Sorry I still don't know the difference between valve lifters and tappets. I read this in another post on a similar subject.
You have one or more bad tappets in teh 190D -- like hydraulic lifters except directly between the cam and valve. Known problem with these cars, you have to take the cam out to replace them.
Do you think my problem is the lifters or the tappets?
Help me as soon as you can please as I want to have a go at this today if possible.....Thanks
