Hi All,

So I recently got an E70 30d which I knew would need some work, first off there was an oil leak. I removed the bottom trays and oil appeared to be around sump but of course you want to find the highest spot so it appeared to go around the bell housing and I think the final highest spot was just at the back of the valve cover by an electrical connector?.. I find it a tad strange however that it only seems to leak around by the corner, I've done other videos and noticed none by the turbo or anything.

This is what we're looking at:






Second issue is diesel is leaking from an injector but I'm not sure how to test where its leaking (return line etc) is it also possible to have worn O-Rings on the body of the injector and have fuel come back up the head?
