Fellow dieselheads,

my recently-acquired 300DT has a faint noise that may be a bad exhaust manifold gasket.

It increases with throttle pressure, and nearly goes away at idle.

It also sounds like it is in the cylinder head area, so I doubt if it's a lower end issue. Oil pressure is ~1.8 bar at hot idle.

I haven't yet done a compression test to determine if it's a bad exhaust valve, assuming that the previous owner may have neglected valve adjustments-

I did a search of the entire diesel discussion and found no threads relating to exhaust valve or turbo gasket failure, so I'm tossing this out to all of you--

Has anyone on the forum ever had a burnt exhaust valve or failed turbo/exhaust manifold gasket?

Please advise,
