- Hey, this is Davin
with Hagerty and our
redline rebuild series.
Working on the Buick engine today.
Last time you remember, we were stuck.
We were stuck on the head
and all based on our exhaust valve choice.
So, we're in process of resolving that,
but at the same token,
I have got to get this,
short block assembled
and put it all together.
So, today's task is to,
get the cam bearings in,
get the cam plug in,
get the crankshaft in
and start assembling it
from the bottom end.
And in the meantime,
we're gonna test fit
a little different design.
Actually, give me the other one.
This one.
We're gonna test fit a little
different design of piston.
I'm not real happy with what I got
and I got a little
different idea this time.
So we're gonna try that
this is a printed piston
that one of our very own
did for us in his basement.
Fantastic to have friends.
And structurally,
obviously it's not gonna last,
but dimensionally it'll give me the,
the nice surface up here
so I can check my clearance
cause it'll fit nice in,
nicely on the piston rod assembly.
And then of course go into the bore.
(upbeat music)
(metal clanging)
(metal banging)
(metal banging)
(mumbles)
- It's gonna be the same.
All right, yeah.
We have a very slight snag here.
This oil plug for the main feed rail.
This plug has to be flushed
to the back of the block.
Otherwise the big adapter
plate that comes on here
obviously will not sit flush.
It'll sit cockeyed similar to like your,
your cam plug back here
also has to be flushed
to the back surface.
So what I'm gonna have to do,
unfortunately at this point,
everything is clean
and ready to assemble.
I'm gonna have to take a tap down
into this hole.
This is a pipe tap,
which I did clean it up prior,
but I didn't double check and make sure
that plug would sit flush.
So I'm gonna have to come in here
and run the tap through it.
Now obviously as I go through and do this,
I'm gonna pick up paint
and I'm gonna pick up steel.
Now what I can,
what I'll be able to do
because there's a port right here.
I can take, I can blow
some air down through this
and get most of it to come out.
But then what I'll do,
or what I found works quite well,
is take a magnet,
'course put it into the hole
and you'll pick up all those,
shavings and such that are
left behind by the tap.
So that's the process.
Obviously it is not the best thing
but you also can't have the
adapter plates sitting sideways.
I'm almost flushing down.
Well, close to tight.
(tap screeching)
I went too far.
(tap screeching)
How's that look?
Nice, huh?
Nice.
(metal banging)
Nice, nice, nice, nice.
- I don't think there's anything
that I've ever seen Woody Harrelson in,
that I don't like?
- When he promises though.
- Is that power coat in the ...
- It's E-coat but it still
has some amount of build.
(metal banging)
Shave it out of those holes.
We ran into a very small snag.
So I had these adapter
plates for the transmission.
I had them E-coated
and this, the stud on the other plate
didn't get a mast off which is fine
based on the process you really can't
and then of course the meeting hall,
no big deal.
I'm just gonna take a
sanding roll on dire grander,
cleaning it out real quick.
Not trying to remove any material,
just the amount of E-coat it's,
It's only probably a thousands
but it's a tight fit.
So, we'll pull that off
and be back in business.
(upbeat music)
(metal screeching)
(metal banging)
(lips smirking)
Yes.
All right, it's up on
the big engine stand.
Next step, I'm gonna
throw the camshaft in,
put the main bearings in, crank shaft
and get the timing chain
and everything on the front.
Moving forward.
(upbeat music)
It's in there.
I'll have to get it out.
- Yeah.
- Okay, during the blueprinting process
here of the engine,
you always wanna go through and measure
your journals on your crank shaft
and then relative to the bearings
when you put them into the block.
So for instance right now,
what I'm working on specifically,
is knowing exactly what
the crankshaft measures,
as far as each of the five main bearings
and then I'm gonna take the bearing caps,
torque them to spec into the block
and then measure that OD.
The difference will give
me the oil clearance.
Now, there certainly are
other ways to do that,
you can use some stuff
called plastic gauge
and I prefer a set of micrometers
Well, because these are actual gauges
Opposed to the other.
So while the crankshaft's out,
I'm gonna, I'll take
advantage of measuring
both the ride and the mains
at the same time and have
my crankshaft numbers.
All right, so you'll notice
that I've made a little upgrade
from my last engine build
where I'd normally just throw this out
on a piece of scratch paper.
Now I actually have a printed out
version of a building sheet
and I'm going to vet out
what's actually needed from there.
And obviously I'm not making
any changes to these journals,
By the way I'm verifying that
what I asked for, relative to size
is what they ground it to.
Or there was no miscommunications
in what I was asking for
so far, everything looks,
looks pretty good.
(metal banging)
So, main torque spec is
90 to 100 foot pounds.
I'm gonna push it towards
the hundred foot pounds.
Then I can measure the ID.
Otherwise the bearing is not compressed.
(upbeat music)
(sighs)
(metal banging)
(metal screeching)
All right so, you'll notice I do not have
that backing plate on here yet.
'Cause I am purely mocking things up
and I did torque everything down
and so on and so forth.
But now I can take and put the
rod on to this plastic piston
set it down into the hole
and it will rotate through its stroke.
And I'll set the head on obviously as well
and check the valve clearance.
And we also have the correct valves.
So we can rectify the issue
that we had with these valves,
with this little edge on here,
we now have some other ones
and what it amounts to is,
they made them both ways.
So we got the luck of the draw
in the first batch.
Where it had this little edge on there,
wouldn't work for us
and now we got it nice and smooth.
And I will not have to
shave down my guide.
Another three, 400 thousands.
I can maximize how much
length of that guide I have,
which is what I was after
So next time we will finish
their mock up with that piston
and get that design kicked off.
And then we'll also finish up
the assembly on this heads.
Of course, that's all God willing
and we don't have an issue here again,
but hey, we're making progress
and that's just the way
the ball bounces sometimes.
Sometimes you can see the windshield
and sometimes you just see the
bugs smacking the windshield.
So, hey, get out in the
shop, get your work done.
I'm done for the day
but I got plenty of stuff to do otherwise
but get out and enjoy the day.
See ya.
(upbeat music)
