00:00Ready and go! As soon as we have oil coming up out of there we know the
00:04engine's charged. Now this is like you went into the grocery store and you come
00:07back out. Let's see what would happen. I just knew there was a way to fix this.
00:11Uno momento. It's a secret. I'm super excited about the second part of our
00:23video on the 6.7 power stroke oil issue. Now listen this is going to be so
00:28confusing to you. You'll be like oh what are they doing? You got to watch the
00:31first video first and that'll explain to you why I'm doing this testing and what
00:36we're doing here. So if you haven't done that go back and watch the first video
00:39first and then come watch this one. And what we're going to do here now is we've
00:46got this 6.7 power stroke. One of many that we're doing and let's talk about that.
00:52I've got a few comments, quite a few comments on this, hundreds of them and a
00:57lot of them are you know good how could they do this you know some of the
01:01questions I'm asking but a lot of guys are like oh there's no problem with that
01:05motor and I'm wondering how many motors have you rebuilt you know I do five to
01:10ten of these 6.7s a month and I'm finding a lot of spun main bearings a lot spun
01:19main bearings in the housing and the only way a main bearing spins is you know lack of
01:23lubrication it grabs the housing and spins the bearing around I mean that's
01:28it it's not rocket science and I'm seeing that cam bearings being torched out
01:34of them and same deal you know you grab a cam bearing it's because you didn't
01:39have lack of lubrication and the journal the cam journal grabbed the the babbit
01:43on the bearing and spun it into bore. So what we're going to do here this is a
01:47sim test machine what this sim test machine does is it spins up the motor
01:52different RPMs for testing before we actually install them in our vehicles
01:57it's not a dyno it's not a live hot run it's a cold run but it's going to be able
02:02to tell me what I need to know about what I'm about to test here so referring back
02:08to the old or the first video our issue is the extended flow of the oil before it
02:17actually gets to the main bearing and the rear cam journal to charge up the hollow
02:24cam and then charge all the bearings inside that cam. Before this camshaft gets
02:30any oil out of these holes it's got to charge through all that pipe system that
02:35I showed you in the first video it pumps up to this camshaft and this journal
02:40has got three little holes in it this is the journal that fills this whole camshaft
02:46these holes don't lubricate the cam bearings until all that oil flow has
02:52happened in the pan the oil cooler the oil filter housing up into the block and
02:58then fill this empty cam up. What we're about to do here is I want to see on a
03:05fresh oil change meaning we've got this motor totally drained now we filled up the
03:13oil filter so we have filled up the oil filter like it Jiffy Lube or something
03:18you know that's that's filled up the oil filter but but the pans been drained and
03:23now we filled it up and we're about to start it we're going to set this timer and
03:27here's where we'll know when we have oil finally up on the engine this is our
03:32hole that charges the turbo sits here so as soon as this is pressurized that tells
03:38me that my my camshaft and everything in there is full up and we're going to find
03:42out how long it is so I get a good stream of oil pumping out of that housing
03:47let's check it out okay I want to show you something here in the machine this is
03:52the oil pan now I'm pumping oil you can see it's pumping over the side there so
03:58I've got a constant flow of oil and the pickup tube is down in there so that's
04:02that's that's like I've just poured if an oil chain shop did this see how that's
04:08full up oil and it just keeps pumping and pumping it full but and I filled up
04:13the oil filter and I got a Ford Motorcraft oil filter on it so now we're going to
04:19crank this up like you were cranking the car to the truck to start it and we're
04:24going to wait and see how long it takes us to get here I'm going to tell him to
04:29hit the start button and we'll start spinning this motor and as soon as it
04:32starts to spin you're going to hear a beep it's going to it's going to wait a
04:37second but as soon as it starts to spin I'll hit the stopwatch we're waiting to
04:41see how fast oil comes up here all right go ahead and hit the start and there we go
04:52eight seconds okay so now what we've done is we simulated we let the motor sit
05:03all night and drain we're going to see is it any different if how long it takes to
05:08get oil up here to our telltale hold the turbo pedestal or is it the same as it
