				start up rattle
			 
			 
			
		
		
		
			My 2000 boxster s has the cold start up rattle that many have reported. It only does it the first start of the day. I think it is a  chain tensioner (all three are new) bleeding down or lifters bleeding down. Can an oil pressure release valve cause this noise? The noise is loud and i would really like to fix it. Verio cam tensioners and pads are also new.
