Nocking at start up on 190E - how do I stop it

[white190]

I have a 1993 2.0 Auto 190E , for the first 5 to 10 seconds or so each day the engine knocks till the oil pressure rises . Is this normal ? , Or is there a way to stop it . I have already replaced ALL the hydriolic tappets and spray bar. The duplex chain seems in good condition. The engine runs very quite now after the first few seconds . It just worrys me that dammage may be happening in the first few seconds after cold start.

Any one got any suggestions.

Ps I not scared of the spanner , so if mechanical detail is given it will be appreciated.....

Hi

I would try rocker arms. That usually cures the problem. If the tappet noise is being persistant.

Thanks I'll try that
Is there any way of telling which ones are worn or is it a case of renewing all 8 ?
