To give you some background info this car had sat for 3 years before I bought it. Ive done the work required to get it on the road but have now ran into a few more issues. First off after 5k revs on full boost I get a misfire. I'm thinking its most likely the plugs as they look past there best but is there anything else obvious to check. Boost leaks etc? Secondly, after cruising at a set speed, if you lift off for maybe 5 seconds or more then accelerate again i get a puff of blue smoke. Ive checked the turbo and it does have some side to side play however no in and out movement at all. No excessive oil in breather and plugs arent covered in oil. Have yet to do a compression test. Any help appreciated
