Richards 7 Posted June 19, 2007 Share Posted June 19, 2007 Wet sump 1.8 K series...... have searched for this but not found the answer so........ on start up about mid range on the oil pressure gauge (4??) but once thoroughly warmed the needle oscillates usually just above the red...is this normal and if not should I worry a lot or little. Additionally a little sticker on the end of the cover near the dipstick says check oil with engine running and at operating temperature. This is what I now do, however last weekend someone told me that this advice is for dry sumps only........help!!!!! now more worried than ever R Why do you need more power? said SWMBO not understanding at all Link to comment Share on other sites More sharing options...
wild bill Posted June 19, 2007 Share Posted June 19, 2007 caterham oil Pressure sender very unreliable either change it or better still fit mechanical pressure guage and do away with the rubbish from Caterham Check oil with engine warmed up and running Next service get rid of the foam sump baffle in the sump as well. If pressure still low then worry Search techtalk with oil pressure as the subject line over the last 2 years and all will come up endlessly 😬 Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted June 19, 2007 Share Posted June 19, 2007 There has been several topics on the subject of oil pressure lately - sure you will find them if you do a 'search' in Tech Talk. 4 bar is normal when cold and when at high revs. Falls to around 2 bar when idling and hot. Mine (wet sump) says check with engine hot and running too ?! ****************** And you run and you run to catch up with the sun, but it's sinking... And racing around to come up behind you again. photos Link to comment Share on other sites More sharing options...
Area Representative Paul Richards Posted June 19, 2007 Area Representative Share Posted June 19, 2007 As already stated the oil pressure senders are v. poor. Also foam baffle can break up and block the pick up. Do you know when baffle was changed? Suggest you drop sump to look at it. I can help if needed. Edited to say - Yes you do check oil level when hot and running. Paul Richards Area Representative - L.A.D.S.

Billyboy Posted June 19, 2007 Share Posted June 19, 2007 Also 4 when cold and drops to between 2 and 4 when hot My car having covered 5000 miles now I have changed the sump baffle about 1000 miles ago and the old one was in great shape, No breakup whatsoever! Car has always been run on caterham comma synthetic oil and I am lead to beleive this is why I have no problems with the foam.......................BUT *rolleyes*who knows for sure! One thing is for definite you need to check the baffle as a break up could possible result in a new engine.............. Link to comment Share on other sites More sharing options...
Dave Rothwell Posted June 19, 2007 Share Posted June 19, 2007 Richard, Almost sure to be the oil pressure sender - they seem to be Junk - My oil pressure dropped a couple of years ago when the engine had only about 6000 miles on it. Changed the sender and all was well. Now dropping again I notice. Hardly moves the gauge on tick over - I dont take any notice anymore. Cheers.

Richards 7 Posted June 19, 2007 Author Share Posted June 19, 2007 So i will check the sump in a week or so when I have the time. In the meantime If I decide to change the gauge should I change just the sender or chuck the whole lot. In that case what about a combined oil temp and pressure gauge? There is a racetech one on demon tweeks is that a decent one???? sorry but a numpty on this R Why do you need more power? said SWMBO not understanding at all Link to comment Share on other sites More sharing options...
jono Posted June 19, 2007 Share Posted June 19, 2007 Richard, Your answers are in my previous thread here (sorry can't do a clicky) http://blatchat.com/T.asp?id=132970 Link to comment Share on other sites More sharing options...
DMT Posted June 19, 2007 Share Posted June 19, 2007 Hi, I've noticed my oil pressure has dropped. It was running just above 4 cold and at full chat - just under 2 at tickover.# Now it's running just below 4 as above and just out of the red on tick over! I've done 2500miles (of which 4 track days 2 sprints and 1 race) is it buggerd??? Link to comment Share on other sites More sharing options...
shn7 Posted June 20, 2007 Share Posted June 20, 2007 DMT, switch to a mechanical set up and forever remove the doubt as to whether the sender is burgered or not. £80 well spent IMHO. Steve.
