Irratic Oil Temp Gauge

[C J R]

Needle on the aftermarket Oil temp gauge (Mugen) \'flicking\' about when driving.
Any idea\'s what might cause this to happen ?
 
Thanks

Check the connection into the engine block mate, under passenger side of engine. The OEM 7 gauge is pants, if you want correct readings then change to say a SPA Duel Oil pressure/temp one. HTH.

Chances are it\'s a dodgy earth somewhere. Either on the gauge, or, if it\'s an electrical type with a sender, the try earting the sender to a good solid earth point - best way (if the sender doesn\'t have an eart point)  is to put a jubilee clip around the sender, and run a wire from that to the chassis/engine block Some senders rely on earthing via the threads to the block, which isn\'t always that great if you installed the sender with PTFE to stop it leaking
