Hi Guys! I'm a Subaru Noob with a question about my 83 GL Wagon. I got this car as a freebie, with the intention of fixing it. The front cylinder on the drivers side had severely low compression (60 as compared to 170 on the other 3, according to P/O). Wet test brought it up to about 90. P/O is a fairly competent mechanic and thought the rings on this cylinder were gone. My question is, how likely is his diagnosis to be correct, or should I look for other issues? Engine is in car with the head pulled, and access plug removed from behind water pump, so will I have to remove the engine no matter what the diagnosis, or can I R&R the rings in-frame? Thanks for any help.....
