hey guys uh real quick before we dive into this video um if you've been following the channel uh
normally on saturdays i tried to post a video of my personal project car behind me uh unfortunately
this week we were busy i wasn't able to get around to working on the car so i don't have anything to
post about it we'll catch back up with that next week in the meantime a little bit about this video
i had planned on just doing an engine teardown and basically an overall of the whole rebuild
process for this uh once we got into it it was in way worse shape than we had anticipated so i
decided to cut the video short i wasn't gonna use this footage uh just because of i don't want to
talk bad about anybody and i don't in the video i don't bring up any names i just point out a
bunch of issues that were done with the previous machine check and assembly process so i wasn't
going to use any of this footage i talked to the customer about it he was actually okay with me
posting the video so check it out there's a bunch of stuff in here to basically look for when you're
going through your you know this is a specifically a sleeved coyote but you know just some of the
stuff's just common sense stuff as well so uh check it out and uh let me know what you think
um
all right i want to do a time lapse video of a coyote this is going to be a tear down and
reassemble um it was put together by another shop i don't know really the whole story
uh at some point it was mistimed it broke a cam phaser i'll show you that in a second
um so it's only ran for maybe 45 minutes i believe so we're gonna tear the thing all down
uh check all the clearances check the tolerance just put it back together with some
different timing components from mmr uh so i'm gonna show you the broken cam phaser right now
check that guy out i feel like i mean it like came apart came apart
the chain's misaligned too it's just loaded this thing all oh it's all it's bad um
it does look like one of the cylinders made contact with the valves not surprisingly so
um we're gonna go through that probably have to replace a couple of valves but
hopefully the pistons survived and get through it so i'm gonna get rolling on
this time last video as i tear this thing down and hope you guys enjoy
foreign
all right i wanted to pause the time lapse for a second to show
you guys a couple things so look at this bank look at the pistons
look at this bank so it was definitely mistimed it was only running on four holes
a couple other things i noticed this is why you need to have somebody do these
that know what they're doing the sleeve that's impossible if you can hear it
there's my nail catching on the step between the sleeve and the deck now you can't have the deck
or the sleeve be below the deck specifically in a aluminum block situation because the box is
going to grow more than the sleeve so usually the sleeve is a though or two above the deck surface
and this is below it which means that at minimum the bot needs to get decked the other issues i
notice is this has block supports put in it if you're not familiar this is normally open right
you can see where they put this and then ported this to a lot of coolant back and forth but check
out the nick here see that mark from where they their bird got away from them and they put a mark
right in the deck that goes right from the coolant passage to an oil drain and you see them down here
that go externally same thing the burr slipped trying to get it to focus on that for you a
little bit better but the burr slipped and there's marks from it another one there now the other side
is the other three or the yeah three more fine but this one look at that going right into
i mean it took part of the sleeve away they went into it so far i mean it's almost i mean it's
close to being all the way in the cylinder i which what i would say would happen is they decked it
and then they decided to do that uh they should have done that by hand
and then decked it afterwards now obviously i don't know i don't even know who did the work
but uh i would assume that that's what happened there so i'm gonna keep tearing this thing apart
all right i had to pull this thing off the stain a second to uh pull the flywheel the
mid plate and the uh rear main seal holder up i wanted to show you guys look at how much silicone
these guys put on here look at that like there is no need to have that much silicone
on there like a thin film is all you need check that out it's even like into the
oil back of the oil drain deal look at that look at that loose piece there
kind of crazy that stuff could end up in your oil pickup tube you know here's the
cover show you again look at that look at how much silicone is inside the main surface just
overkill all you need is a thin film guys so i just wanted to
point that out before i got this thing back on the scene and we keep tearing it
apart
all right now that i got this thing all tore apart i wanted to go over a couple things uh the weights
and the crankshaft were put in vertically which isn't really the way to do it and then they were
mig welded and look at how those welds are pretty pretty rough uh you keep in mind this is an engine
that's going to turn you know 8 000 rpm the weight has to be added but if you watch our video on
engine balancing you'll see how the weights are supposed to be added in the crankshaft
the other thing all of the uh all the second rings were put in upside down one oil ring was rolled
on installation into the cylinder um look at these bearings these are a coated these are
normally a dark gray coated bearing uh all the rod bearings are her all the main bearings are
her the other thing you'll notice too is look at this oil squirter see that see how this one looks
that one's broken off three of these are broke which means they're coming in contact with the
piston so you add that up to the issues on the deck surface the sleeves being in the wrong spot
this thing's got a few issues and honestly none of those issues are why it came apart it came apart
because it was timed incorrectly on the intake cam on the uh driver's side bank and it crashed
the intake valves and it broke the phaser so you see here you guys saw me falling parts out of it
broke a rocker arm whatever um so it's a good thing we decided to go through this whole thing
got a bunch of stuff to fix get parts cleaned up and we'll start putting her back together
all right check out how small this hole is five and a half sorry
three quarters call let's go down a bit
oh so let's check that out just it's like five and a quarter halfway up almost five and a half
at the very top here five and a quarter again or five and a half sorry he'll move over to the next
that was that cellular move over the next cylinder look at this two and a half three
one at the top
very next hole again
two two two and a half and one okay
oh back up to five and a half again at least this one's kind of straight but yeah they're all over
the place all right so i didn't take any footage of us doing the machine work and reassembly again
after i realized how tore up this thing was i didn't think i was gonna use the footage
um but we ended up uh you see how off the bore sizes were they were like three foul different
a cylinder on that bank and on the other bank they were all pretty much the same size but
they had two thousands for the taper in them so we ended up having to excuse me honed the thing
to like an arbitrary bore size like eight thou and then i had the pistons coated that lined the line
to make up the tolerance difference um and put the thing back together we were able to deck the
block that cleaned up the deck surfaces uh we put a new crankshaft in it um rebalanced it obviously
and with the weights in it the correct way uh so it ended up being a bit of a project for the
guy we were hoping it was just gonna be a quick turnaround and turned into a bit of a nightmare
but we were able to get it knocked out and get it back together and out the door
so yeah just some stuff to look for on your engine and for who you're having to do the work you know
check their stuff out look for issues like this um but uh yeah that's all for this video hope
you guys enjoyed it i'll get some new content up uh next saturday of the our s197 behind me in the
turbo 400 swap so subscribe to keep an eye on that and the rest of our videos thanks for watching
