long story short I don't know if I've danced this but I was pulling a trailer back from
a city far away and lost a cylinder and we're pretty sure a piston came apart and we're
pretty pretty sure it's related to the displacement on demand active fuel management gimmick that
GM makes in their trucks that supposedly saves you fuel which is about probably half a mile
of a gallon at most but destroys engines and due to certain situations in the world this
engine's a 6-2 liter and it's non-existent it's a unicorn they don't have any blocks
out there I took it to a dealer they can't get a block and used blocks are going for
like six to ten thousand dollars because they're so rare the guys are selling their hundred
thousand mile salvaged trucks for a ton so we're going to pull the engine we're going
to take a closer look and see how bad it is if the block is salvageable because that's
the part that GM does not have is locks they just I don't know GM shame on you anyways
we're gonna take this engine out take it apart find out what's wrong and then hopefully I
can have the cylinder board new Pistons put in and rebuild this thing with a deleted DOD
so there is no DOD different cam different lifters and everything and have a six two
that's hopefully bulletproof it'll last hopefully more than 140 000 Miles because that's what
this one got so you guys want to go for a ride we're in the middle of harvest but it
rained and it's gonna rain for the next couple days so the stash is ready let's tear this
thing apart
number one cylinder is the one that failed have not done a compression test but the spark
plug came out it was missing half the tip of it and we scoped the cylinder and it doesn't
look good so let's just hope that it's okay and the block is salvageable because if it
is I can have a truck running again if it isn't this pickup won't be driving for at
least a year because that's what they're saying how far out the blocks are at least a year
why does it say don't touch is it only if um when it started could you touch um it's
just saying be careful because there's a fan here that spins really fast and it can hurt
your fingers if you're touching there when it's running okay yeah are you guys gonna
help me yeah best helpers around fun well I guess we'll just time lapse this and just
start the process of disassembling everything to get in there to get that out wow this is
a long time yeah tell me about it Daddy I'll look in here I must ask you a question what
you guys like mustaches
all right front end's all off the most part I gotta take the radiator cooler and this
whole part off but it's funny I took the skid plate off and look I was sitting in that skid
plate wonder how long has been riding in there every time you lose tools I drop down inside
you can never find them they're probably sitting on your skid plate I'll add that to my collection
worst part about doing this job because I know for a fact there's no way I'll get this
together as tight as it was when it came off plastic brittle tabs you guys know what it's
like
[Applause]
all right update okay so um got a lot of parts over there a lot of tools they keep adding
up I don't know why it just keeps getting more tools like you think you got enough and
then you gotta get another tool uh I've been watching that Sunday Drive on YouTube and
he's got a really detailed video on how to pull a five three or a six two the only thing
I haven't done which I I'm gonna wait and see if we can get away with that but I will
probably have to is kind of pull the dampener off the front that front pulley there to get
enough room for it to graze by this radio otherwise I gotta pull the radiator and hopefully
I'll be enough room for this engine to come out but anyways I think I've got it ready
to pull it hasn't separated from the transmission yet I hear that's a bear so I'm waiting for
the guys to have some hands on that because it's gonna take a few hands to Jack pull twist
pry chisel to get that to separate there's dowels on that transmission that lock into
the bell housing of the engine so we're close we're really close I'm really excited to get
this out I'll tell you what this has not been an enjoyable job this isn't really my cup
of tea I can do it but I don't enjoy it I just there's so many wires and so many connectors
and hoses and grounds and I've broken so many electro connectors so many I don't know how
I'm gonna have to glue them all back on I don't know why I'm terrified anyways with
all that said there may be an engine out there someone found a reman possibly I could have
in a couple weeks so we'll see if we get that way if not I'm still going to try to rebuild
this one but we're this close so next step is wait for the guys and then we'll hook the
Hoist on and start the process of pulling this thing out fun fun and then I'll pull
the heads off and show you guys the Carnage it's gonna be great I gotta shut this thing
off I just I don't like it it's coming off three days it's all all right got the guys
let's pull this into now we'll make it happen [Music]
foreign
put all the random parts and stuff in the truck that can sit outside because it can
probably be parked for a while and I just thought you know what let's just start peeling
her apart so I got the valve cover off I've got almost all the head bolts out there's
one left right here and I'm working on it right now this is the cylinder number one
that's the bad boy the one that definitely had a problem and it's uh oilier than the
rest in the exhaust port clearly something's going on at that cylinder so we're about to
find out let's finish pulling it off
all right she's loose you ready to see the damage all right here we go
something what am I catching on one of the head bolts is about all the way
[Music] [Applause] okay all right let's try it again
there we go got a bad push rod okay my suspicion has been confirmed
Piston's missing a piece right there and then we got a bad push rod look at that I guess
that happened I guarantee you it had something to do with a lifter
gotta be why else would this push rod Bend AFM active fuel management displacement on
demand DOD biggest joke on the planet I can't tell you how many engines five threes six
