HELP! Let me explain. Lol
Ok, so I picked up another disco 2. I have attached a video. Now it may be the head gasket but before we get there hear me out. The motor was replaced in 22, then it was repaired due to an exhaust leak? So, the gem of a mechanic says the exhaust manifold didn’t line up so he double gasketed it. Please send me some advice before I rip the heads off! Not sure if the video posted or why it isn’t posting

My manifolds to the head are also double gasketed and from what I understand, that's normal. I'm putting heads back on and going to also double gasket in the same place they already were.
With it cold, put your smoke tester into an O2 sensor hole and see if it's just leaking at gasket or cracked. I use a tire valve stem backwards to plug up O2 sensor port when smoking exhaust.

what I don’t understand is why they wouldn’t line up? Where you able to see the video?

I don't see a video. Sometimes it's easier to put it on YouTube and share the link?
Sometimes things don't line up, especially on our 20 year old vehicles, wear, rust, unreported damage, bashing around on crane when removing old engine, someone getting flat rate and not having time to adjust forever, not-perfect new parts that kind of but not really fit
Someone with more land Rover experience might have better information on the double gasket. But I'd smoke to find exhaust leak first and do my own diag before spending money

It sounds like either an upper engine tap on that side or an exhaust leak, you're right. When it's running can you feel air chuffing around manifold?
Can get a scope in a spark plug hole to see if a valve is flapping about or maybe easier to just pull off lower intake and feel for play in the rods?

will check tonight. Thank you so much for the input. Everyone else has just been saying without them knowing or hearing me out that it’s a head gasket bc it’s a 4.0 Land Rover lol
