I recently got my valve cover chromed. The shop took out the plate at the bottom of the valve cover without asking me chromed the valve cover and then replaced it. After driving on day there is oil coming from the cover. I took it to a nissan dealer and he said there is a problem with the plate under the valve cover. I am in the philippines and they do not have my type altima here. The guy is asking me if the valve cover is supposed to have a hole in it . I think under the plate is where he is talking about. Heck, I dont know. Can anyone answer that question for me or tell me where I can find a picture of a valve cover with out the plate underneath it. I have a 1999 Nissan Altima. Manual.
