Hello to all

I have recently purchased this 940. After doing some work to it, I checked and cleaned out the PCV lines From the Turbo to the breather box, including the small manifold fitting and hose. There was no flame trap as to say like on my older 85 245. This just had the hose from the turbo area over the valve cover through a small s-shaped hose w/plastic fitting " small line to the intake, large hose to the breather box". Breather box was clean, all hoses were respectable and no collapsed hoses. I still have oil blow by at the turbo drain line at the block and the oil fill cap still bounces around.
Any other places to check out?

Thanks
