From the life of a journeyman mechanic - you can also be too quick when repairing things
Nowadays, most customers - exceptions prove the rule - believe that they can't spare their vehicle for an hour. The garages know a thing or two about this, but they have adapted to it, indeed they put their ambition into getting their customers' cars back in order as quickly as possible. Now, in general, this fixity is highly commendable and gratefully welcomed. But it is not always appropriate.
This was an obvious case: the engine of the car that came in - it seemed to have become very hot - was suffering from a blown cylinder head gasket. And because a work group had just become available, they immediately set about removing the cylinder head. The surfaces were cleaned, the spare parts store supplied a new gasket, and in no time at all the cylinder head was back on, the cylinder head bolts were tightened in the prescribed sequence and to the correct torque, and before the engine block had really cooled down, the car could be handed over as finished - after the cooling water had also been topped up.
"That went well" thought the customer and drove off satisfied.
Not long after, however, he returned to the workshop with a less than friendly face, as something seemed to be wrong with the engine. The cylinder head was removed again, but this time the master instructed him to wait until the engine had cooled down.
Now the tensions in the head and block could equalize, which was not possible during the first "quick assembly". The head had warped so much that even the new cylinder head gasket could no longer seal properly. Speed is good, even very good, but not in every case.
You must not forget to think, because things do not always turn out as well as in this case. Once the cylinder bores have warped, the situation is much more unpleasant.
