00:00Bad engineering. Bad engineering. This is nuts. Here's what air does to it.
00:06Somebody's got a problem here. I got a fix.
00:11Hey, good morning, everybody. Before I show you the video I'm about to show you, I wanted to talk to you about something.
00:16I'm an engine builder, and what that means to me is building engines, obviously, but it means building them better than they were already built.
00:26I'm not an engine builder. I'm just a parts hanger. I'm just a guy that takes stuff apart and puts it back together.
00:32That's a good start. We all start there, but after 34 years in my own shop, almost 50 years of doing this, I want to make a better product.
00:45And so a lot of you out there are saying, my goodness, there's problems here, there's problems there. There's problems everywhere.
00:57And a guy I follow, Steve Morris, is an engine builder, and he builds blown motors that blow your mind.
01:06And he doesn't build everything that I build. He's very specific, and he's a lot smarter than I am.
01:13But I follow him because what I like about him is he just wants to find better and better and better.
01:19That's the best way I can explain it. And that's what I do as an engine builder.
01:22So the video I'm about to show you is going to talk about a 6.7 Power Stroke and some of the issues that we're having.
01:28Spun main bearings, lost oil pressure in the camshaft, and some of my reasoning for that and some of the fixes that I think should happen.
01:38Every engine I build, every engine I build, I'm built this way. I want to find a better way to do it.
01:45So I'm looking for the failure points in them. And every engine, Ford, GM, Toyota, every engine has failure points.
01:54For good engine builders, we want to fix those.
01:57I'm going to find some things out here, and it's not pretty. It's kind of like you just want to slap some people and go, what were you thinking?
02:04So let me talk about this.
02:06This is the oil pan off of a 6.7. It's obviously cleaned and a lot better.
02:11Here's a block, and I'm going to walk you through here some of my concerns, and we're going to figure out the truth about this.
02:19This pickup tube, I'm just curious. Oh my goodness. This thing is a full-on inch and a quarter pipe.
02:31So first thing I want to find out is, how much oil does that thing hold? Because here's the first thing that I've got issues with.
02:39So this is down, this pickup tube is down in the pan, and of course, this is where our sump sits, and this is where all the oil,
02:49I think these things take 12 quarts of oil or something like that. This is basically where all the oil sits.
02:54That oil does not come up higher than this in the pan. It doesn't.
02:59So now we've got to fill all this up. Then it comes to here, which is the inlet side of the oil pump.
03:12And then the oil pump pumps it up. This is the front of the engine, the crankshaft.
03:16The oil pump pumps it up, then it pressurizes it. Now it's pressurized, and it pushes it down through here,
03:22runs through this tube, all the way down through here, and comes out right here, into the—I've taped this up
03:33because this customer wants a purple oil pan. It comes out, feeds through the oil cooler here,
03:39and then goes back into the pan here, crosses the pan inside this tube here to the other side.
03:47This is where the oil filter housing bolts to. Feeds the oil filter, goes through the oil filter,
03:56back into the engine, and comes up this tube here. And that hole there is right—let me show you where
04:07it's at here—that hole there is right here. So that hole in the pan here sits
04:16right there, okay? So now we're going to take—we're going to take some measurements here,
04:25we're going to figure some stuff out. Get this right—there it is, right there, like that, okay?
04:31So this engine's upside down. Here's my question. How much freaking oil is in all these holes in
04:39these tubes that drains out of the motor before it gets into the motor to the bearings?
04:48I'm going to take this gallon water jug and I'm going to start filling this stuff up. I'm going to
04:53do a little experiment because it's a concern to me. You know, my guess is there's two quarts of oil in
04:59here. So we're going to fill this stuff up with just some water and take a measurement and find out
05:04how much oil are we draining out of this thing before this engine charges up. Okay, here's an old
05:10bore brush that we use to clean out these bores and stuff. So we're going to just kind of like look
05:14here. So now—so the oil gets pressurized down through this hole. And if you look here, this is
05:23galley. Now we've pulled these plugs out of here because we brush motors, you know, we clean all this
05:27out. But then the oil comes through here, goes up through here. This is the cam. Now I want to show
05:35you something about the camshaft on this motor. Now this camshaft is wiped out a lobe on here,
05:41but so this is junk. But this is the camshaft out of a 6.7. So now the oil comes, the oil comes,
05:49pushes, gets pushed here through this oil port, goes through the engine. Now it comes,
05:56it comes, it's charged, it charges this main up and this rear, the oil here goes to this,
06:04this is the cam bearing, the rear cam bearing. That rear cam bearing goes right here in this journal.
