Ok from the beginning, I bought this car last summer. Ever since I bought it, it would leave a small puddle of coolant on the ground after driving. No big deal, it's 20 years old. Eventually it got bigger and bigger and a few weeks ago it basically started pouring out coolant from somewhere. I changed the water pump, thermostat housing, and all hoses thinking that had to be it, even though I never really pinpointed the problem. That did nothing. I first started to suspect the timing cover, because the area is soaked in coolant. But after getting under the car I realized that it's just collecting there and the actual leak has to be coming from further back in the engine. All I can tell for sure is that coolant is flowing down the right side of the oil pan and coming down by where the oil filter is. I have used compressed air to dry the area and started pouring water into the thermostat housing and within 15 seconds I see it coming down the right side of the oil pan at a rate of about half as fast as I'm putting it in. I can also see on the front of the motor where coolant has been going down the driver side cylinder head, but can't tell if it's actually coming from the head. I have no cross contamination in my oil and when it was running there wasn't any smoke out the exhaust that I noticed. The freeze plugs on the block are also dry. Could lower intake gaskets cause a leak that bad? This isn't just a drippy leak, it's a small steady stream. Could a head gasket cause a coolant leak but no cross contamination? I'm at a loss here and getting really frustrated. Thank you for any help.
