I have a slightly tappetty no1 cylinder - i put oil flush through the engine when I changed the oil a while back hoping it would go away - it didn't.

It's not bad and I'm in no hurry to change them but I'm lining up jobs to do on wet weekends. If anyone has got any known good ones lying about - don't need a full set as I'm fairly sure its only the one cylinder.

Ta,
Chris
