Putting this one up for a mate of mine, who recently purchased a gt, basically im thinking that the engine is in need of a rebuild. Firstly there is alot of oil coming out of the breather and it is whistling, it is also breathing out of the dipstick, hes had a compression test done and two were running over 1 hundred, 1 was at 90 and the other 70, i reckon its shagged but he wanted me to ask you wise people on here first before he does a complete rebuild, is it likely to be anything else other than piston damage ect?
