So I blew my ko4 recently. I replaced the turbo, cleaned out the intercooler and all of the intercooler piping, but the car is still smoking. I figured it is still smoking because of all the oil and coolant got into the exhaust when the seals blew. I checked the oil level a few times and it remains the same, so the car is not burning new oil. My question is, how can I clean out the exhaust and other parts of the engine that have the oil caked up inside? It's just really anoying that it's smoking. Would a couple of seafoam applications help? Would it be ok to use the seafoam on a brand new turbo? Let me know what you think. Thanks.
