Unhappy Have a tapping noise.

1989 560 SEL. Finished putting a new cam shaft in around two weeks ago. Have been driving the car everyday since. Today, when I got home from work, I hear a nasty tapping noise. The noise sounds like the rockers. I checked the oil and it is clean and at a very good level. (it was about a half a quart low so I topped it off.)

Can anyone possibly shed some light on my situation?

Respects,

Andy

rockers

Andy,
I take it you replaced the rockers as well not just the camshaft. If not I would recommend you do.

Yes, I replaced the rockers and the tower bearings. I also put new oiler ends on a very clean oil pipe. Used lots of MB assembly lube too.

Can it be that the rockers and cam have been broken in and that I need to shim the lifters more?

Respects,

Andy

broken in

I am not sure it should break in. The system is self adjusting so they should always be adjusted correctly. Have you pulled the valve cover and had a look to make sure everything looks okay and the cam is getting oiled. It is messy but well worth it to check.

I assume you got the right came for your specific engine, MB cams vary based on the engine designation. I am sure you did but just checking.

Thanks for the reply. Yes, it is the correct cam. What is very puzzling about this is that i have put a couple of hundred miles on the car without a problem. I did just put a new cap and rotor in, but all that did was make the car easier to start.

Thanks all.

please help

It would take a couple of hundred miles to do any damage to the cam. Have you pulled the valve cover to inspect it.
