Smoke...
Today I noticed that my car had a bad 90 degree hose on the drivers sidethat goes from the intake manifold to a hard line that runs under the Trottle body. I also noticed that one of the nutts on the egr valve was lose to I tightened it. Replaced the hose and tightened a nutt. Now im getting smoke coming fromback of manifold. Very light smoke. White.

It takes a little while for it to start smoking. If I have the engine runnin and I put my nose over the egr valve it is very strong. Just a light haze smoke but very pungent. Possible bad EGR?

The 90* hose he is talking about is the pcv elbow that goes to the PCV check valve on the driver's side of the intake manifold. The metal line that goes under the front of the TB is a vaccum line of some sort.
Does anyone have a diagram of the LT1 PCV system? Would ANYTHING in the PCV system cause the light smoke?

Well turns out the smoke is from a oil leak. Havent found where its comin from but its somewhere on drivers side and managed to spray on headerand most of the underside of the drivers side. The thing that scares me is that ther is only a couple of drops on the garage floor but I managed to go through almost a quart of oil ona 40 mile drive. Any Ideas?

I am trying to remember... is the timing gear pressure oiled? or gravity? I am thinking it's pressurized to get there, but the bulk of the work is via gravity.
Can you see if the oil is on the FRONT of the motor and getting on the belt?
I would carefully degrease the engine (simple green and a light hosing) and then add oil and dye to the system. Drive it around and hit it with the dye light. Autozone is selling a kit now that has the glasses and light for like $25.00. Seems like a good deal.
