This car is a beautiful, luxurious beast. Its owner loves to drive it fast. The valve stem seals were a good 1 to 2 mm off the stems, producing an incredible quantity of smoke out of the tail pipes.
The engine in this car was originally designed for the C-Coupe from the early 2000s. That was a port-injected, naturally aspirated affair. Now they’ve bolted on a vacuum pump to one cam, a high pressure fuel pump to the other cam, beefed up the timing chain to more than twice its original strength, and put a turbo on it.
The intake manifold had to be removed from this engine for repair.
The “tumble flap” intake control rods are made of plastic and commonly break after a while. Nothing unusual there.
If you’re getting the occasional engine misfire and no one can figure it out, maybe it’s your engine mounts.
