So I had my 99 GTP looked at in December because the coolant elbows were shot, from a quick look they said lower intake but after getting under the hood they said elbows. They also told me coolant was in my oil and I was losing lubrication in my engine. They showed me the oil cap and it was brown and crusty on top and said that was coolant. Made sense. So I changed my oil today and the oil cap looked the same as it did before I had the elbows and flush done... So my question is can coolant even get into your oil through the elbows?? Or is brown crusty crap on the cap normal?
