Con rod nuts & bolts.

Just getting back to rebuilding my ZPJ4 after a long illness...i,m trying to find a set of 12 con-rod nuts & bolts...local dealer are useless.

I assume you have the part numbers and have performed a search and drawn a blank.

The best source of Prv parts is probably via Delorean suppliers.

As you are just after studs, nuts and washers, have you tried a local engine parts supplier/rebuilder, or even a reputable fixings and fastenings outlet?

The 3 ltr.con rod nuts & bolts are different from the 2.8 in the Delorean & are no longer available...so anyone rebuilding their engine the con rod nuts should be renewed same as the cylinder head bolts.

Have you tried the Renault part number, they did use the 3.0 litre engine in the 25 and Espace and possibly the Laguna.
They are shown as 11mm as opposed to the Psa ones being 9mm, which seems odd for the same engine.
An even more long shot would be the Talbot Tagora.
The Eagle Premier and Dodge Monaco used the 3.0 PRV6 so there is likely to be supply as they are in plentiful supply.

After a bit of research...there is only 1 con rod bolt for ALL engines 9mm x 1mm...the oem nuts with 11mm flats with a shoulder are stretch nuts & should be replaced on rebuild...these are the one,s no longer available...the early 2.8 etc. nuts with 13mm flats are normal high tensile 200,000lb nuts & are available...so 12 new nuts on there way from Delorean Europe...forgot about the yanky cars.

Thanks for the new info.
If you really want the original 11mm nuts search for the Renault ones, possibly the PSA nuts also.
I found a supplier and iirc, they had stock. Iirc, it is European car parts in Stafford.

TBH, I think you are going down the correct route.
To check the bolts haven't suffered any stretch just wind a new nut down the length of the thread.
