I have owned a flock of Volvos, including my beloved P1800s.
The one car I wish I’d never sold.

A 164 I bought with 100k +, used a bit of oil.
So I go for rings, rods, mains...

I pull the head and number each piston, works best if they return to the same hole.

After cleaning the pistons, I notice TWO NUMBERS on each piston???? And not the same order!!!!
Did I mark them twice???

Turns out the pistons are hand fitted to each cylinder.
So a piston that was to the outside of the spec went a bore that was also to the outside...

Also SEVEN MAIN BEARINGS!!! On a 6.
Last a very long time.

I will say nothing about Lucas.
