There are plenty of chinese made aftermarket gaskets for M275. Anyone used or tested these? Are there any particular brands that are better than others? Just curious.

It takes how long to do cam cover gaskets in a 275? Is it worth saving $$ for that?

Intake gaskets? Exhaust manifold to head gaskets? O-rings to seal all the spots they are used?

When any of them fails after a year or two did you save any money?

As always; your car your choice.

I was just interested to know whether somebody have used them or not.

Get Victor Reinz, they are OEM

Yes, I know, but that was not the question.
Are you sure that Victor Reinz are not made in China?

I don't know, but Victor Reinz works.
I've personally have replaced my gaskets with those and they never caused any issues,

Goes for the intake and valve cover gaskets

Not sure if this applies to m275's, but people with m113k engines on the forum (and site reviews) INSISTED that Victor reinz, and other valve cover gaskets failed/leaked much sooner than "genuine mercedes" ones. If I can get +10-35k miles extra between change intervals, I'll buy the "mercedes" part happily. The gasket on the left side (well, right side if you're standing in front of the car looking at the engine) of the v12 engine bay is particularly irritating, so I'm happy with my decision.

"testing" a random no-name gasket to save $30 on a $150+K MSRP car seems quixotic to me. If it fails early, then what? you're taking the charge coolers, air box, ignition modules, rear intercooler piping on one side loose to replace them.... assuming it leaks somewhere visible and doesn't fill up a spark plug well, then wick up into a coil and short it out instead. it's gambling $30 vs hours of work. I'm good.

You know that Victor Reinz is the golden standard when it comes to gaskets?
Valve stem seals are also Victor Reinz, for example

As they are the only aftermarket option available for these cars, it is quite possible that they are also the oen

True, I'm simply reciting what I've read... like I said, several mentions of this on e55 amg, and other m113/k-having subforums. I'll pay a few extra $ to mitigate grunt work.
