P38A coolant loss

Ahh the dreaded coolant loss!

First of all there is no smoke, water in the oil or overheating it just seems to be disappering slowly!

One thing i've noticed is if i release the expansion tank cap after a drive the coolant will rise.

The engine doesn't knock or run badly there is plenty of power!

Just at a loss tbf!

Check the carpet on,in the front right foot well ....Seal to heater maybe ,Been covered many times..

Oh i did the matrix o rings a few weeks ago no leaks from there.

Try UV dye in the coolant and then check the dipstick after a 1000 miles or so with a UV torch.

I did my matrix o rings... twice.. turns out it was the matrix core..

that was the month after I did my HG because number 7 was leaking into the chamber..

if you want to see if its the HG, pull all the plugs out.. if the HG has gone, you'll see a steam cleaned spark plug

Thanks ukadamwest

Thats the usual suspect. Replace with genuine LR & check the surface of the throttle body plate as they have a tendency to leak again PDQ.
