Default 1988 RX Questions (MANY, MANY Questions...)

About one and a half months ago, I purchased a 1988 Subaru RX (1.8l, turbo, full time 4wd and locking diff.)

I purchased it as I needed a daily driver while I work on my Supra. Upon driving it and such, the first thing I noticed was lifter noise. I was directed to Dr.RX (Corky) and promptly asked him some questions, but as more have arisen, I thought I'd ask a larger audience.

First off, on the advice of many, I added MMO (Marvel Mystery Oil) to the oil of the RX in an attempt to quiet down the lifter noise some. It helped some but no huge change.

However, My biggest dilemma is this. Recently the oil pressure seemed to rise on start up. It used to hover ~50psi (on the stock gauge) on a cold morning, then it'd drop as it warmed up.
Now, it comes up to ~75 +/-5psi. I was told by the previous owner that it was time for an oil change, so I did one. Filter + Chevron 10W30 + 1 Bottle of MMO. This had no effect on the oil pressure. Also, it doesn't matter if the car has sat overnight 12+ hours, or whether it's between me arriving at work, and taking lunch after arriving. The pressure still goes high, then eventually settles down.

Ok, my next issue is this, smoking. When I pull up to a light sometimes after say exiting the freeway, I'll see smoke in the headlights. I've pulled over and checked it out, and I can't find squat. I can see smoke coming from what seems to be the front of the motor... I'm not smoking out the exhaust pipe, and I'm not leaving any puddles on my driveway. (few drips now and then, but not squat.) But, it sure smokes from the front of the motor. I'm a little confused as to what it could be... or how I would go about repairing it. The Flat-4 design is really new to me. I'm also seeing smoke coming off the downpipe (video clip) (which just could have been my brothers fault (he works at JiffyLube so I don't have to do them on my slanted driveway) but I'm not sure) and I'm seeing oil sprays on the underside of the hood.

Those are the major issues really. Other minor ones are I was wondering if the SOA Service manuals are online anywhere for my vehicle, or if not where I might find them.
Anywho, thanks for all the help!
