Three problems related to manifold/header/muffler/tail pipe have been reported for the 1997 Land Rover Discovery. The most recently reported issues are listed below.
Left exhaust manifold cracked, right exhaust manifold broken in 2! cast iron exhaust manifold both diagnosed as cracked - I replaced worse of 2 then better one broke. Engine block aluminum - creep/fatigue failure due to thermal expansion rates of manifold versus block should be investigated. I believe warrants a recall - especially in CA with tight smog limits.
While driving a loud noise came from under the hood. The noise occurred because the manifold had a hair line crack. A manufacturer's improvement campaign was issued. The manufacturer indicated that the vehicle's VIN was 1 digit off, thus not covered by the warranty.
While driving vehicle made a loud noise. The vehicle was taken to the dealer. The dealer determined that there was a hairline crack in the manifold which caused the loud noise.
