Hi all. Put my nanocom evo on and done a cylinder check at tickover. All cylinders read about 1 or 2 except cylinder 5 which seems to read -9. Anyone got any ideas. Motor starts and runs fine although a bit chuggy on takeoff. iiam still losing a little water and fear head gasket or water pump but just wondered if this could be an indicayer.

One cylinder out of balance, i'd investigate further in that direction. I usually see equal readings for all 5.

always cyl 5 wears out first due to the absence of glowplug on it ... so did mine too

Once I read, as long as the unbalance is below double digits (+/- 10) - then no problem ..

Comments anyone?

Mine jigger about +-2 on each pot but No5 is always a bit more twitchy until the engine warms up.

that's a bit exagerated, see the second page 10'th line of this document http://web.nanocom.it/download/DIAGNOSTIC FUNCTION OF THE TD5 ENGINE.pdf
