    The LS Chevy has a nearly identical oiling system. People used the wrong lifters causing excessive top end oil. I ran a 400 over 200,000 miles with 10PSI oil pressure idling and 35 on the highway in a 6600 lbs truck. Didnt even have to overbore it, just new pistons and rings. Same cam too with .525 lift. The drainback holes flow more oil than you can pour it in with a gallon jug. I've even ran it 3 qts low without damage. Machine work and assembly prevent all the "problems" with Cleveland oiling systems. Tim Meyer has a very effective "fix" for the block that works well if they scare you.
    The Boss motors and the old M/T valve covers have stubs on the top of the covers roof to concentrate oil and drip it onto the springs. These heads were run in NASCAR without all the fixes.
    Port the internal passages of the oul system and the pump and you'll pick up about 15 to 25 PSI of pressure and don't use a HV pump.

    My brother had a 400, 4V quench heads, single plane 4V intake, crane commander cam, headers, stock pistons, high volume oil pump.
    We had so much problems with oil pressure going away with any rpm.... and our fix was 2 extra quarts of oil and a re marked oil stick as shown. Lol

    •  3 หลายเดือนก่อน +1

      That's one of the common mistakes people make with Clevelands. They don't need a high volume pump unless you're turning 8000 RPM and if you do use one, you absolutely have to use a deep pan with at least a 7-8 quart capacity.. If you don't, then you get just what you experienced: Oil starvation because it sucks the pan dry.

    Fantastic video, extremely valuable information. As you say at the end there are other problems with cleveland oiling, but this one of the best practical demonstrations I've seen for this.
    This is the basis that all the reconciliations to not run a hi volume pump are based around. I don't actually subscribe to that theory myself, but without other mods it holds true. It causes this to happen faster because it overwhelms the drain backs quicker.

    Odd the LS oiling system is not much different from the 351C yet the GM lovers think its the best motor on the planet. We had no bearing problems on a 351 C with the hi pressure spring on most and with lifter bushings on a few back in the day. You make a interesting point on the drain back problem. I thing correcting this would probably cure a lot of problems.

      Like every Cleveland I ever saw, mine had the same problem of the lifter pushrod sockets wore out due to normal lifter rotation and starved the rocker arms. Anyway, my lifters weren't sloppy in their bores, they were a bit challenging to remove due to a slight varnish ring had formed around the bottom edge of the lifters.
      I keep the sump slightly overfilled, minimum of 5qts and run 10w-40 or 10w-30, not 40w-90 like some people claim.

None of these stopped my problem. ii installed Denny Wendorff's Lifter bore bushings and have run at 7500 RPM with out a problem. I have been running Cleveland's since 1970 and have this engine engines that has a problem and others that don't!

    This video has more sensible info than most I've seen. I never knew a Clevo could hold that much oil in the heads. I am genuinely surprised.
    I am planning on building a couple of Clevelands in the not to distant future and have been collecting bits for it for a while now. The first thing I purchased was two High volume sumps with proper baffling and windage trays to get that 7 lt capacity off the bat. I think the engineers got it wrong in the initial design which would explain the premature wear of these engines back in the day.
    They usually need reconditioning after 120K. Now we know why.

    Restrictors in the right place increase pressure, a good thing. What is the Cleveland's difficultly is the crankshaft, I can't remember which journal maybe mains #3 to rod # 5? Which ever it is when the shaft spins it blocks off oil to the rod bearing which under duress causes problems. After market cranks correct this and grooved bearings help.

    @douglaspage2398 9 หลายเดือนก่อน +1

    All factory engines have "oiling problems" when used in racing application when they are not factory racing engines. When you increase engine RPM you have to uncrease oil capacity to keep your rngine from outrunning your iol supply, ehich is why there are high capacity oil pans available, and some need higher oil pressure, which is why high volume oil pumps are available. And it goes much like that with every modification you make to add power, torque, acceleration or speed, such as stiffer valve springs for high rpm cams, porting or afternarket heads for the increased demand for flow. Etc.
    This is simply what separates the parts changers from the mechanics, the mechanics from the engineers, those from the racing mechanics and racing engineers.

    @larrybralley1942 10 หลายเดือนก่อน +1

    So, when you change the oil, there are roughly three quarts of dirty oil remaining in the heads? Seems if it was initially filled with 7 or 8 quarts, it would always have an adequate amount of oil in the sump, and wouldn’t need a larger one. In other words, the amount that doesn’t drain back would act as a reservoir. Seems that too deep of oil in the heads would cause the Cleveland to smoke, getting under the umbrella seals and through the guides. Maybe I’m missing something or misunderstanding the video.

