cam.in.head Posted January 5, 2023 Share Posted January 5, 2023 autocorrect made that unreadable ! above the oil filter is a blank plug. used for priming the filter but in reality this plug is never used for such purpose and becomes absolutely stuck solid. they are not a particularly strong grade of metal either !. i beleive in the 2.4 frontera engine they fit it on the other side above the oil pump ? ? ive had very little sucess removing them over the years. 1 Quote Link to comment Share on other sites More sharing options...

Never knew that was what the plug was for above the oil filter. Like everyone else I guess, I just fill my filters with oil before fitting. You're right about the 2.4 Frontera engine - arrowed in this pic. Shame those allen key plugs are so darn tricky to remove. I did several rebuilds of the oil pump on my 2.0 CIH and the plug above that is what you're supposed to remove to prime the pump before running. Had to just grease the pump gears instead while trying to keep everything else grease free including the anaerobic sealer on the mating faces. Right pain in the proverbial! 😠 Project images are available to Club Members Only, Click to become an OMOC Member.

1200bandit Posted January 7, 2023 Author Share Posted January 7, 2023 Remove the wiring from the pressure sensor, wire up the new sensor,earth it to battery,and now l have a oil light on the dash. The wiring can go the wrong way around and then on oil light on dash 2 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted January 7, 2023 Share Posted January 7, 2023 (edited) when i get chance i will double check on my spares pile but im pretty sure that gallery that runs along the left side of the engine (from standing infont) is purely to feed the main crank journals.and the plug above the oil filter is basically at one end of it.the original pressure switch being at the other end.so the pressure along its entire length should remain constant and regulated by the overpressure valve.the feed up to the head and timing chain comes up the timing case cover itself. but like has been mentioned.the plug is usually impossible to undo anyway and once the pressure sensor is fitted in its original place with new wires it should be ok for many years anyway. it can be removed and refitted with all the manifolds and exhaust in place with a suitable spanner .even the angle piece. tricky yes but better than removing other bits if you dont need to ! all reachable from the gap at the side of the brake master cyl. 7 minutes ago, 1200bandit said: Remove the wiring from the pressure sensor, wire up the new sensor,earth it to battery,and now l have a oil light on the dash.

H-400 Posted January 8, 2023 Share Posted January 8, 2023 (edited) I'm happy with our "continental" Manta's. No brakemaster cilinder/booster, no steering collumn/rack on that side. And our exhaust manifold is wider to the outside. Makes fiddeling on that oil contact easier: Project images are available to Club Members Only, Click to become an OMOC Member. When I notice that 7mm hex plug is stuck: Make sure it is clean so you can fit the key completely in, don't use a worn key or one that is already "bended". Best of all a hexagon socket that you can tap with a hammer. Edited January 8, 2023 by H-400 2 Quote Link to comment Share on other sites More sharing options...

Yeah, it’s very tight in the RHD cars to get everything fitted in there, tbh opel design did a great job originally 1 Quote Link to comment Share on other sites More sharing options...

Jessopia74 Posted January 9, 2023 Share Posted January 9, 2023 Think they are NPT iirc. Think I got a 1/4BSP to 1/8NPT elbow for one 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted January 9, 2023 Share Posted January 9, 2023 the one you have got is probably for carlton/ senator because they dont need the elbow piece. 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted January 10, 2023 Share Posted January 10, 2023 now its off and you see its relatively easy,why not solder your new wires straight onto the original unit and try it ? it will more than likely be ok . sorry if you do it and it isnt but worth a try ! 1 Quote Link to comment Share on other sites More sharing options...

cam.in.head Posted January 10, 2023 Share Posted January 10, 2023 im pretty sure they are m10x1. straight.with a copper sealing washer. as far as i know the thread size is stamped on the size where the spanner fits. block is m14 for the adapter /elbow piece. 1 Quote Link to comment Share on other sites More sharing options...

cam.in.head Posted January 20, 2023 Share Posted January 20, 2023 the right angled adapter thats already in the engine is on a tapered thread anyway so can be loosened or tightened a small amount either way if clearance is an issue. looks like all should be ok there. 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted January 21, 2023 Share Posted January 21, 2023 forgive me not understanding the imogies or whatever they are called. dont understand the grinning face .or have i misunderstood. ! the info i gave was true. the adapter can be moved a little either way .mine has the sensor pointing at eleven oclock .
