Defender 300tdi engine info request

Hello Mates,

I made a similar request in the Defender forum but thought it be a good idea to seek info here too.

I recently bought a 97 300tdi Defender which is in great shape but the engine was suffering from lack of full care. She seems to be down on power but before playing around with anything on any engine, I like to know whats going on.

I would be purchasing a few gauges for the Landy including a tach, for both diagnostics and tuning.

Can you guys who know accurate values of the various stock engine pressures etc., of the Defender 300TDI please share?


Oil Pressure PSI

Oil Temp in Fahrenheit

Boost Pressure PSI

Exhaust Gas Temp (EGT)

Fuel pressure PSI

Water Temp in Fahrenheit

Idle RPM

and though it varies and not that important, your average shift RPM if you have a tach.


Thanks Mates.

Cheers.
