Ok my mistake I thought we were still chasing the Oil spray.

If it's Valves you can hear it in either the exhaust or the intake if it's rings you can hear it in the crankcase when you remove the dipstick or oil cap.

The other thing you might find/see from the leakdown is if it pressurises the crankcase the leak may become evident.

Needs to be done with the engine warm though.

... engine warm? lol can I just put a griddle under neat the oil pan? Guess I can slap on the timing belt w/o the cover on. no coolant should warm up faster right?

Would be better with coolant or even straight water and get it to operating temp before the test.

Well bad news.. I called all the napas/autozones/kragans/pepboys around. and no one has a freakin' leak down tester. Hell I had to explain what and how it was used to a couple of people. "ohh.. you mean a compression tester"... no ditz. I got one on order through napa. but due to holiday won't b e here till wednesday. :( so in the interum... any other paths?

Can you do a set of cliffnotes of what it's doing and what you've tried so far?

I have a lot on my plate at the moment so am finding it hard to give your problem the attention it needs due to the rambling nature of the thread.

Cliffnotes:

* Tried getting a stable tune, couldn't
*reasoned the lack of a stock PCV system was the Culprit

*Installed a PCV System as ripped off of your setup

*Got a good tune. Stable idle, good cruise both about 14.1 AFRs
*Drove 5 Miles on tune. Decided to do a hard pull.
*Took the car to about 8 psi in 2nd and shifted to 3rd to coast.
*Car started smoking horrible and wouldn't stop smoking the 5 miles home
*Got home popped the hood. and oil all over the engine bay
* A clear horizontal streak under the hood right about where timing cover was
*oil all over the acc. belts, fan/shroud is soaked
*figured a seal blew due to some change in the PCV system maybe
*after sitting for a day there is a mark on my CARpet that dripped about halfway down the length of my car. but beginning of the leak is to spread to pin point anything.
*pulled radiator/fan front timing cover off.. Not much oil INSIDE the timing cover, less oil on timing belt then acc belts. no evidence of leaks from any seals. (main/oilpump/cams)

Sorry I couldn't be of anymore help. Is the big hose from the driver's side cam cover to the block clear?

The only other things to do is a compression test and leak down test. Even then, there should be sufficient PCV flow to prevent blowing a seal.

Is the line of spray in line with either the AC Compressor or the PwrSteer pump?

I've looked at that a number of times. Even closed the hood and tried to peer in. the problem is. the pattern or Line is thick enough It easily covers all 3 belts. (timing, p/s, alt, i do NOT have A/C) but it looks like the primary BODY of the spray covers the width of the PS and alt belt.
as I mentioned both belts were pretty saturated w/ oil. the bottom lefft of the alternator had what looked like bits of sludge (similar to what you'd find in the bottom of your oil pan) slung on it. and thats whats got me the most puzzled.

I think tomorrow I"ll put the belts on. start the car and let it warm up and see if I can see any visable leaks after I clean everything off.

Was this engine rebuilt...i.e. the front timing cover removed?

Reason I ask, was the plug for the main oil channel on the front of the block, under the timing cover installed correctly?

Is the inside of the front of the damper wet?

I think the way you worded it got me. But if your talking right where the Crank bolt is.. Yes there was oil in there.

If that plug wasn't fitted you'd have pretty well 0.00psi Oil pressure ;)

But if it's leaking it WILL leak to the outside world as it's behind the wing on the timing case (green circle) and that part of the case is outside the gasket.

It wouldn't explain the inside front of the damper being wet though.
