A new fitting to an Imps engine block

Its not that often that I can record a new fitting to suit the Hillman Imp engine block,well next year that engine will be all of fifty years old!

A day or so back I was fitting a new copper cylinder head gasket on the 998cc engine,when the first bolt I torqued down striped in the all alloy block,so whats new?

The best line of action was to call a specialist out who would do a repair,that was done on the same day and I was impressed (pun?)


A standard Rootes 3/8" hi tensile head bolt,marked Auto and really the best of the best quality,seen here its at least 45 years old. The thread insert is the wrong way around in this picture.



I contacted Nic the installation technical man and was given a fee for the call out and fitting fee,Nic was there the same day and did the thread insert.


The system is fast,not clean as much metal from the thread tap is ejected.


The new thread was more or less inserted by hand,then bonded with Loctite.

To be continued

How hard can this be!
