The main is eaten by electolysis with a bit of rust on the journal. Pity as they could possibly have gone back in as the others look OK.
Bores are still STD too. See what they look like after a bit of a cleanup.

I agree that the 'main' surface is too far gone.
Those pistons, are they the old fully ventilated type not normally found in modern motors?
.

I measured the pistons i have & they are for a 1595 engine , I am sure I have some @L pistons to John Bradshaw & I dont think he used them . I think they were std & he wanted oversize . Thats bad luck about the shaft My P3 sat from 1974 to about 2000 with a sump full of water with out any problems ( car went under in 74 floods), just lucky I guess . Wayne

The water level was so high it was pushing oil out the diptick tube.
Ran the hone through the bores, a couple are not too bad but looks as if it needs a rebore.
The left piston is a 20 thou OS from a 2.6. Apart from the gudgeon it looks as if it is pretty close. Perhaps the hole could be sleeved down and with a bit of gentle use of the angle grinder to change the profile and balance they might work.
Not sure on the availability of new 2 litre pistons.

The one to talk to is Ian Cox from Cox & Turner Egineering in the UK

Have you got any 3 litre pistons? the 3 litre bore is the same as the 2.6.

Hasn't the 3 Litre got the same stroke as the 2 Litre?
The conrod's could be the same.

If the bore is the same, whats the difference?
No 3 litre pistons here only 2.6 from a few old donks resting here.

Not sure about difference but thought they may be closer to the 2 litre than the 2.6 ones.

Someone to try may be Master Chief or his dad Hilton Pollard, he even had a set of .060 pistons for 1595 engine so may still have 2 litre stuff.

The only 3 litre stuff I have is 2 complete engines, one just reconditioned and the other good running second hand.

Havnt seen a 3 litre but the 2.6 rods are slightly longer than the 2 litre and the big end journals have less width than the 2 litre.