05:13was when an oil change I would think that it's going to be probably pretty close to
05:18the same but let's see and okay Joey go ahead and hit the start button and as
05:25soon as it starts spinning I'll hit the start here we go
05:38pretty dang close to the same I'm you know my thumb is it's seven eight seconds
05:44when this trucks has been sitting all night before I get oil pressure up to
05:48the turbo pedestal that's a long time now I'm going to check it right now with it
05:57only sitting for you know a couple minutes so now this is like you went into
06:02the grocery store and you come back out let's see what what happened so I'll hit
06:06it when it starts to spin so six and a half seconds this motor drains man these
06:25passages they just drain now we could do the math and here's the math I do we're
06:34spinning this thing at 500 rpm and it takes eight seconds how many revolutions
06:39of that crank has happened in seven eight seconds dry and the camshaft bearings I
06:46know they got a little bit of a film on there but remember that films being blown
06:50away if you watch my first video by a shot of air because we're we're draining
06:54all those piping systems out and we're filling them with air and whenever you
06:58introduce air into a hydraulic system it's you know it's being compressed and when
07:03it's finally released out of an orifice it it blows the oil out of the way not a
07:07good thing
07:08you know I feel like the Cheshire cat I got this grin on my face because I just
07:15knew there's a way to fix this and I think we found it so I've shown you in
07:20this video the second series of videos I've shown you what it how long it takes
07:26about eight seconds on an oil change with a full oil filter I don't even want to try
07:31this since I'm building this motor for a customer with a full oil filter and then
07:37cranking on how long does it take for the oil to get up to the turbo pedestal
07:41which basically is telling me the rest of the motor is charged with the oil it's
07:45eight seconds and then what we did is we just turned it off for a moment for
07:50about I think it was less than an hour like going in to go grocery shopping or
07:55something like come out again and then start it it was it was basically seven
08:00seconds I mean it didn't really make that much of a difference so I've done I've
08:06installed a little fitting that I have designed in the motor and I'm going to
08:13crank on it now it's been sitting and I want to see it now how long does it take
08:19to get oil pressure up to my turbo pedestal because I'm what I'm trying to
08:25fix here is all that passageway that I showed you in the first video all that
08:30oil draining out of that motor I don't think it's a good thing because like I
08:34said I'm finding a ton of spun bearings main bearings I'm not finding rod bearings
08:39main bearings spun in these motors so let's crank this up hit our stopwatch and
08:46see what we got okay so we're gonna hit the start button and as soon as the
08:51engine starts to spin you'll hear a beep beep beep again before it actually
08:54starts spinning I'll hit this timer we'll see how many seconds it is now as soon as
09:10it started it didn't lose any oil pressure but it didn't really build the
09:14pressure till four seconds let's just try it again I'm going to reset it
09:27let me see we got oil already and as soon as I think it sucks yeah I'm not hitting on my button as good as I am but you can see that I haven't lost I'm not draining the oil out of this motor you can see
09:44see as soon as this thing starts to spin I'm not draining it it takes a second or
09:49two for it gets up to speed like it did on the other but I mean BAM I got oil right
09:52there
09:55I'm turning that motor less than 150 rpm and I've got buco amounts of oil in there
10:04it's it's not draining out now any smart guy out there or gal probably figured out
10:13what I did and I'm thinking for 50 bucks and maybe the manufacturer ought to think
10:23about that I don't know but we got a fix for it and every motor I build in every
10:29monster engine I build that's a division of Dave's Auto Center my son started that
10:35business we'll be doing this little trick in every one of our motors and I'll bet
10:41you my motors last a whole lot longer than the manufacturers long block just for
10:49this one simple reason
10:52what we're doing here is we're going to pull this pan off
11:03what I think it seems serious okay it's a secret the moral of this story is this is what engine
11:32builders do this is going to happen a good engine builder is always going to
11:37find a way to make it better that's that's why I do this this is exactly why
11:43we do this every motor has an opportunity to make it a little better
11:47that's our job that's not what you like doing you're not a motor builder do
