Fused... I cant get them off... don't know what to do... and I'm just talking about on the exhaust its self not the manifold or anything. I sprayed them with pb blaster and I'm gonna wait and try again some other time...

yeah was kind of afraid of that. I have no choice but to do it myself though... I have like no money but like i said i can get parts really cheap and I have a work shop to myself to use to do everything... Im just very inexperienced and kind of afraid of going out and taking the engine out... can i replace the headers without taking the engine out? i have the exhaust manifold gaskets on the way... and i have all of these gaskets already so I'm gonna try to replace those sunday.

Here is a video of the sound sorry for vid quality its from my android phone...

I meant he said it would get rid of the sound if its a lifter... (because most likely it wasn't getting oil upon start up) In any case im going to do an oil change tonight and use gunk engine flush then use 5w-30 2.8 quarts and 1 quart of Lucas oil stabilizer see what that does... then I will replace all the exhaust gaskets and tomorrow maybe the exhaust manifold gasket... Also no to the check engine light last time I checked.

My 1995 Nissan pathfinder is making a funny sound (going to try to post video tonight) but for now ill try to describe it. Its a fluttering whistle ticking that gets louder/worse with increase on rpm also gets worse if im going down a decline in gear without giving gas(under load?) Also this sound goes away over long trips or when warmed up? Started very slightly at first Some say its a lifter? But dohc doesn't have lifters right? Others say exhaust leak? Not sure... but I think I have read a lot of people saying an exhaust manifold gasket leak? So... a friend has said to do an oil change use thinner oil and use Lucas he said it will quiet right up. But if its the gasket... I was wondering if some one would give me a complete list of items needed for this gasket replacement? Would help a ton!
