Im going to try this forum since i havent had much luck in the V50 one but the motor is a 2.5T, I purchased it with a blown HG but running rather well actually, i replaced HG, water pump tensioner timing belt lapped valves and did valve stem seals, head did not seem warped upon inspection and was left alone. the failure was between the 2-3-4 cylinders and the owner obviously tried putting a few cans of repair your headgasket snake oil into it because the stuff was everywhere. cleaned out the best i i could. fired it up and it ran like a charm till about 3-5 minutes in it started blowing blue white/blue smoke out the pipes and began coughing and wheezing. shut the motor and hoooked up scanner, cylinder 5 misfire. cleared codes, checked wiring and found short to ignition coil, fixed it, next day started and same thing, ran great the its like something opens up in the motor and starts dumping oil on because again she coughed and stuppered to a stop. there are no bubbles coming from radiator, and the engine doesnt seem to even get very hot. i did have one issue when reassembling and that was the turbo return line i think. it was the aluminum tube going below the vvtsprockets to a nipple on the turbo top and to the center of the block. i could not source a replacement or afford one so i used a 22 inch section of 3/8 high pressure fuel line and ran it over the valve cover till i could get a proper replacement..is there a oil pressure valve or turbo valve that i need to clean out. the pcv system actually looked rather fresh and clean but is there a way to make sure it is. any help appreciated.
