I swapped out my ISV this evening, re-strapped the intercooler, and tightened some other hose clamps. I started the car and backed out of the driveway and went down the road a little, looked in my rear view and saw a huge cloud of smoke in front of my house! I turned around, checked my rear view again, no more smoke. When I pulled into the driveway, more smoke started pouring out of the back of the car! I killed the engine, opened the hood and saw quite a mess. Oil coming from the stud holes in the valve cover, a huge puddle of oil in the duck pond of the intake manifold, the center section of the turbo covered with oil... ARGH!
See, a few weeks ago I changed out my breather hoses, and in the process, I wrecked the little plastic tube that comes out of the intake boot. I pulled the remnants out and used a smaller diameter rubber fuel hose to join the two, with hose clamps of course. Well, one of the hose clamps I tightened was one on that particular junction. Seems I tightened it way too tight without thinking. I need to get to the store and buy more Berrymans to clean that mess under the hood, then I'll also be able to tell if any of the seals are blown out for good. Let's cross our fingers and hope they aren't!

Check for oil puddles by the bell housing for a blown rear seal. Also check the front for the crank and cam seals.
Sounds like you found your cause. The plastic nipple is 3/4" dia. The older type44's used a metal tube.
You might be able to find one at a junk yard, otherwise try inserting a piece of 3/4" outer dia. tube.
Sounds like your valve cover gasket gave up. Replace and you should be fine.
You can use a gallon of mineral spirits from Home Depot to wash off the oil. Might be cheaper than cans of engine degreaser.

Good advice on checking the seals. One thing I would add though, or remove depending on your point of veiw. If you never want this problem to happen again, you should plug up the hole in the intake boot. Then go to the local cheap auto parts store(Checker, Schucks, Kragen, Auto Zone, whatever) and buy a cheesy chrome breather filter with a 3/4" barb on the end and a 18" section of 3/4" breather hose. Connect the 3/4" hose to the valve cover barb and the other end to the breather filter. I placed the filter next to the barb on the intake boot, between the fuel lines, intake manifold, and the boot itself. If I had a digital camera I would just post a picture. It may not be technically legal, but it will eliminate any oil in the intake issues.
When I rebuilt my top end there must have been a 1/8" layer of sludge baked onto the intake runners (inside the intake manifold). My breather system was a bit restricted, but with this type of system, oil vapor will inevitably condensate and drip into the intake. I plan to make an oil catch can and install a K&N breather filter, but the $6.00 solution from Schucks works for now. No more sucking oil. I got the idea by reading a lot of old posts on this forum, these guys rock! Thanx for all of the ideas guy's ;)
If we didn't pass on our knowledge and experience, it would be worthless to have ever learned it in the first place. Thanx again guys. J.B.

Have to agree with you on the ddirty intake syndrome.Everything including the intercooler gets it.not good.
About 10 years ago i found a really good pcv oil separating system.I no longer have it but can attest that it did that job really well.
It used a mason jar as the catch can,the pcv hose
had to be cut to install.two 3\4" fittings.on the intake for this filter inside the catch can was a filter media which i believe may have been zeolite(little white balls).When you'd crack the throttle you would see a cloud be created.And catch oil it did.Gonna have to make another one.
It would save so many headaches like cracked lines plugged intercoolers,dirty air temp sensor,
Restricted intakes.I think it would even work without the filter in it.I'll post pictures when i get it done.

Was it like this thing:
Looks like the first versions they made used a glass jar, now they've gone to a nicer, manufactured look.
I'm still debating whether or not to get one.

Do a search on "oil catch can" on ebay.
You'll get some less expensive aluminum ones.
The Condensator looks impressive, but $200 is premium. It seems to resemble an air compressor line filter/water separator.
Some people are using those as a catcher. But I'd get a larger capacity one than those little Cambell-hausfeld jobs.

$250? Nah, they are $199 Canadian, so around $115 US or so.
