1995 Nissan 4wd hardbody v6 The rear camshaft seal was leaking so I pulled the old one out and now I can't seem to get the new one started. The engine is in the truck and there is not a lot of room to press it in. The seals aren't beveled and so it difficult to align it with the hole correctly. Ideas? Is there a difference between the front camshaft oil seal and the rear? I tried to use the face plate and the screws to press it in but because I can't see if it is aligned with the hole, I damaged the first one.
