Thanks for the reply Steve, I did realise that.
The reason I ask the first two questions is to see if anyone knows when Vauxhall Motors Ltd released 'Field Remedy 1532'. This information could be very useful.
The other point is that Vauxhall Motors Ltd, are admitting that a component that they have designed and manufactured is "not fit for its purpose" (refering to the oil distribution nozzle) as stated in the TIS
'Cause: Missing or insuffient lubrication of the timing chain'
and as we know has now been replaced by a modified part.
We have evidence (from some of the members and photographs from this website) that not just the vehicles with engine numbers before 11065400 are fitted with the older oil distribution nozzle.
My brother-in-law is a partner for a firm of solicitors and is a litigator who deals with "specialist disputes". I am drafting a letter (with his help) to Vauxhall Motors Ltd, regarding the whole issue, having spoken to a Technical Services Manager who did in fact issue me with a personal case number, representing all Vauxhall owners, especially those who have contributed to and aided other members on this web site.
It will probably not get anywhere but I will at least give it a go.
