LostSoul Posted November 17, 2023 Share Posted November 17, 2023 Hi there. Can someone here please let me know a part number for the correct oil pressure sender/sensor/switch for a '73 1.9, RHD Manta? I have read everything I can find here and elsewhere and several options have surfaced. I just don't know which is the right one for me! Better still, if you have one for sale, please let me know. (Trying to work out why gauge flips right over to max+ as soon as ignition goes on - there's some reference here but for a 'skilled-owner' fix. As I have zero car-fixing skills, I need to source any possible parts involved ready for a visit to the workshop) Thank you 🙂 LS Quote Link to comment Share on other sites More sharing options...
Jessopia74 Posted November 17, 2023 Share Posted November 17, 2023 @MrCarlos Sure he had them available when someone else was asking? 1 Quote Link to comment Share on other sites More sharing options...

1200bandit Posted November 17, 2023 Share Posted November 17, 2023 Had this problem very hard to get,got a used one ,replaced the wiring upto the bulk head 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted November 17, 2023 Share Posted November 17, 2023 yes 100% on all the above answers. hard to find a used one or even the correct new one but usually its the wires / and or the connections. dont know what access is like on the 'a' but its all doable on a b without having to remove anything.a short or shortened spanner helps a lot .obviously removing the exhaust front pipe or manifolds makes it a hell of a lot easier but its more work and gaskets and ive always managed without ! 1 Quote Link to comment Share on other sites More sharing options...
LostSoul Posted November 18, 2023 Author Share Posted November 18, 2023 Thank you all for these responses. We'll check the wiring first, and cross fingers for a result there! More questions coming soon 🙂 Thanks again. 1 Quote Link to comment Share on other sites More sharing options...
1200bandit Posted November 18, 2023 Share Posted November 18, 2023 Did try with the exhaust manifold on very easy to remove the old sensor trying to fit the replacement one 4 hours later removed the manifold ( about 1/2 hour) and easy to fit ,replaced the wiring as well Quote Link to comment Share on other sites More sharing options...

1200bandit Posted November 18, 2023 Share Posted November 18, 2023 Yes it’s heat sleeving from a 02 sensor which run under the DPF from a Renault Quote Link to comment Share on other sites More sharing options...
MrCarlos Posted November 18, 2023 Share Posted November 18, 2023 I have good used oil pressure sensors at £35 plus postage. As others have pointed out though check the wiring and connectors first 1 Quote Link to comment Share on other sites More sharing options...
1200bandit Posted November 19, 2023 Share Posted November 19, 2023 If you need information on how to remove the exhaust manifold you will the information on here The manifold bolts are 15mm and will need a flexible jiont for the rear bolts which are a bit fiddly. 1 Quote Link to comment Share on other sites More sharing options...
