In looking for an answer as to why our 2005 Boom Lift with a Duetz 3-cylinder diesel engine recently started using oil. it has 5400 hours. we have had several people look at it and have the same number of opinions as to why the engine is using oil.
While researching we came across this site that had posts regarding this problem dated back to 2011.
From that forum my question is, is there a PVC valve that could be blocked and if so, how do I clear it.