O's six twos for like 10 plus years have been destroyed prematurely because of this system
all to save like a half a gallon a mile a gas you lose power you lose efficiency with
your performance and this happens the lifters fail and then it crushes the push rod and
then your spear valves slap your Pistons I see some marks on this piston where I think
the valve has been hitting it and then other reason why my Pistons probably broke is because
when those cylinders are deactivated carbon builds up these engines are notorious for
carbon buildup they're direct injection and there's a lot of carbo if the Piston's not
firing there's nothing in there to burn the oil residue that's in there the cylinders
still have oil in them when they're not running so once up happening is those cylinders that
deactivate the piston rings which have to expand and contract due to heat they have
to move freely gets carbon buildup around the piston and the Rings it ends up happening
is those rings gets solid and they can't contract like they should when the engine warms up
or expand and so it blows out part of your piston and that's what happened to mine now
bright side I haven't turned the engine over to see what the cylinder wall looks like but
this is not that bad this cylinder wall probably can be honed out we'll take a look at it for
sure but it's not like a catastrophic rods bent chunk out of your head's gone this is
repairable so so far I'm pretty happy with what I'm seeing the head on the other hand
we'll look at that in a second that might need replaced I don't know if that can be
fixed we'll look at it right now okay here's head number one actually
so it doesn't look beat up the spark plug definitely has got problems but I don't see
any cracks I'll have those heads taken into a machine shop they'll check them make sure
they're still true that the heads are good and the block can be fixed I'm back in business
I'm gonna get all new Pistons do bearings across the whole bottom of it new DOD none
deleted where you want to call it camshaft with better lifters new push rods a couple
Grand in a lot of time putting it back together and putting it back in the truck and then
I'm at my own risk of it failing because there'll be no warranty on this but hopefully we'll
have a high performance 6.2 that'll last 200 000 miles plus
cool I'm excited I'm really sad I'm really disappointed to be in this situation this
is really terrible you know you buy a pickup and use it for a year and then it blows up
on you but that's life and the fact is this is repairable so let's get to it and I know
a lot of you guys are probably looking right now for an engine for me believe me I've caught
a lot of dealers and they found one one 162 reman sitting in South Dakota and it's already
spoken for and the dealer took six months to get it or maybe it was eight and their
customer wants it patented I don't blame them so hopefully they get in there's that customer's
truck and get it running so with that said yeah they're a unicorn of an engine right
now so GM's got some manufacturing issues going on right now and hopefully they can
get caught up because blocks are scarce let's turn it over and see what it looks like inside
I'm really curious about that let's see here where's a good bar right there there's a breaker
bar put my 24 millimeter on here I'm getting good at this millimeter stuff getting a lot
more millimeter metric equipment on the farm all right here we go
all the bottom almost to the bottom
there we go that's bottom okay let's take another look here we go round three oh yeah
just right there on the top that's damaged overall um I think I'll have to have a machinist
look at it I'm no expert I think that could be honed out if it can't be honed out they
supposedly can sleeve these so we'll find out but if that's just a honing job oh yeah
now granted there could be problems in the other four too but as far as I know those
are running great there's nothing unusual in the ports I think that side's good I'm
pretty sure this doesn't want to failed that's one that threw the code enough talk okay now
it's probably going to be a while till the next part so this video is going to be delayed
a little bit so stash will probably be gone a beer will probably be back I'll probably
have gray hair I already do maybe gain 30 pounds because it's got to go to a machine
shop get all this figured out but when it does we'll pick up where we left off just
getting back out to the field so I had to drop off those engines that's the five nine
Cummins out of the famines and my 6-2 Ecotec 3 out of my 2015 Sierra at the automotive
shops to get work done so they're gonna try to see if they can find parts they can find
parts they can rebuild both of them that's what they said so that'll be in a separate
video but that's what's going on right now yeah
oh boy oh boy oh boy oh boy oh boy oh boy oh boy oh boy
[Applause]
look at that negative 22 degrees Fahrenheit that old Duramax starts every time I've never
had that truck not start in the cold with normal battery voltage pretty awesome but
with that said why I'm excited it's been
six months almost my engine is done for my GMC Sierra it's done I six two the machine
shop called they finally got all the parts not them not their fault they've been harassing
and calling and doing everything they can to get these parts but the manufacturers of
these Pistons have been way behind finally got them in they finally got the engine put
together it's now in a long block form and I'm gonna go pick it up bring it back and
then start the process reassembling my pickup
yeah I could have just used that oh what are those when it already happened in a video
and you guys are gonna see it or that's for a future video so uh sneak peek or old preview
same with those
I have no idea huh door's caught somewhere how do I get this thing out without break
it's an old door we've been trying to nurse it along as long as we can before we have
to put a new one in yeah I'll be getting close to that time
no
fire ass is catching got it all right
it's been a while he didn't remember me but we'll we'll get to know each other really
good real soon
