change the lifters ti ina`s,tappets are funny at times my car and my mates both tapped like hell when first built,mine are now fine 2k on,his are still there but not as bad

if it comes and goes it will defo be tappets,bottom end noise is alot deeper noise


i remember having to do a set on a 4x4 saph i had and it cured it instantly

tappets have a mind of their own
