[TR] 57 TR3 head studs not lined up?

[Guy D. Huggins]

I'm relieved to hear that someone else is having this problem as well.

Randall was dead-on in that not all of these stud holes were tapped
perfectly vertical.  One of mine is off in two planes!

What I had to do was run the stud into the block by only a few threads
so that it still "wiggled".  I then slipped the gasket over the studs,
then slipped the head over the studs, and THEN full-on tightened
that one stud into the block.

Ass backwards, but it works.  This just underscores how the brits
have great engineers, but lousy machining.  At least the fellows
that tapped my holes didn't take the time to make sure the block was
level or the drill vertical.  Maybe it was nearing tea-time!


Cheers,

As Randall mentioned, I had to remove a couple of my studs to get the gasket
in place on the 4.

Mine are always tight, but usually I can work the gasket down without
damaging it too badly.  That copper is pretty tough, and a little damage
right next to the stud hole doesn't seem to hurt anything.

I think what happens is that the stud holes in the block are not perfectly
vertical, and not perfectly located; so there is some variation from engine
to engine and the problem may be worse at the top of the studs than at the
surface of the block.

You may have to remove the studs, lay the gasket in place and then install
the studs through the gasket.
