    Default FE guys...need some advice

    On a solid roller FE motor, I have the lifter galleys plugged and running typical non-oiled pushrods, but we keep burning up the ends of some of the pushrods at the rocker. I'm changing to go to an oil-fed pushrod and my question is, do I just remove the plugs and let the loi flow to the lifters, or should I still restrict the oil some?
    TIA

    What brand lifters? Is the oil hole in the band or up from there?

    I going to assume you are using a lifter that was actually made for a 385 series. I have never seen an FE solid that sent oil to the pushrod.
    If they are, and they do sent oil to the PR, check to see if the feed hole is on the finished o.d. of the lifter, or in the waist band. They are almost always on the finished o.d. just above the waist band. Not much oil passes thru an edge orfice feed hole. You will loose more oil just from the same old leakage arouind the lifter than what goes up that hole. I would only restrict the supply if you are running fairly high RPM for extended periods with very little low rpm stuff. When you restrict the gallery, most of the oil thru the lifter gallery just bleeds past the lifter at low RPM, and you still risk burning the
    PR ends.

    Have you considered tool steel ends and adjusters.

    They're Morel Ultra Pros for the FE. They are not edge ofrificeted, they're basically straight through with no band.



    I can see the hole in the top...

    I have forgot more then I remember on these. I do remember doing the same thing 20-30 years ago. I did the restrictor thing and had the same problem. I removed them and had no more problem. But we did not have the roller lifters then. Same problem? Don't know. There are 2 blocks. If it had solids from the factory the oil galley was not drilled in the block and was if hydraulic. I might remember more later.

    IMO you have too much oil feed restriction in the heads. The reduced pressure and volume in the rockershaft isn't getting to the end rocker enough to splash oil at the cup. Try a larger metering orface. Also you might want to check the rocker to shaft clearance, too much will bleed off the oil to the end rocker.

    So... I'm going to ask so I do not say something stupid here... The hole goes all the way thru and is in line with the oil gallery? That large hole? There is a hole in the the bottom where the pushrod goes into this larger cross hole? I ask because of two resaons; 1) I am not familiar with the Morels as I have only used the Crowers on the FE and 2) Seems that if what I asked is the case, then you'd have a whole lot of oil going upstairs... like waaaay too much.

    Thanks 058. I understand what you're saying. I have .080 restrictors and I've been told those may be bigger than I need and might have excessive oil in the heads. The shaft assys are new and I had to hone the rockers to fit. They're about .0015-.002 if I remember.
    We're just going to restrict the lifter galleys to .100 and give it a try.

    I don't think there's a hole in the side of the lifters...only the ones front to rear.

    ETA...so I looked at a close up of another pic I have of the lifters and it looks like there is a small hole in the sides of the lifters.

    I followed and praised your awesome build/straightening of this motor. I have a 390 FE in my '67 Galaxie 500 convertible and have never been into one before.

    Along the lines of oil in the heads.....can you plumb in some better (external) returns to the pan? Like on some GM motors that need external plumbing to return excessive oil back to the bottom end? Then you could run whatever (or no) restriction?? Just a thought, but I may be way off base?

    I have to agree with both 058 and 6-oh-9. The shaft/rocker is a huge leak. To much restriction will starve the entire assembly enough to keep it from building pressure. Look back at the thread, I see they are buched rockers. I'd give it more oil to the shaft.

    Why? Because I agree with 6-oh-9. Those may be FE specific, but I bet they are just 385 lifters that haven't been drilled. I bet that hole goes nowhere. Never seen a lifter drilled straight down. And why would Morel send oil there. Where would it go?

    And last Steel, the very reason I went on the big oil hunt a couple years back was PR ends and adjusters, lifter bodies, and piston pins. I have zero issues now. None.
    Is he running what you told him to? Or is it something else.
    AND, if you look at M1's website, they do not recommend 10/30 as a repalcement for their 0/50 racing oil for use on the street, but rather 0/40. Interesting! What are they trying to tell you?

    LINK: Mobil 1 racing

    The 10/30 oil is approved as a ILSAC GF5 oil. Not a real inspiring approval to say the least.
    LINK: Mobil 1 10/30

    The 0/40 is not ILSAC approved. Mmmm
    LINK: Mobil 1 0/40

    And if you look at this sheet, you will see there is a oh so slight difference between the 0/40 and the 10/30. And this sheet is old and the 10/30 on it is a GF4 oil, not a GF5 that it is now. By the way, how many oil companies are posting a sheet like this on line?
    LINK: Mobil 1 product data sheet.

    Just some food for thought. Mobil 1 kicks ass, but sadly, they are not all create equal today. You know what I am running, and what Nelson is running. Not looking to start a big oil thread and go thru all that BS again. Its just a thought.

    If they are in fact for a FE, I would be very surprised they have a oil hole. And if for a 385, the hole would be on the side you see in the pic. If the hole was on the inboard side, it would no longer be an edge orfice. It would line up dead on with the oil galley in a 385.
    I am beginning to seriouly doubt flowing oil to the lifters is going to help you.

    Thanks Beer...you're not off base, but it sholdn't be necessary. The restriction is more to help keep oil on the mains.
