Landy issue
I have just done a service and replaced the oil, oil filter, air filter and fuel filter. All that might not be relevant but on starting her up all seemed fine except that I can hear a knocking / popping sound from the air intake. I've done some searching head gasket or associated seemed to come up on a regularly! This is what I've checked so far:
Defender 1995 300TDI
Linky to the popping sound here https://www.dropbox.com/s/u0dqix1qk605zip/Popping%20sound.m4a
Video of header tank here https://www.dropbox.com/s/j7tdbpmkidq3y6g/Header%20tank.MOV
Would appreciate any thoughts or other tests I could try. It had a new Turner engine in 2010 and has only done 14,000 miles so I'm hoping it's not the dreaded HG failure.
Cheers

- Oil - nice and clear no whitening etc
- Exhaust - puff of black at start up then nice and clear, only slight puff when hoofing it
- Header tank - No diesel smell and water / coolant seems clean, no white froth or bubbles - you can see water / coolant rushing into the tank when the engine is revved, I presume this is normal - no real pressure build up.
- Temperature - sits at half way most of the time only rises to 2/3 on a steep hill if I keep the speed up - running at idle and normal temp the top heater hose is still flexible.
- Engine - no obvious oil leak and it hardly uses any oil, the only obvious leak is a small amount from rocker cover gasket (on my to do list)
