I started up my 1990 964 after a 12 month layup with very serious smoke everywhere! I assume it's something to do with the 'air oil separator'. My question , where is it located, is it a DIY repair, can it do serious damage, is there a mod' to stop this happening again as it seems to be a serious design fault? I don't think it's burn off as the engine was run for approx ten minutes with smoke getting worse. I've heard of AOS failure where oil is sucked into the inlet manifold!
