Hello guys, I've put a lot into my 95 Pathfinder XE recently and I'm thinking it still has a blown head gasket and or warped head. I'm looking for info to verify if it is just the gasket, if it has a warped head also, or even worse. I recently had the front cv joints and starter replaced. I then replaced a busted window, door handle, and both front window motors myself. It then started overheating and making noises so I replaced the waterpump, timing belt, and thermostat myself. It still overheats although it does not say it is getting hot. It did before. As I replaced the above items I noticed there was a bit of oil behind the timing cover. I have burped the cooling system and as it warms up it does start to get pressure and the overflow tank bubbles. There is white smoke from the exhaust and moisture. There still seems to be some oil leaking somewhere behind the timing cover. it's at 200,000 and I don't want to toss much more money into it. I don't know tons about cars but am kinda handy. I haven't been able to find much info on how to replace the head gasket/header and things to look for. Any help is appreciated.
