Started another job that needed doing.

Have stripped the engine down and got to the head & manifold bolts to
remove...

Simple question, whats the size?

1.3mm or 1.4mm could be one of those things where some are diff size so
if i was you i would have 3 sizes ready 1.3 1,4 1.5mm

I meant for the head & manifold bolts. The head bolts appear to be a
Torx type and the manifold is a Hex bolt, I need to know the sizes.

Assuming that it is the same engine as the 1.9 DT 406 then that nice Mr
Haynes only gives a size for the head bolts but I have included his comments
on the manifolds:

Cylinder Head: T55

Inlet Manifold: Quote - "Using a suitable hexagon bit or allen key remove
the bolts securing the inlet manifold. Loosen, but do not remove, the
central hexagon manifold securing bolt - the manifold is slotted".

Exhaust manifold: Qoute - "unscrew the six manifold securing nuts and
recover the spacers from the studs".

Don't know if that helps?

Whooops, must of missed that bit in the manual... Guess I will have
to speak to the dealer about the manifold bolts to see if they can
give me the sizes. Thanks for the reply.

In fact, come to think of it, I could probably remove the head with
the inlet manifold still attached and just remove the exhaust
manifold. This way I wouldn't have to bother with the hex bolts on
the inlet side.

It is easier from what I remember to take the inlet off, which has
13mm nuts or bolts, and then remove the exhaust from the head. It's
also easier to get at the turbo feed pipe on top of the turbo.
On some engines a couple of the fixings for the inlet are allen key,
6mm I believe.
