Because you can’t see it. The oil cooler on this engine is in the “V” of the engine, under the intake manifold and all the related plumbing. All you can see is the oil either gushing out off the back of the engine if the leak is external, or more commonly, oil in the coolant. A very common malady for this engine which involves pulling the heads to resolve. Parts are a minimum of about $1500 and Mercedes-only.
My (and Floyd’s) CL600s have this engine. Only way I would buy one is if I knew the oil cooler had been replaced. Mine has, it was done by the dealer and is listed on the VMI. -D > On Apr 20, 2023, at 11:32 AM, Andrew Strasfogel via Mercedes > <mercedes@okiebenz.com> wrote: > > Suspicious.
