I'll quote from an article i saw at http://www.glencoyne.co.uk/enghist.htm
2495cc turbodiesel, overhead valve, type 19J: Given the strength and
reliability of the 2.5 diesel, you can understand why Land Rover thought it
would cope with turbocharging, but the result was a warranty nightmare.
2.5TDs can fail in any number of ways, but the most common seems to be
internal cracks developing in the cylinder block. This gives the same
symptoms as a blown head gasket or cracked cylinder head, but is not
repairable. Due to a defective design of crankcase breather, these engines
also tend to dump large amounts of engine oil into the air filter housing,
which turns the paper air filter into a soggy black lump. This in turn
leads to oil being drawn into the air intake, causing the engine to 'run
away' and self-destruct.
that is a little worrying don't you think? time to modify the breather I
reckon and be certain you don't overfill the sump