06:09Now look at the little hole. Here's a hole. There's one right there. Look, there's another hole,
06:17another hole. These are bearing journals on this cam. This is what's like, I don't get it. You look in this
06:24block. Now everybody that builds motors, you're going to know, normally the mains would oil the
06:30cam board. You just, they would have gun drilled this, this journal right here to where the cam bearing
06:37goes. I've got the bearings out of it, but this is the, that's the housing that would house the bearing
06:41journal. All of them in here. Not this motor. I guess they thought it was smart enough that we're
06:47going to, we're going to lube every cam journal on that motor through this port by having that,
06:55that the camshaft is hollow. So now I got to fill up this hollow camshaft. I can pull this. I'm going
07:01to pull that. I'm going to pull that plug out of there and we're going to, we're going to fill
07:04this camshaft up. We're going to find out how much oil that holds before this engine sees lubrication
07:11on the bearing journals. That's what I'm after here. I want to know how oil starved this engine really
07:18is on a cold startup. And that's what we're going to do. Okay. So here's a brand new cam
07:22that we're, that we're going to put in a six, seven. It's a performance cam, an upgrade stage one.
07:30They don't come with oil plugs, but you can see how big the hole is in there. So I'm going to tape
07:36up all these holes here, just some tape. I'm going to wrap them up and we're going to pour water in
07:40here. We're going to find out what our volume is in this cam, what our volume is of oil in the pan
07:47and everything like that. I just need to cover the holes is all I don't need.
08:07We'll start filling this and we'll keep track of how much we got.
08:09That's how much the camshaft takes.
08:18Okay. Now we're going to fill up the oil cooler.
08:27Now this is the oil part of the oil cooler. This is where the cooling goes. So we're going to set
08:31this here and this will take a little longer to fill because it'll want to
08:38whoop, whoop, whoop. Trying to be accurate here. It's about topping that off.
08:44So that's the oil cooler. Now this is your oil filter. Now this isn't going to fill up the way
08:49I'd like it to, but we're going to just tell you, I mean, this is an old oil filter,
08:55but that's at least a quart. I mean, and guys, this is important. Most people aren't out there
09:03changing their oil. They're going to Jiffy Lube or, you know, their tire store or whoever.
09:07And man, you better hope the guy that's changing your oil takes the time to let this oil filter
09:12fill up with oil and doesn't just screw on one without oil in it. Everybody knows you should fill
09:18up your oil filter, your new one when you change it, with oil so that you're not pumping air through
09:23this thing. But let's just kind of see how much we can get in there.
09:30Okay, so we're done there.
09:36Okay, now I'm really not going to worry too much about filling up these these galleys in the block.
09:42You know, we could we can make some assumptions that maybe there's a quarter of a quart in there.
09:47But let's let's do this one now. Joey, hold this for me.
09:53Okay, so now dump it out. Oh, shit, that's a lot of.
10:05Okay, I think we got it.
10:09Okay. All right.
10:24And what we haven't got here yet is the oil pump housing that would sit here. The oil pump
10:31is going to drain. But we've definitely got a half a gallon, two quarts. I was kind of thinking
10:39two, two and a half quarts. So I was pretty close. Yeah, everybody get bad engineering, bad engineering.
10:48This is nuts. You expect this motor to survive after an oil change when you drain all that out of there.
10:54And also when it sits for a while. I don't know. But we're going to find out how long it takes to get
11:01oil pressure up to our bearings. Let me show you what air does up against oil. Oil. You want that on
11:08the bearing surface. Here's what air does to it. Pushes it right out of the way. You don't have any oil up
11:16against your bearing. It's insanity. Somebody's got a problem here. So this is the power stroke. This is
11:24how they're, so they've got these oil tubes sitting over the rockers. Now a lot of people don't know on
11:30this engine, they have got push rods for every valve. That's why there's just a ton of push rods in
11:40here. And those push rods go down to a lifter that looks like this. And in that lifter, there's two
11:46this is the roller, the housing for it. And it's got two of these little lash adjusters. And those
11:52lash adjusters sit at the bottom of these push rods. Now everybody knows this motor is famous.
