Hi - I'm seeking advice on the least expensive alternatives to get my car back running. I'm getting smoke out the tailpipes and very rough idle. I pulled the plugs and one of them was coated in oil and the catch can was full of yellowish oil (possibly mixed with coolant). The car will be sitting on the driveway waiting to be fixed. I want to keep the 2.0 LNF motor so I'm looking to see if others have any experience getting motor rebuilt, replacing with a rebuilt motor or used low mileage motor. Thanks in advance. I'm out of warranty by the way.
