Loose timing chain on m271
I have a 2005 C230 with a M271 engine. I recently replaced the head gasket on the engine and am having problems keeping the timing chain from coming loose after a few hundred miles. I have replaced the tensioner but this has not worked. Next I will be replacing the chain, tensioner again, and slide rails. Are there any experienced techs out there who have some experience with this issue? Thanks in advance
