Sea Foam? Auto Zone?

Hello All.. New around here, but you'll be seeing more of me... Thanks in advance- '92 Loyale, AWD, 5 speed, 125K Bought the car from auction, so I don't know about the maintenance history, but the problem is a lifter tick. When the car is warm it goes away, and the thinner the oil I use the faster the tick goes away (<10 min with 10/30). Yesterday I pulled out a Quart and replaced it with the Lucas oil stabilizer (molassas) the tick didn't go away untill about 20 minutes of driving, then I shut the car off and came back to it <10 minutes later, no tick at start up but then it came back within 3-5 minutes of driving. I have already purchased the new lifter, and all assoc. gaskets, and the job doesn't look to hard, according to the Chilton's. Maybe I'm over thinking this but if a lifter is crushed, won't it stay compressed...Is oil pressure a problem with these cars, or possibly some sort of oil drain port that is getting clogged ????. Like I said, I am new to the Suby family, so any info would be apreciated, concerning common problems, high fail items, or what preventive maintenance I should do while I have the valve covers and oil pan off.
