Re: Engine noises
sounds like a noisey tappet, possibly because it is starved of oil. check your oil level. if its ok, add a can of engine flush to the engine oil and let it idle till it gets hot, if it gets noticably quieter you know oil starvation is the problem and you need to flush the oilways. dont forget, dont drive around with the engine flush still in.
other possibilties are a dead tappet, or a worn camshaft lobe causing the valve clearance to be significantly out (compression test could confirm this).
