2.1 zvh engine

top end tapping when cold
5 mins into driving and it’s fine
any suggestions as to what I can do to sort it
thanks

 

Hydraulic or solid lifters? Checked gaps if solid? Checked cam conditio/hydaulic condition?

 

Not checked anything yet just hopefull that some 1 might have been able to recommend something to check for
I don’t want to take it apart just yet as want to use it mid week and don’t get much time to work on it
next weekend it will be taken apart as rocker cover going to powder coaters so ideal time to look and see
