2wd cosworth
205 block
4x4 pistons

strats from cold & is perfectly quiet
2-3min running a little noise appears
noise is constantly there from this point

once revs is brought up to 2/2.5k its gone & is perfect all the way threw the revs

cain the death outa it & stop & noise is gone, 2 in idleing & its back?????

sounds like slight piston slap noise but surely this should go once warm???
listened around teh bay & if anything seem to be comeing from rear of engine but dont take my word for it. lol

little end bush???????
oil presure issue???

dont think its shells as its perfect from cold & doesnt get anywose when revved/driven

few people have told me not 2 worry as isnt that bad but its annoys the sh#t outa me!
