I've been busy recently and haven't been able to work on my car much, but this last weekend I was able to perform a compression test on the cylinders and found that #4 is very low on compression. I'm going to perform a leakdown test on it when I can get the tool. Although I may need to tear the engine apart in the end, if it's the intake or exhaust port that is leaking then I may put through some seafoam first just to see if that clears things up, but if it's not the valves then it's probably the rings. If the rings are the problem, then I'm going to have to make a big decision about what I want to do with this car since that's a lot more work and $$$ to fix.
