jord294 92 Posted July 9, 2008 hi people i've recently fitted another 1.9 engine into my 205 gti. the engine had had a full rebuild, and has only done about 3.5k miles, 500 miles of that is with me. i had it rolling roaded at skip browns, and it pulls well. 128bhp at the wheels (fitted with piper 270 cam and pulley) now the problem i have is that when it revs past 4k rpm, it puffs out a wisp of blue smoke. it is using a little oil it runs perfect otherwise. it revs freely, has good fuel economy (even with a 1.6 box), and doesn't get hot or use water. anyone got any ideas please? ta very much Share this post Link to post Share on other sites
DamirGTI 342 Posted July 9, 2008 Valve guides maybe or badly installed steam seals .. oil can be sucked down past the valve guides/steam seals under presence of high vacuum inside the inlet tract .. Can you spot any oil puddles inside the inlet manifold , around the Tb butterfly and inside the main Tb to AFM air feed pipe ? Rgs ! Damir Share this post Link to post Share on other sites
