It COULD be a problem with the crankcase ventilation system. There's usually a PCV. (Positive Crankcase Ventilation) hose that connects to the air cleaner assembly from a valve cover. If you removed the hose and plugged the hole or put an old fashioned breather cap in it's place when you installed the aftermarket air cleaner assembly that's probably the problem. Without the PCV system working properly you'll get condensation in the engine from improper PCV air flow. This can mimic a blown head gasket. Hope that helps! Jim

Oil in the air cleaner assembly can be a sign of a malfunctioning PCV system too. Jim

So I bought it with the cold air intake from a high school kid that had no clue what the f he was doing . He replaced the radiator thinking it was bad when it was the water pump and put a smaller radiator in it so I've been picking up used parts to keep it going but it's starting to make a bigger dent in my wallet than I want to deal with

Oh boy! Well definitely check out the PCV system then before you condemn the engine. Make sure everything is hooked up correctly and replace the PCV valve. The PCV valve is only a few dollars. Jim
