Hi all,
I’ve recently carried out an oil and filter change. I took the opportunity to also change the sump gasket and re-seal the pressure sender (was a slight leak present). Prior to this work oil pressure was indicating normal (30 psi plus).
On restarting the engine oil pressure was indicating zero. I suspected I’d been over enthusiastic with the plumbers tape and the sender was no longer earthing against the engine block. I removed the sender and re-sealed ensuring not to overdo the tape. Now, as soon as I turn on the ignition (but not starting the engine) the pressure gauge goes straight to maximum 90 psi plus. Once the engine is started it still indicates maximum. I’m happy that the oil is circulating at a good pressure and the problem is with the sender. Any ideas what may be causing these symptoms?
Many thanks
