Here's the biggest problem with this motor
. There's no zinc. As a result the oil
cooler which is brass & aluminum
dissolves. This will result in a coolant and/or oil leak
. You can't see it because it's behind the heat exchanger
which is built of the same materials & can also suffer from the same corrosion
although this appears to be rarer. The turbo charger
also tends to rust on the inside making rebuilding difficult or impossible. It's important that the rubber washers are replaced every time you take any part of the coolant system apart because they don't reseal well. Another problem is the intake silencer which has a plastic housing with a foam interior
that can't be changed. You have to replace the whole thing & if you don't parts
or all of the foam can be sucked into the turbo charger
. Also be sure & check the motor
mounts on the starboard side.
I may have misspoken when I said the lack of a zinc is the biggest problem with this engine. The biggest problem is the price
. The oil
cooler is more the $1,700 & the turbo charger & heat exchanger are both around $3,000. The good news is that the motor itself is reliable & parts are available. An aftermarket oil cooler is usually installed although it does require some ingenuity.
