I have just got my 'van back from the
garage with its new engine and, hopefully, the problem solved. The
garage says that water was getting into the engine via a leaking
connection in the air intake pipework, where the pipe from the bottom
of the airfilter to the turbocharger has a connection coming in from
the cylinderhead cover. Water getting in under the bonnet collects on
top of the air filter then runs down onto this joint. For some
reason, after 7 years and 63,000 miles this joint started leaking,
allowing the water to be sucked into the turbocharger.
Anyone know any way to reduce/eliminate
this water ingress under the bonnet? does it happen on new Boxers?
Does it happen on Fiat Ducatos? If not, why not
Hi, I was intrigued by the description of
your fault and reasons given by the garage. I immediately went to
have a look at my Peugeot Boxer. I found the pipe mentioned. It comes
from the oil filler, acting as an engine oil breather, then being fed
back into the turbo input pipe, after the air filter, which is fed
directly to the turbo. This connection is a bayonet fitting, which
requires a quarter turn to lock. This pipe is not supported properly
and is secured with a jubilee clip, I found that my pipe was ready to
be pulled out due to the vibration from the engine and oil deposits.
My cure is to fit a support to this pipe to ensure there was no
vibration at the joint into the air filter pipe.
Regarding water into the engine
compartment. I found that leaves had lain in the water well, which
normally drains into the heater air input, stopping this action. The
water would then overflow on to the top of the airfilter. There is a
drain hole at the base of the air filter container to ensure no water
drains into the turbo input. I wonder if this hole was blocked. This
drain hole can be seen in a picture at: www.ourwanderer.org/peug9.htm
