Default Oil everywhere, suspect: supercharger

Ok, so we tore down the 96 's' and found that the spark plugs are drenched with oil, the air system (intercoolers and pipes) have oil all inside them. we did a compression check, only getting to three of the six plugsbecause of the amount of time we had, the first front 3 where, 130,95,130, and considering there is no rod knock when the car is running and starts right up (so i don't think its the bottem end, like a cracked cylc wall or something). so we came to the conclusion that the supercharger is the cause, if not, what is? what can cause such a problem with all this oil?? headgasket? regardless the top end is getting takin off asap, if need be, i can replace the supercharger, which i heard are hard to find now a days, if not how hard is it to throw a new manifold on there, wire and fab up a turbo? i got a couple mitsu turbos laying around here

Default RE: Oil everywhere, suspect: supercharger

My car is a 96 "s" 127 k miles (sounds strong and starts like a dream..... with lots of oil everywhere)

From whatI read, themost reliable option is to purchase arebuilt s/c whichis going to run $1,700 - $2,000dollars(exchange). My guess isthes/c is going out and the valves have to be reworked. For oil in the boot areas look at the valve cover gaskets.

FYI - My compression test results
#1 180# (oil ran down into cylinder when I pulled the plug to install the tester)
#2 135#
#3 120#
#4 90#
#5 135#
#6 135#

Sounds like we have the same problems .................
