Noooooo.
I don't want to read posts like this.

My engine was overhauled by my dad and I a couple of years ago and it now has +- 50 000km on this.
Now the big worry after reading this.
We replaced ONLY the head bolts and used the same conrod bolts when we assembled everything.(This is in the bolts department).
I have heard that bolts stretch and must not be reused.(Only heard this a couple of years after the engine was back in the car and running)
That is why head bolts must not be reused.
But, my engine sees once a month AT normal operating temperature 6000rpm.
It is stock bottom end and was not balanced.
Must I expect a conrod flying out of the bonnet because we reused the conrod bolts or is it not a problem.

Sorry if I hijacked your thread dattoman.
