Anything and everything Herald. Talk about anything from the first 948s to the last 13/60s.

Engine, cooling system, fuel system, exhaust system.

I am about to take my 1200 herald engine apart in order to rebuild it - ie. replace bearings, piston rings and generally clean it up, hopefully without needing to go for rebore etc. (This is at least partly for the experience of rebuilding the whole car.)

I have read, I think in Callum's tutorial, that when the main bearing and big end bolts are tightened to correct torque that they stretch and therefore shouldn't be used again.

Along with all the other bits that I would be planning to replace, should I be aiming to replace these bolts as well or is this advice for those building high performance engines. (The engine is an unmodified 1200 with a single carb and it is intended for gentle road use only.)

Many thanks for any help which can be offered and for the invaluable advice which I have previously received.

Steve.
