MGBGTV8
- cylinder head removal & replacement
How did the Buick V8 engine find its way across the Atlantic
to power a generation of Rover and Leyland vehicles?
This article by Chris Goffey in Autocar in November 1976 was
reproduced in the V8 Register Journal New Year 1980 by kind
permission of Autocar issued to the V8 Register in 1979. It's
a fascinating story of William Martin-Hurst stumbling across
an aluminium Buick V8 engine lying on the floor of an experimental
shop at Mercury Marine and then negotiating for Rover to make
the engine in the UK. More

V8 cylinder head
For most of us the first step in any significant engine work
is to consult the Workshop Manual and check the manufacturer's
procedures and technical data. Knowing the origins of their
V8 engine it will not surprise MGBGTV8 owners that there are
two official manuals for their engine but what will surprise
them is the conflicting data they present. The documents in
question are the MGBGTV8 Workshop Manual Supplement (AKD 8468)
released in 1973 by the Service and KD Division at Cowley ("MG
V8 Supplement") and the Rover Overhaul Manual (Publication
Part No. LRL 0164ENG 2nd Edition) published by Land Rover in
2003 ("Rover Manual").
The MG V8 Supplement former publication was written in 1973
when the Rover V8 was still a relatively immature product with
another 20 years of development and production ahead of it.
It is one of the benefits of owning this long-lived engine that
much of the service experience is incorporated in an updated
official manual. The purpose of this article by Jim Livingstone
is to identify the significant updates as they affect the operations
involved in removing and replacing the engine cylinder heads.

Jim says there are several specific areas where the instructions
in the MG V8 Supplement are questionable and alternatives should
be considered when removing and replacing a V8 cylinder head.
The areas are: Cylinder Head Bolt Tightening Sequence, Head
Bolt Lubrication and Tightening, Head Bolt Anti-Seizure Measures,
Inlet Manifold and Gasket, Exhaust Manifold Assembly. Cylinder
Head Gasket Assembly and then the detailed removal and replacement
procedure.
