560sl Febi hydraulic lifters

I have bough new Febi set of hydraulic lifters for my car since the old ones were making clicking noise on idle. Now with new ones installed I have a short 5-10 second clicking during cold start up. My mechanic have changed 2 new ones and installed 2 old ones, but I still have the clicking sound at start up. Mechanic says that there might be maximum 1 more lifter that should be changed saying that Febi does not make quality lifters and he had such a case for couple of times. Everything else is OK (camshaft, rocker arms..). Also I have recently changed chain, tensioner, guides.

Any experiences like this or possible solution.

Thanks in advance.

How are the cam followers and lobes? Worn any (and I mean, any, it doesn't take much to cause a clicking)?

Does the mechanic understand how to measure and select shims?

Cam folowers/lobes are in great condition per mechanics opinion.

I have also thought about shims in order to level the lifters, but I was told it should not be done at this moment...I was told that shims are used after head job...

Mechanic said that it is obvious that 1 or more lifters loose oil during the night and you could here them at cold start up. This is not the 1 case with Febi lifters in his work...He is very experienced Mechanic he owes authorized Mercedes service for more than 30 years....

My car has 125K miles.

correct Base shim adjustment is critical at anytime, may have been your issue to begin with, most shops i have seen don't like to do it or do not have the correct tool (see pic below) and shim assortment, it can also be quite time consuming if they are not familiar with how to do it. also the wrong shims can not only cause noise, but misfires and rough idle. sounds like you need to find a better mercedes shop. ask if he owns this tool and shim set.

I agree. But what if some new lifters do loose oil overnight....which I believe is the case..Then the lifter is the coolpit. The clicking sound goes away in just few seconds after start up.

Perfect is the enemy of good

If you are down to one clicker and only at start-up, you may want to consider living with it. If the valves are quiet the rest of the time, the shims are OK. It is tough to locate a single clicker at cold start-up.

Thats what seems to be the only problem...hopefully it would be solved. It is just annoying knowing that all lifters are new and some of them cause trouble.


Thanks,
