Amici,

In typically rookie race engine builder mode with the block I selected for
rebuild, I pulled the main bearing caps (with my new fancy DeWalt 20V
Impact Wrench) and then couldn't remember which way around they went.

This led to visions of catastrophic failure somewhere down the road. Yet, I
had several other blocks I could flip over and make a determination if need
be.

I was examining one of the caps when I discovered the faintest engraving on
the surface of each cap:

Eng #2 Front Fwd
Eng #2 Mid Fwd
Eng #2 Rr Fwd

Doug Brown, my original owner/builder/driver extraordinaire had engraved
each cap for me to make sure a mistake didn't occur. He rotated 3 engines
during each season in a quest for Divisional and National Championships.

I guess that is the way a aeronautical/mechanical engineer and very
successful racer thinks.

Thanks again Doug!

Cheers,

Especially if you want cam bearings in a TR6 block. Frustrating indeed.=20

 Many times a line-hone will get things back in spec, boring shouldn't move=
 the crank center more than a few thou, unless as the OP, non-matching caps=
 are being fitted, or the engine has been through some major trauma and may=
 have other issues.The cap is faced and the majority of material is removed=
 from it until the block has just a slight shadow left right at the parting=
 faces.
Yes the register for the seal housing in the block will then be oval, hand =
filing or, depending on equipment available, facing a little off one half o=
f the seal housing where it fits in the block will get it back on center.Ye=
ah excessive line-boring will add slack to the chain & change the deck heig=
ht, I've also seen engine mains & rods that were bored so much that there w=
asn't enough notch left for the bearing tang to fit, not recommended...

Yes, Bob, as far as I know you are correct, the bearing notches in the caps=
 and saddles are always on the same side.=C2=A0In 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 Hollist=
on, Mass. This creates two issues that must be addressed, both due to the s=
light raising of the crank center line:1) the clearance space of the top of=

<div>Yes, Bob, as far as I know you are correct, the bearing notches in the=
 caps and saddles are always on the same side.&nbsp;
<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 to =
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 mac=
hine in Holliston, Mass. This creates two issues that must be addressed, bo=
th 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 t=

<div>2) more of a problem is that the aluminum insert for the rear main sea=
