RE: hard cold start / PCV oil loss
Remove the duct that connects the intercooler to the intake/throttle manifold
(easy). It's a short flexible hose about 4-5" long and is corrugated with metal
rings around it. Carefully look at the BOTTOM of this hose. You can't see this
when installed. It's VERY likely you will find a hole or a tear. Depending on
how this tear re-seals will determine how your engine will run. If you see
drippies from under this area, it's a likely clue. A tear here will also
reduce your turbo boost. Oil in these tubes/pipes is kinda normal.
Also check all of the crankcase vent hoses. They split and collapse easily and
have the same (or worse) effect as a leaky dipstick. Sometimes these hoses
split and the engine will be almost impossible to start. When these hoses get
warm and goo-ie, they can re-seal themselves and things seem normal again.
Especially check the hose that connects from right side of the crankcase to a
place toward the back of the valve cover (and the other hoses that connect
here). I'm on my 3rd set of these stupid hoses. If you have an 87 and these
haven't been replaced, I guarantee they are NFG.