12:00You read on the internet. There's so many people complaining, hey man, I changed my oil.
12:04And the thing just clatters forever. After I have my oil changed, it clatters on startup and it doesn't
12:11go away. It takes a while. This is why it doesn't go away. Remember the air and the oil?
12:15Whenever you introduce air into a hydraulic system, which is what oil pressure is, a hydraulic system,
12:22you're basically collapsing all these lifters. And that's what the clatter is.
12:28And Ford has got a problem with this. And the other problem that I see in their lifters are,
12:37and I never liked these kind of lifters, you can see there's little needle bearings in there.
12:41See those little needle bearings? Now you go to a roller racing lifter, they ain't got no needle
12:49bearings in that thing. Because I'm going to show you here on a piece of paper why. Here's a lifter
12:54that's failing. The pin is actually coming out of the lifter. And it's starting to fail. When that fails,
13:03you're going to grenade your motor. But let me show you why needle bearings are not the way to go on
13:10heavy spring pressure. So if ever you do any performance work, you want to get away from
13:15this. Heavy spring pressure, you want to get away from this. And let me show you.
13:18I want to talk about the problem I have with needle bearings in a lifter. And the best way I can do
13:27that I think is to show you something. So let me draw this out. I'll just use this. I'm not a good
13:33drawer. So I'm going to draw a half circle on that. And then I'm going to draw an outer ring like this.
13:44Okay. Our needle bearings are inside that lifter like this. And they're all the way around there.
13:56Now my point is, and a bushing is different. I'll show you how that works. My point is, is how much
14:02load is distributed on those little points of where the needle bearings touch the inner shaft and the
14:08outer shaft of that roller lifter. And that roller is turning on this. It's better. It's proven
14:14better. That's why racers do it. We put a bushing in here and it's solid. A bushing is solid.
14:23And so we have an oil film running here and an oil film running here. And we distribute the load
14:28much better that way. So a bushing all the way around in here, and this is solid like a bronze
14:33bushing. This is solid. You just get a little oil film in there, a thousandth of an inch. And it
14:40lasts takes a load better and it lasts a lot longer. So that's one of the things we want to look at for
14:45this oil. You know, the lack of lubrication, we want to try to figure out how we can best
14:53not have an issue with that. I've got a six, seven built ready to go in a truck. And I want to show
14:59you a few things. Somebody had said to me, what's all the blue tape for? We do that for safety. And look
15:05here, any opening. See, we put an exhaust manifold on this side. We haven't done it on this side. We
15:11do that because, yes, it's true. We have put motors in vehicles before where we've dropped a little nut
15:18or something inside. One of these intakes or exhaust port and it's gone through the motor. We, you know,
15:25we have done that. And a simple thing like tape on there will keep that anything from falling in there
15:30until you're ready to put the component on there. Just a little tip. But come over here. I want to
15:35show you something. And we're going to do this test to prove my point about how much oil. This is where
15:39the turbo sits on this pedestal. And I believe one of these holes is coolant and the other is oil. I
15:46think this is the oil one here, but we're going to, we're going to find out which one. And we're going to,
15:52and this is my, this is my contention. I'm going to start the motor up in my sim test machine. And that'll
15:58be another video that I'm going to show you. It'll take me about a week, but I'm going to put this
16:03engine on my sim test machine without the fix in it, without the fix. And I want to see how long it
16:11takes before I charge this engine up. Like we've talked about, it's two quarts low when it drains out.
16:17How long does it take before I see oil up here? And this oil hole right here gets its oil pressure
16:24from the lifter galley. The lifters are right here. So I've got to, I've got to charge my main
16:28bearings. I've got to charge my hollow camshaft. I charge my lifters and then the turbo gets oil
16:34pressure here. And we want to time. How long does that take? I don't know, but we're going to find
16:39out. What I'm going to do is I'm going to take that six, seven back there. I'm going to put it in
16:43my sim test machine. I'm going to run this thing up to 500 RPM. That's about cranking speed when the,
16:51when the engine's starting and I'm going to see how fast I get oil pressure in there. That video,
16:59me testing it without my fix and with my fix, will be in about a week.
17:07And follow me and we'll, we'll have that ready for you. Thanks.
