94 Pathfinder manifold studs - warrantee extended??

My solution is money talks- Nissan will never sell a car to me again. More than exhaust manifolds- I have sunk $4000 this year alone on my Pathy and now the rear main is leaking (another $1k job).

I have a 92 with 95,000. Nissan did the driver's side plus 4 bolts for $650 at the 92k mark. Now at 95k the passenger side is leaking. A local garage is quoting around $310-490 (depends on number of studs); still saving my money. I never imagined I may need to fix it again around 125k miles?

Thanks to all for the great info- it helps.

Other than the passenger side exhaust manifold (which I never fixed), I never had to replace ANYTHING on my '95 Hardbody except front brake pads, spark plugs and air filter. I sold it and bourght a 2004 Frontier crew cab, long bed.
