Habit from a long long time ago error made me mark each main cap in my
engines with a  center punch and the side of the block area with a simular
mark so that reassembly would always be  correct & easy.  This came from my
work in the very early 50's and unknown engines for all over the world
where you'd better have a clue on how to put that devil back together.

Yes, Bob, as far as I know you are correct, the bearing notches in the caps a=
nd saddles are always on the same side.=20
In the TR wet sleeve engine, each cap is unique as to its position, so it sh=
ould be really hard to mix them up.
Kas is right, however, in that in many engines it is good practice to mark e=
ach cap as to position and orientation, just to be sure.
I have had a wet sleeve block line bored just to true it up at ABT machine i=
n Holliston, Mass. This creates two issues that must be addressed, both due t=
o the slight raising of the crank center line:
1) the clearance space of the top of the pistons needs to be checked to be s=
ure there is no interference at TDC. Usually not a problem.
2) more of a problem is that the aluminum insert for the rear main seal may i=
nterfere with the block. This will become apparent when using the centering t=
ool, and can be addressed by filing down the area of the seal where it inter=
feres. Do not file or alter any other surface, as this will compromise the a=
bility of the seal to function and/or to hold correctly one of the aftermark=
et rubber seals.  Be careful also not to gouge the face of the aluminum seal=
 where it mates with the flat surface of the block. Go slow and be careful. I=
t should all work as intended.

What about the chain? Is there noticeably more slach of it?=20
The chain tensioners do almost nothing . Sometimes there are deep grooves i=
n a short time, sometimes there is almost no scoring. Probably this is beca=
use of the chain running smoothly or with severe oscillations. Oscillations=
 of the chain will have an influence on the ignition timing too.=20
Has anyone tried an alternative solution for the tensioner to keep the chai=
n quiet?=20

Yes, Bob, as far as I know you are correct, the bearing notches in the caps=
 and saddles are always on the same side.=20
In the TR wet sleeve engine, each cap is unique as to its position, so it s=
hould be really hard to mix them up.=20
Kas is right, however, in that in many engines it is good practice to mark =
each cap as to position and orientation, just to be sure.=20
I have had a wet sleeve block line bored just to true it up at ABT machine =
in Holliston, Mass. This creates two issues that must be addressed, both du=
e to the slight raising of the crank center line:=20
1) the clearance space of the top of the pistons needs to be checked to be =

firstly, are you 100% sure the caps are correctly fitted both round the rig=

you need to decide if the caps are misaligned across the block or if the tu=

if the alternative caps have a significant step to 1 side, so you will clea=

if the stap is very minor, like a few thousandths of an inch, then the face=

if it is really bad, like many tens of thou, then you have to firstly move =

<div>Speaking of main caps I bought a block that turned out to not have the=
 original main caps. The caps on there did not match up with the block but =
I=E2=80=99ve been unable to find a machine shop that can machine them so th=
ere=E2=80=99s a round hole for the crank. The shop I had do my last block (=
and they do 427 race engines among others and are well respected) told me t=
hat the result would be ovaled out holes (not round) which obviously is not=
 good.
<div>Certainly there=E2=80=99s a way to make this work but I haven=E2=80=99=
t found it. I checked out another block shop but said they subcontract line=
-boring to the the shop that said they couldn=E2=80=99t do it.&nbsp;</div>

<div><br clear=3D"none"></div>

<div>Has anyone else encountered this problem? I=E2=80=99ve heard that stee=
l mains might be an answer but they=E2=80=99d still have to be line-bored t=
o make them match. I hate to ship a block to get this done before I have re=
assurances that they can make it work but does anyone know of that has succ=
essfully made main caps match the block? Given I=E2=80=99m spending a lot o=
f time these days staying home and catching up on car projects in the shop =
I figured it would be a good time to start building the next engine.</div>

<div>In typically rookie race engine builder mode with the block I selected=

Hi Marcel;
Line boring should not materially affect the chain itself, as the crank cen=
terline is raised usually less than .005". =C2=A0Might affect cam timing a =
bit, but in the worst case scenario that can be fixed with a Vernier sprock=
et.
However, I agree with your assessment of the tensioner. =C2=A0Would like to=
 know if there is a better solution.

I did have a sound block that came without bearing caps and a supply of
"almost fit" caps. Not wanting to waste a good block I spent the money to
have it line bored.  I've got a pretty talented machinist here in Austin
and he trimmed down the caps before sending it out to get lined bored.
Worked fine.  Unfortunately the outsourced machine shop that he used for
the line bore shut down a few years back.

Bob,

Do you know whether the outsourcing shop was the one in Elgin, TX=3F =C2=A0=
Keith Kubosh, the guy who bought that place, has all the old equipment th=
at Mike used, but I don=E2=80=99t know whether or not he=E2=80=99s learne=
d to use the line-boring machine yet. =C2=A0His welding job takes up most=
 of his time but when I was last there a couple of years ago he was doing=
 some engine work.

