I have a 94 850 Non Turbo with 180K thats pushing oil
out the oil filler cap. I replaced the cap
gasket and still have the leak. I'm guessing
its a high pressure crankcase situation ?
I noticed a 1/2 chrome line thats coming from
the rear of the head to a metal cylinder that located
under the top motor mount. Is that something I should
be looking at. Thanks in advance, Mickey

    If you don't fix the crancase pressure you will blow the rear cam seal or the rear main seal or both. First, check the PCV and make sure the lines are clear and the screen is tossed in the garbage.

    You might have to have the oil separator replaced along with both lines. It is a reasonable hard DIY, but a good excuse to clean the throttle body and get a new intake manifold gasket while you are at it.

    Now that the weather is getting nicer, knuckles don't hurt as much.
