Leave the oil drain plug out. Do not put any oil in the engine. Fill the cooling system with water. Get yourself a coolant pressure tester pressurize the cooling system. There can be situations where the head gaskets will dry out and allow leaks. If the engine has been left to sit for an extended period of time, how much time it varies? Wildly when you pressureize the system without much water in it, see if the water is coming out of the oil pan. Drain plug hole and there are several possibilities could be leaking from where the intake meets. The cylinder heads could be leaking from the cylinder heads like the head gaskets, the heads, the intake or the block could be cracked if the water starts leaking immediately. As soon as you pour it into the radiator then most likely it's not a crack. There's a gasket somewhere that's just bad or and this is kind of remote you got. Intake doesn't fit correctly and there's a pretty wide gap between the intake manifold and the intake gasket ceiling surface as for the clattering with the valve train, there could be one or more lifters that have collapsed. There could also be improper assembly of the rocker shaft and rockers. There can also be a problem with the push rods. Not saying anything bad about your friend but if he hasn't assembled the engine correctly they push rods could be too short wrong length. They're going to be a bunch of different problems. If you can send me pictures or video of this I can probably give you a much closer answer as to what is going on with the engine but these two problems aren't necessarily related. Well, they're not supposed to be related. Let's just say that if you need to send me pictures or video you can do it here, but I'm also on Instagram as slantfish

    Is there a adjustment for rocker arms ? Bought a running 340. The rocker arms on exhaust valves are not preloaded at top dead center. Think it may have a bigger than stock cam. Please advise. Thanks Richie. 1970 duster 340 engine

    • @slantfish65sd
      @slantfish65sd  9 місяців тому

      Hey Mr. Pigpen, okay, just wanted to go ahead and say thank you so much for watching the video and thank you for your comments. Now let's get back to the engine you're going to. Need to pull off your rocker covers valve covers and see what kind of rock arms you have. If they are just like what's on the 360 that's in the video. Those are stamped steel and there is zero adjustment. Once you bolt them on that's it. The all the valve lash adjustment is up to the lifter itself now. If you aren't, if you don't have enough preload on that particular rocker arm could be that the oil pressure in that lifter or lifters in this case has bled down and that lash is now increased significantly when the oil pressure gets back up that last decreases. So that particular rocker system is totally non-adjustable now. However, I'm going to send you a picture of an adjustable small block rocker arm. If yours are like this then these can be adjusted and there is adjustment specs for them. I will give you those but I'm not going to. I'm pretty busy. Okay, I don't really have time to go through and give you all of those specs and the process on how to do them. Unless you actually really have those. So if there's any other questions feel free to ask. Like I said, see what you have first and then I will give you adjustment procedures on how to adjust them. Okay thank you very much

    • @slantfish65sd
      @slantfish65sd  9 місяців тому

      Okay, I don't really have a way of getting photos to you of different items. Very frustrating. Okay, I'll tell you what though the rock arms you saw in the video that you watched. Those are stamped steel. The rock arm I'm trying to send you a picture of is not stamp steel. It is cast like Ford steel like cast iron and it has an adjusting nut or adjusting screw on it. They're also known as ductile iron and so if you really want those pictures, you can find me on Instagram slantfish and I can share those pictures with you there

    • @slantfish65sd
      @slantfish65sd  9 місяців тому

      No way to really tell whether it has a larger than stock. Cam is to measure it with a dial indicator on like the rocker arm, the rock arm tip where it contacts the tip of the valve. Okay that's really the only way to tell and then compare those numbers to what is in a manual. The stock 340 cams were a little bit bigger than all the other cams for the 318s and 360s and 273s

    • @slantfish65sd
      @slantfish65sd  9 місяців тому

      Oh one more thing. The 340s came with hydraulic lifters flat tappet and so there is a special adjustment procedure for those. Again if you need that let me know. I have it in a manual. I'll be glad to copy that and send it to you

    I do have a question, your 318 is a rollercam LA, on both of my 360 rollercam LAs (91@92) they had the exact same lifters as a magnum, and they both had hollow pushrods.
    Both LA engines oiled through the block/head oil passage as well as through the pushrods. I noticed this while "pre oiling" by turning the oil pump with a drill. (And rotating the crank)
    Have you noticed if your 318 has hollow push rods, and oils through them as well?
    I really can't find any definitive info that I trust on this subject.
