Well I beleive Iv'e done it.
Taken a lot of time and bloody mindedness.
Nipparts Complete Timing Chain Kit for above engines.
From Unipart Part Number N1156000. £123.33p + vat.
So just short of £150 for the Kit.
Apparently this is the OEM Part.
Hence the reluctance to sell it to Private Buyers.
Something to do with model age so they couldn't sell privately - BUT THEY CAN NOW. !! Ye Haaaa.
Decent Price as well I think.
Fill your boots. LOL.
Still Special Order and takes about two weeks.
