Hi, I spent a nerve wracking weekend removing my engine and dismantling it suspecting a dropped valve and wreckage that actually turned out to be nothing other than the accelerator pump tube I lost months ago finally finding its way into 3 (why 3!?! as if it hasn't got enough to deal with !) I bought new Ps and Cs expecting the worst and I've decided to fit them anyway- I figured that I don't know much about the cars history and it would give me peace of mind. Are there any recommendations for running in a new set? I think I read somewhere that you should run the engine hard for a few minutes to ensure the rings bed themselves properly. Is that a good method? I was just going to oil them well on assembly but do they need something special? Is there a recommended procedure from the gurus? Also I'm going to replace some valves. The guides seem OK but again for peace of mind I'd like to replace the exhausts. They all look absolutely fine- no stem wear, good makes (VW stamped) and clean shiny seats. For cost reasons if I do replace them it will probably be with Osvat valves rather than genuine VW valves which seem ridiculously expensive. I know that Jim already warned me against using valves that didn't have a chromed stem. These don't seem magnetic at all anywhere so I guess they can't be plated. I found this link though: http://www.unitn.it/internazionale/area_ric/progetti/nano_vhof.htm that suggests that Osvat are pioneering in new technologies so can they be that bad? Do I need to replace the intakes as well? I'm getting paranoid now about dropping one but has anyone ever had an intake break?
