So, I seem to have located my oil leak.I have oil leaking from driverside 3"hose that connects the manifold to the spider.The hose looks fine.I've taken it off twice cleaned an inspected it.Is it a normal path for oil?What is a ccv mod and why do people perform it?How can I stop the leak?Will this mod help?
I accidentally posted or jacked another thread.It seems like if I replaced the hose the problem should go away.Why is this happening after 100k miles?Is it a bad hose or is something else causing it to leak?
You'll still have the oil laden fumes being introduced into the Turbo, Intake, Intercooler, piping, and all those 3" couplings. As the engine gets more miles, use really, the amount of blow-by (combustion gases getting past the rings) increases. This greater volume ends up getting pushed into the intake system, through the CCV hose between the filter and turbo inlet, and carrying engine oil "mist" with it .
It's only going to get worse, rot those IC couplers (3" hoses) and continue to give you trouble. Do the CCV mod and eliminate the cause
