aldridgen Posted April 24, 2002 Share Posted April 24, 2002 After pulling in to work this afternoon I noticed the oil pressure starting to rise and it flickered around the 8 bar mark. At around the same time the radiator fan came on. Everything sounded healthy enough and there was plenty of oil in the dry sump bell-housing. Is this a technical problem which will allow me to drive home safely or could it be something more serious? Yours in ignorance, Nick. Link to comment Share on other sites More sharing options...
F355GTS Posted April 24, 2002 Share Posted April 24, 2002 Did it go down again after the fan cut in? sounds like you might have a wiring problem and it's measuring the water temp????? Mark Edited by - F355GTS on 24 Apr 2002 17:38:42 Link to comment Share on other sites More sharing options...
New Barbie Posted April 24, 2002 Share Posted April 24, 2002 Sounds to me like the same. Apologies in advance if this is a daft question to you, but you do get an initial reading which is quite high from the engine cold - say around 4to5 bar ?

Blatman Posted April 24, 2002 Share Posted April 24, 2002 What enginequestion.gif Wiring does sound the likely suspect. Check the earth under the dash (nearside I think). Do you have a dual use guage, utilising the oil pressure guage as an oil temp guage. If so, make sure you haven't knocked the switch onto oil temp reading. Oh yeah, check the sender too, to eliminate that from the equation. They can be unreliable............

CHRIS CLARK Posted April 24, 2002 Share Posted April 24, 2002 The sender works by running current through itself to earth. Higher pressure = less resistance. When fan came on did the vibration cause an area of poor wiring to short to earth (Chassis) if only quickly? This would give a full scale deflection!!!

aldridgen Posted April 30, 2002 Author Share Posted April 30, 2002 Thanks for all your replies. It does appear to be the oil pressure sender. Is this a specific Caterham part or a standard VX one? (Car is 1993 VX 16V with dry sump by the way) Thanks, Nick. Link to comment Share on other sites More sharing options...
