BWC Posted March 5, 2017 Share Posted March 5, 2017 Hi all,I had a little scare today that my eagle eyed girlfriend spotted instantly in our 1600 K Series.I hope someone can help!With everything up to temperature as normal, the oil pressure gauge reads its normal low whilst idling, picks up to about 4 under load until about 2900 rpm and then the scare begins.At just below 3000 rpm the needle on the oil pressure gauge begins to wobble (a lot) and at 3000 rpm falls away to zero. reducing the revs back to 2900 rpm results in the oil pressure instantly returning to normal according to the gauge.Do you think the car is poorly or could the oil pressure gauge be telling me porkies? Is it possible that the revs are a coincidence? Many ThanksBen Link to comment Share on other sites More sharing options...

SM25T Posted March 5, 2017 Share Posted March 5, 2017 Assuming oil level is correct .... money on electrical sender failing. They do that a lot. Change it to a mechanical gauge with a capillary tube in place of the electrical sender. Link to comment Share on other sites More sharing options...
Roadsport06 Posted March 5, 2017 Share Posted March 5, 2017 As above. Also, do you have the foam baffle fitted in the sump? Link to comment Share on other sites More sharing options...
Brian Deacon Posted March 6, 2017 Share Posted March 6, 2017 Hi Ben. Mine did the same. Same engine. Changed to mechanical indication and it's been ok ever since. Bought mine from Merlin. Brian Link to comment Share on other sites More sharing options...
Sim Posted March 6, 2017 Share Posted March 6, 2017 The electrical sender is very exposed on the K and easily damaged by a simple knock. I did this twice in 2 weeks before I realised the plates at the entrance to the carpark at work were causing the damage.Caterham used to do a remote mounting kit for the sender to move it out of harms way. I've had no more trouble for the past 16 years simon Link to comment Share on other sites More sharing options...
John Vine Posted March 6, 2017 Share Posted March 6, 2017 The electrical sender is very exposed on the K...It's also very prone to engine vibration, the main cause of failure, IMHO. The remote mounting minimizes this as well.But I'd agree that the mechanical route is the way to go.JV Link to comment Share on other sites More sharing options...
