Massive oil consumption suddenly (99 Forester L)
I am new to this forum (and to newer Subarus as well). We recently bought a 99 Forester L with a bad clutch. I replaced the clutch and all is well there. However, my wife has put about a thousand miles on it since we got it, and 3 times I have checked the oil and there was none on the dipstick! I will had 3-4 quarts and check it 4 or 5 days later and it will be almost empty again. I checked for any leaks underneath and found none. Just a few weeks ago I noticed that when first starting the car up it smokes quite a bit (The smoke very light grey bordering on white, and smells like burning oil). After the car is fully warmed up it stops smoking for the most part. If you shut the car off and let it sit for a hour or so, and restart it, it smokes just as bad. The CEL is illuminated as well. I checked the codes and it had a cyl #4 and #3 Misfire. The plugs are all brand new, as are the wires. The PCV is also new. I suspect that the headgaskets may be done, and was prepared for the repair given the mileage and what I have read about these cars. What I am trying to figure out is if my rings may be shot as well. I am planning on performing a compression test and more than likely a leak down test as well to try and pinpoint the problem. I know what to look for in terms of a headgasket failure, but what are the signs for bad rings? What are exceptable figures for compression and leakage (99 SOHC EJ25 with 110K)
I really like this car even with the problems (Bought it very cheap) and would like to keep it in the family for some time, as it is replacing our old 88 GL wagon which finally succumbed to years of salty roads.
Any advice would be wonderful!
