So Iv'e been stalking several defender forums and reading many horror stories of issues w/ the early 2.5TD engines. Of specific interest is the issue of oil blowing into the air filter via the valve cover breather hose that connects to the air filter housing inlet. I read a couple of posts that suggested relocating the breather hose from the air filter housing inlet to the air filter housing outlet hose going to the turbo as a fix. Has anyone heard of or done this? Any thoughts?
