I bought 6 new Monark nozzles off Ebay for £72, then took them to Droitwich Diesel Services and paid £50 for them to fit the new nozzles to my injectors, including setting the pressures slightly higher, and giving them a thorough clean.
Mine's the old non-hydraulic tappets. Need to get round to adjusting them one day. Also got a leak on the turbo hoses somewhere - there's a high-pitched wine aswell as the normal turbo whistle...only been happening since I did the headgasket so I reckon it's just a connection somewhere leaking.