<div dir=3D=22auto=22>Yes, Bob, as far as I know you are correct, the bea=
ring notches in the caps and saddles are always on the same side.&=23160;=

<div>In the TR wet sleeve engine, each cap is unique as to its position, =
so it should be really hard to mix them up.</div>
<div>Kas is right, however, in that in many engines it is good practice t=
o mark each cap as to position and orientation, just to be sure.</div>
<div>I have had a wet sleeve block line bored just to true it up at ABT m=
achine in Holliston, Mass. This creates two issues that must be addressed=
, both due to the slight raising of the crank center line:</div>
<div>1) the clearance space of the top of the pistons needs to be checked=
 to be sure there is no interference at TDC. Usually not a problem.</div>=

<div>2) more of a problem is that the aluminum insert for the rear main s=
eal may interfere with the block. This will become apparent when using th=
e centering tool, and can be addressed by filing down the area of the sea=
l where it interferes. Do not file or alter any other surface, as this wi=
ll compromise the ability of the seal to function and/or to hold correctl=
y one of the aftermarket rubber seals.&=23160; Be careful also not to gou=
ge the face of the aluminum seal where it mates with the flat surface of =
the block. Go slow and be careful. It should all work as intended.</div>

<div dir=3D=22ltr=22>firstly, are you 100% sure the caps are correctly fi=
tted both round the right way and in number order=3F
<div><br /></div>
<div>you need to decide if the caps are misaligned across the block or if=
 the tunnel is simply oval because&=23160;the hole in in cap is too far u=
p or down. this will need a combination of feel and measurement<br />
<div><br /></div>
<div>
<div>if the alternative&=23160;caps have a significant step to 1 side, so=
 you will clearly feel a ledge at the mating faces when they are tightene=
d up<br /></div>
<div>
<div><br /></div>
<div>if the stap is very minor, like a few thousandths&=23160;of an inch,=
 then the faces of the cap are machined down to create an oval hole, then=
 it it is align honed</div>
<div><br /></div>
<div>if it is really bad, like many tens of thou, then you have to firstl=
y move the cap sideways by machining the register on 1 side and peening&=23=
160;it on the other, and effectively moving it sideways, followed by bori=
ng/honing</div>
<div><br /></div>
<div>sometimes, the bolts are too neat a fit to allow this and if thats t=
he case, its usually easier to find some other caps or make them</div>
<div><br /></div>
<div>if the tunnel is simply&=23160;an&=23160;oval because the cap is too=
 far up or down, this is usually easily fixed by facing the cap mating su=
rfaces and reboring the tunnels</div>
<div><br /></div>
<div>not all engine machine shop have a line borer...mine did not, so sub=
contracting the job is not uncommon</div>
<div><br /></div>
<div>the end result should be a perfectly round hole with a super fine ho=
ne (cross-hatch) mark on the bearing faces, to ensure&=23160;perfect bear=

Hi Phil =E2=80=93 There is a better solution to the stock tensioner. It =

Hi Marcel;=20

=20

Line boring should not materially affect the chain itself, as the crank =
centerline is raised usually less than .005".  Might affect cam timing a =
bit, but in the worst case scenario that can be fixed with a Vernier =
sprocket.=20

=20

However, I agree with your assessment of the tensioner.  Would like to =
know if there is a better solution.

What about the chain? Is there noticeably more slach of it?

The chain tensioners do almost nothing . Sometimes there are deep =
grooves in a short time, sometimes there is almost no scoring. Probably =
this is because of the chain running smoothly or with severe =
oscillations. Oscillations of the chain will have an influence on the =
ignition timing too.

Has anyone tried an alternative solution for the tensioner to keep the =
chain quiet?

Yes, Bob, as far as I know you are correct, the bearing notches in the =
caps and saddles are always on the same side. =20

In the TR wet sleeve engine, each cap is unique as to its position, so =
it should be really hard to mix them up.

Kas is right, however, in that in many engines it is good practice to =
mark each cap as to position and orientation, just to be sure.

I have had a wet sleeve block line bored just to true it up at ABT =
machine in Holliston, Mass. This creates two issues that must be =
addressed, both due to the slight raising of the crank center line:

1) the clearance space of the top of the pistons needs to be checked to =
be sure there is no interference at TDC. Usually not a problem.

2) more of a problem is that the aluminum insert for the rear main seal =
may interfere with the block. This will become apparent when using the =
centering tool, and can be addressed by filing down the area of the seal =
where it interferes. Do not file or alter any other surface, as this =
will compromise the ability of the seal to function and/or to hold =
correctly one of the aftermarket rubber seals.  Be careful also not to =
gouge the face of the aluminum seal where it mates with the flat surface =
of the block. Go slow and be careful. It should all work as intended.

firstly, are you 100% sure the caps are correctly fitted both round the =

you need to decide if the caps are misaligned across the block or if the =
tunnel is simply oval because the hole in in cap is too far up or down. =
this will need a combination of feel and measurement

if the alternative caps have a significant step to 1 side, so you will =
clearly feel a ledge at the mating faces when they are tightened up

=20

if the stap is very minor, like a few thousandths of an inch, then the =
faces of the cap are machined down to create an oval hole, then it it is =
align honed

=20

if it is really bad, like many tens of thou, then you have to firstly =
move the cap sideways by machining the register on 1 side and peening it =
on the other, and effectively moving it sideways, followed by =
boring/honing

=20

sometimes, the bolts are too neat a fit to allow this and if thats the =
case, its usually easier to find some other caps or make them

=20

if the tunnel is simply an oval because the cap is too far up or down, =
this is usually easily fixed by facing the cap mating surfaces and =
reboring the tunnels

=20

not all engine machine shop have a line borer...mine did not, so =
subcontracting the job is not uncommon

=20

the end result should be a perfectly round hole with a super fine hone =
(cross-hatch) mark on the bearing faces, to ensure perfect bearing shell =

Amici,

In typically rookie race engine builder mode with the block I selected =

I was examining one of the caps when I discovered the faintest engraving =

Doug Brown, my original owner/builder/driver extraordinaire had engraved =