    • @crd-nz_001
      @crd-nz_001  10 หลายเดือนก่อน +1

      The drain backs to the head are both too small and on a sharp angle. This design is to slow the flow of oil at elevated rpm. Under normal driving conditions, the drainback is able to keep up. It's not until the engine is held under high rpm that the flow of oil going through the pushrods to the valvetrain overwhelms the drainbacks, causing the oil level in the heads to rise until it escapes from the pushrod holes. It is designed this way to protect the valvesprings from overheating as once spring steel is heated to a couple of hundred degrees, it loses its spring strength. Results of this are valvesprings that can no longer control a valve (valve float) to broken valvesprings.
      This demonstration shows how much oil is held in the cylinder heads versus how much is recommended to be in the pan.
      In short, a larger capacity sump cures most Cleveland Oiling problems. No restrictor kits, external lines, or machine work on the lifter bores are ever going to cure oil starvation caused by an engine that puts all its oil under the rocker covers and leaves none in the pan!

      @danielwilson6665 5 หลายเดือนก่อน

      @@hoedemakerbartThe oil gallery problem you mentioned isn’t really a problem. Most V-8 engines from that era did typically use 3 gallery’s for oil distribution. The early Cleveland prototype designs had 3. But the bean counters at Ford insisted that using only 2 gallery’s would reduce the overall amount of machining required to prepare the block for service. That was supposed to cut the labor costs per block. I suppose when producing thousands of blocks the cost saved would really add up.
      But financial geeks that are only concerned about cutting costs don’t have a clue about actual performance requirements.
      Obviously they got what they wanted and the design engineers didn’t.
      Now I’m sure the guy on this site talking about excessive oil in the valve covers and over filling the stock oil pan with 2 more quarts as a fix, probably has good intentions. But in my 42 years of Cleveland experience I’ve never heard of such bullshit. I agree with your plan to upgrade with solid roller lifters and installing lifter bore bushings. It works great for me.
      The bushings do cost more but understanding the benefits they provide will easily justify the cost. Those 2 oil galleries that run the length of the lifter valley, also intersects each lifter bore. The size of the hole where they intersect is huge. If you’ve ever seen what happens when the oil pump is turned and pressurizes the block with a lifter removed from its bore you will understand my point. Oil gushes from the bore like a big internal oil leak. Way more oil than is required for the original hydraulic lifters. Solid lifters need even less.
      I don’t have a clue why it was designed that way but a bushing with a small orifice to properly meter the oil supply to the lifters takes care of the problem.
      I certainly don’t qualify as an expert but I have studied the oil supply design enough to understand the potential problems. I doubt that these internet experts have ever seen the oiling diagram. Many blocks have priority oiling to the main bearings before the valve train. Clevelands oil the right side gallery and valve train first before oil is delivered down to the main bearings. Reducing the amount of oil wasted to the lifters will naturally provide more to the mains. It’s not rocket science, just common sense. You understand the problem so you should be good to go 🏁.

      ⁠@@hoedemakerbart A dry sump system isn’t necessary for most performance builds. If turning 6000 rpm’s or more for long periods of time then the dry sump would make sense, despite the high cost. For most applications any good aftermarket pan is fine. I use the Milodon 30927 low profile front sump pan. It has baffles for good oil control and a 8 quart capacity. It also has enough internal clearance for a 4.100” stroker crank and the gold finish looks pretty good on my black block. The Milodon 32220 windage tray fits well with no interference from the 4-bolt main caps. The guy insisting that adding a few more quarts to the stock pan will solve oil supply problems doesn’t know the problems caused by moving the oil that close to the spinning crankshaft. excess oil on the crank stealing horsepower, crank throws whipping the oil into bubbly foam that the pump can’t move and the increased oil temperatures because it’s too close to the hot rotating assembly.
      It’s just a bad idea. A deep sump pan will also add more capacity while moving it away from the crank.
      Just keep in mind these are my opinions. And opinions are like assholes, everybody has one and they all stink 🤮🤮🤮🙂

      Yes. It was a design based on a Pontiac (a handful of parts are interchangeable), but also uses other GM design cues to make the best engine possible for the time. First sold in 1968, the majority of parts were indigenous to Australia and unique to Holden. Which means very little of anything else fits. It remained Holden staple V8 until they switched to Gen 3 LS V8s in the early 2000s.

      The drain backs are small, which restricts oil flow from returning to the sump. This protects the valvesprings from overheating and failing.
      The test shows how much oil can be held in the rocker covers, which inevitably starves the oil pump, causing bearing failure.
