Hi guys I'm after a bit of advise after discovering on oil leak from the underside of my turbo. It appears to be coming from the exhaust turbine housing not the drain flange or pipework. I've read up a little regarding this issue and some say its caused by the oil level being to high inside the bearing housing allowing oil to seep past the oil ring. I have standard pcv setup plumbed in no catch tank. Could this be down to crankcase pressure preventing the oil draining back into the sump at a quick enough rate on boost? Thought I'd ask you lot before I get my hands dirty again lol. Many thanks in advance. Oh and merry Xmas to you all!!!
