I have used seafoam many times I think it is wonderful stuff, put a few ounces in the oil and run it no more then 50 miles is my personal recommendation, it will clean dirty gunky oil passages. Also be sure to use it in the vac system to clean the tops of the valves and the intake track from any and all oilly gunk. then put a small amount in the fuel tank it acts as both an injector cleaner and additional carbon deposit remover.
The problem with oil type air filters is too much oil (user error) will allow some of that oil to coat the maf sensor as its pulled through the system.
I believe I mentioned this before but the gunk in the air intake is from the pcv system not much you can do about it other then to make catch cans or just let it vent to atmosphere.

When was the last oil change before your oil change 1k miles ago? it may need a shorter oil change interval while it "cleans" up the engine.
Thank you for the advice. I already went out and bought a bottle of seafoam. The last oil changed was supposedly done right before I bought the car, but I didn't trust it, and sure enough when I changed the oil it was not great. It still had a decent consistency but it was pretty dark and I wanted it out. I Put in full synth 10w30 I believe. Don't remember the brand but I want to say valvoline. It's color is still very nice and I'm about 1500 miles in on it. It is draining slowly tho, so I'm keeping an eye on the levels. I'm not sure but it looks like the valve cover gaskets might be leaking. But there's definitely a considerable amount of oil leaking. The pan gets greased up real fast. I'm really unsure of where to take the car because I want someone who knows the SVX to work on it and if possible to have me there to observe and learn. That thing about oil lifters also seems like that could be the case. I'll have look into that. I'd like to adress the issue with the pcv but I have to worry about the trans and the engine Leaking first.
